How is the ozone decreasing?

Question

I dont want causes or effects.

I was just wondering how the actual ozone decreases

Answer 1

Ozone is made of 3 ozygen molecules. Things like CO2 to up into the stratosphere, in which the middle is the ozone layer. The CO2 breaks apart the ozygen molecules and they fall away. This makes the big hole in the ozone. But, fortunately, we have found that ozone slowly replenished itself.

Answer 2

Its not. Thinning of the ozone layer is a seasonal event. There has been a net increase in ozone since the banning of CFC's in the late 80's. Stop referring to old data.
