Save whales

Whaling is no longer the only threat to whales. The human impacts on the oceans have changed dramatically over the half-century. 

Now environmental threats to whales include global warming, pollution, overfishing, ozone depletion, noise such as sonar weaponry, and ship strikes. Despite being protected, 7 of the 13 great whales are endangered or vulnerable. 

Fortunately, many associations try to defend whales. The principal solution would be to forbid whaling. 44 activists from Greenpeace appeal for help in their campaign to end whaling in the Southern Ocean Whale Sanctuary, by spelling out the words "Help End Whaling!" using their bodies.
