Man and His Environment
Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth.

Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise,man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings.
