> Quibble: Is it actually 'healing' if the depletion rate is decreasing? The hole in the ozone is still getting bigger. It's just getting bigger at a slower rate. Ozone is create in the upper atmosphere by UV light bombarding oxygen, among other mechanisms. The depletion rate is decreasing, but it's less than the creation rate, so the hole is healing. Even without chlorine, the ozone also decays back into O2 naturally.
