That just goes to show... evolve, or nature will take care of it for you.

We were able to learn and adapt rather than evolve for much of the existence of humanity. It kept us a step ahead of competition in the food chain.
Unfortunately, microbes evolve quickly. More quickly when they are allowed to replicate millions of times.
And a segment of our population has chosen to proudly discount any idea of "learning" or "education".

This seems to have allowed competition to catch up a little bit. And now our poop is red on a map in houston.
