Well the solution's easy innit...
Just set up huge bonfires, strategically placed around the moon's surface. Add a few oxygen bottle for y'know, combustion, set them going... let the CO2 gather in the atmosphere.. plant a load of space-trees, and other various hardy plants.. they eat the CO2, produce oxygen... and that's the moon terraformed ready for the populace to move to.
Foolproof plan. I should be King of Earth.
