(04/18/2011) Analyzing the feathers of the black-footed albatross (Phoebastria nigripes) going back to 1880. researchers have uncovered rising levels of the toxic methylmercury in the endangered birds that is generally consistent with rising mercury emissions in the Pacific region. Methylmercury is a more toxic compound than mercury that binds with organic molecules when it is released through industrial processes, such as burning coal and other fossil fuels.
The great penguin rescue: far-flung community cooperates, sacrifices to save 4,000 penguins from oil spill
(04/18/2011) One of the world remotest communities, the UK's Tristan da Cunha archipelago, has come together to save 4,000 endangered penguins following a devastating oil spill, reports the Guardian. Last month a freighter ran aground on Nightingale Island releasing 1,500 tons of oil, potentially devastating the local population of northern rockhopper penguins (Eudyptes moseleyi), which are listed as Endangered by the IUCN Red List. However, fortunately for the penguins, the tiny community of 260 people living on the Tristan da Cunha archipelago were unwilling to give up on the oiled birds.
Gas from 'fracking' not climate friendly
(04/13/2011) It appears every time a fossil fuels industry claims its energy is 'green' or 'climate-friendly', scientists discover this just isn't so. The most recent culprit is natural gas produced by an already controversial method known as hydraulic fracturing, or fracing, which extracts the gas from shale basins. A new study in Climatic Change has found that the process of fracing is worse than coal over a 20-year period and about equal over 100-years. Coal had long been considered the worst climate offender of all energy options.
More biodiversity equals cleaner water, but why?
(04/07/2011) A new landmark study not only proves that adding more species to a freshwater stream linearly increases the ecosystem's ability to clean pollutants, but also shows why. The study, published in Nature found that by increasing the biodiversity of a lab controlled mini-stream from one algae species to eight caused the ecosystem to soak up nitrate pollution 4.5 times faster on average. To conduct the experiment, researchers used plastic to create 150 mini model streams. Molding the plastic, they recreated real stream-like habitats such as pools, runs, and eddies. Different species of algae gravitated toward particular mini-habitats, creating special ecological niches and allowing more of the stream to be utilized by the algae for soaking up the nitrate pollution. Less utilization of the available habitats resulted in a dirtier river and vice-versa.
The value of the little guy, an interview with Tyler Prize-winning entomologist May Berenbaum
(04/06/2011) May Berenbaum knows a thing or two about insects: in recognition of her lifelong work on the interactions between insects and plants, she has had a character on The X-Files named after her, received the Public Understanding of Science and Technology Award for her work in making science accessible to the public, and this year has been awarded the prestigious Tyler Environmental Prize. "Winning the Tyler Prize is an incredible honor—most of my scientific heroes have been Tyler Prize winners and I’m exceedingly grateful to be considered worthy of being included among their ranks," Berenbaum told mongabay.com in an interview. "The Prize is also tremendously enabling—because the money is unrestricted I can use it to carry out projects that have been difficult to fund."
New organization seeks to make biofuels sustainable, but is it possible?
(03/24/2011) Not too long ago policy-makers, scientists, and environmentalists saw biofuels as a significant tool to provide sustainable energy to the world. However, as it became clear that biofuels were not only connected to deforestation, pollution, and greenhouse gas emissions (sometimes exceeding fossil fuels), but also competed with the global food supply and water sources, biofuels no longer seemed like a silver bullet, but a new problem facing the environment and the poor. Still, biofuels have persisted not so much due to perceived environmental benefits, but to entrenched interests by the big agricultural industry, lobbyists, and governments. However, the Roundtable on Sustainable Biofuels (RSB) hopes to begin certifying environmentally friendly biofuels that don't compete with food production or water sources.
Photos: penguins devastated by oil spill
(03/22/2011) Disturbing photos show northern rockhopper penguins (Eudyptes moseleyi) hit hard by an oil spill from a wrecked cargo ship on Nightingale Island in the Southern Atlantic. Already listed as Endangered by the IUCN Red List, the oil spill threatens nearly half of the northern rockhopper population according to BirdLife International. Already conservation workers say 'hundreds' of penguins have been oiled. Located the remote Southern Atlantic, Nightingale Island is a part of the UK's Tristan da Cunha archipelago. The island's are home to a variety of birdlife, including species that survive no-where else but on the archipelago.
US approves first deepwater drilling in Gulf since BP disaster as oil tar balls reappear on coast
(03/22/2011) Yesterday the US Bureau of Ocean Energy Management, Regulation and Enforcement awarded Royal Dutch Shell PLC the first deep-water exploration permit since the BP disaster last year, which sent some 4.9 million barrels of oil and up to 500,000 tons of methane into the Gulf of Mexico over three months.
Hundreds of endangered penguins covered in oil after remote spill
(03/21/2011) Conservation workers have found hundreds of oiled northern rockhopper penguins (Eudyptes moseleyi) after a cargo vessel wrecked on Nightingale Island, apart of the UK's Tristan da Cunha archipelago. Northern rockhopper penguins are listed as Endangered by the IUCN Red List. According to a press release by BirdLife International, the spill threatens nearly half of the world's northern rockhopper population.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Green jeans: big companies start sustainable clothing initiative
(03/06/2011) Ever wonder how 'green' one pair of shoes was over another? Or how much energy, water, and chemicals went into making your pair of jeans? A new effort by over 32 companies, environmental organizations, and social watchdogs may soon allow shoppers to compare not only price and appeal, but sustainability too.
Report: 90 oil spills in Peruvian Amazon over 3 years
(03/03/2011) A new report has uncovered 90 oil spills by Pluspetrol in northern Peru's Amazon rainforest over the past 3 years. Covering two oil blocs—1-AB and 8—the report, complied by the Federation of Indigenous Communities of the Corrientes River (FECONACO), recorded 18 major oil spills in just the last year. "A week after the landmark ruling against Chevron in Ecuador for $9 billion of damage from operations in the 1970's and 80's, this new report highlights the ongoing devastation caused by the oil industry on the fragile Amazon ecosystem and the people that live there," said Atossa Soltani, Executive Director at Amazon Watch, in a press release.
Dead baby dolphins washing ashore in Gulf of Mexico
(02/28/2011) Every year a few baby dolphins in the Gulf don't make it and are found on the shores of the Gulf, but this year something is different. To date, 24 baby dolphins have been found dead in Alabama and Georgia, some are stillborn, others aborted fetuses. Researchers, who say death-toll is ten times the average, are currently studying the dead porpoises for clues to cause. These could include colder-than-average waters, algal blooms, disease, or the incident in the back of everyone's mind: the BP oil spill last year.
Coral crisis: 75% of the world's coral reefs in danger
(02/23/2011) Marine scientists have been warning for years that coral reefs, the most biodiverse ecosystems in the ocean, are facing grave peril. But a new comprehensive analysis by the World Resources Institute (WRI) along with twenty-five partners ups the ante, finding that 75% of the world's coral reefs are threatened by local and global impacts, including climate change. An updating of a 1996 report, the new analysis found that threats had increased on 30% of the world's reefs. Clearly conservation efforts during the past decade have failed to save reefs on a large-scale.
Photo gallery: Borneo paradise saved from beachside coal plant
(02/22/2011) Last week the Malaysian government announced it had canceled a plan to build a coal-fired plant in the state of Sabah. The coal plant would have rested on a beach overlooking the Coral Triangle, one of the ocean's most biodiverse ecosystems, and 20 kilometers from Tabin Wildlife Reserve, a rainforest park home to endangered orangutans, Sumatran rhinos, Bornean elephants, and thousands of other species. The cancellation followed a long campaign by a group of environmental and human right organizations dubbed Green SURF (Sabah Unite to Re-power the Future), which argued that the coal plant would have imperiled ecosystems, ended artisanal fishing in the area, hurt tourism, and tarnished Sabah's reputation as a clean-green state.
Kids found organization to save endangered species
(02/22/2011) Many American children under ten spend their free time watching TV and movies, playing video games, or participating in sports, but for siblings Carter (9 years old) and Olivia Ries (8) much of their time is devoted to saving the world's imperiled species. The organization One More Generation (OMG) not only has a clever name (yes, it is meant to pun the common Oh-My-God acronym), but may have the two youngest founders of an environmental organization in the US. "We started OMG because it hurt our hearts to know that there were so many animals in danger of becoming extinct," Carter told mongabay.com. OMG, which is run with help from the Ries' parents as well as an impressive list of conservation and wildlife experts, has taken on a number of local and international campaigns, including raising money for cheetahs, working against throw-away plastic bags, and taking action to change the US tradition of Rattlesnake Roundups where thousands of rattlesnakes are killed for a community festival.
Gulf of Mexico bottom still coated in oil, recovery long way off
(02/21/2011) Samantha Joye of the University of Georgia has seen the bottom of the Gulf of Mexico and the view wasn't pretty. Speaking at the American Association for the Advancement of Science, Joye told the conference that she found places where oil lay on the Gulf floor nearly 4 inches (10 centimeters) thick. Joye's findings contradict rosier pictures of the overall damage caused by the 2010 BP oil spill, including a recent statement by Kenneth Feinberg, the US government czar for oil compensation, that the Gulf would largely recover by next year.
First strike against illegal gold mining in Peru: military destroys miners' boats
(02/21/2011) Around a thousand Peruvian soldiers and police officers destroyed seven and seized thirteen boats used by illegal gold miners in the Peruvian Amazon, reports the AFP. The move is seen as a first strike against the environmentally destructive mining. Used to pump silt up from the river-bed, the boats are essential tools of the illegal gold mining trade which is booming in parts of the Amazon.
Coal's true cost in the US: up to half a trillion
(02/20/2011) According to the global market coal is cheap, yet a new study in the Annals of the New York Academy of Sciences finds that the hidden costs of coal are expensive, very expensive. Estimating the hidden costs of coal, such as health and environmental impacts, the study found that burning coal costs the US up to $523 billion a year. Dubbed 'externalities' by economists, the paper argues that these costs are paid by the American public to the tune of $1,698 per person every year.
Worldwide search for 'lost frogs' ends with 4% success, but some surprises
(02/16/2011) Last August, a group of conservation agencies launched the Search for Lost Frogs, which employed 126 researchers to scour 21 countries for 100 amphibian species, some of which have not been seen for decades. After five months, expeditions found 4 amphibians out of the 100 targets, highlighting the likelihood that most of the remaining species are in fact extinct; however the global expedition also uncovered some happy surprises. Amphibians have been devastated over the last few decades; highly sensitive to environmental impacts, species have been hard hit by deforestation, habitat loss, pollution, agricultural chemicals, overexploitation for food, climate change, and a devastating fungal disease, chytridiomycosis. Researchers say that in the past 30 years, its likely 120 amphibians have been lost forever.
Environmentalists and locals win fight against coal plant in Borneo
(02/16/2011) Environmentalists, scientists, and locals have won the battle against a controversial coal plant in the Malaysian state of Sabah in northern Borneo. The State and Federal government announced today that they would "pursue other alternative sources of energy, namely gas, to meet Sabah's power supply needs." Proposed for an undeveloped beach on the north-eastern coast of Borneo, critics said the coal plant would have threatened the Coral Triangle, one of the world's most biodiverse marine ecosystems, and Tabin Wildlife Reserve, home to Critically Endangered Sumatran rhinos and Bornean orangutans. Local fishermen feared that discharges from the plant would have imperiled their livelihood.
Chevron found guilty, ordered to pay $8.2 billion in epic oil contamination fight
(02/14/2011) It was the environmental legal battle that some believed would never end (and they may still be right). But today in Lago Agrio, Ecuador, after 18 years of an often-dramatic court case, Chevron was found guilty of environmental harm and ordered to pay $8.2 billion in damages, however the oil giant says it will appeal the ruling. The lawsuit was filed by indigenous groups in the Ecuadorian Amazon who argue that poor environmental safeguards from Texaco in the 1970s and 80s led to widespread oil contamination and high rates of diseases, including cancer, among the populace. In 2001 Chevron purchased Texaco and inherited the legal fight. For its part, Chevron has dubbed the ruling "illegitimate" and with an appeal will drag the case on longer.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Is Obama's clean energy revolution possible?
(01/26/2011) Last night US President Barack Obama called for a massive green energy make-over of the world's largest economy. Describing the challenge as 'this generation's Sputnik moment' the US president set a goal of producing 80 percent of America's energy by clean sources by 2035. While this may sound improbable, two recent analyses back the president up, arguing that a global clean energy revolution is entirely possible within a few decades using contemporary technology and without breaking the bank. "Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources," Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford said in a press release. "It is a question of whether we have the societal and political will."
Marathon swimmer: an interview with the first man to swim the length of the Amazon
(01/23/2011) Explorers have been making their way down the world's mightiest river for hundreds of years. Untold numbers of people have not completed the journey, drowning in its murky waters, being eaten by animals, losing their way, succumbing to tropical disease, being killed by pirates or hostile local populations. But today a trip down the Amazon is less special—it has even been rafted and kayaked by a few intrepid souls. Traversing the majority of the Amazon can be done easily by commercial boat, provided you have the time and a lot of patience. But then in 2007 a Slovenian did something amazing: he swam the entire length of the river. The adventure took 66 days and exacted a heavy physical and mental toll, but Martin Strel survived and in so doing conveyed a simple, but powerful message to the world: we are part of the our environment.
Australia's floods threaten Great Barrier Reef
(01/18/2011) The floods ransacking the Queensland coast have cost 20 lives and $500 million worth of property damage. Now, huge volumes of water are pouring into the ocean, threatening the Great Barrier Reef, which extends for thousands of kilometers off the coast. Although it may take years to know the full consequences of the flooding, Australian scientists are already warning of serious damage. For now, the biggest problems are concentrated on the southern part of the reef, where three overflowing rivers—the Burdekin, the Fitzroy, and the Burnett—have released millions of gallons of heavily polluted water into the sea. So far, prevailing winds have confined the majority of the floodwaters to within 65 kilometers of shore. But in time, the damage may grow to affect the entire reef system.
New Zealand: Can you sink a rainbow?
(01/12/2011) In a world wracked by Cold War, New Zealand’s Prime Minister, David Lange defends the country’s fledgling nuclear free policy by refusing the nuclear warship USS Buchanan’s entry into New Zealand’s shores. A historic day. He had received an almost unprecedented standing ovation at the Oxford Union Debate four months earlier where he had successfully argued the proposition that "nuclear weapons are morally indefensible". He was held high in the estimations of dedicated environmental group, Greenpeace for doing this, who were also fighting for the cease of nuclear testing and for New Zealand to be a leader in environmental protection. In addition, he was respected by his country for his bold stand.
Leatherback sea turtles tracked for first time in South Atlantic
(01/07/2011) Leatherback sea turtles undertake one of the longest journeys of any animal as they traverse the oceans in search of food, navigating hazards such as plastic pollution and fishing operations. A new study published in the Royal Society Journal Proceedings B has for the first time mapped their odyssey through the South Atlantic.
Renewed conflict between tribes and oil companies looms in Peru
(01/06/2011) Indigenous peoples and their allies have intensified their fight against two oil companies over contamination in the Peruvian Amazon. Last week, a group of indigenous protesters blockaded portions of the Marañon and Corrientes Rivers in the province of Loreto in northeastern Peru. The protesters were demanding that Pluspetrol, an Argentinean oil company, compensate them for a recent oil spill. As of December 28th, after eight days, the blockade remained unbroken.
Mediterranean Sea may be polluted with 250 billion microplastics
(01/05/2011) The 2010 scientific expedition undertaken by the European program called Mediterranean En-Dangered (MED) reveals that 250 billion microplastics could be found in the Mediterranean Sea. The main goal of the program, which will end in 2013, is to quantify the distribution of plastic pollution and better understand its dynamics in the Mediterranean Sea. Microplastics are usually defined as plastic particles smaller than 5 millimeters, so for most part they are invisible to human eyes.
Malaysia undermines commitment to protect Coral Triangle, backtracks on climate pledge
(12/22/2010) The Malaysian government will proceed with a plan to install a second-hand coal plant from China on the edge of the Coral Triangle in Borneo despite widespread condemnation from environmental groups and local people, reports Green SURF, a coalition that opposes the project.
Top 10 Environmental Stories of 2010
(12/20/2010) Below is a quick review of some of the biggest environmental stories of 2010: Climate change rears it ugly head; Oil spill in the Gulf; Agreement to save global biodiversity; Illegal logging crisis in Madagascar; REDD kicks off in Indonesia; Brazil deforestation falls to its lowest level; Hungary's red sludge; Nestle caves to social media activists; New mammals galore' and Global climate framework back on the table?
Will dumping mining waste in peatlands help mitigate climate change?
(12/02/2010) Indonesia's national climate change strategy document includes text suggesting that dumping mining waste in peatlands could be used as an approach to reducing greenhouse gas emissions.
Bacteria deep in the Gulf of Mexico consumed oil faster than expected, study finds
(11/15/2010) BP’s disastrous oil spill in the Gulf of Mexico this year killed countless marine animals, but it was a boon for oil-eating bacteria. The organisms, usually quiescent deep in the ocean, burst into life when the Deep Water Horizon wellhead ruptured and released a torrent of their favorite food. A study published in the 8 October issue of Science demonstrated how quickly bacteria consumed the light crude oil.
Nuclear power plant in a national park? Japanese NGOs seek international help
(11/14/2010) Despite pledging broad support for conservation in developing countries at the recent COP10 biodiversity summit, this year’s host Japan may be neglecting conservation issues closer to home.
Beyond gloom: solutions to the global coral reef decline
(11/10/2010) The world's coral reefs are in trouble. Due to a variety of factors—including ocean acidification, warming temperatures from climate change, overfishing, and pollution—coral cover has decline by approximately 125,000 square kilometers in the past 50 or so years. This has caused some marine biologists, like Charlie Veron, Former Chief Scientist of the Australian Institute of Marine Science, to predict that coral reefs will be largely extinguished within a century. This year alone, large-scale coral bleaching events, whereby coral lose their symbiotic protozoa and become prone to disease and mortality, were seen off the coasts of Indonesia, the Philippines, and some Caribbean islands. However a new paper in Trends in Ecology and Evolution attempts to dispel the gloom over coral reefs by pointing to strategies, and even some successes, to save them.
US elects barrage of climate change deniers, threatening support for green energy
(11/03/2010) The US midterm election, which won Republicans the House but safeguarded the Senate for Democrats, has brought in a number of self-proclaimed climate change deniers, ending any likelihood that an energy bill will be passed over the next two years and essentially stumbling the White House's strategy on climate change. Newly elected Republican Senators Rand Paul of Kentucky and Marc Rubio of Florida, both members of the nascent Tea Party, have stated they do not believe in climate change despite that scientists overwhelming agree the Earth is warming due to human impacts.
Japanese making themselves sick with dolphin hunt
(11/01/2010) Japan's dolphin hunt of Dall's porpoise (Phocoenoides dalli) could be making people sick, according to a new study by the Environmental Investigation Agency (EIA) and Campaign Whale. The controversial hunt, which kills some 15,000 dolphins annually, produces cheap meat-for-consumption that on average contains over double Japan's limit on mercury contamination. "We are very concerned that people in Japan are threatening their health and possibly that of their children by unwittingly eating Dall’s porpoise meat that is dangerously contaminated with poisons such as mercury and PCBs," Andy Ottaway, Director of Campaign Whale, said in a press release.
Island nation announces Ukraine-sized sanctuary for whales and dolphins
(10/24/2010) Dolphins, whales, and dugongs will be safe from hunting in the waters surrounding the Pacific nation of Palau. At the Convention on Biological Diversity (CBD) in Nagoya, Japan, Palau's Minister of the Environment, Natural Resources and Tourism, Harry Fritz, announced the establishment of a marine mammal sanctuary covering over 230,000 square miles (60,000 square kilometers) of the nation's waters, an area the size of Mongolia.
Space tourism will worsen climate change
(10/24/2010) Have $200,000 to spend on a seat into space? You may want to re-think the expenditure given a new study in Geophysical Research Letters that shows space tourism will likely aggravate global climate change. Using sophisticated modeling, the researchers found that the biggest impact of a rise in space tourism on global temperatures won't be due to carbon emissions, but black carbon, often in the form of soot.
Already Critically Endangered, bluefin tuna hit hard by BP oil disaster
(10/19/2010) Using satellite data from the European Space Agency, researchers estimate that over 20% of juvenile Atlantic bluefin tuna in the Gulf of Mexico were killed by the BP oil spill. Although that percentage may not seem catastrophic, the losses are on top of an 82% decline in the overall population over the past three decades due to overfishing. The population plunge has pushed the International Union for the Conservation of Nature (IUCN) to categorize the fish as Critically Endangered, its highest rating before extinction.
Humanity consuming the Earth: by 2030 we'll need two planets
(10/13/2010) Too many people consuming too much is depleting the world's natural resources faster than they are replenished, imperiling not only the world's species but risking the well-being of human societies, according to a new massive study by the World Wildlife Fund (WWF), entitled the Living Planet Report. The report finds that humanity is currently consuming the equivalent of 1.5 planet Earths every year for its activities. This overconsumption has caused biodiversity—in this case, representative populations of vertebrate animals—to fall by 30 percent worldwide since 1970. The situation is more dire in tropical regions where terrestrial species' populations have fallen by 60 percent and freshwater species by 70 percent.
Farms in the sky, an interview with Dickson Despommier
(10/12/2010) To solve today's environmental crises—climate change, deforestation, mass extinction, and marine degradation—while feeding a growing population (on its way to 9 billion) will require not only thinking outside the box, but a "new box altogether" according to Dr. Dickson Despommier, author of the new book, The Vertical Farm. Exciting policy-makers and environmentalists, Despommier's bold idea for skyscrapers devoted to agriculture is certainly thinking outside the box.
Citizens of 188 countries challenge leaders on climate change
(10/11/2010) As world leaders continue to fumble a coherent, rapid, and comprehensive response to climate change, citizens from around the world yesterday sent a message to inert politicians by participating in over 7,300 events against climate change, according to 350.org, the head organizer of the day dubbed the 'Global Work Party'. "The fossil fuel industry may have thought that the collapse of the Copenhagen talks and its victory in the U.S. Congress were the final word—that people would give up in discouragement," said, Bill McKibben, founder of 350.org, so-called because 350 parts per millions (ppm) is the 'safe' amount of carbon in the atmosphere according to many scientists. Currently the concentration is around 390 ppm.
Hungary suffers 'ecological tragedy' as aluminum mining sludge reaches Danube
(10/07/2010) Toxic red sludge, a waste product of aluminum production, has reached Europe's Danube River after a spill at a Hungarian factory drowned four people and left over a hundred injured, many with chemical burns. The Hungarian Academy of Sciences says tests show that heavy metals in the Danube due to the spill are currently far from dangerous levels, however other rivers, villages, and farmlands have been devastated by the environmental disaster which released approximately a million cubic meters of sludge over 50 square kilometers.
Rivers worldwide in peril: society treats symptoms, ignores causes
(09/29/2010) Dams, agricultural runoff, pesticides, sewage, mercury pollution from coal plants, invasive species, overconsumption, irrigation, erosion from deforestation, wetland destruction, overfishing, aquaculture: it's clear that the world's rivers are facing a barrage of unprecedented impacts from humans, but just how bad is the situation? A new global analysis of the world's rivers is not comforting: the comprehensive report, published in Nature, finds that our waterways are in a deep crisis which bridges the gap between developing nations and the wealthy west. According to the study, while societies spend billions treating the symptoms of widespread river degradation, they are still failing to address the causes, imperiling both human populations and freshwater biodiversity.
Cold snap may have killed millions of fish in Bolivia, poisoning rivers
(08/31/2010) Although the last few months have been some of the warmest worldwide on record, including 17 countries reaching or breaking all-time highs, temperatures have not been above average everywhere. Cold air from Antarctica has brought chilling temperatures to parts of South America, including Bolivia where millions of fish and thousands of caimans, turtles, and river dolphins have perished according to Nature Communications.
Coral reef survival depends on the super small, an interview with Forest Rohwer
(08/30/2010) If you take a teaspoon and dip it into the ocean what will you have? Some drops of lifeless water? Only a few decades ago this is what scientists would have said, however, the development of increasingly powerful microscopes have shown us a world long unknown, which has vital importance for the survival of one of the world's most threatened and most treasured ecosystems: coral reefs. A single milliliter of water is now known to contain at least a million living microbes, i.e. organisms too small to see without a microscope. After discovering their super-abundant presence, researchers are now beginning to uncover how these incredibly tiny life-forms shape the fate of the world's coral reefs.
A slow comeback for the endangered Eurasian otter in France
(08/29/2010) In the late 1970s, the fate of the Eurasian Otter (Lutra lutra) in France was very gloomy. By just looking at the otter's range map, one could see that most of the country was left with vast regions devoid of a species that was once found in every region. Estimations barely reached 1,500 otters left in the wild for the whole country. Today, 2,000 to 3,000 individuals are believed to room in creeks and rivers mostly in the Massif Central, the Atlantic side (Bretagne) and western area, in particular in the wetland of Poitevin. The upward trend in population size is good news and a step towards reconstituting sustainable populations, however, the overall population is still critically low. By contrast, in the early 1900s otters were quite abundant in France with over 50,000 wild animals.
Allegations abound: are nepotism and corruption behind the Sabah coal plant?
(08/25/2010) Allegations of government corruption and corporate kick-backs are swirling around a planned 300 MW Chinese coal plant in the Malaysian state of Sabah. While the plan to build the coal plant in Lahad Datu Bay has come up against strong and unrelenting grassroots opposition, the federal government continues to turn a deaf ear to opposition, arguing that the energy plant is necessary to power Sabah and stop blackouts. However, critics say the coal plant—which is to be built on the edge of the Coral Triangle and 20 kilometers from Tabin Wildlife Reserve—will damage fish stocks with chlorine and thermal discharges, upend the lives of locals dependent on fishing, and devastate eco-tourism in the region. In addition, the coal plant goes directly against Prime Minister Najib Tun Razak's agreement at Copenhagen to reduce the country's carbon emission intensity by 40 percent by 2020.
