Essay on Cause of Global Warming in 100 Words
~107 words
Global warming is caused by human activities that send harmful gases into the air. The burning of coal, petrol, and gas in factories, vehicles, and homes releases carbon dioxide. These gases are called greenhouse gases. They form a layer in the sky that traps the heat of the sun, so the temperature of the earth is rising slowly. Cutting down forests is another big cause, because trees absorb carbon dioxide. Smoke from vehicles and factories also increases these gases. If we do not control these causes, the earth will become hotter and hotter. We must stop polluting the air and plant more trees to save our planet.

Frequently Asked Questions
What is the main cause of global warming?
The main cause is greenhouse gases like carbon dioxide released by factories, vehicles, and burning of fuels.
How do greenhouse gases warm the earth?
They form a layer in the sky that traps the sun’s heat, like a greenhouse.
Why does cutting trees cause global warming?
Because trees absorb carbon dioxide, and without them more gas stays in the air.
