The ozone layer protects the Earth by absorbing harmful ultraviolet radiation from the Sun. CFCs and other substances are destroying the ozone layer globally, especially in high-latitude areas where a large ozone hole has been observed over Antarctica for many years. Destruction of the ozone layer increases ultraviolet radiation reaching the Earth, which can cause increased skin cancer and eye problems in humans. CFCs were widely used but are potent destroyers of the ozone layer, so their production was banned in 1995, though their effects will persist for decades. International agreements have aimed to reduce CFC use but more reductions may be needed to restore the ozone layer. Individual actions like choosing CFC-free products can help
