In the 1980s, scientists discovered a massive hole in the ozone layer — Earth’s invisible shield against deadly UV rays. What caused it? A man-made chemical hiding in our fridges, sprays, and foam — CFCs. As sunlight broke them apart, they released chlorine that destroyed ozone molecules by the millions. This video explains how the world came together under the Montreal Protocol, how we stopped the damage, and how the ozone layer is finally healing — expected to fully recover by 2066. But there’s a catch: the chemicals we used to replace CFCs now contribute to global warming. So, what really happened to the ozone layer — and what did we learn from it? 🌍 #OzoneLayer #ClimateChange #MontrealProtocol #EnvironmentalFacts #ScienceExplained #earthscience ----- Disclaimer: This video is made for educational and entertainment purposes.
