The best case scenario would be removing more CO 2 than we add to the atmosphere, we by removing the CO 2 then the Ozone would get better. We wouldn't have to worry about any more things about the atmosphere anymore. Then we would be able to contain more oxygen and probably have earth live longer.
The worst case scenario would be that there would be over flowed oceans and there wouldn't be anymore polar ice caps. Because they all melted and it starts extinction in the polar ice caps penguins and polar bears would go extinct.
