Take a moment and truly envision the alternative. What if we don't explore space? Are we content remaining confined to Earth for eternity? Do we stay on earth and watch ourselves destroy the environment, watch our resources dwindle, and sit back as the sun decays into a red giant and envelopes our planet?

The choice is obvious.

In my opinion, after a certain point, will become an economic necessity; i.e. a lack of resources on earth & cheaper manufacturing costs in space will drive humanity spacebound.
