i will say something on a larger scale. i watch the shows on the science channels and it sickens me to see these crocodile hunter type guys (and theres a bunch of them now) preaching that we need things like poison snakes, crocodiles, killer bees. i just dont think we need them in great numbers in any highly populated areas. if you watch these type shows all they really do is harrass animals. they catch them show them off and then release them. i saw a show yesterday with that Oshea guy ( who i like) trying to save snakes on an island where hundreds are killed every year because of there bite. WE ARE TOP PREDATOR AND DONT NEED THESE ANCIENT EXTREME KILLING LIFE FORMS TO COMPETE WITH. since we are top of the food chain i dont think there is much need to worry about sharks when we eat all the tuna anyway. life is evolving and changing.
