CHAPTER 20 : THE ENVIRONMENT
Man in modern times, faces a great ecological crisis,
namely the pollution of his environment. This same environment had
once been uncontaminated and quite hospitable for him. We may regard
environmental pollution as the unfavorable alteration of our surroundings.
This is largely because of manís actions. It is also because of
direct or indirect effects of changes in energy patterns, radiation
levels, or an abundance of organisms. It is only in the latter half
of this Century that man realized that the planet that they were
living in was being threatened by pollution and over-exploitation
which were the results of greed and ignorance. During the 1980ís
some of the governments passed laws to protect the environment.
Some scientists however believed that, we might be already too late
in our efforts.
