The significance of the ozone layer's presence in the atmosphere is to protect life on Earth from harmful ultraviolet (UV) radiation emitted by the sun. The ozone layer absorbs a substantial portion of harmful UV rays, preventing them from reaching the surface where they can cause skin cancer, cataracts, and harm to ecosystems. Its depletion due to human activities, such as the use of chlorofluorocarbons (CFCs), has raised concerns for public health and environmental sustainability. Thus, preserving the ozone layer is essential for protecting both human health and biodiversity.
