The ozone layer is important because it acts as a shield that protects the Earth from the harmful ultraviolet (UV) rays of the sun. It helps to prevent these UV rays from reaching the Earth's surface, which in turn reduces the risk of skin cancer, cataracts, and other health problems in humans. Additionally, the ozone layer plays a crucial role in regulating the Earth's temperature and climate by absorbing and reflecting some of the sun's heat. This helps to maintain the balance of ecosystems and supports life on our planet.
