Ozone depletion does not have types. But it can be depleted in 2 ways. Natural way and man made.
The ozone hole is a natural occurrence. You cannot prevent it. You might keep it from starting sooner, have more ozone in it, or from lasting longer.... but you cannot stop it from forming once a year at each pole when it is late winter / early spring there.

There are two components. Man made substances and natural substances which deplete ozone.
