Earthworm 🐌I can't stress enough how important it is to close the nutrient cycle and utilize human excrements as fertilizers. We would save so much resources and energy while decreasing the environmental impact of our horribly expensive and inefficient sewage system and fertilizer production.
Yes, there are challenges when using human excrements (mainly pathogens and pharmaceutics), but the hazards are mostly much lower than people think, and solvable.
