The importance of the ozone layer in the Earth’s atmosphere lies in its ability to absorb the majority of the sun's harmful ultraviolet (UV) radiation. Located in the stratosphere, this layer protects living organisms from UV radiation's damaging effects, which can lead to skin cancer, cataracts, and negatively impact ecosystems. The ozone layer is crucial for maintaining biological health and supports life on Earth. Threats to this layer, such as chlorofluorocarbons (CFCs), have prompted international efforts for its protection and restoration.
