The notion that the Amazon region represents the “lungs of the World” or produces 20% of the world’s oxygen is pure mythology, and completely false.
But is still repeated years after years by mindless politicians, nutcase celebrities, innocently ignorant third-grade teachers, Third-World activists, rabid eco-Nazis, and the habitually clueless legions of tree-hugging media writers who have no idea what they are talking about.
Map showing the largest production of oxygen on LAND around the world. This map doesn’t show the phytoplankton production. Beer et al. 2010, Science
6CO2 + 6H2O —> C6H12O6 + 6O2
In other words, under normal conditions the Amazon forest is in a steady state. Oxygen is produced by photosynthesis and consumed by decay. If these were out of balance, then the mass of wood in the Amazon must change.
That means if the Amazon were to disappear today, instantly (e.g. we harvested all the wood and used it to build houses) then the oxygen and carbon dioxide in the atmosphere would continue on at the same level. Until, that is, the wood rots. Then the carbon dioxide levels would increase.
Except for the biomass decrease from human-caused fires, the biomass of the Amazon has not been changing. That means that no net carbon-dioxide is being removed from the atmosphere, so no net oxygen is being released from carbon dioxide.
Recently the Amazon biomass has been changing due to fires. When that happens, the wood and other carbohydrates in the trees combine with oxygen and produce CO2 and H2O (see photosynthesis equation above). The fires thus have major consequences for regional climate, the rich Amazonian biodiversity, air quality and human health, and some consequence for global carbon emissions (though still small compared to the amount being emitted by fossil fuel combustion in industrialised parts of the world).
But under normal situations, when the biomass of the Amazon is not changing, there is no net production of oxygen or carbon dioxide.

Realist - Everybody in America is soft, and hates conflict. The cure for this, both in politics and social life, is the same -- hardihood. Give them raw truth.
