Kway, you are not wrong, and yes, we do need to do everything in our power to turn our efforts into reducing the amount of destruction. But, my point is, everytime this subject is talked about, it is as if it is due to human involvement which is not entirely correct. The cyclical changes are natural and we as humans are only speeding up the process. But, to say it is caused by humans is incorrect. Human interaction is "part" of the reason.
