Question

What is a recent, dangerous threat to the Everglades ecosystem?

Answer 1

Burmese pythons, Cuban tree frogs, and Nile monitor lizards.

Explanation:

These three species, which are not native to Florida, have established breeding populations in the Everglades. They are predators which hunt and out-compete native species, and they have no natural enemies. Unfortunately, they are too well-established to be eliminated, though efforts are continuing to control them.
