I agree with several comments that to ensure survival of the species we need to colonize the Moon and Mars as soon as possible. This will require that we improve our launch efficieny (space elevator or EM rail launcher) and put people in harms way to push the science forward in self-sustaining eco systems.
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
