The ozone layer plays a crucial role in protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation. This absorption prevents most of the UV-B and all of the UV-C radiation from reaching the Earth's surface. Without the ozone layer, these harmful UV rays would cause serious health issues for humans, such as skin cancer, cataracts, and weakened immune systems. Additionally, UV radiation can also harm marine life, crops, and ecosystems. Therefore, the ozone layer acts as a shield that helps sustain life on Earth by maintaining a safe environment from the harmful effects of UV radiation.
