Like evasive chimpanzee said we need to poop INDIRECTLY in crops. Hot aerobic composting for example has excellent nutrient retention rates and eliminates nearly all human borne diseases. The main problem would be medication since some types tend to survive.
Also urine contains almost all of the water soluble nutrients that we expel and is sanitised with 6-12 months of anaerobic storage. So that’s potentially an easier solution if we can seclude the waste stream. Again the main issue would be medications.
I don’t have the answer, if it was easy we would have done it already. The main issue is we don’t have a lot of people working on the answer because we’re still in the stage of getting everyone in the world access to sanitation. Certainly the way we’re doing it is very energy and resources intensive, unsustainable in the living term, and incredibly damaging to the environment. We’ve broken a fundamental aspect of the nutrient cycle and we’re paying dearly for it.
The other problem is, like recycling, there isn’t a lot of money in the solution, so it’s hard to move forward in a capitalist system until shit really hits the fan.
I work in aerospace regulation and the latest media coverage has been quite upsetting for me. There is a huge difference between delegation (how the aerospace regulator gives approval power to people in companies) and self-regulation, but I’m not clever enough to summarise them in this format. So instead I’d like to share two facts that can summarize the outcome instead.
An airliner is a chunk of metal full of people 30,000 ft in sky propelled to near the speed of sound by burning kerosene in a tube. With all of that is safer than driving in your car or going for a swim. That’s aerospace regulation at work, and it has always included delegation. It’s almost the safest industry there is even when you include Boeing’s criminal fraud and attempts to abuse the system.
Boeing had to ground their fleet for years and now is being charged with criminal fraud for deceiving the FAA (the aerospace regulatory body in the USA). Self regulated industries rarely face consequences.
I’m not saying it’s perfect, and I wish I could explain the process better but I think it’s very effective and has a proven track record across the world. Almost all modern countries use the same regulatory framework because it delivers incredible safety at a reasonable (by aerospace standards) cost to the government.
I hope more industries transition to a similar framework. If we had an FAA for finance and environmental protection, I think we could end scam shell companies and illegal pollution in a decade. But it would probably be “big government socialism” so there isn’t much hope.
