Bolsonaro is possibly the most dangerous world leader at the moment, deforestation has shot up under his rule, in June it was up 88% year on year in July up 278%. Those figures were reported by Brazil's national space research institute, the INPE, the head of the INPE has since been fired for reporting these stats.
He doesn't care, this was his message to Merkel this week, when Germany announced it would with hold funds for Amazon projects because of the huge spike in deforestation.
"I would like to give a message to the beloved Angela Merkel, take your dough and reforest Germany, OK? It's much more needed there than here."
Some of these fires are natural and do happen every year, but this year there is a huge drought in Brazil, also more are being started by farmers, who think it is now fine to do it as the President is behind them. We are not yet at the peak of the fire season, that's in September - this is only going to get alot worse.
The biggest issue is not how much Oxygen it produces or uses up, it's carbon. Photosynthesis takes CO2 out of the air and releases Oxygen while storing carbon in the plant/tree which is used for growth. Burning that means all that Carbon is released back into the atmosphere. On top of that the cleared land is generally used for cattle farming, another massive source of CO2.
This fire terrifies me.
