SAGAN'S BOOK, PALE BLUE DOT

[Randall_F_Brich@RL.gov]

     Regarding the fragility of planet earth as alluded to in several 
     recent RadSafe posts, the subscribers might be interested in checking 
     out Carl Sagan's book, Pale Blue Dot. Sagan begins by dispelling old 
     myths centered on the anthropic principle and provides an amazing set 
     of photos of earth from a different perspective. One such photo shows 
     the earth and its very thin atmosphere as seen by a german astronaut 
     aboard the shuttle. The astronaut's realization that the earth's 
     protective layer is so thin ought to be a wake up call for all those 
     really concerned about the global impact of current energy policies. 
     Happy reading.
