Man came last on the earth during evolution of animals. But due to his intelligence, imagination, critical thinking and memory, he made progress in all fields.
By virtue of these qualities he became the supreme.
All the natural resources on the earth were very rapidly exploited by man.
Under the pretext of technology and. development he made degradation of almost all natural ecosystems.
He never obeys the rules of nature.
Phenomena like pollution, urbanization, industrialization and deforestation are exclusively his creations.
Hunting and poaching other animals were his contribution to the extinction of many other animals.
Except man no other organism on the earth can change the ecosystems in such a drastic way. Therefore, it is rightly said that human beings have important place in environment.
