Take Action: Tell the President, no new oil spills, no new drilling.

"I think the environmental impact of this disaster is likely to be very, very modest," claimed BP Chief Executive Tony Hayward following last year's Deepwater Horizon disaster on April 20.

But in fact, "The spill here in the Gulf of Mexico is the worst environmental disaster in the history of our continent."

Greenpeace has been working with independent scientists from universities around the country to find out what has really happened to the oil, and what the long term impacts will be on this critical, fragile ecosystem.

Greenpeace's ship, the Arctic Sunrise, even spent three months in the Gulf to support independent scientists. Greenpeace's research team has also just procured thirty thousand documents on the spill from the federal government through the Freedom of Information Act and needs your help looking through them.
