Why do industrial activities rely heavily on coal and crude oil?

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.

To control greenhouse gas emissions, humans can reduce the use of fossil fuels, use clean energy like solar or wind power, plant more trees, and stop cutting down forests.
