"There is a lot of truth in the idea that doing something like colonizing mars could do more good for humanity than giving people enough money to eat for a day or a week." There is? Tell me, how would colonizing Mars help the average man? Frankly I can't think of any higher calling to donate to than environmental groups. Now there are good groups and bad groups (both nationally and local) - and it's up to you to do your research. Well, I guess if our environment goes to hell, building a colony on mars might be a good idea. But somehow I doubt the "average" man would be able to afford a house on Mars.
