The ozone layer is important because it acts as a protective shield that absorbs the majority of the sun's harmful ultraviolet (UV) radiation, preventing it from reaching the Earth's surface. This helps to protect both human health and the environment by reducing the risk of skin cancer, cataracts, and other health issues related to UV exposure. Additionally, the ozone layer plays a key role in regulating the Earth's temperature and climate by influencing the distribution of heat in the atmosphere.
