I remember being taught in middle school about the ozone depletion issue. Its funny you mention it, I wonder why they dropped it? remember being told not to use aerosol sprays because, it destroys the ozone.
However, less-well-known is that ozone depletion has been measured everywhere outside the tropics, and that it is, in fact, getting worse. in the middle latitudes (most of the populated world), ozone levels have fallen about 10% during the winter and 5% in the summer. Since 1979, they have fallen about 5% per decade when averaged over the entire year. Depletion is generally worse at higher latitudes, i.e. further from the Equator.
