What is the primary aim of the Montreal Protocol?

• A. Increase greenhouse gas emissions
• B. Protect the ozone layer
• C. Promote industrial growth
• D. Regulate all environmental emissions

Answer: (B)

The primary aim of the Montreal Protocol is to protect the ozone layer. This international treaty, established in 1987, was created to phase out the production and consumption of substances that deplete the ozone layer, particularly chlorofluorocarbons (CFCs) and halons. The ozone layer is crucial for life on Earth as it absorbs the majority of the Sun’s harmful ultraviolet (UV) radiation. By reducing the emissions of these ozone-depleting substances, the protocol aims to prevent further damage to the ozone layer and allow it to recover over time. The success of the Montreal Protocol has been significant, leading to a decrease in the quantities of these harmful substances in the atmosphere and contributing positively to environmental health and human safety.
