Ozone depletion has been a concern for some time, and having taught college students about this for years I have come to realize many people do not know exactly what this means. And if they do, they are not certain how it occurs, and why we should have concern.
In fact, there are two ozone problems that are distinct from one another, one is ozone depletion and the other has to do with too much ozone. Both are of concern, but the second problem occurs in industrial areas, and the ozone is low to the ground. We need ozone, but not at the height of the air we breathe. Ozone as a pollutant is serious, but not what this article will address. Here we will concentrate on the ozone in the ozone layer, and what having less of it means.
