The World Wildlife Fund is warning wild tigers could become extinct in 12 years if the animals are not protected. Only about 3,200 tigers remain in the wild, down from 100,000 a century ago. A global summit on saving the tiger opened Sunday in St. Petersburg, Russia.

World Bank President Robert Zoellick: “The tiger is what is referred to as an umbrella species. And what that means is if you save the tiger, you’re also going to have to save its prey populations and you’re going to have to preserve the biological diversity of its habitat. So by saving the tiger, you save a lot more than the tiger.”
