Burmese pythons are highly invasive to Floridian ecosystems. Back in the day, a lot of idiots would purchase them as pets without realizing how big they would get. Instead of handling it responsibly, the owners would let the pythons out into the wild when they grew too big. It sucks, but taking them out is the only reasonable way to deal with such an issue. Similar situation with wild boars, except those guys are tasty.
