Scientifically, I see what you are saying. Not really making oxygen out of CO2.I believe NASA has stated that there are fires but they are actually down from previous years.
As far as "carbon cleanser". That's not accurate either. The Amazon is a carbon sequestration zone. There is no cleansing. It's just holding carbon and not emitting it. Unless of course it's on fire then carbon is released.
As far as fake news. I think it's sad when news organizations push any agenda. We live in a time where fact checking is as easy as it ever was and people as well as news agencies willfully choose not to.
I believe the word cleanse commonly refers to taking in Carbon Dioxide and producing Oxygen. (photosynthesis) Rather a nice gift exchange, I would say. This to the tune of about 20% of the world's oxygen.
I was not able to find evidence of your NASA findings but did find the following quote from a NASA article: Brazil’s space research center, the National Institute for Space Research, which monitors fire activity with satellites, said the number of fires in Brazil between Jan. 1 and Aug. 20 rose by 84% from the same period in 2018, with more than 70,000 fires detected in Brazil’s Amazon rainforest so far this year — the highest number since records began in 2013.
Thank you for checking the accuracy of my quotes. I do not want to emit fake news.
