Species go extinct when they are no longer adapted to their environment. Other than human impacts, this can happen for a number of reasons. A predator may get more efficient at hunting a species, and cause extinction. Or a species may be outcompeted by another that eats the same types of food. Nevertheless, it is a mistake to underestimate human contribution to current species extinction, as many scientists believe we are causing a mass extinction event, a rate of extinction far larger than the background rate.
