Pollution

A:

A well-known campaign against chlorofluorocarbons in aerosols in the 1970s led to continued association of the chemical with aerosol sprays. However, this issue was entirely resolved, and aerosols are no longer a threat to the ozone layer. However, they are still not beneficial to the environment as they are one of many products that contribute to global warming and smog problems.
