Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment. But you humans do not. You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area. There is another organism on this planet that follows the same pattern. Do you know what it is?
A virus.
He wasn’t entirely wrong. Why do we do this? Humans are renowned for our reasoning skills, but here they fail us. Otherwise we’d grasp the dangers of overpopulation and environmental depletion. Carrying on as we do wouldn’t seem to be in our collective best interest, and yet we do as we do. This leads to us murdering one another over territory and resources. If it isn’t in our best interest, than whose? Is our detrimental behavior for the benefit of some unseen mover? Perhaps some distant deity is growing souls to harvest into his celestial host. Or maybe we’re merely kine for some sinister alien race. The truth is likely far more dull than either of these options, but I’m curious to know nonetheless.
