List four products produced by burning coal.Suggest four measures for controlling carbon dioxide levels in the environment
Answers
Answer:
Explanation:
The main natural carbon sinks are plants, the ocean and soil. Plants grab carbon dioxide from the atmosphere to use in photosynthesis; some of this carbon is transferred to soil as plants die and decompose. The oceans are a major carbon storage system for carbon dioxide.
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.
