What are the factors responsible for global warming?

Greenhouse effect is a natural phenomenon which occurs with  the help of gases like CO₂. The ozone allows heat to enter inside the Earth's atmosphere so that the Earth remains warm, it acts like a blanket and prevents harmful radiations from entering the Earth. But lately, too much of pollution and overuse of CFCs has started weakening the ozone and letting harmful radiations inside. If this goes on then the Earth's temperature will rise so much that life will not be possible. This inflammation of the Greenhouse effect is called "global warming".

The main factors are some harmful gases which increases Greenhouse Effect:
1) Carbon dioxide (CO₂)
2) Methane (CH₄)
3) Water (H₂O)​​​​​​
4) Nitrous oxide (NO)
5) Ozone (O₃)
6) Chlorofluorocarbons (CFCs)
7)  Burning fossil fuels 
8) Deforestation & Tree-Clearing
9) Agriculture & Farming
