I think it was in Mrs. Cancino’s class that we did the animal population charts. When two species rely on each other in a predator/prey relationship, they are constantly fluctuating in population size. When the mouse population becomes large, the hawks flourish, until the mouse population is over-killed, then the hawk’s population falls, and the mice start to grow again.

Of course, humans are unique in that we have conscious, deliberate ways of controlling our population, as well of that of animals.

Certainly, there is not an unlimited amount of fish in the sea. We’ll just have to start controlling population, like we do with cows, chicken, etc.
