What steps can humans take to control greenhouse gas emissions?

The two major activities responsible for releasing carbon dioxide into the atmosphere are burning fossil fuels and indiscriminate cutting down and burning of trees.

Trees absorb carbon dioxide from the air and give out oxygen. Besides, when trees are burned up, they release carbon dioxide gas into the air.

Burning fossil fuels releases a large amount of carbon dioxide into the air. This increases greenhouse gases which makes the earth's atmosphere warmer and strengthens the greenhouse effect.

Industries rely on coal and crude oil because they are easy sources of energy. They have been used for a long time to run machines, produce electricity, heat buildings, and run vehicles.
