The “hole” in the ozone layer is sometimes invoked by those who downplay environmental concerns as an example of “sky is falling” warnings that never came to pass. It's an odd example. There's a simple reason ozone problems didn't come to pass: the world came together and agreed to phase out key ozone-depleting chemicals.
It’s a major success story, and one that should be remembered. As we consider the cost of dealing with ongoing environmental problems, it's worth considering: how much better off are we for the action we did take to preserve the ozone layer? Some scientists have now tackled this question.
Ozone gas in the stratosphere is enormously important for life on Earth. Ozone absorbs ultraviolet radiation emitted by the Sun, greatly reducing the amount that reaches the surface. It’s sunscreen for the planet, as UV causes skin cancer and sunburns. In the 1970s and early 1980s, it was discovered that compounds called chlorofluorocarbons (CFCs), commonly used as refrigerants and in aerosol sprays, were breaking down stratospheric ozone.
