20% less oxygen to breathe for everything alive on earth

This is what the Amazon burning actually means in real time. People tend to think that oxygen will ALWAYS be there for them to breathe. This just isn't true. Oxygen primarily comes from plankton (diatoms) in the Ocean and secondarily from Trees and plants around the world.

If you cut down (or burn up) all the trees and rainforests then this oxygen is gone forever because the complete ecosystem is destroyed and likely cannot recover once it is burned away too much because of the type of soil there and various other factors.

So, this is NOT a temporary end to 20% of the world's oxygen but likely a permanent one.

diatoms in the ocean create another 40% of the world's oxygen but they are dying too from pollution and overheating of the oceans.

During photosynthesis, diatoms turn carbon dioxide into organic carbon and, in the process, generate oxygen. They are responsible for 40 percent of the organic carbon produced in the world's oceans each year.Jan 26, 2008

So, how long will it be before only people who lived before at 11,000 feet like in La Paz, Bolivia or Lhasa, Tibet at 12,000 feet are the ONLY ones who can breathe at sea level and everyone else is dead? This isn't a joke people. The Amazon burning with 72,000 fires is the permanent end of 20% of the oxygen generators on earth.
