I stopped watching the show because it became too absurd, most likely from studio pressure. However, despite David Letterman's retarded comments and Irwin's involvement in pop stardom(that horrid movie, had to watch it with some kids), I always admired his desire to show truth, but also to go out of his way, even putting himself in even more potential danger, to not interfere with the workings of nature, but instead to educate. He understood he did not command the world around him, just as a Professor commands his class but not his subject. One thing he always promoted,and practiced, on his show was that nature was not simply scenery, it was a beautiful thing to be given space, time, and most of all, respect. Its too bad so many americans thought that was "stupid".
