Keep southern islands' natural and spiritual wealth

Letter from Malcolm Tan, Straits Times Forum 14 Aug 08;

I REFER to yesterday's article, 'Southern islands at crossroads'. I read with alarm that the departure of Mrs Pamelia Lee as managing director of Sentosa Leisure Group (SLG) may jeopardise the eco-paradise potential of the southern islands. It is indeed sad to learn that Mrs Lee seems to be the 'lone voice' in SLG, fighting for the preservation of the natural heritage of the southern islands.

I have stayed on St John's Island and crossed to Lazarus Island many times, and my photos attest to the fact that the two islands have much natural and spiritual wealth to offer Singaporeans and foreigners that cannot be found elsewhere on the mainland. Amid our hectic urban schedules, my friends and I have always found our spiritual refuge on the two islands with their many naturally therapeutic highlights.

The seas around the two islands are amazingly clear at certain times of the year and support much marine fauna and flora that are rare on the mainland. Many of these can be seen clearly on an especially low tide. One of our last stretches of natural coastal rocky shores in Singapore is also found here, with plenty of intact seashells lying buried in the soft sand. There is even a stretch of naturally soft sand bar on Lazarus Island, where one can walk to an outlying rock without getting completely submerged, even at high tide.

Moreover, nowhere else in Singapore can one see as many as 18 Brahminy Kites soaring gracefully in the air, spotting for prey and even occasionally diving down to the sea to take fish out with a quick and well-timed swoop. Add to these, the spectacular 'red ball' sunset over the open sea and the occasional sighting of pink dolphins in the water and one can understand why these islands are so magical.

The many Singaporeans and foreigners I met on the islands all agreed the authorities should preserve them in their natural state for posterity. It would be sad indeed if these islands are converted into another casino or another rich man's exclusive playground. That would be the sad day when most ordinary Singaporeans like me cannot claim the southern islands are part of our homeland as we have no access to their natural beauty. When that happens, the authorities should not be surprised if some of us choose to seek 'greener pastures' elsewhere. For we would then have truly seen that this country is an elitist one, where only dollars and cents matter, despite all the recent hype about the importance of work-life balance, nature conservation and eco-tourism.

Malcolm Tan,

Sorry for the typing error of your name. Deepest apology.

Malcom Tan,

Your letter moves me, bringing back my memories and nostalgia of my earlier years.

As an Australian now [living 2 km from a NSW beach], I fully share and empathize with your concerns and feelings for the eco-paradise of Singapore's southern islands.

A walk along the sandy coast has therapeutic effects after a hard day's or a hard week's work. The Southern Islands offer a "relatively cheap" getaway for the whole family. And there is no passport or immigration-check hassle, no strict dress code, etc.

Thanks for your letter, and have a nice day.

We got to pay to step into Sentosa even though it is part of Spore. paying to get into attractions is fair enough but can't I just stroll over into Sentosa without having to pay or is it not part of our homeland - for the exclusive high ended only?

Creating a Coral Paradise in Singapore Within 10 Years

ZaoBao.com 12 Aug 08;
translation from the ashira blog

Members of the International Year of the Reef (IYOR) Singapore Organising Committee have a dream, and that is to create a coral paradise in Singapore within the coming years.

Professor Chou Loke Ming (Department of Biological Sciences, National University of Singapore believes that even though it would be difficult to achieve the aim of "Singapore, Coral Paradise 2018", it is not impossible. If this dream can be achieved, Singapore's marine life would be revived, with all kinds of fish returning, allowing us to become a diving hotspot.
He expressed these thoughts during the launch of the International Year of the Reef (IYOR).

IYOR is celebrated once every 10 years, and the first IYOR was launched in 1997, with the aim of raising awareness about the destruction of coral reefs. At that time, various groups from over 50 countries were involved and more than 100 research publications arose from the event.

The various groups and organizations taking part in this year's IYOR are equally enthusiastic and passionate, and comprise of many NGOs, water activity interest groups, individuals, as well as the National Parks Board.When interviewed, the chairman of the IYOR Singapore Organizing Committee, Mr Francis Lee, mentioned that, "The protection and conservation of Singapore's green spaces has been done very well, and air quality has been managed adequately. However, when it comes our marine heritage, too little has been done."

Development of the Blue Plan
With this aim in mind, the committee drafted a Blue Plan 5-6 years earlier, with the hopes of being able to work together with the government in conserving Singapore's marine life.

This year, the committee will once again draft out a new Blue Plan, including discussions/suggestions on how to allow ordinary people to treasure the ocean, as well as to share the knowledge of marine ecology with fishermen and divers alike. For example, if a caught fish is deemed too small, the fishermen could release them back to the sea.

The Chairman of the Blue Plan cluster, Mr Farid Hamid, states that the committee aims to submit the Blue Plan to the government by the end of this year, and have various discussions with the government, including a proposal for marine protected area(s), similar to Sungei Buloh Wetlands Reserve, situated on mainland Singapore.

Situated in the south of Singapore, Sisters' Islands and Pulau Hantu are both within the consideration of the Blue Plan. These two islands are established offshore leisure grounds.

The committee members also aim to organize the existing database of our coral reefs, as well as to update the information, with the eventual aim of setting up a national database of Singapore's coral reefs.

60% of our local coral deaths due to reclamation works
Professor Chou also notes that the Tuas-Jurong area of Western Singapore originally possessed a large area of coral reefs but is now reduced to 40% of its original area.

Sedimentation reduce photosynthesis
Around 60% of Singapore's coral reefs have been destroyed between the 1970s and 1990s, with the main culprit of this destruction being sediments resulting from reclamation works.

Some of these sediments assumulate on the coral reefs, smothering the hard corals, and reducing light penetration which in turn decreases photosynthesis within the corals, leading to the eventual death of these coral colonies.

In addition, when the sediments settle on the seabed, they would also cover any coral larvae (and gametes) present, preventing the growth of new coral colonies.

Mr Ivan Choong, an avid diver who dives frequently in Singapore, said that the silt accumulating in on the seabeds of local waters can be as deep as a human's arm length, and the visibility of local waters are generally low. He notes that when diving locally, visibility is usually around 3-5m, and that he can only see the vague shadow (lacking a distinct outline) of his dive buddy.

Having just returned from Christmas Island, Ivan observed that in comparison, the waters there are still crystal clear even at depths of 30-40m.

Decrease in population but diversity still maintained
Even though Singapore's coral reefs have decreased in numbers, the types of corals that have persisted are largely intact. Professor Chou said that despite having experienced so many years of harsh conditions, only one out of the 251 species of hard corals found locally has gone extinct. This is a pleasant surprise, giving hope and confidence in the dream of a local coral paradise.
Little facts about hard corals

  • Corals are animals, not plants
  • Many individual coral polyps form a single coral colony
  • The intestinal cavity of individual coral polyps contain unicellular sumbiotic algae (zooxanthellae). These algae make use of sunlight that penetrates the water for photosynthesis, and their waster products act as nutrients for the coral
  • Corals absorb calcium that is present in seawater, secreting this calcium in the form of calcium carbonate (CaCO3) skeletons
  • Coral mass spawning occurs annually in Singapore on the nights of full moon during the months of March-April
  • Coral reefs are natural habitats that support one of the greatest number of plant and animal species on earth, and are thus, of utmost importance to biodiversity.

'If I don't collect cans, I will not have food'

Karung guni woman refuses to give students her empty cans
Genevieve Jiang, The New Paper 14 Aug 08;

IT was all over a drink can. And an empty one at that.

The debate: Who should have it?

It began when a group of students went out to look for empty drink cans for a TV challenge.

Their task was to collect at least 8,500 empty cans so they can be painted and stringed together to form a gigantic Singapore flag.

The aim was to get into the Singapore Book of Records, by breaking the last record of 8,470 cans set in 2006.

Groups of students from Fuhua Secondary, Hwa Chong Institution, Innova Primary and Townsville Primary fanned out to look for the cans.

Their search was filmed in last Tuesday's episode of The Records Challenge on Channel 8.

Students from Fuhua were filmed asking a karung guni woman for some empty cans, but she refused.

Later, the students also had to give up some empty cans they had found to the woman.

One of the students cried.

Some viewers said it was wrong of the students to ask the woman for the cans.

A 31-year-old business development manager, Foo Tze Wei, said: 'To the students, the cans were to break a record. But for the woman, every can contributes to her three meals.'

Housewife Lee Yew Huang, 63, agreed, adding that it was insensitive of them to ask the woman for the empty cans.

She said: 'They must realise that it's not easy for old people to make a living this way. It was not justified for the student to cry just because she couldn't get the cans.'

But another viewer, a 24-year-old undergraduate Darren Tan, did not think the students did anything wrong.

He said: 'The students were just trying to complete their assignment. And it's not like they snatched the cans from the woman or were rude to her.

'I think it's commendable that they gave up the cans that they found to her, and even gave her some money.'

The programme's host Pornsak also defended the students.

He told The New Paper that the students had gone to several coffee shops before finding the empty cans.

Pornsak said: 'It was a weekday afternoon and there were very few customers at the coffee shops and hawker centres. The students were doing this after class, so they could have been tired.

'One of the students had set herself a target of 500 to 600 cans within an hour. She thought it was going to be an easy task at first, but it turned out otherwise.

'She could have wept out of tiredness and disappointment.'

He added that the students, together with the filming crew, even bought noodles for the woman.

During filming, students from Fuhua were scouring a Jurong hawker centre for cans when a male student saw the woman, in her 50s, collecting cans.

He asked her for some of her cans but she refused, saying that she depended on the cans for a living. The students then continued their search within the hawker centre.

When they finally found some empty cans, the same woman approached them and asked them to let her have them.

The woman said: 'Can you let me have the cans, please? Have a kind heart. If I don't collect enough cans, I won't have food to eat today.

'You are still young and can continue to hunt for cans. And there are so many of you, whereas I'm alone.'

When contacted, a spokesman for Fuhua said: 'The students gave away the six cans they found to the old woman.

'Before the students went out to collect cans, they didn't know how hard it was for these elderly people. Now, they do.'

Chinese evening daily Lianhe Wanbao interviewed several karung guni women and they said that collecting cans was a difficult living.

A 80-year-old woman, who wanted to be known only as Madam Feng, collects cans at the Chong Pang market every afternoon.

She said she works seven hours a every day, but earns just between $10 and $20 a week.

Another woman in her 70s, who sources at Sengkang, said she sometimes has to compete with students and other welfare groups who are trying to raise money or collect materials for recycling.

Madam Feng said: 'These young people are strong and energetic. How do we compete with them?'

Five new chikungunya infection cases reported

Lynlee Foo, Channel NewsAsia 13 Aug 08;

SINGAPORE: Five more people have caught the chikungunya virus in Singapore, said the Ministry of Health (MOH), and none of them have travelled overseas recently.

They include two foreign workers at Kranji Way – a 48-year-old worker who works and lives at the Kranji site and a 34-year-old worker who has gone to Kranji Way several times.

This brings the total number of cases linked to the Kranji Way cluster to 30.

Separately, a 31-year-old foreigner who works at Sungei Kadut Street 6 also contracted the mosquito-borne disease. Health officers have screened the worker's colleagues, as well as those he lives with. None of them have been tested positive.

Authorities also reported chikungunya infection cases in Yishun and Hougang. A 20-year-old accounts assistant living in Hougang Street 22 was admitted to hospital on August 7, but he has since recovered.

Another victim is a 42-year-old contractor who lives in Yishun Avenue 5. He fell ill late last month, but has also recovered after seeing a doctor.- CNA/so

Five new cases of chikungunya
Lee Hui Chieh, Straits Times 14 Aug 08;

THE largest cluster of chikungunya cases in Singapore continues to grow, with five new cases reported.

Two more people came down with the mosquito-borne disease at Kranji Way, bringing the total number affected there to 30, the Health Ministry said yesterday.

The latest hit are a 48-year-old Indian national who lives and works in the area, and a 34-year-old Chinese national who visited the area several times to collect materials for his company.

Both men were hospitalised and have since recovered.

At least 10 National Environment Agency (NEA) officers cleaned up the areas surrounding the Chinese national's home and workplace. They checked 10 factories and destroyed 31 mosquito breeding sites.

The NEA had already stepped up efforts to stamp out mosquitoes along Kranji Way. Following the latest cases, it has expanded the blitz to Kranji Loop, Kranji Road, as well as Kranji and Sungei Kadut industrial estates.

Fifteen NEA officers and 20 private pest control operators - seven times the usual number - have been deployed, They have checked more than 38 factories and destroyed mosquito breeding sites in 33 of them.

A third man, living in Sungei Kadut Street 1, was also diagnosed with chikungunya. The 31-year-old Bangladeshi, who works at Sungei Kadut Street 6, was hospitalised on Aug 6, three days after developing symptoms such as fever and joint pains.

Two other recent cases have also been reported in other areas.

A 42-year-old contractor living in Yishun Avenue 5 fell ill on July 26, but recovered after seeing a doctor.

He is Yishun's second chikungunya patient. Another man, living in Miltonia Close, had fallen ill a week before.

Joining them was an accounts assistant living in Hougang Street 22. He fell ill last Tuesday and was hospitalised two days later. Hehas since recovered.

The five latest patients were probably bitten by infected mosquitoes here, as they had not left Singapore recently.

They bring the tally of local cases to 54, spread over 11 areas on the island.

Before this year, nobody had ever caught the disease in Singapore. Thirteen people had been infected while abroad in 2006 and last year.

The health and environment authorities here are fighting to prevent chikungunya, which has migrated from Africa and India to South-east Asia, from being entrenched in Singapore.

More chikungunya cases, new clusters?
Alicia Wong, Today Online 14 Aug 08;

ONE IS a 42-year-old contractor living in Yishun, another is a 20-year-old accountant from Hougang, and the third is a 31-year-old Bangladeshi worker based in Sungei Kadut.

What they have in common: They have been infected with the chikungunya virus, did not recently travel overseas and moved about mostly in the vicinity of their residence and work place.

The contactor, who stayed at Yishun Avenue 5, had developed symptoms on July 26. This was about a week after a25-year-old Chinese National living at Miltonia Close, just off Yishun Ave 1, showed signs of chikungunya fever, as reported earlier.

Both the contractor and the accountant, who developed symptoms on Aug 5, have recovered. None of their household contacts tested positive for chikungunya.

Meanwhile, the Bangladeshi worker developed symptoms on Aug 3 and was admitted to hospital three days later.

The Ministry of Health (MOH) tested 124 of his household contacts and co-workers at Sungei Kadut, and none testedpositive.

Last week, a 40-year-old Chinese National living in Sungei Kadut was found to be infected. Sungei Kadut Drive is just off Kranji Way, where the largest cluster so far of chikungunya cases exists.

Yesterday, the MOH said two more foreign workers at Kranji Way — an Indian and Chinese National — were found to be infected, making a total of 30 cases in the cluster.

Could three new clusters emerge, given the latest new cases?

“Certainly there is a huge concern,” said general practitioner, Dr Chong Yeh Woei, who noted that the main worry is that chikungunya could become endemic, like dengue. “How do you get rid of it?”

The MOH told Today the new cases could be due to ongoing outbreaks in the region and more foreign workers and tourists coming here, as well as Singaporeans going overseas. It is investigating to determine possible links between the incidents and their implications.

In the view of Associate Professor Leo Yee Sin, the head of department of Infectious Diseases at Tan Tock Seng Hospital: “Containing chikungunya ... needs to take a regional and global view.”

Singaporeans are vulnerable to infection because of our low immunity, and active chikungunya transmission in areas we frequent, she added. To date, 103 cases have been reported to MOH, of which54 are instances of local transmission.

UK fishing boat filmed dumping 5 tons of fish

Paul Eccleston, The Telegraph 13 Aug 08;

A UK fishing boat has been caught on film dumping tons of unwanted fish into the sea.

A Norwegian coastguard vessel took video footage of a Shetland boat discarding about 80 per cent of its catch.

Under EU rules the trawler Prolific had no choice to but to get rid of the fish because they were the wrong type.

The film of the discard at a time of diminishing fish stocks and food shortages has caused outrage in Norway which is not an EU member.

Norway bans the dumping of fish in its own waters but the Prolific - which caught the fish legally in Norwegian waters - waited until it reached British waters in the North Sea before dropping an estimated five tons of fish overboard.

In the film a steady stream of fish mostly saithe - a relative of the cod - can be seen being pumped out of the hold and hands are also seen emptying boxes of fish over the side.Norwegian Fisheries and Coastal Affairs Minister Helga Pedersen slammed the incident and said she will now demand that all foreign vessels fishing in Norwegian waters must land all fish caught at whatever port the boat docks in.

She described discard as one of the most serious threats to sustainable management and added:

"Discard is a terrible practice. In addition to the moral aspects of this sheer waste of food, discards lead to unrecorded catches, which lead to incorrect fisheries statistics, which again disrupt the basis for scientific assessments of stocks and scientific advice on management."

Greenpeace Oceans campaigner Willie MacKenzie said: "The best scientific advice is that we shouldn't be fishing for cod at all because stocks have been so depleted in the North Sea and yet here we have tons of fish being dumped overboard.

"Discard is happening all the time but normally it takes place at sea where nobody can see what is happening. This incident has to be multiplied many, many times to get an idea of the scale of the waste.

"The fishermen would say it happens because quotas are too small and they have to throw fish back but you would have to be insane to agree with that argument."

The incident on August 2 has also led to angry exchanges on websites with one Norwegian claiming:

"It is morally wrong and its just p***ing in your own bed. This has been illegal in Norway since the eighties and the boat would have been arrested had it done it in the Norwegian sector. It is just calculated environmental criminality. The whole thing is very provocative, disappointing and shocking."

But Hansen Black, chief executive of the Shetland Fishermen's Association, said the Prolific had been caught between a rock and a hard place.

"The system forces fishermen to go to a place they are unfamiliar with to seek the fish they have quotas for. Unfortunately in this case they landed a quantity of saithe which they didn't have a quota for.

"If they had dumped it there and then they would have been breaking Norwegian laws and if they had landed it back in the UK they would have been fined.

"They did the only think they could do which was to steam 100 miles away - wasting time and fuel - to an area where they hoped to find the type of fish they are entitled to catch and where they could legally dump the saithe.

"This is a horrible indictment of the system fishermen have to operate under. These are young men under massive pressures trying to make a living. No fisherman wants to dump fish - his job is to find fish for people to eat - not to see it thrown over the side."

A Defra spokesperson said: "Throwing dead fish back into the sea is a waste that nobody wants to see, but there is no easy answer.

"UK fishermen have shown that they are committed to finding new ways of protecting vulnerable stocks, and the European Union has backed a UK action plan designed to reduce the amount of discards.

"The UK is keen to ensure more effective and sustainable fisheries by reducing by-catch and discards, and the Government is working closely with fishermen to achieve that."

Film of fishermen dumping catch causes uproar
A UK trawler filmed throwing five tonnes of fish overboard has caused outrage in Norway and among environmentalists

John Vidal, guardian.co.uk 13 Aug 08;

A British trawler has sparked an international incident after being filmed taking a boatload of endangered fish caught in the Norwegian sector of the North Sea and then dumping the majority overboard in UK waters.

Norwegian government coastguards filmed the crew of the Prolific, a Shetland-based trawler, openly discarding more than 5,000 kg of cod and other dead white fish, or nearly 80% of its catch.

According to the coastguard, the boat had previously been inspected in Norwegian waters and declared legal, before crossing into UK waters where it dumped its load. The incident took place on 2 August but the video only came to light in Britain yesterday.

It is illegal to discard fish in Norwegian waters, but boats are forced to do so in European Union waters if they have caught the wrong species of fish or fish that are too small. Last year the EU estimated that between 40% and 60% of all fish caught by trawlers in the North sea is discarded. The practice of dumping is widely recognised as unsustainable but inevitable given the present EU quota system.

Yesterday, Norwegian minister for fisheries and coastal affairs Helga Pedersen, speaking to angry fishing communities in northern Norway who had seen the film, said she would press for review of the EU fishing policy and wanted to ban any boat discarding fish that were caught in Norwegian waters.

"Discarding fish not only means a massive waste of food and potential income, it also leads to unrecorded catches, resulting in a poorer scientific basis for our management decisions", she said. "I want a requirement that all fish caught in Norwegian waters, also by foreign vessels, must be taken to port, regardless of which final port is used. We will introduce new requirements, as a condition for obtaining licenses to fish, that vessels cannot discard valuable fish caught here".

Reidar Kaarbø, an independent analyst of Norwegian government policy said: "This must stop now. The EU community cannot be taken seriously if it allows this kind of behaviour. This is certainly not how to manage the world's resources."

UK fish experts said the practice of discarding fish was common but had rarely been so dramatically documented. Opinions were split on whether the Prolific was discarding fish for which it had no quota, or that it was "high-grading" its catch. This involves boats discarding low-value small fish to make room for high value larger fish.

"It is a disgrace. This practice is depleting populations that are already overfished and it is happening everywhere", said Willie MacKenzie, Greenpeace fisheries campaigner. "All of these fish are perfectly marketable, and have been legally caught. But if you are a fisherman it makes more economic sense to take boat to market with the most saleable fish, so you discard the lowest value stuff."

European Union quotas strictly limit the amount of fish that ships can bring back to port, but there is no restriction on the amount of fish they can catch.
The current EU quota system for fish sets quotas at individual species level, which are then allocated and traded amongst individual fishermen. Often they will buy quotas out at sea once they know what they are catching. This means that it is illegal to take back to port fish they have no quota for so these fish are discarded.

The solution, say environment groups, involves an overhaul of fisheries management, making discards illegal, and encouraging more sustainable fishing methods.

Yesterday, the Prolific could not be contacted but the ship's agents, LHD Ltd of Lerwick, said that it was rare for it to fish in Norwegian waters. "It is out of contact. We very rarely fish in Norwegian waters. That's the first time in years," said managing director Richie Simpson. "The reason there are discards is the ridiculously low quotas. Fishermen cannot make a living with them. They are at a ridiculous level."

The International council for the exploration of the sea, the leading scientific body for fisheries scientific, has repeatedly advised the EU that stocks of cod in the North Sea are much too low to be fished and has argued for no-go areas. However, every year the European government ministers override their advice and continue with a quota system.

A spokesman for the department of the environment, food and rural affairs (Defra) said: "Throwing dead fish back into the sea is a waste that nobody wants to see, but there is no easy answer. The UK is keen to ensure more effective and sustainable fisheries by reducing by-catch and discards, and the government is working closely with fishermen to achieve that."

Mass Extinctions And 'Rise Of Slime' Predicted For Oceans

ScienceDaily 13 Aug 08;

Human activities are cumulatively driving the health of the world's oceans down a rapid spiral, and only prompt and wholesale changes will slow or perhaps ultimately reverse the catastrophic problems they are facing.

Such is the prognosis of Jeremy Jackson, a professor of oceanography at Scripps Institution of Oceanography at UC San Diego, in a bold new assessment of the oceans and their ecological health. Jackson believes that human impacts are laying the groundwork for mass extinctions in the oceans on par with vast ecological upheavals of the past.

He cites the synergistic effects of habitat destruction, overfishing, ocean warming, increased acidification and massive nutrient runoff as culprits in a grand transformation of once complex ocean ecosystems. Areas that had featured intricate marine food webs with large animals are being converted into simplistic ecosystems dominated by microbes, toxic algal blooms, jellyfish and disease.

Jackson, director of the Scripps Center for Marine Biodiversity and Conservation, has tagged the ongoing transformation as "the rise of slime." The new paper, "Ecological extinction and evolution in the brave new ocean," is a result of Jackson's presentation last December at a biodiversity and extinction colloquium convened by the National Academy of Sciences.

"The purpose of the talk and the paper is to make clear just how dire the situation is and how rapidly things are getting worse," said Jackson. "It's a lot like the issue of climate change that we had ignored for so long. If anything, the situation in the oceans could be worse because we are so close to the precipice in many ways."

In the assessment, Jackson reviews and synthesizes a range of research studies on marine ecosystem health, and in particular key studies conducted since a seminal 2001 study he led analyzing the impacts of historical overfishing. The new study includes overfishing, but expands to include threats from areas such as nutrient runoff that lead to so-called "dead zones" of low oxygen. He also incorporates increases in ocean warming and acidification resulting from greenhouse gas emissions.

Jackson describes the potently destructive effects when forces combine to degrade ocean health. For example, climate change can exacerbate stresses on the marine environment already brought by overfishing and pollution.

"All of the different kinds of data and methods of analysis point in the same direction of drastic and increasingly rapid degradation of marine ecosystems," Jackson writes in the paper.

Jackson furthers his analysis by constructing a chart of marine ecosystems and their "endangered" status. Coral reefs, Jackson's primary area of research, are "critically endangered" and among the most threatened ecosystems; also critically endangered are estuaries and coastal seas, threatened by overfishing and runoff; continental shelves are "endangered" due to, among other things, losses of fishes and sharks; and the open ocean ecosystem is listed as "threatened" mainly through losses at the hands of overfishing.

"Just as we say that leatherback turtles are critically endangered, I looked at entire ecosystems as if they were a species," said Jackson. "The reality is that if we want to have coral reefs in the future, we're going to have to behave that way and recognize the magnitude of the response that's necessary to achieve it."

To stop the degradation of the oceans, Jackson identifies overexploitation, pollution and climate change as the three main "drivers" that must be addressed.

"The challenges of bringing these threats under control are enormously complex and will require fundamental changes in fisheries, agricultural practices and the ways we obtain energy for everything we do," he writes.

"So it's not a happy picture and the only way to deal with it is in segments; the only way to keep one's sanity and try to achieve real success is to carve out sectors of the problem that can be addressed in effective terms and get on it as quickly as possible."

The research described in the paper was supported by the William E. and Mary B. Ritter Chair of Scripps Institution of Oceanography.

A recipe for saving the world's oceans from an extinction crisis
EurekAlert 13 Aug 08;

Simply enforcing fisheries regulations would go a long way to preventing species extinctions.

Jeremy Jackson, senior scientist emeritus of the Smithsonian Tropical Research Institute and the Scripps Institution of Oceanography, asserts in the Aug. 12 issue of the journal Proceedings of the National Academy of Sciences, that the following steps, if taken immediately, could reverse the demise of the oceans: Establish marine reserves, enforce fishing regulations, implement aquaculture, remove subsidies on fertilizer use, muster human ingenuity to limit fossil fuel consumption, buy time by establishing local conservation measures.

In 2001, Jackson and 18 co-authors published a landmark paper in the journal Science, "Historical Overfishing and the Recent Collapse of Coastal Ecosystems," in which they made the case that environments that we perceive as relatively pristine have, in fact, been radically altered by centuries of human exploitation.

Jackson has been on the lecture circuit since then. "Our amnesia about what is natural is the greatest threat to the environment," said Jackson, in the youTube version of his talk "The State of the Ocean," delivered at Middlebury College, in Vermont, in 2007.

Developing a media-savvy approach, Jackson worked closely with Nancy Baron, Ocean Science Outreach director of SeaWeb/Communication Partnership for Science and the Sea to publicize his work and the work of other ocean scientists.

Later, he collaborated with marine biologist-turned-filmmaker, Randy Olson of "Flock of Dodos" and "Sizzle" fame, to create Shifting Baselines videos for the Web—graphic demonstrations of the way our perception of what a "natural" environment is changes over time.

In this article, "Ecological Extinciton and Evolution in the Brave New Ocean," Jackson reviews a series of studies that bolster initial observations that exploitation and pollution of estuaries and coastal seas, coral reef ecosystems, continental margins and the open ocean continue unabated.

He predicts that overfishing will lead to extinction of edible species and have an indirect effect on other levels of the food chain. Larger dead zones and toxic algal blooms may merge along the coastal zones of all of the continents. Disease outbreaks will increase. Vertical mixing of ocean waters may be inhibited resulting in disrupted nutrient cycles.

"Some may say that it is irresponsible to make such predictions pending further detailed study to be sure of every point. However, we will never be certain about every detail, and it would be irresponsible to remain silent in the face of what we already know."

Despite Jackson's bleak prognosis for a "brave new ocean," he clearly identifies "lack of political will and the greed of special interests" as standing in the way of establishing sustainable fisheries and aquaculture, "Simply enforcing the standards of the Magnuson-Stevens Act and the U.S. National Marine Fisheries Service would result in major improvements in U.S. waters within a decade."

"We have to begin somewhere," says Jackson—who will continue to stir the pot.

Prince Charles accused by scientists of abusing his position over GM food comments

Andrew Pierce and Caroline Gammell, The Telegraph 14 Aug 08;

The Prince of Wales has been plunged into an extraordinary row with scientists after they accused him of seriously abusing his position over his comments on GM food.

Scientists reacted angrily to the warning from the Prince in his interview in the Daily Telegraph that GM crops risked causing the world's worse environmental disaster.

MPs accused him of being a "luddite" who risked inflicting starvation on millions of people in Africa.

But the Prince will be heartened by the revelation that there is now only one GM trial ongoing in Britain - in Cambridgeshire - and there are no plans to licence any more.

Some 54 have been conducted since they were approved by the government in 2000.

Prof Ottoline Leyser, a plant geneticist at the University of York who is a Fellow of the Royal Society, said: "I am disappointed with the whole environmental movement.

"This is rabid anti GM. Misguidedly demonising GM results in the real issues being sidelined, creating the very problems that Prince Charles is trying to address.

"There are several issues that have been muddled together, resulting in serious dangers to the future direction of agriculture.

"He has confused the dominance of multinational companies and its consequences for food security with the use GM in agriculture. If there were a total world ban on GM tomorrow, it would have no effect at all on the dominance on big multinational companies."

Johnjoe McFadden, professor of molecular genetics at the University of Surrey, said: "Prince Charles is talking biased baloney.

"Prince Charles, like many wealthy people, has no concept of the hardships of other parts of the world. He wants to retain his vision of a rural idyll by telling the poor to eat organic cake while he pours wine into the fuel tank of his sports car.

"He is using the privileged position of a prince of the realm to try to influence us with a one sided, irresponsible, view of food technology. He is like a romantic 19th century poet writing and painting pictures of rural life.

"Environmentalists have been saying for years all we need to do is redistribute wealth to feed the poor. It has not happened so we have to produce more food. The most effective way is through GM crops."

Professor Alison Smith, senior researcher at John Innes Centre, Europe's premier plant science laboratory, said: "I was shocked and saddened to read what Prince Charles said. Shocked because it was so ill-informed, one-sided and generally negative.

"Saddened because the Prince is in a position to lead this country in solving some of the massive problems he identifies. He could bring together our world-class scientists and agricultural experts to catalyse constructive debate and action that would benefit the UK and the rest of the planet.

"Instead, he indulges in diatribes in which he appears to blame the problems of the planet on a single technological advance that he has completely misunderstood."

The Prince, in the Daily Telegraph, challenged the view that GM foods will be crucial to the developing world. He said: "What we should be talking about is food security, not food production - that is what matters and that is what people will not understand."

But the Royal Society, in a statement said: "Food security is an important issue. We do need to evaluate a range of techniques and technologies which have been proposed for enhancing food-crop production and the Royal Society is currently undertaking a study looking at this."

In his interview the Prince accused large corporations of conducting experiments with nature, which had "gone seriously wrong".

He was backed by Patrick Holden from the Soil Association who said: "If we go down this path I think we will put this country at risk. There could be a period of great difficulty in the next 10 or 20 years."

Mike Childs, campaign director for Friends of the Earth, said: "GM crops will not solve the food crisis - and forging ahead with an industrialised farming system will continue to fail people and the environment around the world.

Des Turner, a Labour MP on the Commons science committee, said: "Prince Charles has got a way of getting things absolutely wrong. It's an entirely Luddite attitude to simply reject them out of hand."

Phil Willis, the chairman of the Commons science committee, said the Prince's "lack of scientific understanding" would "condemn millions of people to starvation in areas like sub-Saharan Africa".

Why Prince Charles is right about agribusiness
It's easy to scoff at the Prince's latest 'green' intervention, but if you really look at what he's saying, it's completely cogent

John Vidal, guardian.co.uk 13 Aug 08;

Prince Charles' warnings that genetically modified crops and industrial agriculture will lead to ecological disaster appear only to be adding a dose of passion to the cooler analysis of world's leading agronomists, climate scientists and grassroots groups in developing countries, who have been saying much the same about farming and ecology for some time.

When asked whether "industrial scale food conglomerates are the way ahead", he said: "What, all run by gigantic corporations? Is that really the answer? I think not. That would be the absolute destruction of everything."

Anaylsis: Charles echoes Third World Network and Via Campesina, the world's two most authoritative farm analysis groups, and is aiming at global agribusinesses which dominate the food chain, and controls seed supplies, chemicals, and food processing as well as transport and retail sales. He also echoes Food Matters, a report from the No 10 Strategy Unit, which recognises that the agribusiness model of food production based on global competition has failed to deliver.

"Corporations [are] conducting a gigantic experiment with nature and the whole of humanity which has gone seriously wrong. Why else are we facing all these challenges, climate change and everything?"

Analysis: Charles links climate change and world hunger with the growth of agribusiness and its reliance on oil, large amounts of scarce water, and chemicals. The UN, the UK government and the EU recognise that industrial agriculture, including biofuel, soy and palm oil industries, have been responsible for large-scale deforestation, as well as hunger and a growth in carbon emissions, soil erosion and social problems.

The UN's Food and Agricultural Organisation said in 2006: "The [global] livestock business is among the most damaging sectors to the earth's increasingly scarce water resources."

"A nightmare vision ... in which millions of small farmers are driven off their land and into unsustainable unmanageable, degraded and dysfunctional conurbations of unmentionable awfulness."

Analysis: According to UN Habitat, cities are growing by 180,000 people a day and the world's urban infrastructure is unable to cope. Roughly one billion people in Latin America, Asia, and Africa live in slums. The UK government's Commission for Africa said in 2005: "These slums are filled with the unemployed and disaffected. Africa's cities are becoming a powder keg of ... instability and discontent." According to a major UN report in 2003, the greatest underlying reason for the growth in slums has been globalisation.

"We are missing the point. We should be discussing food security, not food production. that is what matters and that is what people will not understand."

Analysis: Charles echoes the G8 world leaders who stated in Japan in July: "We are deeply concerned that the steep rise in global food prices coupled with availability problems in a number of developing countries is threatening global food security." The UN declared in May: "Securing world food security may be one of the biggest challenges we face in this century."

"And if they think its somehow going to work because they are going to have one form of clever genetic engineering after another then again count me out, because that will be guaranteed to cause the biggest disaster environmentally of all time."

Analysis: The UN International Assessment of Agriculture (IAASTD), carried out by 400 leading agronomists and scientists with the help of the World Bank found no conclusive evidence that GM crops increase crop yields or that they were the single answer to global hunger. The report, endorsed by 60 countries including the UK this year, stated that science and technology must be combined with traditional knowledge, working with communities on localised farming solutions.

"Small farmers ... would be the victims of gigantic corporations taking over the mass production of food."

Analysis: The FAO, the World Bank and nearly all international development groups argue strongly that peasant farmers must be helped to produce more food. The World Bank, the UK's National Farmers' Union and the EU all recognise that the growth of agribusiness is linked to a worldwide decrease in the number of small farms.

"I have been to the Punjab where you have seen the disasters that have taken place ..."

Analysis: The Punjab in India was the centre of the Green Revolution which introduced hybrid seeds, intensive irrigation and chemical fertlisers and pesticides in the 1960s and 70s. According to Reith lecturer and Indian ecologist Vandana Shiva: "Today every farmer is in debt and despair. Vast stretches of land have become water-logged desert."

"Look at western Australia. Huge salinisation problems. I have been there. Seen it. Some of the excessive approaches to modern forms of agriculture."

Analysis: The government of western Australia says on its website: "Salinity is one of the greatest environmental threats facing Western Australia's agricultural land, water, biodiversity and infrastructure. It is caused by too much water containing dissolved salts in the wrong places in the landscape."

"I think it's heading for real disaster."

Analysis: Prince Charles is referring to global ecological problems. Here he echoes many climate change scientists, UN figures and politicians. His language – "unmentionable awfulness", etc – may be quaint, but is he the crank some would have us believe him to be? Absolutely not.

Missing the signs of genetic irrelevance
Richard Black, BBC News 13 Aug 08;

Prince Charles usually speaks from the heart; and his latest outpouring on genetically modified crops is expressed in terms that are forthright even for him.

Judging by readers' comments appended to the Daily Telegraph article outlining his position, he has struck a chord.

This should not be surprising. There are few, if any, such divisive subjects in the scientific firmament; and in the UK at least, polls show deep public suspicion.

But the prominence given to the Prince's words across a range of news media prompt the question: is he right?

While he is adamant that food supplied through genetic technologies would be "guaranteed to cause the biggest disaster, environmentally, of all time", he offers not a jot of evidence to support the claim.

GM agriculture is often treated as a single entity which must in its entirety be regarded as good or bad, healthy or unhealthy, environmentally benign or destructive.

In the real world, biology is rarely that simple.

Take the example of gene flow, the spread of introduced genes from a GM plant into non-GM neighbours, either weeds or conventional crops

How likely it is to happen depends on many factors, among them the type of crop, how its genes may be carried (for example by insects), the way farmers manage it, the weather, and whether any related plants are growing nearby.

So even though it has been shown to occur in some situations - for example, between hybrid radishes grown on the farms of Michigan and wild radishes growing nearby - in others, it does not.

Even if gene flow is documented, it does not automatically cause problems.

And that is just one example of an isolated environmental question.

Global trends

Everyone will have their own opinion about the risks involved; and humans are notoriously bad at assessing risk, as evidenced by a common instinct that driving is safer than flying.

But it is clear that if we look at what science tells us, the GM world is considerably more complex than the one Prince Charles has painted; and you can multiply the complexity a thousand-fold if you include all the environmental, social and economic questions.

But the Prince also had some harsh things to say about the modern system of food production and distribution.

There were some apparent omissions and confusions. For example, the Green Revolution crops he mentions - the rice, maize and wheat hybrids developed half a century ago that sent yields through the roof in Asia and Latin America - were not products of genetic technologies but of conventional cross-breeding.

True, problems are now arising with the crops in some areas with water shortages - they are heavy on irrigation - and soil degradation. But the Prince does not mention that the Green Revolution changed India from a country that regularly needed liberal doses of food aid to one that was self-sufficient and food secure.

Nevertheless, many of the issues he raises - pressure on small-scale farmers, the hunger of modern farming methods for water, food security - are all too real in some parts of the world.

Food production, and more especially food distribution, are increasingly in the hands of giant multinational companies. Farming has already had its industrial revolution in developed countries, and the developing world is following suit.

For society and for the environment, this is a much bigger issue than whether those industrialised farms are growing GM or non-GM crops.

Both mean increased use of pesticides and fertilisers, the trading of machinery for human muscle and the consequent loss of labour compared to traditional agriculture.

In Britain, where GM crops have never been widely grown, intensive farming has been a factor behind a wide range of environmental ills ranging from water pollution to biodiversity decline.

European and national schemes that encourage farmers to look after the environment are repairing some of the damage.

Perhaps the most telling comments on the Farm-Scale Evaluations (FSE), the biggest UK trial of GM crops, came after the event from environmentalists who said what was really needed was a trial of intensive versus non-intensive farming methods.

They could have added that such studies might not restrict themselves to environmental questions; it would also be worthwhile investigating social and economic questions, such as whether intensive or artisanal farming benefits the entire economy more, rather than specific players such as supermarkets, and trying to find some objective answers rather than relying on the theologies of rival schools of economics.

Broken promises

Would the uptake of genetically modified crops across the world make these issues worse?

Perhaps. There are conflicting studies from different areas - often prepared by institutions with a vested interest - showing that GM crops either produce higher or lower yields, need a higher or lower chemical input, and generate higher or lower profits for farmers compared to their conventional equivalents.

A few indisputable facts leap out, however. One is that commercial GM farming is dominated by four crops - soybean, maize, cotton, and canola - and has been wholeheartedly embraced by only a few countries, among them the US, China, Argentina and Canada.

A second is that consumers in Europe do not want to eat GM food, which is one reason why farmers in the EU and in regions supplying food to Europe, especially Africa, are not going to be making a large-scale switch any time soon.

A third - and the one most pertinent to Prince Charles' argument - is that the people and institutions behind the technology have failed to deliver on promises to right their original wrongs and develop strains that would benefit people in poorer countries and loosen corporate control.

Almost exactly four years ago, I was in Cologne, Germany to cover the Agricultural Biotechnology International Conference (Abic). Scientist after scientist (many of them working in the commercial sector) told me how companies had messed up by appearing to force GM products on an unsuspecting world, and how narrow the lines of research had been.

A second wave of crops, they pledged, would bring things that people actually wanted and needed, from drought-resistant rice for Africa to vitamin-enhanced fruit for Europeans, and would largely used technologies that did not involve transferring genes from one organism to another.

On a commercial scale, these developments have not arrived.

Earlier the same year, at the Indian Science Congress in Chandigarh, I listened to Indian scientists from the president down explain how national research institutions were going to develop strains with traits such as enhanced nutrition and salt resistance, and give them away to farming communities.

That, also, has not happened.

The strains being grown commercially today have been engineered either to help farmers control weeds through proprietary herbicides or to reduce pest damage, and remain products jealously guarded by the companies that market them.

Against this backdrop it is perhaps not surprising that many commentators on Prince Charles' interview share his apparent view that GM crops would only add to the woes of farmers and the hungry in poorer countries.

But it is also possible to argue that as things stand, GM crops are irrelevant to the wider patterns of increased corporate control of food chains, the stubborn and enduring hunger felt by much of the developing world, and the global trend of environmental decline.

Prince Charles says GMO crops will be "disaster"
Reuters 13 Aug 08;

LONDON (Reuters) - Britain's Prince Charles said on Wednesday the widespread use of genetically modified crops would be the biggest environmental disaster of all time.

The 59-year-old heir to the British throne is well known for supporting organic farming, but his comments published in an interview with the Daily Telegraph were his most outspoken yet on GMO foods.

His views will strike a chord in Britain where biotech crops -- widely grown in North and South America -- have faced significant opposition with concerns centered on food safety and possible environmental impacts.

Charles said multinational food companies were conducting a "gigantic experiment with nature and the whole of humanity which has gone seriously wrong".

If large companies took over the mass production of food, it would hurt small farmers and the environment, while "excessive approaches to modern forms of agriculture" had damaged water supplies in India's Punjab and in Western Australia, he said.

"What we should be talking about is food security, not food production -- that is what matters and that is what people will not understand," he said.

"And if they think it's somehow going to work because they are going to have one form of clever genetic engineering after another, then again count me out, because that will be guaranteed to cause the biggest disaster environmentally of all time."

His comments come as a wave of food inflation has reopened the debate on how science can boost agricultural production.

Critics of GMO crops say they are environmentally unfriendly and could potentially harm those who eat them. But supporters say they can raise yields, cut costs, and provide other benefits to improve food and feed the world's hungry.

Earlier this year Britain's chief scientist John Beddington said GMO crops should not be shunned as agriculture seeks to respond to rising food demand, particularly from China and India, at a time when climate change is expected to hit yields.

Prince Charles sees red over GM crops
Yahoo News 13 Aug 08;

Prince Charles drew criticism with an outspoken attack on industrial farming Wednesday, warning genetically modified food could be the "biggest disaster environmentally of all time."

Charles said millions of small farmers around the world could be driven off their land into "degraded and dysfunctional conurbations of unmentionable awfulness" by the rise of global conglomerates.

The heir to the throne is a long-term supporter of sustainability and locally produced food and often speaks out on environmental issues.

He has an organic farm on his Highgrove estate in Gloucestershire and set up the Duchy Originals brand, which sells exclusively organic produce, in 1990.

But his latest comments have drawn criticism that he is a "Luddite".

The Daily Telegraph journalist who conducted the interview wrote that Charles "let rip" and started "jabbing his finger" and "bouncing in his chair" when asked whether large-scale food production was the future.

"What, all run by gigantic corporations? Is that really the answer? I think not. That would be the absolute destruction of everything and... the classic way of ensuring that there is no food in the future," Charles told the paper.

He added that "clever" genetic engineers had put the world on course for the "biggest disaster environmentally of all time."

The world should be working "with nature. We have gone working against nature for too long," Charles said.

Labour lawmaker Des Turner, who is on the House of Commons science and technology select committee, criticised the comments, telling London's Evening Standard paper that Charles "has got a way of getting things absolutely wrong.

"It's an entirely Luddite attitude to simply reject them (GM crops) out of hand," he added.

Another Labour lawmaker, Ian Gibson, told the paper: "Prince Charles should stick to his royal role rather than spout(ing) off about something which he has clearly got wrong."

But the future king attracted support from environmental groups including Friends of the Earth.

"Prince Charles has hit the nail on the head about the damaging false solution that GM crops present," said its campaign director Mike Childs.

"GM crops will not solve the food crisis -- and forging ahead with an industrialised farming system will continue to fail people and the environment around the world."

The comments come amid rising concerns worldwide over rapidly rising food prices.

The World Bank estimates that food prices have almost doubled over the past three years, and its president Robert Zoellick has said two billion people are affected by the food crisis.

Venomous lionfish prowls fragile Caribbean waters

David McFadden, Associated Press Yahoo News 14 Aug 08;

A maroon-striped marauder with venomous spikes is rapidly multiplying in the Caribbean's warm waters, swallowing native species, stinging divers and generally wreaking havoc on an ecologically delicate region.

The red lionfish, a tropical native of the Indian and Pacific oceans that probably escaped from a Florida fish tank, is showing up everywhere — from the coasts of Cuba and Hispaniola to Little Cayman's pristine Bloody Bay Wall, one of the region's prime destinations for divers.

Wherever it appears, the adaptable predator corners fish and crustaceans up to half its size with its billowy fins and sucks them down in one violent gulp.

Research teams observed one lionfish eating 20 small fish in less than 30 minutes.

"This may very well become the most devastating marine invasion in history," said Mark Hixon, an Oregon State University marine ecology expert who compared lionfish to a plague of locusts. "There is probably no way to stop the invasion completely."

A white creature with maroon stripes, the red lionfish has the face of an alien and the ribbony look of something that survived a paper shredder — with poisonous spikes along its spine to ward off enemies.

The invasion is similar to that of other aquarium escapees such as walking catfish and caulerpa, a fast-growing form of algae known as "killer seaweed" for its ability to crowd out native plants. The catfish are now common in South Florida, where they threaten smaller fish in wetlands and fish farms.

In Africa, the Nile Perch rendered more than 200 fish species extinct when it was introduced into Lake Victoria. The World Conservation Union calls it one of the 100 worst alien species invasions.

"Those kinds of things happen repeatedly in fresh water," Hixon said. "But we've not seen such a large predatory invasion in the ocean before."

The lionfish so far has been concentrated in the Bahamas, where marine biologists are seeing it in every habitat: in shallow and deep reefs, off piers and beaches, and perhaps most worrisome, in mangrove thickets that are vital habitats for baby fish.

Some spots in the Bahamian archipelago between New Providence and the Berry Islands are reporting a tenfold increase in lionfish just during the last year.

Northern Caribbean islands have sounded the alarm, encouraging fishermen to capture lionfish and divers to report them for eradication.

The invasion would be "devastating" to fisheries and recreational diving if it reached Puerto Rico and the U.S. Virgin Islands, according to Eugenio Pineiro-Soler of the Caribbean Fishery Management Council.

"I think at the best they will have a huge impact on reef fish, and at the worst will result in the disappearance of most reef fish," said Bruce Purdy, a veteran dive operator who has helped the marine conservation group REEF with expeditions tracking the invasion.

Purdy said he has been stung several times while rounding up lionfish — once badly.

"It was so painful, it made me want to cut my own hand off," he said.

Researchers believe lionfish were introduced into the Atlantic in 1992, when Hurricane Andrew shattered a private aquarium and six of them spilled into Miami's Biscayne Bay, according to the National Oceanic and Atmospheric Administration.

Biologists think the fish released floating sacs of eggs that rode the Gulf Stream north along the U.S. coast, leading to colonization of deep reefs off North Carolina and Bermuda. Lionfish have even been spotted as far north as Rhode Island in summer months, NOAA said.

They are not aggressive toward humans, and their sting is not fatal. There are no estimates so far of tourists who have been stung. But marine officials say swimmers will be more at risk as the venomous species overtakes tropical waters along popular Caribbean beaches.

The slow-moving fish, which measures about 18 inches, is easy to snare, though lionfish swim too deep for divers to catch in nets — a common method of dealing with invasive species.

So researchers are scrambling to figure out what will eat the menacing beauties in their new Caribbean home, experimenting with predators such as sharks, moray eels — and even humans.

Adventurous eaters describe the taste of lionfish fillets as resembling halibut. But so far, they are a tough sell. Hungry sharks typically veer abruptly when researchers try to hand-feed them a lionfish.

"We have gotten (sharks) to successfully eat a lionfish, but it has been a lot of work. Most of our attempts with the moray eel have been unsuccessful," said Andy Dehart of the National Aquarium in Washington, who is working with REEF in the Bahamas.

One predator that will eat lionfish is grouper, which are rare in the lionfish's natural Southeast-Asian habitat. Scientists are pinning long-range hopes on the establishment of new ocean reserves to protect grouper and other lionfish predators from overfishing.

Hixon said there is some evidence that lionfish have not invaded reefs of the fully protected Exuma Cays Land and Sea Park, a 176-square-mile reserve southeast of Nassau. But unprotected locations in the vast archipelago are more vulnerable.

Containing the spread of the lionfish is an uphill fight. As lionfish colonize more territory in the Caribbean, they feed on grazing fish that keep seaweed from overwhelming coral reefs already buffeted by climate change, pollution and other environmental pressures.

Dehart said: "If we start losing these smaller reef fish as food to the lionfish ... we could be in a whirlwind for bad things coming to the reef ecosystem."

Associated Press Television News reporter Tracy Brown in Washington contributed to this report.

Will Deadly Pythons Spread Beyond Florida?

Robert Roy Britt, LiveScience.com Yahoo News 13 Aug 08;

Earlier this year, a U.S. Geological Survey report found that climate conditions favored the possible spread of Burmese pythons from Florida to as many as 32 states as the planet warms.

But a new study takes the opposite view: The voracious predators won't get out of the Everglades.

The foreign pythons were introduced to Florida by people who gave up their pets, scientists assume. A breeding population was discovered in the Everglades in 2003. Since then, populations have been found in many other locations, including other state parks, private land and even within municipalities. The powerful snakes, which squeeze life out of prey by constriction, can grow to 20 feet long and weigh more than 250 pounds.

Pythons have been known to devour dogs, consume cats and wrestle with alligators. One even tried, in a spectacularly unsuccessful event, to swallow a gator (the snake exploded).

What's at stake

Scientists fear the pythons will upset ecosystems.

"Wildlife managers are concerned that these snakes ... pose a danger to state- and federally listed threatened and endangered species as well as to humans," said Bob Reed, a USGS wildlife biologist at the Fort Collins Science Center in Colorado.

"Several endangered species have already been found in the snakes' stomachs," Reed said when the USGS report was released in February. "Pythons could have even more significant environmental and economic consequences if they were to spread from Florida to other states."

The USGS report was based, however, on just two climate factors: mean monthly rainfall and temperature.

"Although other factors such as type of food available and suitable shelter also play a role, Burmese pythons and other giant constrictor snakes have shown themselves to be highly adaptable to new environments," the USGS stated.

Opposite view

The new study, led by Frank Burbrink at the College of Staten Island/CUNY, used records on the distribution of pythons in their native range along with high-resolution global climate databases to predict the potential extent of the python's distribution in the United States and model the possible effects of global warming on the snakes.

"By using more complete climate data, in this case 19 variables measuring climatic extremes, averages and seasonal variation, we can make more accurate predictions of species distributions," said Alex Pyron, a graduate student at the City University of New York (CUNY). "Combining this climatic data with localities for the Burmese python allows us to create powerful models for predicting suitable habitat for the snakes."

The models, detailed Aug. 13 in the journal PLoS ONE, suggest that the pythons are restricted to the vicinity of the Everglades in extreme south Florida.

"The Burmese python is strongly limited to the small area of suitable environmental conditions in the United States it currently inhabits due to the ecological niche preferences of the snake," the researchers write. "Global warming is predicted to significantly reduce the area of suitable habitat worldwide, underscoring the potential negative effects of climate change for many species."

Reed, the USGS scientist, and his colleague Gordon Rodda, were both preparing to travel abroad this week and could not comment on the new study until having time to examine it thoroughly.

Plastics Suspect In Lobster Disease

Breakdown May Be Interfering With Molt
underwatertimes 13 Aug 08;

Woods Hole, Massachusetts -- The search for what causes a debilitating shell disease affecting lobsters from Long Island Sound to Maine has led one Marine Biological Laboratory (MBL) visiting scientist to suspect environmental alkyphenols, formed primarily by the breakdown of hard transparent plastics.

Preliminary evidence from the lab of Hans Laufer suggests that certain concentrations of alkyphenols may be interfering with the ability of lobsters to develop tough shells. Instead, the shells are weakened, leaving affected lobsters susceptible to the microbial invasions characteristic of the illness.

“Lobsters ‘know’ when their shell is damaged, and that’s probably the reason when they have shell disease, why they molt more quickly,” says Laufer, a visiting investigator at the MBL for over 20 years and professor emeritus of molecular and cell biology at the University of Connecticut. “But ultimately, they still come down with the disease. And we think the presence of alkyphenols contributes to that.”

Like any crustacean, lobsters shed their shells multiple times in one lifetime. After molting, the outer skin of the soft and exposed lobster will begin to harden. It is here that Laufer thinks the alkyphenols are doing their damage. At this point, a derivative of the amino acid tyrosine, whose function is to harden the developing shell, is incorporated. It is known that alkyphenols and tyrosine are similarly shaped and Laufer suspects that the toxin may be blocking tyrosine from its normal functions. He is at MBL this summer to measure the amount of competition between the two molecules. Alkyphenols are also known to act as endocrine disruptors.

Laufer discovered the presence of alkyphenols in lobsters serendipitously while investigating a tremendous lobster die off at Long Island Sound in 1999, when shell disease, first observed in the mid-1990s, was noted to be on the rise. Although an unusually hot summer, it was also the first time New York City sprayed mosquito populations to prevent the spread of West Nile virus. Laufer, who began his career as an insect endocrinologist, suspected the toxins from the sprayings may have contributed to the lobster die off. In 2001, while searching for the mosquito toxins in lobsters, he instead found alkyphenols.

“It’s a real problem,” Laufer says. “Plastics last a long time, but breakdown products last even longer. Perhaps shell disease is only the tip of the iceberg of a more basic problem of endocrine disrupting chemicals in marine environments.”

Dispute raises doubts over Brazil's Amazon dams

Stuart Grudgings, Reuters 13 Aug 08;

RIO DE JANEIRO (Reuters) - Environmentalists were dismayed this week when Brazil approved construction of one of two dams planned in the Amazon, but possible legal challenges and a dispute between construction groups threaten to delay both projects.

The Brazilian government sees the dams on the Madeira river, one of the Amazon river's biggest tributaries, as crucial to prevent energy shortages in its fast-growing economy over the next decade.

Beyond that, the $13 billion Jirau and Santo Antonio projects are seen as a key step in regional integration, creating a waterway that would cut transport costs for Brazil's agriculture exports and for farming areas in Bolivia and Peru.

Brazil's new environment minister, Carlos Minc, who has vowed to slash the time taken to license big projects, attached 40 provisions to Monday's approval of the installation of the Santo Antonio dam.

But environmentalists see the dams as a potential disaster that will flood up to 494,200 acres of forest, dramatically changing the ecosystem. They say the government has not provided enough safeguards.

"Minc is blowing a lot of smoke and pretending his agency is demanding a lot of rigorous measures," said Glenn Switkes, Latin America Program Director for International Rivers Network, a California-based group that protects rivers and the communities that depend on them.

"We're dealing with a principal tributary of the Amazon ... which has maybe the highest biodiversity of fish and among the highest biodiversity of birds in the world."

Environmentalists said the dams violate the Equator Principles on project finance that were signed by several banks potentially funding the projects, possibly opening the way for legal challenges.

CORPORATE SPAT

But while conservationists have so far failed to hold up the licensing process, the separate consortiums building the dams have launched into a quarrel that has the government worried about a legal battle and possible delays.

The government this week threatened to reopen the auctions or take over the projects through state-controlled generator Eletrobras if the business groups did not resolve their differences.

Victor Paranhos, head of the Enersus group that won the Jirau concession, accused the rival group led by construction giant Odebrecht on Monday of espionage after it sent a report about Enersus's building plans to the environment agency.

Odebrecht responded by starting legal proceedings on Tuesday that could lead to a defamation case against Paranhos.

The report by Odebrecht was critical of Enersus's plans to move the Jirau dam six miles downriver, something that could affect the other dam's generation capacity. The relocation has not yet been approved by the government.

"If an accord does not happen, the government could take the initiative to build the two works through Eletrobras," Energy Minister Edison Lobao told reporters on Tuesday.

French utility Suez, which leads the Jirau group, threatened last month to stop new investments in the Brazilian power sector if Odebrecht kept up its complaint, raising the prospect of wider fallout from the row.

Any delay in the projects is likely to raise investor concerns about their profitability, already fed by regulatory uncertainty and pressure from Brazil's government for low consumer tariffs.

The Jirau consortium agreed to market electricity from the 3,300 megawatt project at a 21.5 percent discount compared with the auction's base price.

Erasto Almeida, an energy analyst at Eurasia Group in New York, played down the risk of major delays, however.

"The Brazilian government really wants to get these projects done because of concerns about potential power shortages," he said. "My sense of this is that both companies will defend their interests and you might have legal action but there'll be some kind of agreement."

The Santo Antonio consortium also includes an investment fund set up by Spain's Santander and Portugal's Banif, and Furnas, a subsidiary of Eletrobras.

National Trust cuts plastic bags by 95 per cent with 5p charge

Aislinn Simpson, The Telegraph 13 Aug 08;

The National Trust has cut the number of plastic bags it hands out by 95 per cent after it started levying a five pence charge.

Its clampdown on the "plastic poison", blamed for harming wildlife and blighting the environment, follows similar successes at High Street stores and supermarkets across the country.

Thousands of customers have opted to either recycle old bags or invest in hessian and canvas, and the Government has warned of a mandatory charge for those retailers who do not get onboard the anti-waste bandwagon.

The National Trust implemented a plastic bag charge across its 220 shops and plant centres in England, Wales and Northern Ireland 100 days ago as part of a wider campaign to become more environmentally-friendly.

Starch alternatives to cellophane are used in the packaging of greetings cards and postcards, confectionary and sandwich boxes, and biodegradable bubble-wrap has been introduced for all packaging leaving its distribution centres.

The heritage and conservation organisation now claims to have saved more than 325,000 carrier bags from landfill, compared to the 1.25 million plastic bags it previously gave away each year.

By contrast, jute bags bearing the trust's oak leaf logo have jumped to 164,000 in the last four months, thanks to a £1.50 discount.

Stuart Richards, National Trust head of commercial operations, said it is now working with its suppliers to eradicate all unnecessary waste from its shops.

He said: "We're seeing people bringing their own bags from home but a lot of people have also invested in our jute bags, and we will be looking at extending this range.

"The feedback we've had from customers has been incredibly positive and such a dramatic drop in demand for plastic bags will help the National Trust cut its waste and reduce the amount of rubbish ending up in landfill sites."

Already the Trust has installed a range of other eco-measures across its stately homes and castles as part of a drive to make its properties more environmentally friendly.

Boilers fuelled by wood pellets were installed in the spectacular 17th century Sudbury Hall in Derbyshire where the BBC's adaptation of Pride and Prejudice was filmed.

This autumn, solar panels are to be built into the William and Mary-styled Hanbury Hall in Worcestershire to create an energy efficient method of heating the hot water system.

The campaign to wipe out plastic bags started in the small South Devon town of Modbury after local resident and camera woman Rebecca Hoskins went to the Pacific to film marine life for the BBC and saw first-hand the damage caused by waste plastic.

Her harrowing images of dolphins entangled in plastic and seals with their noses trapped in parcel tape roll had the impact of persuading Modbury's 43 traders to get rid of plastic bags altogether, making it the first town in the UK to be plastic bag free.

In February 2007, British retailers voluntarily committed to reduce the use of plastic bags, and Ikea, B& Q, Debenhams, Body Shop, Whole Foods Market and Oxfam went on to either ban them altogether or run trials on charges.

Of the big supermarkets, only Marks & Spencer has introduced a charge so far.

The result was an 80 per cent cut in bags handed out since the charge was introduced across M&S stores at the beginning of May.

The store estimated that 70 million fewer bags were handed out at its tills compared with the same period a year ago, and said it would donate the £200,000 it made on charges to Groundwork - which runs projects to create new parks and play areas.

Shops in Britain hand out almost 13 billion plastic bags every year, which are used for an average of just 20 minutes before being thrown away.

Most end up in landfill sites where they can take up to 1,000 years to rot away.

Scorching summer days to sizzle more by 2100: study

Alister Doyle, Reuters 13 Aug 08;

OSLO (Reuters) - Dangerously hot days are set to become more scorching by 2100 because of climate change with the U.S. Midwest or the Mediterranean region sizzling well above 40 degrees Celsius (104F), Dutch scientists said on Wednesday.

They said the likely jump in temperatures on the hottest summer days would far outpace the average of year-round global warming this century projected by the U.N. Climate Panel. Heatwaves can be a big threat to human health.

"The extremes warm faster than the averages," said Rob van Dorland, a spokesman for the Royal Netherlands Meteorological Institute which wrote the study with scientists at Utrecht University.

If world temperatures rose on average by perhaps 3 Celsius (5.4F) by 2100, the temperature on the most sweltering day of the year could leap by up to 8 Celsius (14.4F), he said.

Computer projections indicated that temperatures would hit baking peaks above 50 Celsius (122.00F) in parts of Australia, India, the Middle East, North Africa, the Sahel and equatorial and subtropical South America by the 2100.

"In much of the United States, in southern Europe and in the populated regions of Australia, values far exceeding 40 Celsius are reached," the scientists wrote in the journal of the American Geophysical Union.

"Such temperatures, if lasting for some days, are life-threatening and receive relatively little attention in the climate change debate," they wrote.

A heatwave in Europe in 2003 killed 15,000 people in France and almost 3,000 in Italy, mostly elderly people who are often most at risk. The Dutch report did not examine likely impacts on public health, or food production.

The U.N. Climate Panel projects that rising temperatures will cause more heatwaves, droughts, floods, contribute to spread disease and melt glaciers, pushing up world sea levels.

Dorland said it was unclear why extreme temperatures would rise so fast -- a theory was that warmer soils dry out, reducing the amount of heat they can absorb from the sun. "If the soil is drier, then solar energy goes more to heating the air," he said.

And a shift in wind patterns could also bring more sweltering conditions, for instance around the Mediterranean. "In the Mediterranean area we expect more southeasterly winds in summer...that means more sun and less cloud," he said.
