The Crocodile Hunter is dead. Killed by a sting ray. It is fitting though, that he died doing what he loved. He seemed like the kind of guy who would be miserable decaying in an old folks home. Though he probably would have preferred being kill by a croc.
The world needs charismatic and energetic crusaders for the environment. Steve Irwin was able to capture people's attention with his shenanigans, and he used the time he had to educate everyone as to the fragile state of the wild.
