very optimistic, now can we all calculate the death toll after ww3 and the amount of FADING rescources it will take to get to mars, let alone the interplanetary wars that are bound to pop up. Look at how well imperialism has faired so far how do you think it will go in amplified conditions compared to that of earth?! That and the earth is being raveged by man to the point of complete destruction within this century. The first step is the space station then the moon, then minning/collony ventures to the astroid belt and then finally a mars farming colony, which is possibly the worst political mistake any one will ever make. Mars will rise up eventually it's only a matter of time. There is a simple solution to starvation, war! overpopullation, not on my watch! Man will not reach 10 bill. Oh and I hereby declare my intent to make earth a nature preserve (what little of her is left that is) closed to human inhabbitance! So Get off My Planet!
