What are the causes of the ozone layer depletion?
assistant
The main cause of the ozone layer depletion is the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances into the atmosphere. These chemicals were used in a variety of industrial processes, including refrigeration, air conditioning, aerosol propellants, and fire suppression systems. When released into the atmosphere, these chemicals react with sunlight and form chlorine compounds that break down the ozone layer. This process has been linked to an increase in ultraviolet radiation reaching the Earth's surface, which can lead to increased rates of skin cancer, cataracts, and damage to plants and animals.
