Bradley M-Keystone species

According to wikipedia A keystone species is a species that has a disproportionate effect on its environment relative to its biomass. Such species affect many other organisms in an ecosystem and help to determine the types and numbers of various others species in a community. With that being said I do not believe that humans are a Keystone species. If humans were wiped off the earth I believe that plants and animals would keep the environment at equilibrium. Animals and plants have evolved throughout the years to become accustomed to the changing environment and I beleive if humans were not here they would continue to evolve to living without us. I do agree that humans do have an effect on the environment we have also had a negative effect on the environment and we would actually be doing the environment a favor if we were no there. The ecosystem would go back to functioning like it did thousands of years ago without our existence.
