Calm Water Violently Assaulted

Sometime you just have to wonder what we humans as self-appointed landlord of the earth are thinking. We crap where we drink. We urinate into the very place where we get fish.
It is not unnatural do do so, after all that is what all animals do, but there are just so damned many of us that we overrun the world with refuse and excretion. To top things off, as if our bodies cannot produce enough, we manufacture more crap.
I realize that I am as evil as the rest of the world. I just don't know what to do about it.
