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. 

Tuna are in trouble

Tuna is one of the world's favourite fish and a lot of industries are specialized in tuna's business. But there simply aren't enough fish to sustain the world's voracious appetite for tuna. Over-fishing and pirates stealing tuna are pushing the ocean to the brink of extinction.

Tuna are specially in serious trouble in the Western and Central Pacific Ocean. In 1999, Greenpeace noticed that tuna's population had declined by 80 percent in few years. And it's getting worse because advances in technology make easier the overfishing. Ships are now able to take as much tuna in 2 days as whole countries can take in a year.
To protect tuna from the industrialization, we need to create marine reserves. These areas will be closed to all extractive uses, such as fishing and mining. Marine reserves can help save tuna, ecosystems, and ultimately the fishing industry.
