Discuss how man affected the environment?

Ans. During his development and expansion, man totally ignored the environment. He ruthlessly carried out his activities without considering its impact on the environment. Some of the basic impacts of this expansion are:

1. Deforestation: Trees absorb carbon throughout their lives by the process of photosynthesis. As man evolved, he slowly destroyed the forests. This caused several problems: less absorption of carbon dioxide from the atmosphere and more carbon released into air than being absorbed.

Pollution: Man is responsible for three kinds of pollution: air, water and land. The burning of fossil fuels and dumping of waste in water bodies are some of the examples of pollution.
