Atmospheric CO2 is fungible. We can theoretically produce less CO2 today to make up for the excesses of the past. (Not saying this is easy, or that humanity would have any detectable inclination to actually stop producing CO2.) Destroying the habitat of thousands of species is not fungible. It can never be restored.
