It's happening before our eyes as the average size and shape of humans changes from generation to generation. And here's the good news; we are at the top of the food chain, which means - next stop extinction. We will evolve right out of existence. When I was born there were three billion humans. Today we are more than six billion of us and we are hungry and wasteful. We will get bigger and hungrier and eat ourselves into oblivion, just like old T-Rex. We'll be buried under a thick layer of our own garbage. My theory is that Racoons will inherit the earth. They are so darn smart and they love our garbage.
