The first is the slow and constant deterioration of the amount of ozone in the earth's upper atmosphere at a rate of about 3 percent per decade. The second is the larger but seasonal decrease in the level of ozone in the atmosphere especially in the earth's Polar Regions, commonly called an ozone hole.
