What environmental issue is primarily targeted by the Montreal Protocol?

The Montreal Protocol primarily targets the depletion of the ozone layer, which is crucial for protecting life on Earth. It was established in response to scientific evidence showing that certain man-made chemicals, particularly chlorofluorocarbons (CFCs) and halons, were causing significant damage to the ozone layer. The ozone layer plays a vital role in shielding the planet from harmful ultraviolet (UV) radiation from the sun. By limiting the production and consumption of these ozone-depleting substances, the Protocol aims to halt the degradation of the ozone layer, helping to restore its protective function over time.

While global warming, air pollution, and water contamination are important environmental issues, they are not the primary focus of the Montreal Protocol. Global warming is specifically addressed by other international agreements, such as the Kyoto Protocol and the Paris Agreement, which focus on greenhouse gas emissions. Similarly, air pollution and water contamination involve different sources and require separate regulatory approaches outside the scope of the Montreal Protocol’s intent and goals.
