Environmental questions about Canada’s massive tar sands development have long centered on greenhouse gas emissions. Now there are mounting concerns about the huge volumes of water used by the oil industry and the impact on the vast Mackenzie River Basin.

In one of China’s most biodiverse regions, the spread of rubber plantations to supply the country’s burgeoning automobile industry is carving up habitat and harming watersheds and tropical forest ecosystems.

German scientist Anders Levermann and his colleagues have released research that warns of major sea level increases far into the future. In an interview with Yale Environment 360, he raises important questions about how much we really care about the world we will leave to those who come after us.

President Obama has unveiled a proposal to combat global warming that would, for the first time, regulate carbon dioxide emissions from all U.S. coal-fired power plants. Yale Environment 360 asked a group of experts to assess the president’s climate strategy.

Vietnam has become one of the world’s leading rice producers, thanks to the construction of an elaborate network of dikes and irrigation canals. But these extensive infrastructure projects in the storied Mekong Delta have come at a high ecological price.

An estimated 30 million fish and other creatures are caught annually to supply the home aquarium market, taking a toll on some reef ecosystems. Now conservationists are working to improve the industry by ending destructive practices and encouraging aquaculture.

A marine biologist traveled to southwestern Alaska in search of ocean trash that had washed up along a magnificent coast rich in fish, birds, and other wildlife. He and his colleagues found plenty of trash -- as much as a ton of garbage per mile on some beaches.

Scientists studying a prolonged and severe drought in the southwestern U.S. say that extensive damage done to trees in that region portends what lies in store as other forests worldwide face rising temperatures, diminished rainfall, and devastating fires.

The development-at-any-cost policies of Turkish Prime Minister Recip Tayyip Erdogan — a key factor behind the protests and clashes in Istanbul’s Taksim Square — are also playing a role in the steady decline of the nation’s porpoises, dolphins, and other marine life.

Recent studies show that many of the world’s savannas, including famed southern African landscapes, are experiencing significant change as rising levels of carbon dioxide in the atmosphere favor the growth of trees over grasslands.

From northern Europe to Florida, highway planners are rethinking roadsides as potential habitat for native plants and wildlife. Scientists say this new approach could provide a useful tool in fostering biodiversity.

Scientists are predicting that warming conditions will bring more frequent and more intense extreme weather events. Their warnings hit home in densely populated Bangladesh, which historically has been hit by devastating sea surges and cyclones.

China’s recent admission to the Arctic Council under observer status reflects a new reality: the world’s economic powers now regard development of natural resources and commerce in an increasingly ice-free Arctic as a top priority.

A giant new hydro project on the Congo River is only the latest in a rush of massive dams being built across Africa. Critics contend small-scale renewable energy projects would be a far more effective way of bringing power to the hundreds of millions of Africans still without electricity.

Improvements in DNA technology now make it possible for biologists to identify every living organism in and around a species. Scientists say this could have profound implications for everything from protecting amphibians from a deadly fungus to reintroducing species into the wild.

Illegal logging and unchecked economic development are taking a devastating toll on the forests of Vietnam and neighboring countries, threatening areas of biodiversity so rich that 1,700 species have been discovered in the last 15 years alone.

In the wake of the 2011 tsunami, the Japanese government is forgoing an opportunity to sustainably protect its coastline and is instead building towering concrete seawalls and other defenses that environmentalists say will inflict serious damage on coastal ecosystems.

Climate scientist Ralph Keeling has followed in the footsteps of his father, who pioneered the measurement of carbon dioxide in the atmosphere. In an interview with Yale Environment 360, the younger Keeling talks about the implications of crossing an alarming CO2 threshold this month.

The California condor, the largest bird in North America, was saved from extinction by a captive breeding program that increased its numbers in the wild. But now the condor is facing a new and pernicious threat — the lead from bullets used by game hunters.

In a Swedish fjord, European researchers are conducting an ambitious experiment aimed at better understanding how ocean acidification will affect marine life. Ultimately, these scientists hope to determine which species might win and which might lose in a more acidic ocean.

In an online debate for Yale Environment 360, Elliot Entis, whose company has created a genetically modified salmon that may soon be for sale in the U.S., discusses the environmental and health impacts of this controversial technology with author Paul Greenberg, a critic of GM fish.
