And 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.
The perchlorates in the Martian regolith he uses for most of the soil would kill him faster.
Fair enough, I just knew about the feces because I wanted to have some way to actually use my dog shit. It’s not really doable at home, unfortunately.
Film theory did an interesting video where they concluded it’d be okay since he’d only be intaking a little over time. (Not saying that’s true)
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.
Yeah they reference this in the book, it’s always from him when he uses the bacteria (meaning in theory it’s only his own pathogens or bacteria). He uses his crews shit that’s been dried and left in Martian temperatures so it’s sterilised.
