Heretic!astro said:Surely, at this point in human history, there are more deserving projects to attend to.
We live in a disposable society. We have trashed our world almost beyond repair, at least for human habitation. What more noble endeavor is there than to explore outer space and find another planet where we can start over and have a few thousand years before we trash the new planet? The useless, ravaged earth can then be used as a galactic landfill so the new human paradise won't be full of plastic, fiberglass, and toxic waste. Win win!
