The ozone layer is high above Earth. It helps protect people, animals, and plants from harmful ultraviolet light from the sun. But in the 1980s, scientists saw a large ozone hole over Antarctica each spring.
Susan Solomon, an American scientist, helped explain the problem. Some chemicals called CFCs could stay in the air for many years. High in the atmosphere, they released chlorine. This chlorine damaged ozone. In 1987, many countries made the Montreal Protocol. They agreed to stop using more of these chemicals. Solomon says the ozone layer is now showing recovery. The change will still take decades, but the ozone hole is forming more slowly than before.
