The main reason of ozone layer depletion is due to the release of

Key Points

• Chloro Fluoro Carbon (CFC) compounds are synthetic chemicals containing chlorine, fluorine, and carbon.
• When released into the atmosphere, CFCs break down in the stratosphere, releasing chlorine atoms.
• These chlorine atoms react with ozone molecules, depleting the ozone layer and forming oxygen molecules.
• Ozone depletion increases harmful ultraviolet (UV) radiation reaching the Earth's surface, causing skin cancer, cataracts, and damage to ecosystems.

Additional Information

• CO from vehicles: Carbon monoxide (CO) is a harmful pollutant emitted by vehicles due to incomplete combustion of fuel. It is toxic to humans.
• SO₂ from fuels: Sulfur dioxide (SO₂) is produced from burning fossil fuels and contributes to acid rain formation.
• Methane gas in the atmosphere: Methane is a potent greenhouse gas contributing to global warming.
