Question

“Industrial activities cause air pollution and land pollution.” Justify the statement with three arguments.
Discuss any two steps required to be taken to minimize environmental degradation to prevent water
pollution.​

Answer 1

Industrial activities :

Air Pollution ;

Release harmful gases into the atmosphere

Cause global warming due to CFC gases .

Harmful for residents if any gas leakages .

If located near residential areas the air which we breathe becomes polluted and may even cause death .

If held up into the atmosphere ozone layer gets depleted .

2. Land pollution ;

Much land used for industrial development which may again be given to residents for residential use but the land is already polluted so of no use .

Chemicals seeped in land

Leaching leads to problem in agriculture

Loss of nutrients

Prone to erosion and degradation

Prevent Water Pollution :

Ensure wastewater treatment

Don't allow any industries to release hot or dirty water in water bodies .

Strict rules to be maintained and if any industry violates ; they must be seized .

No wastage of water.

Reduce excess fertilizers reducing risk of flowing into rivers .

Practice rain water harvesting

Desalination must be a choice.

This way we can save water and ourselves.

Answer 2

Answer:

Soil Pollution has gradually become a major challenge that we need to overcome for establishing a healthy environment. Weathering of the earth’s crusts by different processes leads to the formation of soil that accumulates over the centuries. The soil is the home for a large part of bacterial biodiversity and other microscopic and macroscopic living organisms.

Explanation:

However, let us consider our very own country India. Indian economy is largely dependent on agriculture. Thus, we Indians give very high priority to the development of agriculture, fisheries, and livestock. Therefore, for surplus production, it is very important to protect crops from any type of damage that occurs due to insects, weeds, rodents and other crop diseases.

So, how do we protect crops? The very obvious answer is pesticides and herbicides. However, do you know these pesticides and herbicides is a leading cause of soil pollution? Therefore, it is very important to judiciously use pesticides because it contains lots of different harmful chemicals. Therefore, to improve soil and prevent soil pollution it is important to limit the use of pesticides and herbicides.
