BP will be messing up Australia next

The Great Australian Bight has all of the hallmarks of a place you really don't want to mess with — incredible marine diversity, endangered whales, awesome natural beauty.

How to save rhinos and tigers: Shoot the crap out of poachers

In India's Kaziranga National Park, rhinos and tigers are thriving, because poachers are dying instead. When it comes to poachers, the park's rangers have a license to kill, and they do. It gets results:

In 2010, only five rhinos were shot in Kaziranga, while nine poachers were killed, the first time poacher deaths surpassed rhinos. (For comparison, in South Africa, where rangers fire only in self-­defense, five poachers were killed in 2010, while 333 rhinos were poached.)

These guys were breaking the law and killing endangered species. But the moral calculus here isn't so clear-cut. In the park's region, jobs are scarce. Park animals eats crops and kill farm animals, and poaching pays better than any other pursuit. Shooting poachers on sight is apparently the most effective way to conserve the park’s threatened animals, but how does that stack up against human injustice? It’s a complicated calculation.
