This weekend I came across the Animal Planet show called Killer Aliens. This is the basis of the show:
Welcome to ground zero in America for invasive species: Florida. The Sunshine State is being overrun by lethal Burmese pythons, feral hogs, Nile monitor lizards, and Gambian rats the size of cats - all non-native species that have been imported by humans. These foreign invaders are wreaking havoc on the ecosystem and natural species are being thwarted. With no natural predators, their populations continue to spread rapidly throughout the state, spreading disease, destroying vegetation and crops, preying on native species and in the worst cases harming humans. It's a race against time to fight this ecosystem nightmare. The front lines are expanding, and no one knows where they are headed next.
