The ozone layer plays a crucial role in protecting life on Earth by absorbing 97% to 99% of the Sun's harmful ultraviolet (UV) radiation, particularly UV-B rays, which can cause skin cancer and other harmful effects [1][2][12]. It is found in the stratosphere, typically between 15 and 35 kilometers above the Earth's surface, and functions as a protective shield for organisms, preventing DNA damage and promoting a habitable environment [4][9].
