why do we need to save wildlife?

We need to save wild life because all animals and plants rely on one another for their survival. For example certain flowering plants rely on hummingbirds to pollinate them or else the plant dies and/or can't reproduce. If they we do not saved them, then they would be extinct. When one thing becomes extinct, it impacts something else and that goes extinct or becomes overpopulated and the pattern continues like that all the way up the food chain - which even impacts us sooner or later.
