I made a PERSONAL decision during my twenty's that I was not going to partake in the further pollution of our tiny planet by adding even one more hungry mouth for it to feed. As I was growing up I was exposed to the same information as all of my peers were, concerning how we are destroying our planet with over population, versus what the ecological balance should be. The difference between them and me is that I chose to be responsible for my every act on this planet, while they instead clung to their irresponsible and self important beliefs that this tiny place somehow needs to be further polluted by a living part of themselves.
There is nothing bloody "sacred" about the existence of our species on this planet. It is egotistical for anyone to have the audacity to think so. We share this planet with all of the other creatures who live here. And they have just as much right to live here as we do, regardless of our ability to annihilate them. Every hour, 3 more species who we share this planet with become extinct due to our over population (competition for space) and our greed.

I hate to go Mr. Wizard on you, but the continuation of our species here on this planet depends upon the continuation of every other species who we share this planet with. We are all part of an ecological chain, whether we like it or not.
