Human hair offers eco-friendly way to battle Gulf oil spill
(05/02/2010) An environmental group is organizing collection of human hair from salons and barber shops across the country as part of an effort to clean up the massive oil spill triggered by last month's deadly explosion of the Deepwater Horizon rig in the Gulf of Mexico.
Hair salons enlisted in eco-friendly approach to Gulf oil spill clean-up
(05/01/2010) An environmental group is organizing collection of human hair from salons and barber shops across the country in an effort to soak up oil spilled in the aftermath of last month's accident involving Deepwater Horizon rig, which has been leaking thousands of barrels of oil into the Gulf daily since a deadly explosion on April 20.
The Oily History of Offshore Operations: From Venezuela to the Gulf
(05/01/2010) Though undoubtedly shocking and disconcerting, the recent BP oil spill in the Gulf of Mexico is hardly the first incident of its kind in the region. Indeed, as I watched the footage of the ominous oil spill approaching the ecologically sensitive coast of Louisiana, I was struck with a profound sense of déjà vu. Long ago, while researching my dissertation on the environmental history of the petroleum industry in Venezuela, I combed through archives and libraries in the U.S., Britain and South America to uncover the oil companies’ sordid past. Starting in the 1920s, American and British subsidiaries of Standard Oil of New Jersey, Gulf and Royal Dutch Shell turned environmentally pristine Lake Maracaibo, which empties out into the Gulf of Venezuela and the Caribbean, into toxic sludge
Oil spill in Gulf of Mexico heading towards full-scale environmental disaster
(04/29/2010) With the news that the amount of oil leaking from below the surface of the Gulf of Mexico could be as much as five times the original estimate put forward by British oil-giant BP, the situation moved from worrisome to desperate.
NASA satellite image reveals massive oil spill
(04/26/2010) A newly released NASA satellite image reveals oil leaking from the BP oil rig that sank after it exploded April 20, 2010. The explosion killed 11 workers.
After oil rig explosion, leaking crude threatens Gulf of Mexico
(04/26/2010) Just weeks after a Chinese coal barge rammed the Great Barrier Reef, cutting a nearly two-mile swath through the reef and spilling three tons of engine fuel, fragile marine ecosystems are again threatened. Last Tuesday a BP oil rig platform exploded in the Gulf of Mexico, likely killing eleven workers. The blast also left oil leaking from the drill hole estimated at 42,000 gallons (or 1,000 barrels) of oil per day.
Killer whales split into three separate species
(04/25/2010) Using genetic evidence scientists have discovered that the world’s killer whales, also known as orcas (Orcinus orca), likely represent at least three separate species.
World failing on every environmental issue: an op-ed for Earth Day
(04/22/2010) The biodiversity crisis, the climate crisis, the deforestation crisis: we are living in an age when environmental issues have moved from regional problems to global ones. A generation or two before ours and one might speak of saving the beauty of Northern California; conserving a single species—say the white rhino—from extinction; or preserving an ecological region like the Amazon. That was a different age. Today we speak of preserving world biodiversity, of saving the 'lungs of the planet', of mitigating global climate change. No longer are humans over-reaching in just one region, but we are overreaching the whole planet, stretching ecological systems to a breaking point. While we are aware of the issues that threaten the well-being of life on this planet, including our own, how are we progressing on solutions?
Close to a billion species: ocean exploration reveals shocking diversity of tiny marine life
(04/19/2010) Biologists worldwide may have to start re-evaluating their estimates of the number of species on Earth, since expeditions documenting the oceans' tiniest species have revealed shocking diversity: in the tens of millions of species, at least, and according to one researcher "closer to a billion". Fourteen field projects sent out by the Census of Marine Life focused on the oceans' smallest inhabitants: microbes, zooplankton, and tiny burrowing species inhabiting the deep sea bed. What they found was astounding.
Whiskas offers Critically Endangered species-flavored cat food
(04/13/2010) In a truly bizarre product offering, Whiskas presented a new line of bluefin tuna-flavored cat food before quickly eliminating the product "due to public concerns", according to Greenpeace UK.
New report finds millions of marine turtles killed by fisheries, not thousands
(04/06/2010) Humankind's appetite for seafood has had a bigger impact on the world's marine turtles than long thought. A new report by Conservation International (CI) in partnership with Duke University’s Project GloBAL (Global By-catch Assessment of Long-lived Species) finds that in the past eighteen years it is likely millions of marine turtles have been killed as bycatch by the world's fisheries.
History repeats itself: the path to extinction is still paved with greed and waste
(04/05/2010) As a child I read about the near-extinction of the American bison. Once the dominant species on America's Great Plains, I remember books illustrating how train-travelers would set their guns on open windows and shoot down bison by the hundreds as the locomotive sped through what was left of the wild west. The American bison plunged from an estimated 30 million to a few hundred at the opening of the 20th century. When I read about the bison's demise I remember thinking, with the characteristic superiority of a child, how such a thing could never happen today, that society has, in a word, 'progressed'. Grown-up now, the world has made me wiser: last month the international organization CITES (Convention on International Trade in Endangered Species) struck down a ban on the Critically Endangered Atlantic bluefin tuna. The story of the Atlantic bluefin tuna is a long and mostly irrational one—that is if one looks at the Atlantic bluefin from a scientific, ecologic, moral, or common-sense perspective.
BPA not just in food and water, but contaminating the ocean
(03/28/2010) Increasingly consumers are concerned about the chemical bisphenol A or more-widely known as BPA, which is present in certain plastics. The chemical is capable of leaching from plastic containers and liners into our food and drink. But now there's a new place BPA has shown up in surprisingly high concentrations: the world's oceans. Scientists have discovered that despite being known for their hardness, polycarbonate plastics actually decompose in oceans, leaching chemicals, including BPA, throughout the marine ecosystem.
'Very dramatic' changes in Greenland: ice loss spreads north
(03/28/2010) Over the past ten years scientists have measured increasing ice loss along southern Greenland. Now a new study in Geophysical Research Letters shows that the ice loss has spread north with likely consequences for global sea level rise.
CITES chooses 'commerce' over sharks, leaving endangered species vulnerable
(03/23/2010) Only the porbeagle shark received protection today from the Convention on International Trade in Endangered Species (CITES). Seven other shark species failed to win international protection despite plummeting populations due to overfishing. Once again, Japan led the opposition to regulating the trade in white-tipped sharks and scalloped hammerheads, including two look-alike species: the great hammerhead and the smooth hammerhead. Japan has dominated the CITES meeting, successfully leading resistance to banning the trade in the Critically Endangered Atlantic bluefin tuna and against monitoring the coral trade.
Rise in poaching pushes CITES to vote 'no' to ivory sales
(03/22/2010) The Convention on International Trade in Endangered Species (CITES) has pleased conservationists with its decision to not allow the one-off sales of ivory from government stockpiles in Tanzania and Zambia given the recent rise in elephants poaching in Africa.
CITES rejects monitoring of coral trade
(03/21/2010) After denying protection to polar bears, sharks, and the Critically Endangered Atlantic bluefin tuna, the Convention on International Trade in Endangered Species (CITES) has today voted against additional protections for harvested coral species, according to TRAFFIC, a wildlife trade monitoring group. The joint US and EU measure would have put in place scientific and trade monitoring of over thirty species of red and pink coral in the Mediterranean and western Pacific.
Critically Endangered bluefin tuna receives no reprieve from CITES
(03/18/2010) A proposal to totally ban the trade in the Critically Endangered Atlantic bluefin tuna failed at the Convention on International Trade in Endangered Species (CITES), surprising many who saw positive signs leading up to the meeting of a successful ban.
High Arctic species plummeting across the board, others Arctic residents on the rise
(03/18/2010) Between 1970 and 2004 species populations in the high Arctic have declined by 26 percent, according to the first report by the Arctic Species Trend Index (ASTI). While this may be a natural cycle, scientists are concerned that environmental impacts such as climate change are worsening natural population fluctuations in the high Arctic. Declining species include lemmings, red knot, and caribou. "Rapid changes to the Arctic’s ecosystems will have consequences for the Arctic that will be felt globally. The Arctic is host to abundant and diverse wildlife populations, many of which migrate annually from all regions of the globe. This region acts as a critical component in the Earth’s physical, chemical, and biological regulatory system," lead-author Louise McRae from the Zoological Society of London (ZSL) said in a press release.
Analysis shows Borneo can say 'no' to coal power
(03/17/2010) Plans for a coal power plant in the Malaysian state of Sabah in northern Borneo have run into stiff opposition. Environmentalists say the coal plant could damage extensive coral reef systems, pollute water supplies, open rainforests to mining, and contribute to global climate change, undercutting Sabah's image as a 'green' destination. The federal government contends that the coal plant is necessary to fix Sabah's energy problems. However, a recent energy audit by the Renewable and Appropriate Energy Laboratory (RAEL) at the University of California Berkeley shows that pollution-intensive coal doesn't have to be in Sabah's future.
Sharks lose out at UN meeting
(03/17/2010) An effort to bolster conservation measures for plummeting shark populations was defeated yesterday at the Convention on International Trade in Endangered Species (CITES), according to the AP. The nonbinding measure would have increased transparency in the shark trade and produced research on illegal fishing for sharks.
Video: no sunlight, no food, frozen conditions, but NASA finds complex life
(03/16/2010) In a discovery at the bottom of the world that could have implications on the search for extraterrestrial life, researchers were astounded to find an amphipod swimming beneath a massive Antarctic ice sheet.
Falklands Dispute: Argentine Sovereignty Won’t Solve the Problem
(03/15/2010) With Britain now moving to explore for oil and gas in the Falkland Islands, Argentina has cried foul. Buenos Aires claims that the Falklands, or the Malvinas as Argentines refer to the islands, represent a "colonial enclave" in the south Atlantic. The islands have been a British possession since 1833, and the local inhabitants consider themselves thoroughly British. Yet, Argentina claims the Malvinas as the country inherited them from the Spanish crown in the early 1800s. In 1982 Argentina seized the islands but was later expelled by a British naval force. The war was short but bloody, costing 650 Argentine and 250 British lives.
Sharks swim safe around the Maldives
(03/11/2010) Sharks that dwell in the Maldives can breathe a sigh of relief: the island nation has declared 90,000 square kilometers of the Indian Ocean a safe-haven for sharks, banning shark fishing as well as any trade in shark fins.
New cuttlefish discovered in India
(03/08/2010) A new species of cuttlefish has been discovered on the Southern tip of India, according to The Hindu. Discovered in Tamil Nadu, along the coast of the town of Colachel, the species has been named sepia vecchioni.
Massive methane leak in Arctic could trigger abrupt warming
(03/04/2010) Methane, a greenhouse gas 30 times more potent than carbon, is spewing from what was believed to be an impermeable barrier in Siberia in amounts equal to methane releases from the world's oceans. The discovery has lead researchers to fear the possibility of abrupt climate warming. According to the study published in Science, subsea permafrost below the East Siberian Arctic Shelf has become compromised, leaking vast amounts of methane into the atmosphere.
Octopus pretends to be flounder to avoid predators
(03/04/2010) Marine researchers have discovered the Atlantic longarm octopus mimicking not only the color and appearance of the peacock flounder, but also its unique style of swimming in order to convince predators it's something it's not.
Healthy coral reefs produce clouds and precipitation
(03/03/2010) Twenty years of research has led Dr. Graham Jones of Australia's Southern Cross University to discover a startling connection between coral reefs and coastal precipitation. According to Jones, a substance produced by thriving coral reefs seed clouds leading to precipitation in a long-standing natural process that is coming under threat due to climate change.
Photos: Giant iceberg breaks off Antarctica
(02/26/2010) An iceberg the size of Luxembourg broke off from Antarctica after it was hit by another iceberg, reports Reuters. The separation could impact ocean circulation and affect marine life say researchers.
Galapagos fur seals exploit warmer waters to establish colony off Peru
(02/25/2010) As suggested by their name, the Galapagos fur seals were once endemic to the Galapagos island chain off the coast of Ecuador. But in a warming world species are on the move, and the Galapagos fur seal is no exception. According to a recent story in Reuters the Galapagos fur seals have established what appears to be a permanent colony off the coast of Peru, 900 miles from their home.
With increased protection, Gulf of California marine life could recover
(02/22/2010) The Gulf of California's once rich marine ecosystem is in trouble. Surveys from 1999 and 2009 revealed that during the ten-year-period 60 percent of the areas showed signs of degradation, including the loss of top predators necessary to keep an ecosystem healthy, for example sharks, groupers, and snappers.
UN to protect seven migratory sharks, but Australia opts out
(02/17/2010) One hundred and thirteen countries have signed on to an agreement to protect seven migratory sharks currently threatened with extinction byway of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), according to the UN Environment Program (UNEP). The agreement prohibits hunting, fishing, or deliberate killing of the great white shark, basking shark, whale shark, porbeagle shark, spiny dogfish, as well as the shortfin and longfin mako sharks. However, Australia has declared it will ignore certain protections.
Expedition to photograph world's rarest cetacean threatened by lack of funding
(02/11/2010) Little known beyond the waters of the Gulf of California, the world's smallest cetacean (a group including whales, dolphins, and porpoises) is hanging on by a thread. The vaquita—which in Spanish means 'little cow'—has recently gained the dubious distinction of not only being the world's smallest cetacean, but the also the world's rarest. In 2006 it was announced that the Yangtze river dolphin, or baiji, was likely extinct, and conservationists fear the Critically Endangered 'little cow' is next. An expedition for this year is set to identify vaquita individuals, but even this is threatened by lack of funding.
First footage captured of giant sea serpent of the deep: the oarfish
(02/09/2010) Scientists have captured what they believe to be the first footage ever of the oarfish, the species likely responsible for legends told of sea serpents.
86 percent of dolphins and whales threatened by fishing nets
(02/07/2010) A new report from the United Nations Environment Program (UNEP) finds that almost 9 out of 10 toothed whales—including dolphins and porpoises—are threatened by entanglement and subsequent drowning from large-scale fishing operations equipment, such as gillnets, traps, longlines, and trawls. These operations threaten the highest percentage (86 percent) of the world's toothed whales.
The Amazongate fiasco
(02/03/2010) A claim published in the Sunday Times over the veracity of a statement published in an Intergovernmental Panel on Climate Change (IPCC) report may land the British newspaper in hot water. On Sunday, Jonathan Leake, Science & Environment Editor of the Sunday Times, accused the IPCC of making a "bogus rainforest claim" when it cited a report warning that up to 40 percent of the Amazon could be "drastically" affected by climate change. Climate change skeptics immediately seized on "Amazongate" as further evidence to discredit the IPCC just two weeks after it was found to be using shoddy glacier data in its 2007 climate assessment.
Jumbo squid explosion
(02/02/2010) Jumbo squid are back in the waters of Southern California and anglers are seeing an uptick in business, reports the Los Angeles Times.
Target stops sales of farm-raised salmon, citing environmental concerns
(01/27/2010) Citing environmental concerns, Target has stopped selling farmed salmon products nationwide.
Photos: Gelatinous Blobfish in danger
(01/26/2010) A species dubbed "the world's most miserable-looking fish" is at risk of extinction due to poor fishing practices, reports The Daily Telegraph.
Giant guano outcroppings win protection as bird habitat in Peru
(01/25/2010) The Peruvian government has moved to protect 33 guano sites—both islands and peninsulas—as well as surrounding waters in a bid to save declining bird populations.
Natural rafts carried Madagascar's unique wildlife to its shores
(01/20/2010) Imagine, forty million years ago a great tropical storm rises up on the eastern coast of Africa. Hundreds of trees are blown over and swept out to sea, but one harbors something special: inside a dry hollow rests a small lemur-like primate. Currents carry this tree and its passenger hundreds of miles until one gray morning it slides onto a faraway, unknown beach. The small mammal crawls out of its hollow and waddles, hungry and thirsty, onto the beach. Within hours, amid nearby tropical forests, it has found the sustenance it needs to survive: in a place that would one day be named Madagascar.
Climate change pushes massive Antarctic glacier past tipping point
(01/14/2010) A new study shows that a major Antarctic glacier has likely passed its tipping point, putting it on track to lose 50 percent of its ice in 100 years. Such a loss is estimated to raise global sea levels by 24 centimeters (9.4 inches), according to the study published in the Proceedings of Royal Society A.
World of Avatar: in real life
(01/13/2010) A number of media outlets are reporting a new type of depression: you could call it the Avatar blues. Some people seeing the new blockbuster film report becoming depressed afterwards because the world of Avatar, sporting six-legged creatures, flying lizards, and glowing organisms, is not real. Yet, to director James Cameron's credit, the alien world of Pandora is based on our own biological paradise—Earth. The wonders of Avatar are all around us, you just have to know where to look.
If protected coral reefs can recover from global warming damage
(01/10/2010) A study in the Caribbean has found that coral reefs can recover from global warming impacts, such as coral bleaching, if protected from fishing. Marine biologists have long been worried that coral reefs affected by climate change may be beyond recovery, however the new study published in PLoS ONE shows that alleviating another threat, overfishing, may allow coral reefs to cope with climate change.
Bottom-dwelling sea animals play surprising role in carbon sequestration
(01/07/2010) Researchers have long known that some marine animals, such as plankton, play big roles in the carbon cycle, but a new study shows that a long-ignored family of marine animals, the bottom-dwelling echinoderms, also do their part in the carbon cycle.
Coal plant could damage rainforest reserves, coral reefs, palm oil plantations in Malaysian Borneo
(12/20/2009) A proposed coal-fired power plant in Malaysian Borneo could damage the region's world-renowned coral reefs, pollute air and water supplies, open Sabah's biodiverse rainforests to mining, and undermine the state's effort to promote itself as a destination for "green" investment and ecotourism, warn environmentalists leading an effort to block the project. The scheme, which is backed by the federal Tenaga Nasional Berhad and state energy company, Sabah Electricity Sdn. Bhd, has faced strong opposition and already been forced to re-locate twice since it was conceived more than two years ago. The 300-MW plant is now planned for a coastal area that is situated in the middle of the Coral Triangle/Sulu Sulawesi Marine Ecoregion, an area renowned for astounding levels of biodiversity.
Uninhabited tropical island paradise seeks REDD funding to save it from loggers
(12/17/2009) Tetepare may be one of the last tropical island paradises left on earth. Headhunting and a mysterious illness drove its original inhabitants from the island two hundred years ago, making Tetepare today the largest uninhabited island in the tropical Pacific. The 120 square kilometer island (46 square miles), long untouched by industry or agriculture, is currently threatened by logging interests. However, the island is not without champions: in 2002 descendents of the original inhabitants of Tetepare formed the Tetepare Descendents Association (TDA) to preserve the island. Recently they have teamed up with the Solomon Islands Government and the Solomon Islands Community Conservation Partnership to develop financing through REDD.
Catastrophic sea level rise could occur with only two degrees Celsius warming
(12/17/2009) Allowing the climate to rise by just two degrees Celsius—the target most industrialized nations are currently discussing in Copenhagen—may still lead to a catastrophic sea level rise of six to nine meters, according to a new study in Nature. While this rise in sea levels would take hundreds of years to fully occur, inaction this century could lock the world into this fate.
Video: Octopus joins elite club of tool-users with coconut sanctuary
(12/15/2009) Highly-intelligent, octopuses have been observed opening containers, navigating mazes, and escaping from cages. Now, researchers have discovered a new intellectual feat for the octopus: tool use. Once the province of humans only, over the last 50 years researchers have discovered that many species—including primates, apes, and birds—employ tools, but the octopus is the first invertebrate.
Climate change causing irreversible acidification in world's oceans
(12/15/2009) A new study from the Secretariat of the Convention on Biological Diversity has synthesized over 300 reports on ocean acidification caused by climate change. The report finds that increasing acidification will lead to irreversible damage in the world's oceans, creating a less biodiverse marine environment. Released today the report determines that the threat to marine life by ocean acidification must be considered by policymakers at the UN Climate Change Conference in Copenhagen.
