I can't quite come to grips with the public outpouring of grief over the death of "Crocodile Hunter" Steve Irwin. I heard a woman on the radio this morning who had driven from northern New South Wales with her children simply to be at South Bank's Suncorp Piazza to watch this morning's memorial service among like-minded people. As far as I could tell, she had never met Irwin but was simply a fan of his work. It's not something I would do and I wonder whether, in some cases at least, it's more about being a part of something than it is about Irwin himself. In any case, I hope that these people take a strong conservation message home with them today and start thinking, and doing something, about big issues like the destruction of habitat, desalination, pollution and climate change.
