We live on earth in different types of surroundings. This surrounding is
our environment. We eat, breathe, clothe ourselves, reproduce and then
die. The next generation comes and the cycle goes on; and the human race
flourishes on earth.
The physical environment on the earth provides favorable conditions for
the existence and growth of different life forms, including man. These
living beings constitute the biological environment. Bothe the physical
and biological environments are in a close interaction with each other
and form a stable self perpetuating system.
In prehistoric days man lived in harmony with nature but in the course
of his evolution man has developed a new type of environment, the
man-made environment. Man is a social animal; the socio-cultural
environment also plays an important role in his life.There are three
types of environments i.e. natural, man-made and social environment.
The environment is constantly changing and this affects life on earth;
some these effects can be lasting and irreversible. So we must realize
that we should be concerned about environment
