How are CFC harmful in the environment for living beings?

Chlorofluorocarbons (CFCs) are harmful to the environment primarily because they deplete the ozone layer, which protects living beings from harmful ultraviolet (UV) radiation. When CFCs are released into the atmosphere, they eventually break down and release chlorine atoms, which catalyze the destruction of ozone molecules. Increased UV radiation due to ozone depletion can lead to higher rates of skin cancer, cataracts, and weakened immune systems in humans, as well as detrimental effects on wildlife and ecosystems. Additionally, CFCs are potent greenhouse gases, contributing to climate change.
