The ozone layer plays an essential role in shielding life on Earth from harmful ultraviolet (UV) radiation emitted by the sun. Located in the Earth’s stratosphere, it absorbs the majority of the sun's UV rays, preventing them from reaching the surface where they can cause skin cancer, cataracts, and other health issues in humans, as well as negatively affecting ecosystems and wildlife. Protecting the ozone layer is thus crucial for maintaining the health of all living organisms and the stability of Earth's climate.
