I agree that humans are the biggest keystone species because if we were wiped off the earth, our loss would be damaging to the ecosystem as a whole. I believe this because we are the biggest consumers and modify our environment so much. We as humans are the primary keystone species because just like the starfish that were removed in the experiment, their removal resulted in a critical effect on the ecosystem and effected everything from the otters to the mussels. Humans are considered a keystone species because we are a major source in controlling and altering the ecosystem. In an article I read, a keystone species is usually the top of the predator food chain, so this would definitely qualify humans are a keystone species. All in all, I strongly believe that humans are the biggest keystone species out there.
