Quizplus · Accepted Answer

The decrease in atmospheric ozone over the Antarctic, known as the ozone hole, was caused by the release of CFCs into the atmosphere. This led to the Montreal Protocol, an international agreement to phase out the production and use of CFCs and other ozone-depleting substances. Most industrial nations have since decreased their production and use of these substances in order to protect the ozone layer.
