In a Yale Environment 360 interview, the outspoken executive director of Greenpeace discusses why his organization’s activists braved imprisonment in Russia to stop Arctic oil drilling and what needs to be done to make a sharp turn away from fossil fuels and toward a green energy economy.

Even if reviving extinct species is practical, it’s an awful idea. It would take resources away from saving endangered species and their habitats and would divert us from the critical work needed to protect the planet.

A group led by futurist Stewart Brand is spearheading a movement to try to use genetic technology to revive extinct species, such as the woolly mammoth and the passenger pigeon. In a Yale Environment 360 debate, Brand makes the case for trying to bring back long-gone species, while biologist Paul R. Ehrlich argues that the idea is ill conceived and morally wrong.

With prominent scientists now calling for experiments to test whether pumping sulfates into the atmosphere could safely counteract global warming, critics worry that the world community may be moving a step closer to deploying this controversial technology.

As the world becomes more urbanized, researchers and city managers from Baltimore to Britain are recognizing the importance of providing urban habitat that can support biodiversity. It just may be the start of an urban wildlife movement.

University of Oregon law professor Mary Wood says environmental laws in the United States are simply not working. In an interview with Yale Environment 360, she explains why she believes a new strategy and robust judicial intervention are needed to protect nature and the climate.

In Borneo's Danum Valley — one of the last, untouched forest reserves in a region ravaged by logging and oil palm cultivation — a team of international and Malaysian scientists is fighting to preserve an area of stunning biodiversity.

Photographer Peter Essick has traveled the world documenting the causes and consequences of climate change. In a Yale Environment 360 photo essay, we present a gallery of images Essick took while on assignment in Antarctica, Greenland, and other far-flung locales.

By encouraging the adoption of innovative architectural design and energy-saving technologies, Singapore has emerged as a model of green building in Asia — an important development in a region that is urbanizing more rapidly than any other in the world.

Although coal has dominated the South African electricity sector for decades, the country’s abundant solar and wind resources offer a promising renewable energy alternative. But entrenched political interests connected to the ruling party are fighting to expand coal’s role in the national economy.

Large-scale solar projects are enjoying steady growth in California and the southwestern United States. But will shifting government incentives and mandates slow the expansion of this key part of the solar energy industry?

In an interview with Yale Environment 360, Robert Martin, co-author of a recent study on industrial farm animal production, explains how a powerful and intransigent agriculture lobby has successfully fought off attempts to reduce the harmful environmental and health impacts of mass livestock production.

A shortage of "rare earth" metals, used in everything from electric car batteries to solar panels to wind turbines, is hampering the growth of renewable energy technologies. Researchers are now working to find alternatives to these critical elements or better ways to recycle them.

After three decades of unbridled economic growth and mounting ecological problems, China and its new leadership face a key challenge: cleaning up the dirty air, polluted water, and tainted food supplies that are fueling widespread discontent among the country’s burgeoning middle class.

One year after Hurricane Sandy devastated parts of the U.S. East Coast, the government is spending billions to replenish beaches that will only be swallowed again by rising seas and future storms. It’s time to develop coastal policies that take into account new climate realities.

As Bangladesh makes a controversial turn to coal to produce electricity, the construction of a large coal-fired power plant is threatening the fragile ecosystem of the Sundarbans, the world’s largest mangrove forest.

The U.N. climate panel concluded last month that carbon emissions should be capped at a trillion tons, a total the world is rapidly approaching. Now comes the hard part: How will we decide how the remaining emissions are apportioned?

Traveling throughout China, from the Tibetan Plateau to the lush subtropical forests in the south, a photojournalist documents the vast scope of the country's environmental challenges.

With the dismantling of two dams on Washington state’s Elwha River, the world’s largest dam removal project is almost complete. Now, in one of the most extensive U.S. ecological restorations ever attempted, efforts are underway to revive one of the Pacific Northwest’s great salmon rivers.

As eel populations plummet worldwide, Japanese scientists are racing to solve a major challenge for aquaculture — how to replicate the life cycle of eels in captivity and commercially produce a fish that is a prized delicacy on Asian dinner tables.

With advances in genetic sequencing technology, scientists are now able to readily identify the microbes living in and around the roots of trees. This information is proving to have important implications for everything from tropical forest restoration to climate change planning.
