What would happen if some of the world’s countries broke the Montreal Protocol and industry began manufacturing and using chlorofluorocarbons again? In 3–5 sentences, describe the effect of this action on Earth’s atmosphere and surface.

Answer 1

If countries were to break the Montreal Protocol and resume the manufacturing and use of chlorofluorocarbons (CFCs), it would lead to a significant increase in ozone-depleting substances in the atmosphere. This would exacerbate the thinning of the ozone layer, allowing more harmful ultraviolet (UV) radiation to penetrate the Earth's surface. Increased UV exposure could result in higher rates of skin cancer, cataracts, and other health issues, as well as detrimental effects on ecosystems, including reduced agricultural yields and harm to marine life. Additionally, the enhanced greenhouse effect from CFCs could contribute to global warming, further destabilizing the climate.
