When I was about 11, my father went down to Florida on some sort of Army business, and he brought me back a children's novel called "Swampy & Babs In Okefenokee." It was about two kids who witness poachers in the swamp and have to escape to report them and stop the killing of the animals. It was pretty darn good! And looking back, I realize it had a lot to do with shaping my attitudes about animals and the ecology.
