Urine for a Surprise

Are you aware that you produce several pints of sterile fertiliser every day? 95% of our urine is water, 2.5% is urea, the body's waste, and 2.5% is made up of minerals, salts and enzymes that plants love. The Journal of Agricultural and Food Chemistry has run tests demonstrating that beets fertilised with human urine grew ten percent larger. Little wonder, for we were made to live in a garden.

I've also been pondering awhile now the scandal of flushing away our waste with water that's good enough to drink. With many around the world drinking dirty water, we squander our purified stuff to wash away down our sewers. 

One could therefore make both a moral and an economic argument to flush less, and fertilise our gardens more. The question is, who is brave enough to try it?
