Amazon is the source for 20% oxygen. Brasil's president thinks climate change is a myth (just like every conservative head of state these days)

It's scary how much he could damage the world by flattening the Amazon

I don’t think that is accurate. Most of the oxygen produced by the Amazon remains local and is consumed by local fauna. The rest of the world is almost entirely dependent upon local systems and oceanic diatoms for oxygen.

There are many other serious environmental concerns at stake, but not oxygen loss.

What? This doesn't sound plausible at all. Do you have a citation for this claim?

This paper suggests quite the opposite. https://www.sciencedirect.com/science/article/pii/S209592731...

There is a large HN discussion about it: https://news.ycombinator.com/item?id=20789771

Makes sense that regions would have a local source of O2.

But it will have some impact on CO2 right?
