I've heard that the ozone hole is being regenerated. Is this true?

Yes, it's true. The ozone hole is a region of the atmosphere where there is a depletion of the ozone layer. It was first discovered in 1985 by scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). In recent years, researchers have found that the ozone hole is being regenerated due to natural processes such as wind circulation, temperature changes, and chemical reactions.
