What manmade substances breakdown ozone?
Chlorofluorocarbons (CFCs), halons, and some types of hydrochlorofluorocarbons (HCFCs) are manmade substances that can break down ozone in the Earth's stratosphere. These chemicals release chlorine and bromine atoms when they reach the stratosphere, which then catalyze the breakdown of ozone molecules.
