The Full Story
In 1985, scientists from the British Antarctic Survey published evidence of a severe seasonal depletion of stratospheric ozone over Antarctica. The finding shocked the scientific community because ozone protects life from harmful ultraviolet radiation. The discovery helped spur international action, including the 1987 Montreal Protocol, which limited ozone-depleting chemicals such as CFCs. The ozone layer has since shown signs of recovery, though healing is gradual.
