The earth has already tried to wipe us from existence on many occasions. The earth always has a way of dealing with particular circumstances such as over population. All it takes is a simple virus or disease and that's the end of an entire species of animal. It is only because of modern medicine and technology that we have been able to survive this long. The earth was not made to hold a population of 7 billion plus people and continually rising, cutting down our forests, building cities, polluting the environment, draining the earth of its natural resources and wiping out entire species of animals for our food. Every living thing on this planet could not have done as much damage to the earth in a million years that we have done in a mere couple hundred years. Everything we do is not natural. One day the human race could be wiped out by a "super virus" without a known cure, that is if we do not die from this apparent "Apocalypse" first. lol
