> Creating novel waterproofing chemicals that don't have naturally-occurring ways to break down and then dumping them into the water supply isn't something beavers, or ants, or birds, can do.

Genes encode proteins, proteins are chemicals, so evolution creates new proteins, and organisms often dump them to environment. The difference is that other organisms produce new chemicals through genetic evolution and not memetic evolution, like humans. Some of these chemicals are initially non-breakable, for example after lignin was introduced, it took millions of years to evolve organisms able to break it.
