I thought it was Australia where nature tries to kill you.
Both - Arizona has poisonous lizards that look like beaded hand bag fabric....same desert extends into parts of New Mexico, Texas, and Mexico.
Florida has nature that tries to kills you too. Off the top of my head, we've got gators, pygmy rattlesnakes, Eastern Diamond back rattlesnakes, coral snakes, water moccasins, pit vipers, scorpions, fire ants, black widow spiders, brown recluse spiders, stingrays, stone fish, jellyfish, lionfish, scorpionfish, stonefish, man-o-wars, bees/wasps/hornets, a variety of sharks, and a multitude of nasty stinging caterpillars. Not to mention tornadoes, sink holes, tropical storms, and hurricanes.
I'm sure I've missed some things, but this gives you an idea.
