"Luckily, the amount of oxygen already stored in the atmosphere is very large and 90% of all living biomass on Earth are oxygen-producing plant matter, whereas most of our oxygen comes from deforestation-proof oceans. Our oxygen reserves are so large, in fact, that if photosynthesis suddenly stopped and all 7 billion people were stuck on our planet with no other life forms and no fire, it would take about 50 million years to breathe up all the oxygen our atmosphere has stored."
- perfmode 3y agoBut fire though
- tourmalinetaco 3y agoHence “no fire”.
- qwytw 3y ago> 50 million years to breathe up all the oxygen our atmosphere has stored Surely CO2 level would reach unsustainable levels long before that? IIRC it would only need to increase to ~0.5% before air would become unbreathable for more than a few hours..
- Eddy_Viscosity2 3y ago> deforestation-proof oceans I don't know about that - ocean warming can be pretty effective at killing ocean life which is a form of 'deforestation'.
