<human>: I've heard that the ozone layer is being damaged by the use of CFCs in aerosol sprays. Is this true?
<bot>: Yes, it’s true. The ozone layer is being damaged by the use of aerosols. Aerosols are tiny particles suspended in air or water. They can be made from a variety of materials, including plastics and other synthetic materials. When these aerosols are released into the atmosphere, they can break down the ozone layer, which protects us from harmful ultraviolet radiation.
