Reply to comment by genericrich in Would an arcology be conceivably possible? by peregrinkm

Didn't biosphere 2 fail due to CO2 off-gassing from the concrete they used to make it? And that was in the 90s. That both seems like an avoidable problem and in general it seems like we ought to be able to do somewhat better anyway a 1/4 century on.

Of course it would be vastly more expensive in space regardless.

Sure. But the time to do it is now and the place to do it is on Earth, before we send some poor slobs on a one way trip to a Martian grave.

I'm fine with doing it either way. If people want to volunteeer for a Mars trip, knowing the severe risks, good for them. People with explorer spirits have been doing that since time immemorial. In general it makes much more sense to risk the lives of a few volunteers than it does to spend extra 10s or 100s of millions on safety procedures for a few folks, when the same money could easily be spent on healthcare services for the poor that would save many more lives.

Hell, I'd probably do it myself. What's the value of a life here on Earth? You live, you die, it was all pointless and your only legacy is the resources you used and the environment you wrecked along the way. Whereas if you die on Mars...well at least you got to see Mars!
