There are various types of harmful gases in atmosphere. Such as:

1. Carbon Dioxide (CO2): It plays a crucial role in the greenhouse effect, excessive concentrations of CO2 can contribute to global warming and climate change.

2.Ozone (O3): Ozone is beneficial as it absorbs harmful ultraviolet (UV) radiation, ground-level ozone is a pollutant.High levels of ozone can lead to respiratory issues and harm vegetation.
3. CFCs (chlorofluorocarbons):CFCs are special chemicals that were used in things like aerosol sprays, refrigerators, and air conditioners. They were responsible for ozone depletion.
4.Methane (CH4): Methane is another greenhouse gas that contributes to climate change. It is released through natural processes and human activities such as agriculture, waste management, and fossil fuel extraction.
