This is a bigger deal than most people realise. It's not a coincidence that our wee and poo contain the exact right ingredients for growing human food... because of course they do!

And before anyone asks, it's entirely possible to take advantage of this fact at scale. There's a substantial agricultural biosolids industry starting to form in Queensland.

If we cycle the same matter through the farm/people system, and use agricultural wastes to make up shortfalls, we can drastically reduce the pressure on soils and create a self-sustaining system. The only extra requirements are solar energy, captured by plants growing on farms, and energy for machinery, which could theoretically be supplied by the sun as well.

The above is the agricultural aspect of the Circular Economy - the kind of economy that we will need in order to live in balance with the rest of the living world.
