MAINTAINING THE MATERIAL BALANCE OF THE EARTH.

MAINTAINING THE MATERIAL BALANCE OF THE EARTH. Mary Jane remembers hearing a conversation some years ago between two college students in a ladies room at Queens college. The first student said that she was worried that with all the launchings of space ships, there would be less matter on earth, with dire consequences. The second student acknowledged the problem, but then had the thought that there was a population explosion and that would take care of the problem. They smiled in relief.
