If animals are not kept under control, then they will become overpopulated, however, if over hunted, a species of animal could become in danger of extinction. Also, just like an overpopulated species, an under population of animals can affect the ecosystem it lives in. According to an article titled “Causes, Effects,” the website states: With reference to how over hunting affects the interconnectedness of the ecosystem, it means other animals, trees, and plants are equally affected. As previously discussed, it causes either an increase or decline of a specific population within a habitat. When this happens, it directly impacts the natural habitat in that it gets rid of natural predation and population growth which in turn disrupts the food chain.
