Nearly 40 years ago, scientists sounded the alarm that emissions of industrial chemicals called chlorofluorocarbons (CFCs) were eating a hole in the earth’s ozone layer, exposing the planet to harmful levels of radiation from space. The international community responded quickly to enact a ban on CFCs called the Montreal Protocol. It went into effect in 1989 and was universally ratified by 197 countries, including every member of the United Nations, as well as the European Union. It curbed emissions and was declared a major success.
