In the deep ocean, whales and fish that vomit (spew) or defecate (piss) create "marine snow"—organic matter that sinks to the abyssal plain. Bottom-feeders recycle that spew into biomass. The ocean is the largest recycling system on the planet, and it runs on vomit.
Reclaiming nutrients from human waste reduces the reliance on synthetic fertilizers, which require high-energy, fossil-fuel-intensive processes to produce (Haber-Bosch process).

Let’s start with the most obvious of the three: urine. For most of human history, urine was a nuisance, a sanitation problem, or a punchline. But to a chemist or a survivalist, urine is a remarkably complex and valuable aqueous solution.
Finally, we recycle. Not always out of virtue, but out of necessity. In a closed system like Earth, there is no "away" to throw things. The spew of yesterday becomes the soil of tomorrow, often through grueling, mechanical effort. We filter the water, we re-process the scrap, and we try to turn the bile back into bread. It is a frantic attempt to close the loop before the waste drowns the engine. Conclusion Reclaiming nutrients from human waste reduces the reliance
Astronauts on the International Space Station must recycle everything. They cannot get fresh water deliveries from Earth easily.
: When urine is disposed of outside, nature filters it through soil and evaporation. It eventually returns as rain, meaning the water molecules we drink today may have once been part of someone's urine years ago.
