Leonardo DiCaprio Protects Wild Tigers in India and Nepal

Follow @LeoDiCaprio on Twitter and you'll find the expected plugs for his J. Edgar movie. But more often, you'll see alarming news and urgings (with exclamation points!) about endangered tigers and other animals. DiCaprio's latest goal: to build support that will help double the number of wild tigers by 2022, the next Year of the Tiger. He's heading up World Wildlife Fund's Save Tigers Now campaign.

Go There: Travel to India and Nepal's tiger reserves and national parks. Tour income builds support among locals for protecting the tigers.

Get Involved: Join a WWF tiger safari in India and learn about protecting tiger habitats.
