I've peed on a ton of bushes before and I'm pretty sure I scarred those bushes forever. But! If I were to use this filtration system that pumps pee from a urinal to water plants...I'd totally be helping the environment.

The system, called When Nature Calls, is in the concept stages right now but the idea is that the urine you spit out in the urinal will be filtered through charcoal, crushed limestone and greensand before it reaches the plants. I had no idea those materials did any filtering so maybe it adds nutritional value.
Though seeing my pee help something grow would sorta freak me out, I'll suck it up. I can't wait to use this at the bar. [Tuvie via Tree Hugger]
