Growing up here in S. Florida, I have noticed a few awesome native lizard species just drop in population, and even disappear in most areas, only to be replaced with invasives that are so common that I can find at least 3 species in my small yard(in greater #s than the natives were), at any time, and find no native species. <_<
I am aware that even with experienced hobbiests, accidents can happen, but there are plenty of irresponsible pet owners out there that release things, because they can no longer keep the commitment to their pets. I believe that sales of exotics, to just anyone in a climate like this, is what needs to be restricted.
Even if it means restrictions on what I keep, I agree that something has to be done to prevent it from getting worse.
It is definitely not a comforting thought that my kid could encounter a mamba, cobra, or large constrictor, when outside playing.
I have loved reptiles since I can remember, but it was a lot more comfortable when I "thought" that there were only 4( easily identifyable) types of venomous snakes to be found in North America. Rattlers, Cottonmouths, Copperheads, and Corals.
