Marine Debris Will Likely Worsen in the 21st Century

Goal of Zero Waste Discharge Should Be Adopted
EurekAlert 19 Sep 08;

Current measures to prevent and reduce marine debris are inadequate, and the problem will likely worsen, says a new congressionally mandated report from the National Research Council.

The United States and the international maritime community should adopt a goal of "zero discharge" of waste into the marine environment, and a system to assess the effectiveness of existing and future marine debris prevention and reduction actions should be implemented.

In addition, better leadership, coordination, and integration of mandates and resources are needed, as responsibilities for preventing and mitigating marine debris are scattered across federal organizations and management regimes.

"The committee found that despite all the regulations and limitations over the last 20 years, there are still large quantities of waste and litter in the oceans," said Keith Criddle, chair of the committee that wrote the report and the Ted Stevens Distinguished Professor of Marine Policy at the Juneau Center for Fisheries and Ocean Science, University of Alaska, Fairbanks. "We concluded that the United States must take the lead and coordinate with other coastal countries, as well as with local and state governments, to better manage marine debris and try to achieve zero discharge."

A National Research Council committee was convened at the request of Congress to assess the effectiveness of international and national measures to prevent and reduce marine debris and its impact. Marine debris, man-made materials that intentionally or accidentally enter and pollute the ocean, can cause significant harm. For instance, birds, fish, and marine mammals ingest debris, especially plastics, which can lead to digestive problems and uptake of toxic compounds. Animals can also suffer injuries or die after becoming entangled in fishing-related debris such as plastic net fragments, rope, and packing straps. Marine debris also poses a health and safety hazard to beachgoers and divers, and could impact coastal recreation and tourism revenue. While marine debris comes from sources both on land and at sea, the committee focused on debris discharged at sea for the purposes of this report.

Although Congress previously called for federal interagency coordination to address the marine debris problem, leadership and governance remain inefficient and current mitigation efforts are episodic and crisis driven, the committee found. A national framework to identify priorities for dealing with marine debris and its removal efforts should be established. Additionally, Congress should designate a lead agency to expand programs to comprehensively address the problem, including land-based marine litter, derelict fishing gear, shipborne waste, and abandoned vessels.

Under the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex V, which entered into force in 1988, many discharges from ships are permissible at sea. The committee said this approach does not encourage innovation or measures to minimize waste. It suggested that MARPOL Annex V be amended to include a prohibition on discharge of garbage at sea, allowing for limited exceptions based on specific vessel-operation scenarios. In order to discourage waste disposal at sea, ships also need to have access to adequate shoreside waste reception facilities for garbage and should be provided incentives, such as low disposal fees to use them, the report adds.

Nevertheless, some ships have already adopted zero or minimal discharge practices. The U.S. Coast Guard (USCG) and U.S. Environmental Protection Agency should disseminate best management practices for how vessels can attain zero discharge, source reduction, and waste minimization, the committee urged. EPA should also take the lead to work with academia, industry, and nongovernmental organizations to develop industry standards and guidelines for source reduction, reuse, and recycling for solid wastes that are generated during ship operations.

The committee was specifically asked to address the challenges surrounding derelict fishing gear. While regulated under MARPOL Annex V and domestic implementing laws, it is a persistent problem because of accidental losses and legal loopholes. Also, current regulations do not include accountability measures for commercial and recreational fishing vessels for loss of their fishing gear, offering few incentives to take responsibility for cleanup.

Effective marking of fishing gear is critical for identifying the sources or fisheries that may have deployed the gear, and NOAA should develop marking protocols, the report claims. Fishery management organizations should also adopt a "no fault" policy regarding the documentation and recovery of lost fishing gear. Under this policy, local fishermen, state officials, and the public should develop cost-effective derelict fishing gear removal and disposal programs, and fishermen participating in removal efforts could receive financial credit or be exempted from landfill fees.

Moreover, the high costs and difficulty in providing adequate reception facilities, particularly in remote areas, discourages proper disposal of used fishing gear and can also be a disincentive to retrieval. Therefore, EPA, NOAA, and the U.S. Army Corps of Engineers should help fishing communities explore alternative strategies and technologies for management, disposal, and recycling of used and recovered gear.

Within the issue of derelict fishing gear, the committee also addressed the growing concern about a specific type of gear known as fish aggregating devices, which are man-made floating objects designed to simulate natural debris and attract fish. These devices pose a threat as they are allowed to float freely and are often made of waste fishing net. The committee concluded that abandoned fish aggregating devices become derelict fishing gear when the captain of the vessel does not retrieve them. Under MARPOL Annex V, this should be considered an illegal disposal if the devices contain synthetic ropes, webbing, or other plastics. NOAA should modify the federal regulations to clarify the circumstances under which abandoned fish aggregating devices become illegal discharge. The committee also indicated that international and domestic fisheries organizations should do more to regulate these devices and prevent them from becoming debris.

AVA stops import & sale of milk and dairy products from China

Channel NewsAsia 19 Sep 08;

SINGAPORE - The Agri-Food and Veterinary Authority (AVA) has suspended the import and sale of all milk and dairy products from China with immediate effect, after tests found melamine contamination in two brands of China-made milk products.

Two days ago, AVA issued an advisory about the recall of Yili brand "Choice Dairy Fruit Bar Yogurt Flavoured Ice Confection" based on Hong Kong's findings of melamine contamination in such products.

Subsequently, AVA took samples of the product for testing and found two samples to be contaminated with melamine. All stocks of the affected product have been removed from market shelves since 17 September and will be destroyed, said an AVA statement on Friday.

"Our tests also found that the "Dutch Lady" brand of strawberry flavoured milk manufactured in China to be contaminated with melamine. These products have also been recalled and will be destroyed. Other "Dutch Lady" brand milk products which are not manufactured in China are unaffected," said the statement.

"As a precautionary measure, AVA is also suspending the import and sale of all milk and milk products from China with immediate effect," added the statement.

Consumers who have bought Yili brand "Choice Dairy Fruit Bar Yogurt Flavoured Ice Confection" and "Dutch Lady" brand of strawberry flavoured milk (manufactured in China) are advised not to consume them.

AVA said retailers and importers have also been instructed to recall these products and these products will be withheld from sale until they have cleared the necessary tests.

AVA has also instructed local food manufacturers to stop the use of milk and milk products from China as ingredients until the completion of its investigations. Consignments which have just arrived or are on the way will also be withheld from sale.

As regards infant formula, AVA reassures the public that there is no such import from China. Infant formulas sold in Singapore are safe for consumption, it said.

Singapore not completely immune from tsunamis: expert

AFP Yahoo News 19 Sep 08;

Singapore, one of Asia's wealthiest cities, is not completely immune from a tsunami and should prepare for the possibility, an expert on coastal areas warned Friday.

The island-state can be hit by a tsunami generated from three locations and the waves could damage key coastal infrastructure without being too high, said Professor Wong Poh Poh of the National University of Singapore geography department.

"It's not that we are totally immune. No, we are not immune," Wong said.

He was speaking at a news conference to launch a report, by the aid and development organisation World Vision, on the impact of climate change on poor people.

To cause damage, waves hitting Singapore need not be as huge as the ones that devastated Indonesia's Aceh in December 2004, killing 168,000 people, Wong said.

Aceh was struck by a wave about 10 metres (33 feet) high.

"We don't need 10 metres. The problem with Singapore is... we have a lot of infrastructure on the coast. All you need is a very low wave to just come in and hit certain areas," he said.

"Changi Airport will be very vulnerable," he said, adding the man-made island of Jurong which houses a sprawling petrochemical complex is also at risk, and urged the government to commission a study on tsunamis.

Singapore not tsunami-proof
Antara 20 Sep 08;

Batam, Riau province, (ANTARA News) - Singapore is not at all free from the risk of being devastated by a tsunami, an expert from the National Geography Department of the University of Singapore, Professor Wong Poh Poh, said here Saturday.

"It doesn`t take a tidal wave as high as the one that engulfed Aceh to destroy many key infrastructures in Singapore," he said in a talk with Channel News Asia monitored by Antara here.

Almost four years ago (December 26, 2008), a tsunami (10m high) hit Aceh and killed 168,000 people.

The problem in Singapore, said Wong, was that most of its infrastructures were located near beaches.

"It will only take a low tidal wave to hit and destroy those infrastructures and the areas around them," he said.

Prof Wong said Singapore`s international airport (Changi) could be easily destroyed by a tsunami, and so could housing complexes in the Petrokimia area, Jurong Island.

Besides Singapore, tourist resorts and residential areas on Batam Island`s beaches (about 20 km from Changi and Jurong were also vulnerable to the destructive force of a tsunami, he said. (*)

Future Fury: Hurricane Effects Will Only Get Worse

Andrea Thompson, LiveScience.com 19 Sep 08;

The Caribbean and Gulf Coast have seen a spate of devastating hurricanes in recent years that have cost billions of dollars and thousands of lives. As residents recover from the latest hits, they may wonder about the potential for future Ikes and Katrinas.

Hurricanes, of course, are nothing new to the Atlantic and Gulf of Mexico, where tropical storms form between June and November each year.

But many factors, both natural and man-made, can affect the number, strength, size and impact of the storms that form each season. For example, the recent surge in storms followed an almost two-decade lull that was part of a natural cycle in hurricane formation.

During that lull, new coastal residents built homes in what they thought was a paradise. But now they've found out just how susceptible they are to nature's wrath. And it looks like the situation might only get worse.

Coastal build-up

In 2003, more than half the U.S. population (or about 153 million people) lived along the Gulf and Southeastern U.S. coastline - an increase of 33 million people from 1980 - and that number is just expected to keep rising.

The buildup of these communities in recent decades and the environmental damage that development has caused exacerbate the impact of hurricanes.

"There's been an explosion of population along our coast," said Amanda Staudt, a climate scientist with the National Wildlife Federation (NWF). "That's just putting a lot more people in harm's way."

This is particularly true in Florida, Texas and North Carolina, where populations are increasing the fastest. Hurricanes are especially a threat for homes right on the beach or on barrier islands, such as Galveston, because they receive the full brunt of a hurricane's storm surge.

Coastal features such as barrier islands and wetlands act as natural protection against a hurricane's storm surge, slowing it down and absorbing some of the impact. Studies have shown that every mile of wetlands reduces storm surge by about 3 to 9 inches and every acre reduces the cost of damages from a storm by $3,300, Staudt said.

"Our wetlands and barrier islands ... are our first line of defense," she said.

But the development boom in coastal areas has damaged these natural defenses, putting coastal residents even more at risk.

"The more we develop, the more we lose," Staudt told LiveScience.

The National Oceanic and Atmospheric Administration estimates that since the 1700s, the lower 48 states have lost more than half of their wetlands. While not all of that acreage loss is right along the coast, and some is likely a result of natural changes along the shoreline, a good chunk is due to development.

For instance, some of the Katrina damage to New Orleans was partly a result of the damage to the protective wetlands along Louisiana's coast. Development and subsidence, or outright sinking, of the state's coastline today mean that Louisiana loses an area of wetlands equivalent to the size of 32 football fields every day, according to the NWF.

Many hurricane experts have warned for years against destructive coastal development and imprudent policies that encourage people to build in coastal areas, but that often doesn't stop the building.

Warmer seas

Meanwhile, the oceans are growing warmer. Global ocean temperatures have risen by about 0.2 degrees Fahrenheit (0.1 degrees Celsius) in the last 30 years. And hurricanes are fueled by the warm, moist air over the tropical Atlantic and the Gulf of Mexico. The warmer the ocean surface, the more energy is available to fuel a storm's ferocious winds.

Scientists have predicted that as global warming continues to heat up the ocean, hurricanes could become more frequent, more intense or both, and several scientists think that change is already evident.

As sea surface temperatures rise, they provide more fuel to the convection that drives the swirling storms. This added energy could notch up the speed of hurricanes' winds (though several scientists say the winds can only increase so much). One recent study suggested that the strongest hurricanes in particular would get a bump from warming waters.

The rainfall brought by hurricanes could also increase because as the Earth's atmosphere also warms, it can hold more moisture. Studies have shown that one of the most damaging parts of a storm can actually be the rain it dumps on inland areas.

Rising sea levels could increase the damage wrought to coastal areas by a hurricane's storm surge.

Warmer water, and more of it, could also mean more opportunities for storms to form. Another recent study suggested that global warming could extend the hurricane season; as the warm water areas in the Atlantic expand, there could be more opportunities for storm formation, particularly early in the season.

Natural cycles

Of course, the changes man has made to coastlines and the climate system aren't the only thing affecting the intensity of any particular hurricane season. Mother Nature provides plenty of variation as well.

Natural fluctuations in the climate that occur over a matter of years, such as El Nino and its sister La Nina, can also affect how busy the Atlantic hurricane season is.

El Nino events, which occur when tropical Pacific waters become warmer, can change the flow of prevailing air currents and stifle hurricane development in the Atlantic. Forecasters think that an El Nino event was the reason for the calm 2006 hurricane season, which came after two of the busiest years for hurricanes on record. La Ninas (when tropical Pacific water become cooler) typically mean more hurricanes.

Another natural cycle, called the Atlantic Multidecadal Oscillation, can affect hurricane frequency over several decades through changes in sea surface temperatures, and is thought to be linked to the relative lull in hurricanes during the 1970s and 80s.

While natural cycles can affect hurricane activity from year-to-year or even decade-to-decade, most climate scientists think that global warming will continue to fuel these storms, and accompanied by the increasing coastal population and environmental degradation, lead to the "increasing destructive power of storms," Staudt said.

Sri Lanka hopes wildlife glories will attract new tourists

Mel Gunasekera Yahoo News 18 Sep 08;

With wetlands and jungles teeming with colourful butterflies and exotic primates, Sri Lanka is planning to lure a new type of tourist who prefers wildlife to beach life.

As well as at least five species of primates -- including the purple-faced leaf monkey and the hanuman langur -- the island boasts hundreds of lakes and lush paddy fields for visitors to explore.

Langurs, with their long eyelashes to avoid the glare while feeding on treetops, are believed to be incarnations of the Hindu monkey god Hanuman from whom they get their black markings.

Legend has it that Hanuman burnt his face, hands and feet after he got caught in a fire while rescuing a queen from Sri Lanka's forests.

"Primates have always captured peoples' imagination -- perhaps it is because they look and behave so much like humans," Gehan de Silva Wijeyeratne, head of Jetwing eco-holidays told AFP, while on the trail of the toque monkey in Sigiriya, 170 kilometres (110 miles) north of Colombo.

"Sri Lanka is very rich in primate species and large numbers of primates can be easily observed," he said.

Sigiriya, a world heritage site and home to a stunning fifth-century rock fortress, is a hotspot for observing langurs and toques.

"The animals look very comfortable with people around them," said Manduka Premaratne, a local visitor, as he watched dozens of monkeys play and groom each other.

Primates can also be found in the nearby historic sites of Polonnaruwa, Kandy, the southern city of Galle and the wetlands around Colombo.

The critically endangered purple-faced leaf monkey can occasionally be spotted in Colombo's suburbs, while the brown saucer-eyed loris lives in the island's Horton Plains national park.

"The loris is rare. Few sightings have been made," said Nalin Perera of the International Conservation Union in Sri Lanka.

Traditionally the loris has been killed for the supposed medicinal properties of its body parts.

Sri Lanka is also a paradise for butterflies, dragonflies, leopards and exotic birds, who are found in abundance in the island's rainforests and jungles, said Chandra Jayawardene, a naturalist at the Hotel Vil Uyana.

Around 243 species of butterflies and 118 species of dragonflies have been discovered so far, Jayawardene said.

Wijeyeratne said the leisure industry was counting on Sri Lanka's natural wonders to bring foreign visitors to the tropical island, adding that "conventional tourism is in trouble".

Sri Lanka's golden beaches, tea plantations and ancient religious sites have long attracted visitors, but numbers have been falling as a nasty civil war drags on.

Arrivals in July dropped 25 percent to 32,982 over the same period in 2007, according to Sri Lanka Tourism, amid a spate of bomb attacks and heavy fighting between troops and Tamil Tiger rebels in the north.

Authorities had forecast 600,000 visitors this year, bringing in 550 million dollars, but figures are falling well short of such projections.

Tourism revenue for the six months to June this year totalled 175 million dollars, according to Sri Lanka's central bank, while the number of visitors from January to July this year was 225,000.

"I don't think we will cross 600,000 this year because of the terrorist problem," Sri Lanka's tourism chief, Renton de Alwis said.

"But we hope that environmental tourism can be a big help to us in the future."

Troubled waters: Did we really save the whale?

Blue whales have been spotted in the Irish Sea, and humpbacks have been removed from the endangered list. But did we really save the whale? The acclaimed writer Philip Hoare, who has spent four years researching these magnificent creatures, reports

The Independent 20 Sep 08;

Twenty years ago, the writer and environmentalist Heathcote Williams launched an epic plea for the future of the whale. His televised poem Whale Nation – with its closing lines, "From space, the planet is blue / From space, the planet is the territory / Not of humans, but of the whale" – was a hymn to the beauty, majesty and intelligence of the largest mammals on earth, as well as a prayer for their protection.

And the film was a stunning success around the world, attracting some of the largest audiences ever seen for a "nature" programme; the published version, described as a modern version of T S Eliot's The Wasteland, was a major bestseller too, with the American rights alone selling for $100,000 – a figure that prompted headlines at the time.

Whale Nation became the most powerful argument for the newly instigated worldwide ban on whaling – and for a moment, back in 1988, it seemed as if a shameful chapter in human history might finally be drawing to a close.

Yet two decades on, the issues that Williams so passionately exposed are still with us. The Japanese are still hunting in the Southern Ocean – supposedly a whale sanctuary. Since 1987, when the international moratorium took effect, an astonishing 25,000 great whales have been killed.

Under its Antarctic Research Programme, known as JARPA, and its North Pacific equivalent, known as JARPN, Japan has killed 7,900 minke whales, 243 Bryde's whales and 140 sei whales, as well as 38 sperm whales, which it resumed hunting in 2000. In 2006, JARPA II took 1,073 minke whales – known to their hunters as "cockroaches of the sea" – and added 50 fin whales to the tally. These cetaceans (from the Greek for "sea monster") died under the aegis of "scientific research". Only the piratical disruptions of protesters aboard the Sea Shepherd, who dogged the Japanese whaling fleet earlier this year, prevented the hunting of much-loved humpback whales in 2008.

And it's not only the Japanese. Throughout the world, whales and dolphins – now known to be as intelligent as primates – are still kept as performing animals in oceanariums. Since the 1960s, when killer whales were first taken from the wild, 200 have died in captivity. Whales and dolphins still die, too, in their thousands as "bycatch" in commercial fishing. They suffer from ever louder military and industrial sonar, causing mass strandings in which hundreds of whales and dolphins have been known to perish on beaches, slowly crushing their internal organs under their own weight. Meanwhile, the environmental threat to whales is greater than ever. As oceans warm and the oxygen content of the sea is impaired and acidifies, the zooplankton and small fish on which whales feed move further north, threatening long-held feeding and migration patterns.

One hundred and fifty years ago, in the most famous whaling book of all, Moby-Dick, Herman Melville asked presciently, "Does the Whale's Magnitude Diminish? – Will He Perish?" The answer is still hard to pin down.

For the past four years, I have embarked on my own voyage of discovery in the footsteps of Melville's ambiguous narrator, Ishmael. Writing a book about the vexed relationship between man and whale, and making a new BBC documentary, Arena: The Hunt for Moby-Dick, to be shown this evening, has been an eye-opening process.

In the ongoing battle between human history and natural history, one particular species, the sperm whale – Physeter macrocephalus, the real-life model for Moby-Dick – stands alone, not least because its persecution coincides with the rise of the Industrial Revolution. This was a whale seemingly put on earth to advance man's progress. Bizarrely blunt in shape, its pugnacious forehead full of oil, which when pierced, spurted out, causing early sailors to mistake it for the animal's semen – hence its name. But this oil – spermaceti – also supplied the world with light and lubrication. It made fortunes, and enabled empires.

For centuries man's contact with the sperm whale was wreathed in myth and legend. Sperm whales washed up on the coast of Europe were regarded as ill omens, auguring plague or famine. It wasn't until the beginning of the 18th century that they were actively hunted, when the Quaker captain, Christopher Hussey, was out hunting right whales off Nantucket. Blown off course, his ship happened upon a school of sperm whales feeding in the deep waters of the continental shelf. Soon the ports of New England had become the worldwide centre of whaling expertise.

Until the discovery of crude oil in Titusville, Pennsylvannia, in 1859, the world was lit by whale oil. The "Whaling City" of New Bedford, Massachusetts, from which Melville sailed on his 1840 whaling voyage, was the richest city in America. Its ships travelled further and further afield – as far as the South Seas – in search of their precious commodity. They were the equivalent of modern-day oil tankers. They exported the budding economic might of America around the globe – though as Hal Whitehead, the pre-eminent scientist specialising in the study of sperm whales, remarks, the whalers also "left behind diseases, non-native animals (especially rats), technology, and their genes".

Not to be outdone, Britain sent out its own fleet. Whale ships that would otherwise be empty took supplies to Australia. In his 1839 book, The Natural History of the Sperm Whale, Thomas Beale wrote: "Evidence inclines us to believe that these colonies would never have existed had it not been for whaling vessels approaching their shores ... It is a fact, that the original settlers at Botany Bay were more than once saved from starvation by the timely arrival of some whaling vessels." And if they helped lay the foundations of the British Empire, they also helped the country survive two World Wars: in both conflicts, the British fleet harvested whales to turn into nitro-glycerine and thus fuel the fighting machine. Soldiers even treated trench-foot by rubbing whale oil into their feet.

But just as whales helped further the Industrial Revolution, so it hastened their destruction. With the invention of steam engines and grenade harpoons, late-19th- and early-20th-century whalers could pursue the faster rorqual whales – such as the blue whale, the largest animal ever to have lived – which had previously eluded them. In 1951 alone, more whales were killed in one year by the British, Norwegian, Japanese and Soviet fleets than in a century and a half of American whaling.

And as time passed, new uses were found for the arcane commodity of whale oil in the post-modern world. Since it doesn't freeze in sub-zero temperatures, spermaceti was used in Nasa's space missions – no substitute could be found for this natural lubricant. Even now, the Hubble space telescope and the Voyager space probe are careening into infinity, oiled by whales.

Hal Whitehead, the Cambridge-educated scientist who now works at Dalhousie University in Newfoundland, has devoted most of his adult life to the study of sperm whales. He has calculated that their population was reduced from one-and-a-half million before hunting began to a present figure of 360,000.

The whalers often took the biggest animals – the largest bull sperm whales, or their female equivalents – and their removal has had a drastic effect on the current population. Whitehead has proved that sperm whales are highly intelligent animals, capable of communicating in complex series of sonar clicks. The brain of a mature sperm whale weighs up to 17 pounds – the heaviest of any known animal – with a complex neocortex structure. If allowances are made for the animals' blubber, the body-to-brain-size ratio (the Encephalization Quotient, a rough estimate of possible intelligence) of sperm whales indicates significant acumen. Having swum eye-to-eye with these creatures in the Azores – and felt my ribcage scanned by the animals' echo location – I can bear personal testament to their placid and obviously sentient nature.

Studies show that cetaceans can solve problems and use tools, exhibit joy and grief, and live in complex societies. Not only that, but they also pass on these abilities in "cultural transmission" – a gift that has become a problem in itself. Twentieth-century whaling may have destroyed "not just numerous individuals," says Whitehead, "but also the cultural knowledge that they harboured relating to how to exploit certain habitats and areas". The remaining animals have also experienced lower birth rates as a result, and the slow-breeding sperm whale population is growing at a mere 1 per cent a year. The 1986 moratorium, which took effect the following year, may have come only just in time for Physeter.

The blue whale, too, may be recovering from the appalling culls of the 20th century. By the time of the moratorium, the blue whale (Balaenoptera musculus – a little joke by Carl Linneaus, musculus meaning both "muscular" and "mouselike") was regarded as "commercially extinct". In fact, it was commerce, or the lack of it, which ultimately saved it. The hunting of whales stopped largely because there were so few of them left – and cynics note that the move to ban international whaling was championed by America only because its own whaling industry had since fallen into decrepitude. As with the 19th-century abolition of slavery, it was exigency rather than outrage which provided the whale's reprieve.

Neither pro- nor anti-whaling members of the International Whaling Commission ever forget that the 1986 ban was – and is – a temporary and voluntary measure. Norway merely ignored it and continued to hunt minke whales – the same animals watched by its tourists, with disastrous results. One boatload of horrified whale-watchers looked on aghast as the whales they were watching were harpooned by hunters.

But just as the Norwegians claim historical precedence for their whaling, we should also see Japan's actions in context. Their industry is relatively recent (although the island nation has a long tradition of shore whaling). It began in the 1930s, using techniques taught by Norwegian whalers. But it wasn't until the post-war years that it burgeoned, encouraged by the occupying powers under General McArthur, who had the decommissioned ships of the Japanese navy converted into a whaling fleet. One can understand Japanese resentment at what they see as Western hypocrisy.

In a country where whale meat was served in school lunches until the 1970s, it irks to be lectured on the subject. "It's not because Japanese want to eat whale meat," Ayako Okubo, a spokesman for a Japanese whaling company, told the New York Times last year. "It's because they don't like being told not to eat it by foreigners." Some contest that it was America's over-use of pressure on the Japanese – and the moral weight of the environmental lobby – that pushed Japan into its intransigent position.

Indeed, in a contrarian article for Atlantic Monthly, the academics William Aron, William Burke and Milton Freeman argued that "the ongoing campaign to ban all commercial whaling is driven by politics rather than science, and is setting a terrible precedent". The authors proposed that the "cynical actions of the IWC's anti-whaling nations constitute a clear warning to all nations engaged in negotiating multilateral environments". In other words, by saving the whale, the world itself might be lost. Now, as pro-whaling nations push harder for a resumption of legitimate whaling, more pragmatic campaigners say that the only way to stop the Japanese plundering the Southern Ocean is to permit limited commercial whaling, which would allow some control of a currently anarchic situation.

Yet given such pragmatic arguments, after my own experiences I'd still find it impossible to stand on a prow from which an explosive harpoon was about to be fired and not physically restrain the harpooneer from his task. There is no more emotive target in the animal kingdom, and over years of contact with whales, I've been torn between the rational appeal of scientific study and the pitfalls of seductive anthropomorphism.

For the scientists of the Provincetown Center for Coastal Studies in Cape Cod, it is tiny organisms that hold their attention, even though the subject of their research is the North Atlantic right whale (Eubalaena glacialis, "true whale of ice"). Their common name came about because their foot-thick blubber meant that they floated conveniently when dead (rather than sinking to the bottom as other whales will if not first secured). The legacy of hunting has reduced their number to just 350 animals.

Each late winter and spring, these ponderous beasts plough across Cape Cod Bay, hoovering up a ton or more of zooplankton a day to support their enormous bulk. They are a bizarre sight, huge rotund animals surmounted with barnacle-encrusted crests called "callosities". Their baleen – much prized as whalebone in a pre-plastic age, and once used for everything from umbrellas and corset stays to carriage suspension and Venetian blinds – grows in plates up to nine-feet long from their upper jaws. When their garage-sized mouths open, the effect is of some surreal musical instrument.

The right whales choose one of the world's busiest shipping lanes in which to feed, a habit which exposes them, like the humpbacks which share their feeding grounds, to present danger. They may be caught in fishing gear – the Center for Coastal Studies reports that 50 per cent of right whales and humpbacks are thus entangled. Many never escape; others are scarred for life. This summer, I saw one humpback, named Meteor, with a tail so badly torn it resembled the dog-eared page of a book.

If right whales are rare and, for the public at least, difficult to see (only the Center's scientists are allowed closer than 500 feet to the right whales), then humpbacks are a different matter. Prone to surface display, the humpback was called "the most gamesome and light-hearted of all the whales" by Melville, "making more gay foam and white water" than any other. Megaptera novaeangliae ("big-winged New Englander") – its scientific name – is a real trouper.

In my own work with the Center, I've helped identify humpbacks from the black and white patterns on the underside of their tails, or flukes. These patterns are as unique as a fingerprint is to a human, and allow data to be collected about the animal's gender, breeding and patterns of migration. It's a kind of whale census. But the sublime sight of a whale's tail, water running off it like a curtain of mercury before it dips into the sea, is as nothing compared to other humpback behaviour.

A 50-ton and 50ft-long humpback will throw itself entirely out of the water in an act of acrobatics known as "breaching". No one knows why whales do this – and most of the 85 species do. It may be a means of communication; a way of dislodging parasites; or perhaps it's just fun. It certainly looks like it – if I could launch myself out of the water and 20 feet into the air, I'm sure I'd find it addictive too. But what has surprised me, after years of observing these animals, is how often they chose to breach within sight of the whalewatch boats. It is as if they like an audience.

In the evolving relationship between humans and whales, the whale has learned to use man and his machines. Recently, I was on a whalewatch boat with Dennis Minsky, one of the Center for Coastal Studies' naturalists, when a large female humpback came so near that Minsky quipped it could only get closer "if she got into the boat". We could see every detail of the animal. Rolling on its back, the whale displayed the rorqual pleats which expand as it swallows swimming-pool-size gulps of water, then contract to expel the mouthful, catching fish in its baleen like pasta in a strainer. Then, with the nonchalance of a cow in an English field, the female began to rub her belly on the prow of the boat. We were being used as a scratching post.

I've often watched humpbacks blow "bubble nets" underwater, creating spiralling circles to corral their prey, then rising in the middle, mouths wide open, to claim their prize. It is clear, from their proximity, that they use the side of the vessel as a buffer to push their catch to the surface. It works both ways, too. Spanish fishermen work with pods of killer whales which chase their catch into shallow waters, where cetaceans and humans benefit from the fishes' confusion.

Other inter-species relationships are more problematic. In the 1960s, the controversial scientist John C Lilly proposed that whales and dolphins were so intelligent that they should be considered as a parallel, alien life force sharing our Earth. Lilly even declared a new cetacean language, delphinese, and persuaded one female researcher to live in a semi-submerged house so that she could spend more time in intimate observation of her dolphin charges. Unfortunately, Lilly's wilder theories caused him to be shunned by his fellow scientists. Matters weren't helped when he began experiments into the use of LSD on human guinea pigs.

Lilly's left-field claims had the effect of setting back cetacean research – cautious scientists didn't want to be associated with such work. Nowadays, their renewed efforts are concentrated towards ensuring species stay alive. It is another irony that the roll-call of new species is being added to even as recognised species face extinction. In the time it took to write my book, the Yangste river dolphin, a strange, blind, freshwater cetacean, was declared extinct. The North Atlantic right whale will probably go the same way by the end of the century. Yet, amazingly, there are beaked whales or ziphiids – deep-diving cetaceans confined to the open ocean – which have never yet been seen alive, and are known only from bones recovered from beaches. It is a salutary notion that large marine mammals may be swimming in the world's oceans, unidentified by man.

In recent years, the humpbacks of Cape Cod have been particularly plentiful. Thousands of whales return here from their winter migration to the Caribbean. In these fertile, shallow waters, they feed on vast schools of sand eels. At one point last year I found myself on a boat surrounded by 75 humpbacks. In every direction there were spouts and splashes of whales. It was an Edenic sight; the ocean was alive with animals. Even the experienced naturalists I was with put down their cameras and clipboards and stared in wonder.

Maybe we did save the whale after all. As Richard Sabin, curator of sea mammals at the Natural History Museum, told me recently, there have been reports of blue whales swimming up the Irish Sea, and last month, the humpback was officially removed from the endangered list. But that may be an equivocal victory, reviving fears that whaling nations might once again declare open season on these animals. For all their apparently successful recovery, whales still face plenty of threats from the two-legged, gravity-bound creatures with which they happen to share the earth.

The five most endangered whales
The Independent 20 Sep 08;

North Atlantic right whale. Fewer than 350 animals. Given such a small gene pool, scientists fear for its survival. One possible solution may be to reinvigorate the northern whale's genes with those of its more successful southern counterpart off South Africa. Recent reports of pregnant North Atlantic right whales killed by ship strikes off the north-eastern seaboard of the US do not augur well for the species.

Fewer than 350 animals

Western Pacific grey whale. The most endangered of all great whales, and a potential victim of oil and gas exploitation off Sakhalin Island on the far east of Russia. Likely oil spills threaten the habitat of a population of as few as 120 individuals. The death of just three females could mean the extinction of the species.

Fewer than 120 animals

Bowhead. Once known as the common or Greenland whale, this cetacean was targeted by British whalers in the 18th and 19th centuries; William Scoresby of Whitby took 533 in his whaling career alone. The bowhead – a close relative of the right whale – is rarely seen as it confines itself to Arctic waters, using its huge head to break ice in order to breathe. It is threatened by the receding polar ice, and by the probable expansion of the oil industry.

Fewer than 120 animals

Narwhal. Another Arctic whale, its 10ft-long tusk – in fact, an overgrown tooth – is the source of the legendary unicorn's horn. (Medieval hunters and apothecaries conspired to create a market for its supposed properties as an antidote for poison and melancholia.) Named after the Norwegian for 'corpse whale', it is still hunted by aboriginal peoples, who can sell its ivory tusks for up to $7,000 a piece. It too is threatened by the shrinking north polar ice cap.

Fewer than 120 animals

Cook Inlet beluga whales. Named after the Russian for white, belugas are known as canaries of the sea for their vocal chirrups and whistles. Common in the Arctic and sub-Arctic waters, they are under threat from pollutants such as mercury and PCBs: belugas that die in Canada's St Lawrence riverway are so contaminated their bodies are classified as toxic waste. Oil pollution in the Cook Inlet, Alaska, has caused the isolated population there to collapse to near extinction.

Australia to launch ambitious global carbon capture scheme

Yahoo News 19 Sep 08;

Australia will launch a multi-million dollar international carbon capture and storage institute to fight global warming, Prime Minister Kevin Rudd announced Friday.

Rudd said the plan would be the centrepiece of his address to the United Nations General Assembly in New York next week, adding that British Prime Minister Gordon Brown had already offered his support.

The institute would promote research and investment to help meet a G8 commitment to have at least 20 industrial scale carbon capture and storage (CSS) projects in operation by 2020.

CSS involves capturing carbon dioxide as it is released into the atmosphere, compressing it and then pumping it into depleted oil and gas fields or other safe underground chambers.

Carbon dioxide and other greenhouse gases blamed for global warming are produced by burning fossil fuels and Rudd noted that Australia is the world's largest exporter of coal.

Any effective solution to climate change must deal with clean coal and CSS could be a large large part of the solution, he told a news conference.

"We the government want this global carbon and storage institute in Australia to be the global go-to place across the board for clean coal technologies and their application. That is the ambition.

"Rather than simply put an idea out there, we have decided that we need to have some skin in the game (make a significant investment)," he said.

"So we will be providing up to 100 million dollars (80 million US) a year to fund this global carbon capture and storage institute."

Rudd said CSS had the potential to capture nine billion tonnes of carbon by 2050, about 20 percent of the reduction needed to cap atmospheric levels at 450 parts per million.

There are just five pilot projects worldwide, including one in Australia's Victoria state.

Rudd, whose first act when he took office last year was to ratify the Kyoto Protocol on global warming, said there was a danger the G8 ambition would end up as simply a politically pious statement.
