Ozone Depletion and Its Impact on Antarctic Biota

Ozone depletion refers to the thinning of the ozone layer in Earth’s stratosphere, primarily due to chlorofluorocarbons (CFCs) and other ozone-depleting substances. A recent study has highlighted ongoing issues with the ozone hole above Antarctica, noting its unusual persistence and potential dangers to local biota, particularly during the vulnerable breeding season of many species. The Montreal Protocol has played a crucial role in mitigating this problem by phasing out the production of CFCs and aiming for a complete recovery of the ozone layer by the 2060s. The study underscores the importance of continued research and international cooperation to protect Antarctic ecosystems and manage the impact of UV exposure on its flora and fauna.
