China is responsible for a lot of the major conservation issues we're facing. It's the main market for rhino horn. Tigers are being killed for tiger bone wine. They're driving the tropical timber trade and illegal logging in Indonesia, and the trade in tropical reef fish.

The Galapagos Islands are probably the most famous wildlife-watching destination in the world. And no wonder - it's almost impossible to exaggerate the sheer spectacle of the place that provided inspiration for Charles Darwin's ground-breaking theory of natural selection.

Then, there was Greenpeace, I remember that when they first started out with the boats in the waters, and the guys in the boats between the whales and the boats that will hunting the whales with spear guns.
