HowManyAnd because of “The Martian”, people think going to and living on Mars would be a snap.
We can’t even rescue people from orbit.
I read the book, it’s hardly a snap. They guy eats potatoes fertilized by his own shit for like two years.
That would potentially poison him. Human, dog, cat, and generally any carnivore/ omnivore shit is considered “hot,” and must be treated before use as manure.
Treated how?
Mix it into compost so that the ratio is 30% droppings or less. This can be used as landscaping fertilizer, but even then it’s not recommended to use for food production.
And you’re saying it would be fine to use if we didn’t consume meat?
I’m unsure. I know there happens to be a correlation between the species that are (mostly) herbivorous, and their dung being able to be used with food production. I don’t know if our gut biome would prevent the use of purely vegan poo. I prefer the sewer as a solution, or a latrine.
