Shield America's Polar Bear Seas From Dangerous oil Drilling

Offshore oil drilling could soon jeopardize America's Arctic Ocean, a wild and wonderful place full of polar bears. An oil spill or industrial accident in these remote, icy waters would cause incredible harm and be almost impossible to contain or clean up — and oil drilling here would only deepen America's commitment to dirty fossil fuel. Learn about our long campaign to save polar bears and tell Obama to halt Arctic drilling.

A fracking boom in California would increase the state's earthquake danger, the Center and allies found in a new report. Learn how oil companies are raising California’s risk by annually injecting billions of gallons of wastewater into hundreds of disposal wells.
Killing Keystone XL
This 1,700-mile-long planned pipeline would move up to 35 million gallons of dirty tar-sands oil every day, plowing through species habitat and hastening climate change chaos. Help stop this environmental disaster now — before it’s too late.

Heading Toward 10 Billion People
