The Fuzz saw this on NPR.
Thought it was worth passing on.
Should We Return The Nutrients In Our Pee Back To The Farm?
"Then they're pooling the urine... and eventually giving it to a farmer, who's putting it on her hay fields in place of synthetic fertilizer."
"...it's foolish and wasteful to part with the precious nitrogen and phosphorus that moves from the food we eat right through us — especially when farmers have to buy fertilizer at great expense to put those very same nutrients back into the soil."
Makes sense to The Fuzz.
