Yes but not all in the same place, so the ore would presumably be less concentrated?

Hmm, interesting. I was thinking that we could mine fresh debris from the asteroids themselves, in concentrated form. Plus saving the earth, of course.

Plan B. Crash dozens of asteroids onto the moon at a few designated locations. (Use rocks that might hit the earth or pass fairly close). Offer free mining rights to companies on a first-there-first-served basis.

>how could we have possibly made it as long as we have as a species if we are only now realizing that we can't eat enough good foods to be healthy?
Partly due to agricultural soil depletion of certain elements like magnesium, zinc, iodine.
Btw our prehistoric ancestors weren't especially healthy either:

I do eat quite a lot of broccoli but I still don't fancy eating 7 heads every day -- enough to cover two dinner plates.
So I take a magnesium tablet before bed. Less work to prepare and to digest.
The present moral aversion to supplements seems faddish to me. We've gone from one extreme in the 1960s where everyone looked forward to taking all food in pill form, like fictional astronauts, to another extreme where supplements of any kind are frowned upon by many including in the medical establishment. Some supplements don't absorb very well, it's true, and some consumers are irresponsible -- yet atoms are atoms and molecules are molecules regardless of the source.

>With normal healthy food you should get more than enough.
No, I looked into it some years ago and it seems unfeasible. For instance you'd have to eat about 15 stalks/heads of broccoli daily to get the RDA of magnesium, and that amount is likely suboptimal.

Say we were to crash potentially earth-destroying asteroids into the moon and then offer free mining rights to companies on a first-to-get-there basis.
I think we would still hear a a cacophony of moral objections. A spirit of pessimism seems to be hanging over us these days:

Not really -- for instance, at HN we pay more attention to comments that explain stuff well, refer to sources, and so on.
The bots might be a blessing, in some ways, if they result in more people looking for good explanations rather than for assertions or herd direction; assessing ideas rather than their sources.

Fasting is very relevant here because it puts the body deeper into repair and maintenance mode. My guess is is periodic fasting plus a modest regimen of longterm repair supplements would be the optimum strategy.

I read Dawkins before Darwin, which made sense. Just as, if I wanted to learn relativity, I wouldn't go to Einstein's papers first.
These might be transported back to earth. Plus there's iron, cobalt, manganese, molybdenum, nickel, aluminium, and titanium for construction of moon settlements and factories.
