I'm very sorry to report that earlier today, Steve Irwin, the infamous "Crocodile Hunter", died owing to an unfortunate accident while diving on the Great Barrier Reef. A tireless campaigner for ecological issues, in particular the importance of protecting top predator species such as sharks and crocodiles, Steve was one of the great conservationists of the twentieth century. His television shows took millions of people into his unique world, showing hundreds of species in their natural habitats, demystifying what is usually sensationalised, and revealing the natural world in all its beauty and strangeness with an honest and distinctly human editorial touch that I have always admired. My sympathy goes out to his wife, Terri, and his two children. He will be missed.
