A lot of people have spoken of the diseases that can affect native populations. If you lived near a stream or river or pond growing up, didn't you catch animals? In my neighborhood, we would bike to bodies of water and try and catch whatever we could in our nets. We kept darters, madtoms, bluegill, sunfish, minnows, turtles, snakes (man, would those northern water snakes chew on you or what!?) and anything else small we could fit in an aquarium. After observing them, learning about them, seeing what they would eat, and generally developing an appreciation for them we would release them to free up room for something else. How many thousands, if not millions, of kids have done this in the past and are doing it now? Our wildlife populations are doing fine. Disease has not ravaged the bluegill population here in Ohio. The snapping turtle I fed guppies to has not decimated the snapping turtle population. If anything, I see more snapping turtles today than I remember as a kid. Based on some of the views here, there should be no animals left in the wild. They should have all been wiped out by disease. I understand your intentions, but if we had it your way, there would be little of what I had done as a kid. I would have had to kill each animal I caught. And frankly, you will not get a ten year old boy to kill a 2 inch snapping turtle he's kept for a pet for a year. He will bike to a pond and release it, regardless of what law he has broken. How do you stop that?
