The ozone layer is a critical component of the stratosphere, located approximately 15 to 35 kilometers above the Earth's surface, and it serves as a protective shield by absorbing the majority of the sun's harmful ultraviolet (UV) radiation, particularly UV-B and UV-C rays. The depletion of the ozone layer occurs when certain man-made chemicals, primarily chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances (ODS), release chlorine and bromine atoms in the stratosphere. These reactive halogen atoms participate in catalytic cycles that destroy ozone molecules, significantly reducing the overall concentration of ozone in the stratosphere. A single chlorine atom can destroy thousands of ozone molecules before being deactivated, which amplifies the effect of even small amounts of these chemicals. Ozone layer depletion has been observed prominently in polar regions, leading to the phenomenon known as the "ozone hole," particularly over Antarctica. The presence of polar stratospheric clouds during the cold winter months accelerates the release of active
