What Role Does Ozone Layer Depletion Play in UVB Exposure?
The ozone layer in the Earth's stratosphere plays a critical role in filtering out harmful UVB radiation. Depletion of the ozone layer, caused by pollutants such as chlorofluorocarbons (CFCs), has led to increased UVB levels reaching the Earth's surface. This has heightened the risk of UV-related health issues and environmental damage. International efforts, like the Montreal Protocol, aim to reduce substances that deplete the ozone layer, thereby mitigating the impact of UVB exposure.
