Quizplus · Accepted Answer

Chlorofluorocarbons and halons, commonly used in refrigeration systems and as fire extinguishers, were found to be major contributors to the destruction of ozone molecules in the Earth's stratosphere. This led to the formation of the ozone hole over Antarctica in the 1980s. The Montreal Protocol, signed in 1987, aimed to phase out the production and use of these substances in order to protect the ozone layer.
