     4 Text 3 Man's Use of the Environment

      Man is an animal, and is a part of the so - called "web of life". There is,
however, an important difference between man and all other organisms. To an
unprecedented degree, man has been able to manipulate other species and the
environment itself. In the process his numbers and needs have increased dramatically,
and are still increasing. Yet, the capacity of the environment to supply these needs is
limited, and man's exploitation of the environment tends to reduce that capacity
clearly, this constitutes a collision course, vividly reflected in the axiom that man's
future existence on earth is not threatened by any species other than, himself.
      The thesis I wish to expound is that failure to observe some ecological found
rules has put man into this position. Ecology is the study of organisms in relation to
their environment; it deals with the environmental requirements of single species and
with whole populations or communities, with the way in which organisms influence,
and are influenced by their environment; and with the way in which organisms
interact with one another.
      If man is persist on this planet indefinitely, I believe he must adopt a new ethic,
based on ecological premises, to guide his future activity. I would like to consider
first aspects of the evolution of the global environment itself, and of the way in which
organisms live together, finally looking at the effect of man's past activities, and
pointers to the future.
