The Human Population is a mess!!!!

Humans believe since their the smartest species on the planet they can destroy it. This sort of thinking is the one that got us to this disaster. We have finally noticed that we are reproducing to quickly, but still we make no effort in helping prevent it. I believe that their should be rules like in china where we can only have one child. We should all take that pledge like Dr. sighn has and make an effort and try to stop reproducing so much. The animals that we use to see in the zoo, like for example the gorillas, are no longer their because they are becoming extinct. Due to all the damages we have done as humans the species now have to pay. If we are the smartest then why don't we have the capability to stop harming the environment.
