Jeff Corwin

Crikey, mates, look who's chasing crocs! No, not Steve Irwin, that Aussie bloke who hosts "The Crocodile Hunter." It's Jeff Corwin, that American dude who hosts "The Jeff Corwin Experience" on Animal Planet.

There is a holocaust happening. Right now. And it's not confined to one nation or even one region. It is a global crisis. Species are going extinct en masse. Every 20 minutes we lose an animal species. If this rate continues, by century's end, 50% of all living species will be gone. It is a phenomenon known as the sixth extinction. The fifth extinction took place 65 million years ago when a meteor smashed into the Earth, killing off the dinosaurs and many other species and opening the door for the rise of mammals.
