Thanks for the link to one of my favorite websites, http://space.com, the sister website to http://livescience.com. After reading the article on vulcanism on mars, though, I have to say I wouldn't worry too much about volcanic activity raining on your eutopian parade -- seems the youngest activity is at least a million years ago, and more likely 3 to 10 million, and if it is active it would be "one every 10,000 years or so". Given that people still build houses around
Have you seen Dante's Peak, with Pierce Brosnan?

Speaking of carbon dioxide, did you know that navy divers use "oxygen rebreathers" or CO2 scrubbers that chemically bind with and remove CO2 from the air we breathe? They will be no doubt necessary on Mars. Usually what happens is that we pass out from a surfeit (too much) CO2 before we run out of oxygen. A Co2 scrubber removes the CO2 we breathe out so we can go on breathing the air until all the oxygen is gone. Here is a website that you might get some good facts from your Mars colony from:
As ever, I enjoyed your post!
