Debate rages over plastic bottle chemical's safety

Will Dunham, Yahoo News 18 Apr 08;

Canada is moving to get rid of products with a chemical common in plastic baby bottles, the United States is expressing concern over its safety and some retailers are planning to stop selling these items.

But whether the chemical bisphenol A poses genuine health risks in people remains a matter of debate, with industry groups defending its safety and environmental activists saying studies involving animals show otherwise.

Bisphenol A, or BPA, is used to make polycarbonate plastic, a clear shatter-resistant material in products ranging from plastic baby and water bottles to sports safety equipment and medical devices.

It also is used to make durable epoxy resins used as the coating in most food and beverage cans.

People can eat or drink the chemical when it leaches out of the plastic into liquid such as baby formula, water or food inside the container.

"At this point, the writing is on the wall for bisphenol A. Major retailers and governments all across the country and the world are now recognizing that this chemical is extremely toxic at very low levels of exposure," Michael Schade of the U.S. environmental group Center for Health, Environment and Justice said in a telephone interview.

Critics of BPA said more than 150 scientific studies involving laboratory rodents show BPA to be harmful at even low levels. But some experts are not convinced.

"For me, the big question is: what levels of exposures are we getting and are those levels of exposure sufficient to cause harm?" Carl Winter, director of the Food Safety Program at the University of California-Davis, said in a telephone interview.

"There still does not exist strong evidence supporting significant impacts on human health for bisphenol A," he said.

"NEGLIGIBLE RISK"

Steven Hentges of the American Chemistry Council downplayed the animal studies, saying they "have not been corroborated between labs and the entire data set is not coherent."

He added: "We do believe that bisphenol A poses negligible risk to human health."

On Tuesday the National Toxicology Program, part of the U.S. government's National Institutes of Health, issued a draft report expressing concern that BPA could cause neural and behavioral problems in fetuses, infants and children.

Relying on the results of animal studies, it expressed concern about possible links between BPA exposure and early puberty and prostate and breast cancer.

Dr. Anila Jacob of the activist Environmental Working Group said using rodent studies to assess toxicity is a well-established practice given that scientists cannot expose humans to possible toxins in research for ethical reasons.

Canadian Health Minister Tony Clement said on Friday his country intends to become the first to ban the import and sale of some types of plastic baby bottles because they contain BPA. He expressed concern that overexposure at an early age could cause later behavioral and neurological symptoms.

Wal-Mart, the world's largest retailer, announced on Thursday it plans to offer more BPA-free products and intends to stop selling baby bottles made with BPA early next year.

Rochester, New York-based bottle maker Nalgene said on Friday it will phase out production of bottles made with BPA. Nalgene is owned by Thermo Fisher Scientific Inc.

U.S. states including California, Maryland, Minnesota and Michigan are considering bills to ban or restrict bisphenol A in children's products.

In Washington, Democratic Reps. John Dingell and Bart Stupak have been investigating BPA in products intended for use by infants and children. They are calling on the Food and Drug Administration to reconsider its view that it is safe.

Climate change: Progress at polluters' talks, but obstacles ahead

Richard Ingham and Marlowe Hood, Yahoo News 18 Apr 08;

Talks among major carbon emitters aimed at speeding negotiations towards a new pact on climate change ended Friday after making some headway but failing to remove roadblocks ahead of a summit in July.

"We achieved a consensus on the need for long-term and medium-term goals for reducing greenhouse-house gases... but we have not quantified targets at this stage and we regret this," said France's secretary of state for European affairs, Jean-Pierre Jouyet.

The two-day talks in Paris gathered ministers from Australia, Brazil, Britain, Canada, China, France, Germany, India, Indonesia, Italy, Japan, South Korea, Mexico, Russia, South Africa and the United States.

The 16 economies account for around four-fifths of global output of greenhouse gases -- the carbon pollution, stemming mainly from fossil fuels, that traps heat from the Sun and is damaging Earth's climate system.

Launched by US President George W. Bush last September, the so-called Major Economies Meetings (MEMs) aim at fast-tracking negotiations towards a new UN pact on climate change by the end of 2009.

The process also looks at how to enlist smart technology and energy-intensive industries to cut greenhouse-gas emissions.

MEM leaders are to meet on the sidelines of the Group of Eight (G8) summit in Toyako, Japan on July 7-9, and issue a declaration reflecting a "shared common vision," said Jouyet.

But there was discord over whether this horizon-scanning document should set a timetable and cap for global emissions.

"As a European, we would like to see the most quantified objectives possible, both in the medium and long term. There is a divergence with our American partners on this subject," said Jouyet.

"Discussions are continuing but there are no major breakthroughs," South African Environment Minister Marthinus van Schalkwyk told AFP.

Developing countries opposed setting any long-term goal in Toyako that was too nebulous and lacked specific pledges from the United States on emissions, he said.

As a result, the summit declaration could be limited to a vaguer statement expressing goodwill and areas where progress can be made, he said.

Two more MEM meetings will be held before the summit, one in May the other in June, to try to hammer out the declaration.

The Paris meeting was given fresh reminders that huge financial resources must be mustered to tackle climate change.

A South African assessment found that between 30 and 60 billion dollars was needed annually as of now to help poor countries cope with the impact of climate change. And 200 billion dollars was needed annually for reducing emissions.

Mexico floated an idea for a new "Multinational Climate Change Fund" gathering at least 10 billion dollars per year that would help promote the transfer of clean technologies to developing nations.

On the meeting's eve, Bush unveiled a new blueprint, based on incentives rather than on mandatory caps, that called for US emissions to peak by 2025. And he urged big developing countries to agree to concessions in a future deal.

This proposal by the world's No. 1 polluter was widely attacked as too little, too late.

Some blasted it as a step backwards to before last December's breakthrough agreement in Bali that launched the two-year UN negotiation process.

French President Nicolas Sarkozy told the meeting on Friday that global warming was becoming a driver of hunger, unrest and conflict.

He cited the nearly five-year-old war in Darfur, where more than 200,000 people have died, as an example of how water scarcity and rivalry for farmland had helped spark bloodshed.

"In Darfur, we see this explosive mixture from the impact of climate change, which prompts emigration by increasingly impoverished people, which then has consequences in war," said Sarkozy.

"If we keep going down this path, climate change will encourage the immigration of people with nothing towards areas where the population do have something, and the Darfur crisis will be only one crisis among dozens of others."

Climate talks advance, but split on 2050 goals
Alister Doyle, Reuters 18 Apr 08;

PARIS (Reuters) - Major economies made progress in defining the building blocks of a new U.N. deal to fight climate change on Friday but ended split over whether to set a goal of halving world greenhouse gas emissions by 2050.

The U.S.-led meeting of 17 nations accounting for 80 percent of global greenhouse gas emissions, ended with common ground on sharing clean technologies, financing and possible sectoral emissions goals for industries such as steel or cement.

"In my view we have made significant progress," Daniel Price, U.S. Deputy National Security Advisor for International Economic Affairs, told reporters after two days of talks including China, Russia, India and the European Union.

The talks shifted to a more positive mood after opening with criticisms of President George W. Bush for setting only a 2025 ceiling for halting a rise in U.S. emissions when other rich nations have set 1990 caps under the U.N.'s Kyoto Protocol.

"People are understanding each other better on a number of topics," said Yvo de Boer, head of the U.N. Climate Change Secretariat, who called progress "substantive" in work on a new U.N. climate treaty due to be agreed by the end of 2009.

Deep divisions remained about whether to set a goal of halving global emissions by 2050, favored by the European Union, Japan and Canada as part of a fight against warming that may bring more floods, droughts, heatwaves and rising seas.

Developing nations said they would not sign up to such a goal at a planned summit of leaders of the 17 major economies on July 9 in Japan unless Washington did far more to curb emissions, mainly from burning fossil fuels.

"I would be very surprised if there are specific numbers by July because the rest of the world is waiting...for that strong enough signal from the U.S.," South African Environment Minister Marthinus van Schalkwyk said.

JULY SUMMIT

Trying to break deadlock, delegates agreed to have two more meetings of experts to prepare for the July meeting, to be held on the sidelines of a July 7-9 Group of Eight summit.

The United States said it was still "seriously considering" whether to adopt a goal of halving world emissions by 2050 and that new technologies such as clean coal or new biofuels could cut emissions in coming decades.

Japan's Koji Tsuruoka, a senior foreign ministry official, said Tokyo would prefer all 17 nations to agree a 50 percent cut by 2050 rather than just the G8. Developing nations also want more aid and technology before committing themselves to curbs.

France said that South Africa presented studies suggesting it would cost the world up to $200 billion a year to curb greenhouse gases and between $30 and $60 billion a year to adapt to effects such as droughts or rising seas.

Many delegates at the meeting, the third since September in a series launched by Bush amid skepticism abroad about his environmental record, said they were starting to look to the next U.S. president who will take office in January 2009.

Republican presidential candidate John McCain and Democratic hopefuls Barack Obama and Hillary Clinton all favor tougher goals than Bush for curbing greenhouse gases.

Industrialized nations apart from the United States have agreed to consider cuts in emissions of 25 to 40 percent below 1990 levels by 2020 as part of a new U.N. climate treaty to succeed the existing Kyoto Protocol.

U.S. and EU greenhouse gas emissions fell in 2006, according to data submitted to the United Nations, bucking a rising global trend. U.S. emissions fell by 1.3 percent and EU emissions by 0.3 percent.

The Paris talks group the United States, France, Germany, Italy, Britain, Japan, China, Canada, India, Brazil, South Korea, Mexico, Russia, Australia, Indonesia and South Africa. The European Commission, current EU president Slovenia and the United Nations were also attending.

18 US states commit to take action on climate change

John Christoffersen, Associated Press Yahoo News 19 Apr 08;

California Gov. Arnold Schwarzenegger predicted Friday that an international deadlock over how to deal with global warming will end once President Bush leaves office, while a leading expert warned of dire consequences if urgent action is not taken.

Schwarzenegger spoke at a conference at Yale University in which 18 states pledged to take action on climate change. He noted a dispute over whether the U.S. should commit to reducing its greenhouse gas emissions before China and India do the same.

"But I think the deadlock is about to be broken," said Schwarzenegger, a Republican like Bush.

Schwarzenegger said all three president candidates would be great for the environment and predicted progress after one is inaugurated.

Schwarzenegger has been at odds with the Bush administration over a 2002 California law to reduce greenhouse gas emissions. The U.S. Environmental Protection Agency blocked the law from taking effect in California and 16 other states, saying global warming is not unique to the state and that emission goals should be set nationally.

Bush called for a halt Wednesday in the growth of greenhouse gases by 2025, acknowledging the need to head off serious climate change. The plan came under fire immediately from environmentalists and congressional Democrats who favor mandatory emission cuts, a position also held by all three presidential contenders.

Bush for the first time set a specific target date for U.S. climate pollution reductions and said he was ready to commit to a binding international agreement on long-term reductions as long as other countries such as China do the same.

Dr. R. K. Pachauri, chairman of the Nobel Prize-winning United Nations' Intergovernmental Panel on Climate Change, warned that without action to curb global warming agricultural yields would fall and flooding and heat waves would become more intense. Some species could become extinct, he said.

Pachauri said measures to curb warming are not expensive.

"The myth that there will be a loss of jobs and economic output needs to be exploded," Pachauri declared.

Pachauri praised the efforts of governors to deal with the issue.

"But there is a need for the country as a whole to move forward," Pachauri said.

The governors of Connecticut, California, Kansas and New Jersey were at Yale on Friday along with two Canadian premiers to review state programs and develop a strategy to combat global climate change.

"If we can move the states forward toward serious action it is a very substantial commitment and a very significant step toward the start of a thoughtful and serious response to address the problem of climate change," said Daniel Esty, director of the Yale Center for Environmental Law and Policy.

Esty said the 18 states that signed a declaration committing themselves to action together produce as much emissions as Europe's four biggest economies.

Among other things, the declaration says the states recommit themselves to the effort to stop global warming and call on congressional leaders and presidential candidates to work with them to establish a comprehensive national climate policy.

"Rewarding and encouraging meaningful and mandatory federal and state climate action is the key to success," the declaration states.

It also pledges to reach out to the presidential candidates to shape the first 100 days of the next administration.

The states signing the declaration are: Arizona, California, Colorado, Connecticut, Delaware, Florida, Illinois, Kansas, Maine, Maryland, Massachusetts, Michigan, New Jersey, New Mexico, New York, Oregon, Virginia and Washington.

EU and U.S. greenhouse gas emissions fell in 2006

Reuters 18 Apr 08;

LONDON (Reuters) - U.S. and European Union emissions of greenhouse gases fell in 2006, data published this month on a U.N. Web site show, offering some positive news amid a global picture of rising emissions.

President George W. Bush said this week he wanted U.S. emissions to peak by 2025.

Industrialized countries usually pare their energy use per unit of output year on year, as businesses try to save on costs through efficiency measures, thereby curbing carbon emissions from burning fossil fuels.

But overall emissions can still rise because of economic growth and other factors including the weather.

The EU data were dated April 15 and are not officially published until Monday. The U.S. report was dated April 10.

The data showed that in 2006 U.S. greenhouse gas emissions fell by 1.3 percent and EU emissions by 0.3 percent. In 2005 U.S. emissions rose by 0.6 percent and EU emissions fell by 0.4 percent.

Globally, greenhouse gas emissions are rising at about 3 percent a year, especially because rapid economic growth in China and India is fuelling massive demand for energy from high carbon-emitting coal-fired power plants.

161 Singapore schools receive Green Audit Awards

Channel NewsAsia 18 Apr 08;

SINGAPORE : Christ Church Secondary School has emerged as the top winner at this year's Green Audit Awards ceremony.

The school's environmentally-friendly projects have attracted quite a bit of attention.

For example, the students have come up with soaps that are made from used cooking oil, from their school canteen. The soaps are also scented with herbal oils from the school garden.

The students also came up with scented candles that can act as a mosquito-repellent.

Student Ho Jian Xiong said, "During the dengue period, when the dengue cases were very high, we actually added citronella to the aromatic candles. We publicised it during the Lantern Festival period, and during that time, when old folks were bringing their grandchildren out to light up their lanterns, they saw our candles. Grandparents are very conscientious of their family's health, so (the candles) were very popular back at that period."

Another project is a clock that is powered by not batteries but a combination of salt solution and potato skins.

Such creative and green solutions have led Christ Church Secondary to win the top award, three years in a row.

On Friday, it received the Sustained Achievement Award, which also came with a cash prize of S$100.

A total of 161 primary and secondary schools received their Green Audit Awards, which is given out by the Singapore Environment Council, to recognise schools' efforts to reduce and recycle resources.

The Green Audit Award programme was established in 2000.

It calculates the schools' usage of water and electricity, as well as the wastage generated by school facilities, such as canteens, offices, classrooms and gardens. - CNA/ms

More Singapore motorists opt for bi-fuel cars to cut costs, save environment

Channel NewsAsia 18 Apr 08;

SINGAPORE: More motorists are converting their cars to run on two types of fuel - compressed natural gas (CNG) and regular petrol.

In Singapore, CNG conversion workshop C. Melchers-Galileo has taken the lead in converting regular cars to bi-fuel cars. It has seen a 50 per cent increase in demand since last November.

Gilbert von der Aue, sales manager at C. Melchers, said: "We started last November in this workshop. Ever since then, we've done 400 cars. We convert 80 cars per month currently, and from next month onwards we'll be doing 120 cars. We have a waiting list of about six months."

The initial outlay cost to convert a regular car is almost S$4,000. But in the long term, it will cost less to own a bi-fuel car.

"CNG is so much cheaper than petrol. It's about a third the cost of petrol. So I would save about 70 per cent if I drive on CNG instead of driving on petrol. On top of that, CNG runs cleaner so I don't have to do an oil change as often as I would if I had a petrol or diesel engine."

"It makes sense financially. You just have to pay one time but you save the environment. That's the whole reason for it," said a member of the public.

"If it's safe, if it's more economical, why not?" said another.

C. Melchers said it is targeting middle- to lower-income Singaporeans because they are the ones who will benefit the most from cost savings.

But when it comes to cars, cost is definitely not the only consideration.

"For me, I prefer performance cars. It's great to save the world, but I didn't get this car for nothing. I won't be converting soon," said a member of the public who drives a sports car.

But more may change their minds as petrol prices continue to rise. Currently, a litre of 95-octane unleaded petrol costs about S$2.08, but a kilogramme of CNG only costs between S$1.18 and S$1.24.

However, not everyone is swayed, because right now there are only two stations accessible to the public on mainland Singapore - one at Jalan Buroh in Jurong and the other at Mandai Road in the north.

Three more stations will be ready by the end of this year - at Jalan Bukit Merah, Bedok and Serangoon North. - CNA/ac

Attenborough ends nature TV cycle, fears for future

Mike Collett-White, Reuters 18 Apr 08;

LONDON (Reuters) - David Attenborough has done more than just about anyone to teach us about our planet.

As he marks the end of his sweeping natural history television series, seen by hundreds of millions of people over 30 years, the British broadcaster is fearful of what the future holds for the Earth and its inhabitants.

"We've come to an end of a particular genre, a particular type of making programs," Attenborough told Reuters, referring to the series that began with "Life on Earth" in 1979 and ended earlier this year with "Life In Cold Blood".

"You could say that this is a survey of how the world looked and how it may not look the same in 50 years' time."

The series took Attenborough around the world and included memorable scenes like his encounter with mountain gorillas when he whispered to the camera as the animals surrounded him.

It also featured startling images from wildlife that were the result of pioneering camerawork and painstaking research. "Life on Earth" alone was watched by an estimated 500 million people worldwide, according to the BBC.

Attenborough, who began his career with the British Broadcasting Corporation in 1952, said the impact of global warming over the last 50 years meant that making the same programs today would be difficult, if not impossible.

"There are some things in that series that would be very difficult to film again, they are much more difficult to find."

He added that he did not know of a single "major" vertebrate species that had become extinct during his career, but serious risks to plants, animals and humans lay ahead.

"The plain, simple, overwhelming fact of the matter is that since I started making programs, there are three times as many people on the Earth," he said.

"It is inevitable that you are going to make huge inroads into what was wild nature and that process is going on. It's going to get worse before it gets better."

"DEEPLY DEPRESSING"

Attenborough, younger brother of film director Richard, agreed with some scientists' prediction that it was too late to reverse the impact of climate change.

"Whatever we do now the world is going to change. The question is can we slow down those changes or reduce them? One clutches at straws to try and find something in this bleak picture which is not deeply depressing."

Among those straws are the fact that governments are taking the issue seriously and popular awareness of the dangers climate change poses to the environment has spread.

"People recognize that the only conceivable way in which you'll save the life in the sea and the climate in the air is by international agreement," he explained. "It's damned difficult."

His comments came as 17 countries responsible for 80 percent of greenhouse gas emissions met in Paris to find common ground on how to thrash out a new treaty to fight climate change.

The publicly funded BBC is releasing a DVD box set of four of Attenborough's documentary series to coincide with Earth Day on April 22. The environmental awareness campaign organizes events around the world each year, and dates back to 1970.

Attenborough welcomed popular movements promoting a sustainable environment, saying young people were what counted.

"It's all very well for me crying doom and gloom, but the people who are going to suffer are my grandchildren, and my grandchildren are certainly exorcised about. They are outraged at what's happening to the wild places of the Earth."

At 81, the broadcaster said he was not about to retire, although his globetrotting filmmaking days may be over.

"Next February is the 200th anniversary of the birth of Charles Darwin and I am making a program about evolution.

"(There will not be) a lot (of travel) because a great deal of the stuff one wants to show I've filmed. Ever mindful of the license holder's money and my carbon footprint, I'm not getting on to a lot of airplanes."

Freshening of deep Antarctic waters worries experts

David Fogarty, Reuters 18 Apr 08;

SINGAPORE (Reuters) - Scientists studying the icy depths of the sea around Antarctica have detected changes in salinity that could have profound effects on the world's climate and ocean currents.

The scientists returned to the southern Australian city of Hobart on Thursday after a one-month voyage studying the Southern Ocean to see how it is changing and what those changes might mean for global climate patterns.

Voyage leader Steve Rintoul said his team found that salty, dense water that sinks near the edge of Antarctica to the bottom of the ocean about 5 km (3 miles) down was becoming fresher and more buoyant.

So-called Antarctic bottom water helps power the great ocean conveyor belt, a system of currents spanning the Southern, Pacific, Indian and Atlantic Oceans that shifts heat around the globe.

"The main reason we're paying attention to this is because it is one of the switches in the climate system and we need to know if we are about to flip that switch or not," said Rintoul of Australia's government-backed research arm the CSIRO.

"If that freshening trend continues for long enough, eventually the water near Antarctica would be too light, too buoyant to sink and that limb of the global-scale circulation would shut down," he said on Friday.

Cold, salty water also sinks to the depths in the far north Atlantic Ocean near Greenland and, together with the vast amount of water that sinks off Antarctica, this drives the ocean conveyor belt.

This system brings warm water into the far north Atlantic, making Europe warmer than it would otherwise be, and also drives the large flow of upper ocean water from the tropical Pacific to the Indian Ocean through the Indonesia Archipelago.

If these currents were to slow or stop, the world's climate would eventually be thrown into chaos.

"We don't see any evidence yet that the amount of bottom water that's sinking has declined. But by becoming fresher and less dense it's moving in the direction of an ultimate shutdown."

Rintoul said results of the bottom water samples in the Ross Sea directly south of New Zealand and off Antarctica's Adelie Land further to the west, were a crucial finding.

"We didn't know that before we left but it's now clear that both of those regions are becoming fresher for some reason."

GLOBAL WARMING TO BLAME?

During the voyage, scientists from Australia, Britain, France and the United States measured salinity, carbon dioxide and iron concentrations as well as currents between Antarctica and Australia.

Rintoul said his team are studying if faster melting of icesheets or sea ice is the source of the fresher water but he said it was too early to tell if global warming was to blame.

Over the coming months, his team will study oxygen isotopes collected from water samples.

"Oxygen isotopes act as a tracer of ice melt and that information should help pin down exactly what the cause of the freshening is in the deep ocean," said Rintoul, of the Antarctic Climate and Ecosystems Cooperative Research Centre.

"The leading hypothesis at the moment for why it's freshening is that the floating ice around Antarctica is melting more rapidly than in the past."

He pointed to studies showing winds around Antarctica changing because of global warming and the ozone hole.

"The most likely scenario is that those changes in winds have changed the circulation of the ocean, in particular caused more upwelling of relatively warm water from below and that could have caused the increased melting of ice around Antarctica," he said.

"The next challenge over the coming months and year will be to see just how well we can this pin down."

A species threatened by avarice of man: the white rhino

Michael McCarthy, The Independent 18 Apr 08;

It has been coming for a long time – the first extinction of what zoologists refer to, ironically, as the Charismatic Megafauna, the group of big wild animals that have always captured our imagination, from lions and tigers to elephants and giraffes.

And if it cannot be stopped by the revolutionary technique that we report on today, the disappearance of the northern white rhino will mark a milestone in man's unhappy impact on the natural world.

It will show that, despite the most tremendous conservation efforts, some of the great beasts of the Earth simply cannot be saved.

The moment may nearly be here. The northern white rhino is a creature that is now as close to the brink of extinction as it is possible to get without toppling over, with perhaps as few as three animals left in the wild, and a tiny population of less than a dozen held in zoos across the US and Eastern Europe, which is probably non-viable from a breeding point of view.

The wild animals have the misfortune to exist in a single site, the Garamba National Park, which lies in one of the most war-torn countries in the world, the Democratic Republic of the Congo (DRC), near the border of another such ravaged land, Sudan.

The collapse of civil order in so much of Africa in recent decades has been the bane of this species, which, besides the DRC, once ranged over north-west Uganda, southern Chad, south-western Sudan and the eastern side of the Central African Republic.

As late as the early Sixties, there were thought to be about 2,000 northern white rhinos left but, during the next 20 years, poaching started to take a toll and eventually devastated the population until, by 1984, the numbers were down to 15. The poaching was driven by a specific demand – for rhino horn, which was used to make dagger handles in Yemen.

International efforts were then focused on saving the animal and, under a strictly monitored protection regime, the numbers climbed back to about 30 by 1993. But then the Rwandan genocide spilled over into civil war in the DRC, and preserving wildlife became both a much lower priority for the Congolese government and a much more dangerous affair for park wardens.

Several of the guards at Garamba have been killed in clashes with poachers, and the enforcement regime in this desperately poor country has simply not been able to prevent the rhino's slide towards extinction.

Scientists look for link between damage to the Ningaloo reef and climate change

Scientists look for link between coral bleaching and global warming
ABC News 18 Apr 08;

Marine Scientists are trying to determine whether damage to the Ningaloo reef is linked to climate change.

Researchers believe 1.5 square kilometres of reef in Coral Bay was bleached during spawning several weeks ago.

A number of fish and clams were also killed.

Bleaching occurs when wind and ocean currents fail to disperse spawn causing a lack of oxygen in the water.

Marine Scientist Dr Chris Simpson says climate change could be causing the problem.

"It does look like it's becoming more frequent and that could possibly be related to changes in the climate and things like that where the winds aren't as strong and things like that but of course that's all very speculative at this point in time," he said.

A more detailed study of Ningaloo planned for next year may now be brought forward to assess the damage.

Asia Dive Expo sets standards in conservation awareness

BYM news 17 Apr 08;

Asia Dive Expo 2008 (ADEX) opens today at Suntec Singapore with a bold new agenda for the regional dive community – “Save The Seas, Be A Diver”. ADEX this year focus on the need for greater awareness of marine conservation as it runs from 18-20 April 2008 at Halls 602 and 603. ADEX 2008 is opened today by Mr. Francis Lee, Chairman of Marine Roundtable Singapore Chapter.

This year has particular significance for the marine conservation movement. 2008 has been designated the International Year of the Reef (IYOR), a worldwide initiative to raise awareness of the value and importance of coral reefs. Singapore will be joining 50 countries around the world to improve understanding of the threats to these endangered reefs.

ADEX 2008 will welcome the presence and input of top international marine conservationists such as Richard Leck from the World Wildlife Fund’s Coral Triangle Program, Christine Ward-Paige from Global Shark Awareness and Julian Hyde from Reef Check.

Said Herman Ho, Managing Director of ADEX organiser TMX Show Productions Pte Ltd, "The main attraction of ADEX this year is EcoVillage @ ADEX 2008, where a combination of exciting activities including seminars, film fests, photography competitions, educational tours, ADEX auctions and ADEX merchandise.

“The activities in EcoVillage @ ADEX are designed to foster a sense of environmentalism as a way of life amongst both adults and students. All proceeds from ADEX merchandise will be donated to a major marine conservation cause, the International Year of the Reef 2008.” Herman added.

ADEX visitors can learn all about regional and even local marine conservation initiatives such as the Coral Nursery, a project launched to preserve and proliferate natural corals by The National Parks Board (NParks) and its partners Keppel Group, National University of Singapore and National Environment Agency.

Additionally, ADEX has lined up an exciting program of screenings, presentations, talks, seminars and activities which will educate and entertain on an array of dive-related subjects. Many of the films being screened earned plaudits at the Celebrate the Sea Festival, which awards the best of the dive industry’s vibrant underwater film-makers.

"In line with ADEX’s conservation theme this year, many of our presentations and screenings reflect an environmental consciousness and an awareness of the delicate nature of our planet’s marine eco-systems,” said Mr. Ho.

Aside from the educational aspects, as always at ADEX there will also be a generous number of prizes, giveaways, dollar deals and fun activities like the Scuba Tryouts where potential divers can learn the basics in a safe environment.

ADEX 2008 sees the return of regular major name exhibitors including Bauer Compressors Asia Pte Ltd., Beuchat International SA, and Coltri Sub Asia Pacific. They are joined this year by new names like Dive Junkie, EKO Asia Pacific, Innerspace Dive Explorers and OPTIMUS.

Amongst those destinations touting their pristine azure waters will be Christmas Island Tourism Association, Philippines Tourism Board, Santika – Thalassa Dive Resort, Minahasa Lagoon, Redang Kalong Resort and Walea Dive Resort.

Supporting ADEX again this year are leading dive and conservation related associations and organisations including the Diving Equipment & Marketing Association (DEMA), the British Sub Aqua Club (BSAC), Divers Alert Network (DAN), the International Association of Nitrox and Technical Divers (IANTD), Scuba Schools International (SSI), the Singapore Underwater Federation (SUF) and the Singapore Environment Council (SEC).
