You know that Mars atmosphere don't capture oxygen right? [1]
No way to grow food there unless you export a whole lot of greenhouses and set up an artificial biosphere, but without the conditions that we take for granted on earth.
This is already hard to do in deserts or in the Polar regions, where we have plenty of oxygen and free moisture flowing in the atmosphere.

We have already worked out how to produce metals and polymers from martian resources. > This is already hard to do in deserts or in the Polar regions, where we have plenty of oxygen and free moisture flowing in the atmosphere. Sure, there will be considerable challenges. I don't see anything that will be insurmountable.

- hazov 14y agoIt's not, but a huge pressurized dome would be pretty much expensive, I do not think a colony on Mars would be able to produce more than subsistence level for the pioneers.
- stcredzero 14y agoThere has already been consideration of producing polymers on Mars from the atmosphere. Agricultural domes would not have to be reliable as living spaces, so these could be built cheaply as inflatable structures. So mars could build its own greenhouses.
