I think the charitable interpretation of the use of the “20% of the earths oxygen” statistic (as the article states this is probably more like 9% of earths photosynthesis) is not about an imagined fear of oxygen depletion, but drawing attention to how massive and important an ecosystem the Amazon is.

That's likely, but we could pretend it's 80% with the same reasoning - and it has an even larger effect with regard to drawing attention to the importance.

I am not excusing the statistic. I think people should be accurate. To me the correct statistic is just as compellingly.
