in what way man cause harm to himself and nature??

Dear Student.

Such question are for enhancing creative skills and should be attempted by the student himself. But here are some pointers to help you out in framing your answer:

• Humans are dependent on nature. What they don't understand is that the natural resources are very limited in amount and will exhaust very soon if they use them at this rate.
• Deforestation has played a key role in increasing pollution. Now this harm to nature is in turn harming the humans themselves. They are now having lung diseases and other types of cancer because of poor quality of air.
• By wasting water and other resources we have created an imbalance in the ecosystem. Many species are endangered and many of the animals have gone extinct. The ozone layer is depleting, global temperature is rising and all of this is affecting our health.

We hope that these points help you. Feel free to ask us in case you feel any difficulty in framing your answer.
Regards.
