You are saying bury it as calcium carbonate, not as a gas. Well, whatever is cheapest and most convenient. There might be market for carbon or carbon compounds on the Moon or Mars for all we know. We might send millions of tons a day up by space elevator and dispatch it around the solar system. I doubt that will happen, but you never know. I doubt the earth will export foodstuffs to Mars. That would be exporting carbon and water. It seems a lot easier to grow food locally. Fresher and tastier. - Jed
