A long and wicked life followed by five minutes of perfect grace gets you into Heaven. An equally long life of decent living and good works followed by one outburst of taking the name of the lord in vain- then have a heart attack at that moment and be damned for eternity. Is that the system?
Robert A. HeinleinBut space travel can't ease the pressure on a planet grown too crowded not even with today's ships and probably not with any future ships-because stupid people won't leave the slopes of their home volcano even when it starts to smoke and rumble. What space travel does do is drain off the best brains: those smart enough to see a catastrophe before it happens, and with the guts to pay the price-abandon home, wealth, friends, relatives, everything-and go. That's a tiny fraction of one percent. But that's enough.
