Follow up -- Considering that at some point we'll reach saturation in the amount of buildings we need, and the world population will necessarily stabilize itself due to resource limits, are there other ways to take CO2 out of circulation besides concrete that don't come with the additional emissions of concrete?

For example I believe plants make sugars using CO2 and water? Can we make a ton of sugar (or other environmentally safe molecules) artificially using CO2 and bury it in the desert? (Sorry for my naivity, I'm not a chemist!)
