Ozone depletion is primarily caused by the release of human-made chemicals known as ozone-depleting substances (ODS). The most significant contributors to ozone depletion are chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform. These chemicals, once released into the atmosphere, rise to the stratosphere where they interact with and break down ozone molecules. This process releases chlorine and bromine atoms, which then catalytically destroy ozone molecules. This leads to ______ ________ ______ ___ ___ _____.
