In 1974, two chemists made a shocking prediction: that common chemicals used in spray cans and fridges could one day destroy the ozone layer — the thin shield that protects every living thing on Earth. Few believed them. But a decade later, satellite data and Antarctic measurements proved they were right. The ozone hole had become a terrifying reality.
This video tells the incredible story of how science, politics, and public pressure collided — and how, against all odds, the world came together to fix it. From NASA’s data error to the 1987 Montreal Protocol, from industrial denial to global cooperation, the fight to save the ozone layer became one of humanity’s most successful environmental turnarounds.
Today, the ozone layer is healing. But its story carries a warning: our actions can destabilize the planet — and only collective effort can restore it.
