Peak phosphorus is one of the peak i'm less worried about in my lifetime or my children's lifetime. Morocco reserves are probably underestimated, as are Algerian reserves. As long as Morocco stay stable and is help by its economic partners during hard times (France and Spain mostly), it wont' be an issue.

But you're right, hydroponics solve this issue.

Yeah, I’m not worried much about it either... it would be a benefit to reduce phosphorus mining in general due to its environmental impact, but even that can probably be addressed in other ways.

I don’t know the geography well enough to know if this is a problem, but I thought half of the area claimed by the Moroccan government wants independence and has a long-running low-energy struggle going on to achieve that end?
