When man first appeared on earth planet, he had very little awareness
about the role of the environment around him. Because of his limited
knowledge, he lived within the provisions of earth's natural surroundings.
This in effect did not disturb the equilibrium between man and
environment of the planet earth. As millenniums moved ahead, man on
earth grew curious of his surroundings and started exploring it.
Ultimately it leads to inventions and technological advancements that
had profound impact in shaping the environment.
Human beings reside within the environment and are dependent on the
environment for their survival. We can classify environment into natural
and artificial environment. Human beings have used both their mind and
technology to make use of their natural environment and transform it into
a more intensive artificial environment. The natural environment has its
own special balance. But, the intensive activities of the society have
destroyed this balance and have caused severe environmental
problems. Apart from these activities, deforestation, extinction of
biological resources, global population explosion and the growing
demand for food have caused many environmental problems for human
beings. . The unsustainable use of resources such as water and land by
human beings have caused the following problems:
 Severe degradation of land
 Increasing poverty and starvation
 Increasing water demand
 Declining water quality
 Increasing energy demand.
In this unit, let us study in detail about the interactions involving man and
environment, impact of human growth and the development of a
sustainable environment.
