Which statement about the Montreal Protocol is true?

The Montreal Protocol is recognized as a successful international treaty aimed at phasing out the production and consumption of substances that deplete the ozone layer, particularly chlorofluorocarbons (CFCs) and halons. One of the most significant outcomes of the Protocol has been the reduction of these harmful substances in the atmosphere. As a result, scientific assessments indicate that the ozone layer is showing signs of recovery, demonstrating the effectiveness of the agreement in achieving its environmental goals. The recovery of the ozone layer, which is crucial for protecting life on Earth from harmful ultraviolet (UV) radiation, is a testament to the commitment and cooperation of participating countries in reducing ozone-depleting substances.

This success highlights not only the efficacy of international environmental agreements but also the potential for global coordination to solve pressing environmental issues. The scientific community continues to monitor the progress, and the positive trend in ozone restoration is a clear indicator of the Protocol’s impact.
