What is the primary focus of the Montreal Protocol?

Reducing carbon emissions
Ozone layer protection
Water pollution control
Waste management

The correct answer is: Ozone layer protection

The primary focus of the Montreal Protocol is the protection of the ozone layer. This international treaty, which was adopted in 1987, specifically aims to phase out the production and consumption of substances that deplete the ozone layer, such as chlorofluorocarbons (CFCs) and halons. The significance of this protocol lies in its role in addressing the thinning of the ozone layer, which is crucial for blocking harmful ultraviolet (UV) radiation from the sun. This protective layer plays an essential function in maintaining life on Earth by reducing the amount of UV radiation that reaches the surface, thereby helping to prevent skin cancer, cataracts, and other health issues, as well as protecting ecosystems. The other options do not align with the main objectives of the Montreal Protocol. While reducing carbon emissions, controlling water pollution, and managing waste are all critical environmental issues, they fall under different policies and treaties that address climate change and water quality rather than specifically focusing on the ozone layer. Therefore, emphasizing the protection of the ozone layer establishes the Montreal Protocol as a vital instrument in global environmental governance.
