Rickey Dowdy- Keystone Species

Keystone Species are species whose extinction would affect the ecological community in a negative way. Humans are not keystone species because if all humans die we will not really affect the world as much as we will be affected if certain other species die. We depend on other species more than they depend on us. Instead of species being extinct and not being able to survive, their populations would get bigger because of them not being hunted and their habitats not being destroyed. In our society today humans' existence harms species because of our lack of caring. By this i mean us humans being careless about where we throw our trash or how we neglect to take care of our environment. For example, when we cut down woods to build new shopping centers and housing developments we're sending these species off to live in places that their not accustomed to. Also we drive these big heavy machinery trucks with these huge mufflers that pollute deadly toxins. Therefore humans' absence would have a positive effect on species because their lives would be better and more productive.
