Polar bears are under threat from climate change. They depend on sea ice for feeding, and as the Arctic shrinks they are forced to move to solid ground where food is scarcer.

Big oil companies -- who have played a major part in causing climate change -- are now ready to take advantage of the retreating sea ice. They want to start drilling in the Arctic for oil, putting the polar bears' fragile habitat at even greater risk.

We need to keep drilling out of the Arctic and protect the polar bears' home. We must pressure our political leaders to protect the Arctic.

Your name will be added to a scroll we'll place on the sea bed at the North Pole together with a flag for the future to demand the Arctic is declared off limits to oil drilling and industrial fishing.
