We are apex predators, and our shit contains the condensed toxins from all of the lower rungs on the food chain. The other extreme would be an animal like a cow, which shits basically smellier grass.
That's basically it. A human being that's only eaten plants has much less devastating poops.
- dmurray 1y agoI don't think this last conclusion is true. It's really about harmful bacteria, not "toxins". Even vegetarians have a complex digestive system that can harbour pathogens. Perhaps their faeces are safer to use as manure than those from a meat-eating human, but much closer to that than to a cow.
- SR2Z 1y agoI have heard that it's unusually nutrient rich - maybe not toxins, but human shit definitely causes algal blooms.

- raxxorraxor 1y agoWouldn't be the first time humans tried to use human manure as fertilizer. It always ended quite shitty (for humans).
- IAmBroom 1y agoDumping ANY manure into a body of water causes algal blooms. Fecal matter concentrates nutrients. This has happened with modern megafarms, when flooding overflows their manure pits.
- FollowingTheDao 1y agoIt is far from a certain that we are apex predators since we can survive on a largely herbivore diet. https://en.wikipedia.org/wiki/Apex_predator#Human_trophic_level https://en.wikipedia.org/wiki/Apex_predator#Human_trophic_le... And "our shit contains the condensed toxins from all of the lower rungs on the food chain." lacks any credibility unless you can provide a link I have never seen.

I’m not who you’re asking, but I can only assume that they refer to the observed phenomenon of bioaccumulation, which was factor in the unexpected harms of pesticides such as DDT on bird populations. That said, I don’t know of any risks to wildlife or the environment from bioaccumulated toxins solely due to human waste. If I am reaching and wildly guessing, I suppose folks who eat a lot of fish might pass more mercury in their waste? From what I understood, most toxins like that are processed by the liver and don’t get flushed out. https://en.wikipedia.org/wiki/Bioaccumulation https://en.wikipedia.org/wiki/Bioaccumulation
