Why does it bother you so much to know that in all the vastness of space one form of intelligent species on the fast track to essentially microwaving themselves in the next few generations (or less)?

Like !Luck said, we're just a speck on the ass of the universe in the grand scheme of things. Live it up, don't let shit you can't do anything about get you down, unless of course you feel you can make a difference. In which case, by all means do it up brotha mang. If that's what makes you happy.
