I had a thought once as a child that to colonize space we don't need other planets around distant stars we just need to learn to survive in space. Lots of resources in space to harvest if we can figure out the radiation, closed systems and weightlessness problems. Some problems take time to solve.

Merry Christmas - you are right that we shouldn’t think of Earth as our “closed system”. The universe is vast and the Earth isn’t a closed system as it has external forces, such as the sun, acting on it.

If it were up to me I would kick anybody off of Freerepublic who believed in overpopulation. But maybe Jim likes to leave their lunacy on display for us to mock.
