What is the role of the ozone layer?

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 radiation can cause skin cancer, cataracts, and other health issues in humans, as well as damage ecosystems. By absorbing and scattering UV rays, the ozone layer acts as a shield, preventing most of the Sun’s harmful radiation from reaching the Earth’s surface. Efforts to protect the ozone layer, including international agreements like the Montreal Protocol, have led to a gradual recovery of this vital layer.
