SPACESHIP EARTH
Never was in perspective to me or the family till we went to a star party one nite about 4 yrs ago, Prof there showed us the moon and other planets and when he went to other stars and nebula he said those objects light left their origin years ago , I brought up where would we be in a few million years and he said MAYBE EXTINCT!!! Solar flares, rouge comets, collisions with asteriods, the EARTH has fared well in the last 10,ooo yrs or so for a societies to develop. Now we gotta co-operate and maintain it. That's the HARD PART.
