Yeast Makes Bread Rise, Therefore the World Will Explode

I believe the world is a big biological trick, humans are set up to perpetuate the species. Why do we want to move forward, why does technology move forward? What the world's thirst for innovation all about? Why is the world getting bigger, why do people keep repopulating the world? If the world were a living organism, than the highly populated areas would be infected growths. reproduction is our species purpose, much like how yeast makes bread rise. But, through my research finding old classmates from high school, I've concluded that only the ignorant breed (meaning ALL of them have bred). IS this suppose to be mean the world is going down the shitter!??
