(07/21/2010) Corals aggregate to form vast reefs, which are home to numerous species and provide vital ecological services such as protecting shorelines. However, coral reefs are one of the most threatened ecosystems in the world due to many factors, such as global warming and ocean acidification. Recent research by Simpson and his team of scientists has shown that corals, rather than drifting aimlessly after being released by their parent colonies and by chance landing back on reefs, instead find their way purposefully to reefs by detecting the sound of snapping shrimps and grunting fish on the reef. However, that discovery also means that the larvae might struggle to find reefs when human noises, like drilling or boats, mask the natural ocean sounds.
(07/19/2010) As I discovered in the course of researching my book, No Rain in the Amazon: How South America’s Climate Change Affects the Entire Planet (Palgrave, 2010), the oil industry has had a poor record when it comes to protecting aquatic sea life. Take for example the manatee, which has been put at risk from the Amazon to the Gulf of Mexico as a result of the oil industry. One of the most outlandish creatures on the planet, the shy and retiring manatee, which gets its name from an American Indian word meaning “Lady of the Water,” was first described as a cross between a seal and hippo. The creature has a wonderfully round body, mostly black skin the texture of vinyl, a bright pink belly, a diamond-shaped tail and a cleft lip.
(07/11/2010) Most of the US's large ecosystems are but shadows of their former selves. The old-growth deciduous forests that once covered nearly all of the east and mid-west continental US are gone, reduced to a few fragmented patches that are still being lost. The tall grassy plains that once stretched further than any eye could see have been almost wholly replaced by agriculture and increasing suburbs. Habitats, from deserts to western forests, are largely carved by roads and under heavy impact from resource exploitation to invasive species. Coastal marine systems, once super abundant, have partially collapsed in many places due to overfishing, as well as pollution and development. Despite this, there are still places in the US where the 'wild' in wilderness remains largely true, and one of those is the Tongass temperate rainforest of Southeast Alaska.
(07/08/2010) According to a new analysis by the World Resources Institute (WRI), the many ecosystem services provided by the Gulf of Mexico will be severely impacted by BP's giant oil spill. 'Ecosystem services' are the name given by scientists and experts to free benefits provided by intact ecosystems, for example pollination or clean water. In the Gulf of Mexico, such environmental benefits maintain marine food production, storm buffers, tourism, and carbon sequestration, but one of the most important of marine ecosystem services is known as 'primary production'.
(07/05/2010) Imagine an ocean untouched by oil spills: a sea free of pollution, invasive species, dead zones, and over-exploitation; waters where marine animals exist in natural abundance and play ecological roles undimmed by mankind. Such a place may sound impossible in today's largely depleted oceans, but it exists: only discovered in 1841, the Ross Sea spreads over nearly a million kilometers adjacent to the Antarctic continent. Here killer whales, penguins, sea birds, whales, and giant fish all thrive. However, even with its status as the world's 'last ocean', the Ross Sea has not escaped human impact. Over the last 15 years commercial fisheries have begun to catch one of its most important species in the ecosystem to serve them up on the dinner plates of the wealthy.
(06/30/2010) On May 28th the parliament in Papua New Guinea passed a sweeping amendment that protects resource corporations from any litigation related to environmental destruction, labor laws, and landowner abuse. All issues related to the environment would now be decided by the government with no possibility of later lawsuits. Uniquely in the world, over 90 percent of land in Papua New Guinea is owned by clan or communally, not be the government. However this new amendment drastically undercuts Papua New Guinea's landowners from taking legislative action before or after environmental damage is done. Essentially it places all environmental safeguards with the Environment and Conservation Minister.
(06/23/2010) The International Whaling Commission (IWC), which was supposed to decide a way forward for whales over the next decade has ended without an agreement. Talks broke down, according to participants, because countries opposed to whaling and those that continue hunting and killing whales despite a ban on commercial whaling—i.e. Japan, Norway, and Iceland—have been unable to find enough common ground to pound out an agreement.
(06/13/2010) Local fishermen in the Malaysian state of Sabah are uncertain of their future, if the government pushes ahead to build a 300 megawatt coal power plant. They have been told they will be moved from their current seaside village to one deeper inland, and while the coal plant will provide manual labor work in its building stages, the fishermen express doubt about the impacts over the long-term effects of the coal plant on their livelihood. "Someone mentioned that maybe we have to move to Sungai Merah, which is quite far from our village. We are also worried because Sungai Merah is not next to the sea like [our village] is," local fishermen, Ali Hia, told Green SURF and Save Sandakan members—two local organizations opposed to the coal plant—who recently visited the seaside village of Kampung Sinakut, site of the proposed coal plant.
(06/10/2010) Everyone loves penguins. With their characteristic black-and-white 'tuxedo' markings, upright waddle, and childlike stature, penguins seem at once exotic and familiar: exotic because they live far from most human habitations, familiar because they appear in innumerable books and movies. From Mr. Popper's Penguins to Happy Feet, and from March of the Penguins to And Tango Makes Three, penguins pop-up everywhere. The flightless birds have even provided the name and symbol to one of the world's most successful publishing houses. Yet despite their popularity amid the human kingdom, few people seem aware that penguins worldwide are facing an extinction crisis.
(06/08/2010) Will we ever know the full wildlife toll of the BP oil spill? The short answer: no. The gruesome photos that are making the media rounds over the last week of oiled birds, fish, and crustaceans are according to experts only a small symbol of the ecological catastrophe that is likely occurring both in shallow and deep waters. Due to the photos, birds, especially the brown pelican, have become the symbol of the spill to date. But while dozens of birds have been brought to rescue stations covered in oil, the vast majority will die out at sea far from human eyes and snapping cameras, according to Sharon Taylor a vet with the US Fish and Wildlife Service.
(06/07/2010) Things have become ugly in the Mediterranean: over the weekend, fishermen and Greenpeace activists squared off over the fate of the Critically Endangered bluefin tuna. One run-in, in which Greenpeace worked to free tuna from fishermen's nets, left one activist in the hospital after a fisherman sunk a hook in the activist's leg. Meanwhile, the Sea Shepherd Conservation Society has announced a 'Blue Rage' campaign that will target illegal fishing of bluefin tuna.
(06/02/2010) Radical, controversial, ahead-of-his-time, brilliant, or extremist: call Dr. Glen Barry, the head of Ecological Internet, what you will, but there is no question that his environmental advocacy group has achieved major successes in the past years, even if many of these are below the radar of big conservation groups and mainstream media. "We tend to be a little different than many organizations in that we do take a deep ecology, or biocentric approach," Barry says of the organization he heads. "[Ecological Internet] is very, very concerned about the state of the planet. It is my analysis that we have passed the carrying capacity of the Earth, that in several matters we have crossed different ecosystem tipping points or are near doing so. And we really act with more urgency, and more ecological science, than I think the average campaign organization."
(05/23/2010) The International Institute for Species Exploration at Arizona State University has released its annual top 10 list of new species discovered last year. This time the list includes a two inch penis-like mushroom, a minnow named after Bram Stoker's world-famous horror-character, a bomb-throwing deep sea worm, a giant carnivorous plant named after TV personality and conservationist David Attenborough, and a beautifully patterned frogfish.
(05/21/2010) With the world's eyes on the environmental catastrophe in the Gulf of Mexico, many are beginning to ponder the rightness of not just America's, but the world's dependence on fossil fuels. Yet large-scale fossil-fuel energy projects continue to march ahead, including one in the Malaysian state of Sabah on Borneo to build a 300 MW coal plant, which has come under fierce opposition from locals (already the project has been forced to move locations twice). The newest proposal will build the coal plant, as photos below reveal, on an undeveloped beach overlooking the Coral Triangle, one of the world's most biodiverse marine environments, with transmission lines likely running through nearby pristine rainforest that are home to several endangered species, including orangutans and Bornean rhinos.
(05/13/2010) The oil spill in the Gulf of Mexico is taking its toll on the region's wildlife: brown pelicans, sea turtles, several species of fish, and now dolphins have been found dead. The National Marine Fisheries Service reported today finding six dead dolphins in Louisiana, Mississippi, and Alabama since May 2nd. Officials are saying the deaths could be related to the oil spill or may be due to natural deaths from calving. They are currently testing tissue samples to determine if oil pollution was a cause of death. Dolphins have been observed swimming in oil-stained waters off of Louisiana.
(05/04/2010) America, we deserve the oil spill now threatening the beautiful coast of Louisiana. This disaster is not natural, like the earthquake that devastated Haiti or tsunami that swept Southeast Asia in 2006; this disaster is man-made, American-made in fact, pure and simple. So, while in the upcoming weeks and months—if things go poorly—we may decry the oil-drenched wildlife, the economic loss for the region, the spoiled beeches, the wrecked ecosystems, the massive disaster that could take decades if not longer to recover from, we, as Americans, cannot think smugly that we are somehow innocent of what has happened. You play with fire: you will get burned. You drill for oil 1,500 meters below the surface of the ocean, you open up oil holes across the surface of your supposedly-beloved landscape, sooner or later there will be a spill, and sometimes that spill will be catastrophic.
(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?
(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.
(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.
(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.
(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.
(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.
