Python hunter Bob Freer says the proliferation of pythons in Florida's Everglades reflects only part of the state's problem with unwanted exotic species, The New York Times reports. Freer has also encountered cobras, black mambas, emus and ostriches in the area, as well as many more abandoned horses since the recession. Biologists say the problem is indicative of disrespect of animals and the environment. "People need to view exotic species invasions as pollution -- biopollution," said David Hallac, chief of biological resources for Everglades and Dry Tortugas National Parks.
