If pollution does not effect the planet, why is the ozone hole getting bigger?

We are changing the ph of the oceans from the carbon we add. I believe it is 100 ton's an hour. This comes from coal and hydrocarbons that we burn Forest fires etc. We are loosing coral reefs because the carbon is changing the ph of the ocean. I believe that it is the smog that we create that is causing the ozone to dissipate. We have problems to fix.
