Britain’s new government is proposing radically new energy policies, with a “Green Deal” that would retrofit the country’s woefully energy-inefficient housing stock. In an interview with Yale Environment 360, UK Energy and Climate Minister Greg Barker talks about why an overhaul of the approach to energy is essential for the nation’s future.

With large swaths of forest destroyed by wartime defoliants, and even larger areas lost to post-war logging, Vietnam has set an ambitious goal for regenerating its woodlands. But proponents of reintroducing native tree species face resistance from a timber industry that favors fast-growing exotics like acacia.

As climate science advances, predictions about the extent of future warming and its effects are likely to become less — not more — precise. That may make it more difficult to convince the public of the reality of climate change, but it hardly diminishes the urgency of taking action.

Last spring, conservation groups and timber companies signed an historic agreement to protect a large swath of Canada’s boreal forest. In an interview with Yale Environment 360, the Pew Environment Group's Steven E. Kallick, a key player in the agreement, explains why the accord is integral to a larger plan to eventually preserve half of Canada’s extensive boreal forests.

When officials gather for an international summit on biodiversity next month, they might look to remind the world why species matter to humans: for producing oxygen, finding new drugs, making agricultural crops more productive, and something far less tangible — a sense of wonder.

In the early 20th century, Russian botanist Nikolai Vavilov created a preserve outside St. Petersburg that today contains one of the world’s largest collections of rare seeds and crops. Now, scientists and conservationists are waging an international campaign to save the reserve’s fields from being bulldozed for housing development.

The freshwater eel, which spawns in the middle of the ocean, was once abundant in much of the world. But the proliferation of dams, coastal development, and overfishing have drastically reduced eel populations, with few defenders coming to the aid of these fascinating — though still not fully understood — creatures.

Earlier this year, 38-year-old environmental activist Michael Brune was named the unlikely choice to take over as head of the Sierra Club, the largest U.S. conservation organization. In an interview with Yale Environment 360, Brune says it’s time to move beyond overly accommodating strategies like those that failed to win passage of U.S. climate legislation.

The Gulf of Mexico’s capacity to recover from previous environmental assaults — especially the 1979 Ixtoc explosion — provides encouragement about the prospects for its post-Deepwater future. But scientists remain worried about the BP spill's long-term effects on the health of the Gulf and its sea life.

Primatologist Patricia Wright has spent the past 25 years studying — and protecting — Madagascar’s rich yet highly threatened biodiversity. Now, as many of the island’s remaining forests are being felled in the wake of a 2009 coup, Wright describes how she is helping organize the local residents and international conservation organizations to fight back.

Large corporations, not small-scale farmers, are now the major forces behind the destruction of the world’s tropical forests. From the Amazon to Madagascar, activists have been directing their actions at these companies — so far with limited success.

The images of pelicans and other Gulf of Mexico seabirds drenched in oil have stirred sadness and outrage around the world. But, says conservationist Melanie Driscoll, the unseen effects are probably far greater, with some birds perishing out of sight, far from shore, and others facing spill-related declines in the fish on which they depend.

The massive oil spill in the Gulf of Mexico is a warning, conservationists say, of what could happen in the Arctic as melting sea ice opens the Arctic Ocean to oil and gas drilling. Many experts argue that the time has come to adopt an Arctic Treaty similar to the one that has safeguarded Antarctica for half a century.

For years, free-market fundamentalists opposed to government regulation have sought to create doubt in the public’s mind about the dangers of smoking, acid rain, and ozone depletion. Now they have turned those same tactics on the issue of global warming and on climate scientists, with significant success.

A prominent marine biologist says the impacts of the oil gushing into the Gulf of Mexico will persist for years, no matter when the flow finally stops. What’s more, scientist Thomas Shirley says that most of the damage remains out of sight below the surface, as creatures succumb to the toxic effects of the rapidly spreading tide of oil.

The oil slick spreading across the Gulf of Mexico has shattered the notion that offshore drilling had become safe. A close look at the accident shows that lax federal oversight, complacency by BP and the other companies involved, and the complexities of drilling a mile deep all combined to create the perfect environmental storm.

Among the natural treasures at risk from the oil spill in the Gulf of Mexico is the Breton National Wildlife Refuge, created by Theodore Roosevelt to halt a grave threat to birds in his era — the lucrative trade in plumage. Now, oil from the BP spill is starting to wash up on beaches where Roosevelt once walked.

The chairman of the Intergovernmental Panel on Climate Change acknowledges it has been a rough few months for his organization. But, he argues, no amount of obfuscation and attacks by conspiracy theorists will alter the basic facts — global warming is real and intensifying.

With nearly $800 billion in drugs sold worldwide, pharmaceuticals are increasingly being released into the environment. The “green pharmacy” movement seeks to reduce the ecological impact of these drugs, which have caused mass bird die-offs and spawned antibiotic-resistant pathogens.

This April marks the 40th anniversary of Earth Day, an event that has attracted millions to environmental causes. But winning passage of meaningful legislation on climate change requires more than slogans and green talk — it demands intense, determined political action.

Once, on both sides of the Atlantic, fish such as salmon, eels, and, shad were abundant and played an important role in society, feeding millions and providing a livelihood for tens of thousands. But as these fish have steadily dwindled, humans have lost sight of their significance, with each generation accepting a diminished environment as the new norm.
