Every mammel on the planet develops a natural balance or a certain equalibrium with the world around them but we humans do not, we move to an area and we multiply and multiply until every natural resource is consumed and the only way we can survive is to spread to another area. There is only one other organism on this planet that follows the same pattern, a virus. Human beings in the intrest of the planet are a desiese a cancer of this eath. (Kinda makes you proud dosen't it)
