Iguanas may be growing more tolerant to the cold, and that’s bad news for Florida

That’s bad news considering iguanas are invasive, propagate profusely and wreak havoc on homes, gardens, sidewalks, pool decks, seawalls, boats and anywhere else they eat and, well, poop. They’re so destructive, the state of Florida issued a call for homeowners to kill them. (It later clarified the statement, saying it’s best to call a professional to do the deed.)
