Question

Quizplus · Accepted Answer

The Montreal Protocol, an international treaty signed in 1987, was designed to protect the ozone layer by phasing out the production of numerous substances responsible for ozone depletion. It has been successful in reducing the emissions of ozone-depleting chemicals, and scientific assessments predict that the ozone layer will gradually recover, with significant recovery expected after 2050. This success is attributed to the wide adoption and implementation of the protocol by countries around the world, contrary to the implications of choices A, B, and C.
