of people will starve to death in spite of
any crash programs embarked upon
now. At this late date nothing can

1981: The Ultimate Resource
Increasing wealth and technology
make more resources available;
although supplies may be limited
physically they may be viewed as
economically indefinite as old
resources are recycled and new
alternatives are developed by the
market

50. Talk about:
Population growth outstripping
resource availability and thus
limiting economic development
