[QUOTE="CornishTone, post: 6788805, member: 4147"] Bit of a misnomer that. At best, from a "lungs of the world" perspective, the Amazon accounts for a minute amount of the oxygen we breathe, barely above net 0%. The Amazons real value is that it holds a big ol' chunk of carbon in cycle and stops it being permanently released into the atmosphere. At worst however, when its going through a dry period like it is now, it actually releases huge amounts of carbon as the tree growth slows, CO2 use reduces and oxidation of the under-story/leaf litter takes hold which releases carbon. Not withstanding the fires, which make it considerably worse, the Amazon is releasing as much carbon as the US of A does each year. You can all fight over whether the dry period is as a result of natural cycles or man made climate change, but the Amazon is actually not helping at the moment. [/QUOTE]
