Why an exponential population growth rate is unsustainable. Why, over the last twenty years, Georgia has steadily raised the limit on deer that hunters can kill. What is likely to happen to an herbivore population if predators that eat them suddenly decline or increase. Why animals that eat the same food, or need the same resources, are competitors.
