Mars sounds pretty cool to me, so I voted for it!
On a recent documentary on discovery channel they said that the worlds reserves are almost used up. They said Minerals will be gobbled up world-wide soon and no alternatives are being researched.
Chromium is almost gone already. Africa is the worlds largest supplier of chromium and they have dug almost all of it out of the ground.
Once we have used up all the minerals, we can't go to another planet and buy some more. We only have what is here.
Bit of a doom and gloom thread but it is good to jog people out of complacency sometimes and make everyone aware that we are using up our Earth too fast. Well done Phil.
