Seems a little speculative but pretty interesting thoughts. In regards to terraforming Mars this might be of interest: "During the daytime, plant-like microorganisms on a Martian-like surface could photosynthesize hydrogen peroxide. At night, when the atmosphere is relatively humid, they could use their stored hydrogen peroxide to scavenge water from the atmosphere, similar to how microbial communities in the Atacama use the moisture that salt brine extracts from the air to stay alive."

too late, the world will in end in 2012 ......... I fail to see in which scenario this would be better than a couple of vaults on Earth (since there would be no humans on the moon). But if tulips on the moon can convince politicians, I'm all for it.

"The first flowers - tulips or arabidopsis, a plant widely used in research - could be grown in 2012 or 2015 according to Bernard Foing, chief scientist at the agency's research department." - Bernhard strikes again :-)
