Why is the ozone layer depleting?
assistant
The ozone layer is a thin layer of gas in the stratosphere that absorbs ultraviolet radiation from the sun. It protects us from harmful UV rays, which can cause skin cancer and other health problems. However, it is slowly being depleted by man-made chemicals called chlorofluorocarbons (CFCs). These chemicals are used in air conditioners, refrigerators, and aerosol cans. When released into the atmosphere, they react with oxygen and sunlight to produce ozone-destroying chlorine radicals.
