I recycle cause I'm cheap. I fill maybe one bag per month at ~$3 each....the rest gets hauled by myself to a recycling place when I go shopping for food, etc.
I use only one side of the toilet paper though...not THAT cheap.
Humans ARE essentially walking alimentary canals...in one end...then out the other. All else revolves around this basic function....people stop wars...sex...raising children to eat & drink don't they?
