We all live on this  GREAT SPACE SHIP  -   MOTHER EARTH.
It's ABOUT4.5 billion years old,  and has  ABOUT  4.5 billion more
years to   GO  before it IMPLODES into a  BLACK HOLE  in space.
Many of us on this space ship strive for
more space and possessions than our neighbors.
AND THIS CAUSES MOST OF OUR PROBLEMS !
