The presence in our local environment of creatures like the Formosan termite, the Bahamian curly-tailed lizard, the Africanized bee and the dreaded Cuban death's head roach is understandable, and probably unavoidable in today's free-trade world.
These uninvited guests arrived by way of shipping containers from far-off lands, or in the case of the bee, by an accidental release.
The problem of the lionfish and the Burmese python, however, can be traced to irresponsible idiots who keep these predators as interesting pets until they get too big or annoying to keep in the house.
What do you do if you're a typical Floridian who's gotten all the use out of something that he wants to, and is ready to move on? Dump it and forget it. That's what that big swamp back there, and that ocean out front, are for. You don't even think twice about letting it become somebody else's problem, because this is Florida. Other people don't worry about trashing the environment, so why should you? After all, it's pretty much trashed already.
When the place becomes so polluted and overrun with exotic, predatory wildlife that human existence becomes untenable, you can always just move to another state, the same way you moved in. Run a few red lights on your way out while you're at it. Weave in and out of traffic. Toss the packaging from your fast-food lunch on the highway.
Somebody else'll clean up the mess.
