What a funny little article. I'm tempted to write "the Moon contains enough iron to keep 100,000,000,000 people alive for 10,000,000,000,000,000 years! After all, we all need hemoglobin!

So what if the regolith has oxygen bound within it? The inference is we can all go off to live somewhere that (a) has no protective magnetic field, so everyone will die of cancer, (b) has no atmosphere so many will die from tiny meteorites smashing into them (even something as small as 1mm will kill with enough velocity behind it - the Apollo astronauts knew they were taking a big risk even on such extremely short missions), and (c) has only 17% of the Earth's gravity, leading over time to some pretty awful physiological effects.

Why not point out that Venus has plenty of nitrogen in its atmosphere, enough to grow 100,000,000,000 tons of wheat? Oh, sure, there's the problem of 700 times the atmospheric pressure of Earth, the lethal acidity, and the searing temperatures, but plants need nitrogen and so....
