  29. Do "Happy go luckiers" think that the trend to the world population can
  30. continue without bound?  At the current rate, in less than 2000 years
  31. the volume of humanity will exceed the volume of a sphere whose radius 
  32. grows at the speed of light.

  34. All population projections I have seen show the population growth stopping
  35. in the next century.  The difference in the projections is when and where
  36. the population quits growing.  ( and probable assumptions about why is
  37. quits growing)
