Good question. Humans have been making species extinct since the Ice Age. Mammoths, sabre toothed tigers, cave bears, brown bears, red elk, gigantopithecus, neanderthals, you name it, we've been wiping them out since we were in loinskins...
If you study a comparison of the levels of per capita pollution with the per capita income, you find that pollution per capita is at its highest with a per capita income of about $10,000.00. After that point the pollution per capita will drop off significantly down to what looks like some sort of a limit at abou 35-40 percent of the maximum, at around the $20k per capita level. Since there aren't any societies that exist with higher per capita income, it is impossible to extrapolate, since per capita income in a society seems to behighly dependent on the technology level of the society. We don't know what sort of pollution reduction technologies may be developed in the future, although controllable limited nanotech may be considered to be capable of being a 100% reducer of pollution.
