The primary purpose of the ozone layer is to protect life on Earth by absorbing the majority of the Sun's harmful ultraviolet (UV) radiation. This region of the stratosphere, located about 10 to 30 miles above the Earth’s surface, contains a high concentration of ozone (O3) molecules. Without this protective layer, increased UV radiation can lead to an array of health issues, including skin cancer, cataracts, and weakened immune systems, as well as detrimental effects on ecosystems and wildlife. Protecting the ozone layer has been crucial for environmental management and public health.
