I remember looking at a friend's chemistry textbook and it said something like there are 500,000 unregulated chemicals currently in industrial use. How we are not more screwed up metabolically is actually somewhat surprising to me. We didn't evolve to metabolize and tolerate these chemicals. So they just disrupt homeostasis of the organism and even the environment. This is the ultra smart animal version of exponential growth killing off its own species
