Suggest a few measures for controlling carbon dioxide levels in the atmosphere.

Carbon dioxide levels in the atmosphere can be controlled by using the following steps:

(a) Avoiding the use of firewood and cow dung cakes for producing fire as it results in emission of Carbon dioxide in the air. Instead LPG should be used in the house for various purposes. It will help in reducing the amount of carbon dioxide in the environment.

(b) Avoiding use of plants and trees to light up the fire. Instead they should be used for making the manure.

(c) Avoiding use of petrol and Diesel in the automobiles. Instead compressed natural gas should be used in the vehicles as it is environment friendly.

(d) Avoiding use of perfumes, Deodorants or Air conditioners as they contains chloro-fluoro-carbon i.e. CFC’s which changes the level of carbon dioxide in the environment.

(e) Avoiding use of private vehicles, instead Public transport should be used for travelling.
