i am going to take wild guess and say that the burmese pythons taking over the everglades and the populations there are overflated.
Even if burmese pythons are reproducing, laying eggs, and eggs are hatching, there are still major adversities of surviving life for them.
They just don't hatch out of the egg and eat all of the native wildlife...they also provide a food source to many predators that live there.
maybe it's there, but are they just going to ban the importation of burms and af. rocks?
