I can't condone any "round up" or mass killing of native species...I understand the python hunts in the everglades and agree that those species need removed, but not our native snakes. Or alligators...
Unless you are hunting something for food or it is an invasive species risking the natural balance of an area then there is never a good enough reason to kill it. Humans need to learn that we share the world with potentially "dangerous" animals and we should not kill them because *our* population is encroaching on their lands.
