उत्तर
- In terms of animal evolution, man came last on Earth. But he advanced in every subject because of his recall, critical thinking, creativity, and intelligence.
- By virtue of these qualities, he became the supreme.
- All the natural resources on Earth were very rapidly exploited by man.
- He degraded practically all natural ecosystems under the guise of progress and technology.
- 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 for man, no other organism on Earth can change the ecosystems in such a drastic way.
Therefore, it is rightly said that human beings have an important place in the environment.
