Mars has abundant CO2, Water (ice), Nitrogen, and even phosphorous. Those are the big things you need to grow food. What is this silliness of "for all intents and purposes it's a vacuum" and "plants don't grow in a vacuum"? Humans can build structures that hold pressure, we can build greenhouses on Mars. That's where we'll grow crops and feed the population of Mars. Please don't pollute the comments here if you're not even going to bother with the bare minimum of intellectual seriousness. Yes we can concentrate the atmosphere of Mars to higher pressures, this isn't even hard. Yes we can build structures to grow crops in. Yes we can keep structures insulated and heated to maintain higher temperatures than ambient outside conditions, as is done routinely across the globe every second of the day on Earth. Is that the limit of your straw-man argument here or do you have anything of substance to say?

> Please don't pollute the comments here if you're not even going to bother with the bare minimum of intellectual seriousness. Ah, yes. The new HN. Everyone else is stupid and lazy. > Yes we can keep structures insulated and heated to maintain higher temperatures than ambient outside conditions, as is done routinely across the globe every second of the day on Earth. Please show me on-Earth greenhouses which are pressurized to 14PSI over external. Constructing a greenhouse isn't hard. Constructing a pressurized greenhouse on Mars is rather a lot harder. > Is that the limit of your straw-man argument here or do you have anything of substance to say? Yes... everyone else is stupid and lazy. And has bad intentions. And isn't honest. Welcome to the new HN. You could take my words at face value. But it's easier (and more intellectually dishonest) to assume the stupidest possible interpretation, and then attack them for your own inadequacies.
