No real impact would be to deny the fact that climate change, environment encroachment and pollution are not playing a part in the current mass extinction event taking place.
And whether we have 300pmm or 475pmm will not make a lick of difference to our survival chances. If you look at the past four eco censuses you'll see a a near 30% decline in recorded bio-mass every cycle. We really don't have to worry about sea levels at the end of the century...
We have had a very real impact, but the planet was once nearly entirely covered by a single species of fungus, so its all cogs and wheels...
