WWF floated an 11 metre western gray whale down the River Thames this week, to highlight the plight faced by one of the world's most endangered whales.

With as few as 130 whales, the western gray whale teeters on the edge of extinction. Their critical feeding ground off the coast of Sakhalin Island in the Russian Far East, is now under threat. WWF is stepping in to try and help. You can help them too.
