A) Impact of industries on atmosphere :
1. Modern industries by burning of fossil fuels release large qualities of carbon dioxide and other chemicals into the atmosphere.
2. These chemicals pollute the atmosphere and lead to global warming and acid rains.
3. Burning of fossil fuels and release of enormous amounts of waste materials by industries contaminate air, water and soil.
4. Industrial emissions of greenhouse gases cause an increase in the atmospheric temperature and thus it leads to greenhouse effect.
B) Impact of industries on water:
1. Many industries use chemicals and metals which they release into the streams and rivers.
2. These metals like mercury are consumed by the micro organism and in turn become the food of fishes. When human beings eat these fishes, it causes ill health for them also.
3. Many toxic synthetic chemicals that cannot be broken down at all by natural processes can cause serious harm to people, plants and animals.
C) Impact of industries on soil:
- Soil contaminated by heavy metals may pose a great threat to human health if the heavy metals enter the food chain.
- Soil contaminated by industrial chemicals can have negative effects on seed germination and dry matter production.
Thus intense human industrial activity has had profound impact on the air, water and the land around us.
