Solution
Montreal Protocol was signed in 1987 in Montreal, Canada. The reason behind signing this protocol was to control the emission of CFCs and other ozone-depleting chemicals. These chemicals are responsible for the depletion of the ozone layer and result in the development of the ozone hole. Disruption in the ozone layer can have a deleterious effect on all living beings and the environment.
