> The Amazon rain forest is not net zero because of animals. It's net zero (actually net negative last I heard) because humans are burning it to make way for agriculture.
According to the documentary "One Strange Rock", which I admit I have not fact checked, your statement is absolutely false. The documentary claims 100% of the oxygen produced by the Amazon rain forest is used up by the animals that live in it.
EDIT:
Also this PBS article backups the claim. https://www.pbs.org/newshour/science/no-the-amazon-fires-wont-deplete-the-earths-oxygen-supply-heres-why
"Forest plants produce lots of oxygen, and forest microbes consume a lot of oxygen. As a result, net production of oxygen by forests – and indeed, all land plants – is very close to zero."
This is cited in the documentary "One Strange Rock". That is the only data I have. I am trusting that the documentary is accurate, I have not fact checked the documentary.

One Strange Rock, a nature documentary hosted by Will Smith (stay with me) actually goes into this in some detail and I would definitely recommend a watch. https://www.imdb.com/title/tt7651892/
One Strange Rock documentary on Netflix makes the same claim.
Netflix has a pretty cool series called "One Strange Rock". You should watch it, they explain the Amazon's role well in one episode.
First of all oxygen is constant. Oxygen is currently not the problem. And it's a good thing that it's constant because we don't want more of it either.
The problem with Amazon is that on Earth it's all interconnected and while there's plenty of room for failure, there is a tipping point, scientists have only disagreed on where that tipping point is. Once we are there however we will no longer be able to stop the chain reaction.
