How does poaching affect the world?

Animals that are poached are most likely to become extinct or endangered. If one animal dies then many other animals will to. Ex: Ther are 27 foxes in Lauraville. A farmer kills one fox evry day for 27 days. Now the bunnies won't get eaten and they will over-populate the area. But If the bunnies died out and the foxes stayed alive then the foxes will soon die because they don't have anything to eat. Get it?
