Does the Amazon provide 20% of our oxygen?
The basic gist of the article is found about 1/2 way in:<p>"First, the phytoplankton in the oceans also photosynthesise [...] Therefore in terms of TOTAL global photosynthesis, photosynthesis in the Amazon contributes around 9%. [...] Second, a bigger point that is often missed is that the Amazon consumes about as much oxygen as it produces."<p>This reminds me, as we should all be reminded on a regular basis, the bulk of the things you read in the popular press are at best skimming the surface and at worst outright misleading due to grabbing onto one obscuring factoid instead of the most important pieces of information. Per Gell-Mann, I only see this in tech and science reporting, but that makes me really unreasonably suspicious of political reporting, too.
