Nitrous Oxide Deadly to the Ozone

The funny/horrifying/sad thing is CFCs were inhibiting the impacts from NO! Sources of NO are chemical and organic nitrogen fertilizers and laughing gas. It has been estimated that the ozone has been reduced by ~6%. Unfortunately this somewhat small amount is concentrated at the poles and over Australia; while most of the world won't be directly impacted by this, Australians are experiencing increases in skin cancer.
