I've heard that the ozone layer is being damaged by the use of CFCs in aerosol sprays. Is this true?

Yes, it’s true. The ozone layer is a thin layer in the stratosphere that absorbs ultraviolet radiation from the sun and helps protect life on Earth. It’s been getting thinner due to human activities like air pollution, which releases chlorine and bromine compounds into the atmosphere. These chemicals react with other chemicals like ozone and water vapor, forming new compounds called “ozone-depleting substances” (ODS). ODS are very harmful to the environment and humans because they can damage plants and animals, cause respiratory problems, and even increase skin cancer risk.
