Can pee help feed the world?

It’s amazing that spend so much energy on producing fertilizer while we treat urine as a waste product. It’s great to replenish soil for a bunch of plants, like cannabis.

I used to water a rosemary plant with pee... it worked really well for quite a long time, but at some point it became too much (I think).

Great idea, but I'd be concerned about pharmaceuticals, especially in heavily medicated societies like the US.
