Here's a breakdown:
* Ozone Layer: This is a protective layer in Earth's stratosphere that absorbs most of the Sun's harmful ultraviolet (UV) radiation.
* Ozone-Depleting Substances (ODS): These are chemicals that contribute to the depletion of the ozone layer.
* Examples: Chlorofluorocarbons (CFCs), halons, methyl bromide, hydrochlorofluorocarbons (HCFCs)
It's important to note that while aerosols and manufacturing have been major contributors to ODS emissions in the past, these industries have largely transitioned away from using ozone-depleting chemicals due to international agreements like the Montreal Protocol. However, some ODS remain in the atmosphere and continue to deplete the ozone layer.
