I think what many don't know is that I live on an island. We are separated from the mainland by a large intercoastal waterway. The island is probably 80 mi long, maybe more. The waterway is 200 ft across at places and it is deep. About .5 mile south of us the island ends in an inlet that is .8 miles across. Vicious waves and strong currents are even a hazard for boats. We have high arched bridges to the mainland so critters have no way to leave. The river is a natural habitat for racoon, alligators, possom, and spawning fish. There is a lot for critters to eat and no natural enemies. The city no longer traps--they spent too much money on it so they quit. So homeowners have to pay unless, like us, they have a friend with traps. Its not a matter of human moving into animal habitat, its a forced habitat that probably started decades ago when some idiot brought over one of those cute little racoons and let it loose. I don't know.
