When there are too many predators, not enough resources and a great deal of competition, an animal population dies .............. . This can be just as bad. Such a population explosion happened when the brown tree snake arrived on Guam in the cargo of a military plane 50 years ago. The ecosystem was not ready for the reptilian assault, and the snake had no natural competitors or enemies there. As a result, virtually every songbird on Guam has been eaten by the snakes.
