Cheetahs live primarily in grasslands and benefit the ecosystem by keeping the animals it hunts at healthy populations. Cheetahs, when possible, hunt the weak and slowest of several species of animals.
Cheetahs are now endangered because they are hunted by man for their fur. Without these animals, the population of herbivores would become out of control, which in turn would lead to a loss in vegetation and degradation in soil quality.
Because cheetahs hunt the slowest and least-intelligent members of a species, they are depleting the animal kingdom of weak genes, making other species of animals stronger and smarter, states the Tree of Life. This allows future generations to be stronger and smarter than the generation before them.
