Answer to: How much oxygen does the Amazon rainforest produce? It's also home to about three million species of plants and animals and now, scientists are warning that the wildfires could serve as a dramatic blow in the fight against climate change. Aussie experts have reacted to the news. The amazon produces 20 % of the world's oxygen. The Amazon (just under half of the tropical forests) is around 16% of this, around 54 Pg of oxygen per year. Covering 5.5 million square kilometres (2.1 million square miles), the Amazon rainforest cycles a significant proportion of the Earth’s oxygen, absorbing large … According to The Atlantic, it produces approximately 6% of the oxygen that’s created by the photosynthetic organisms living on Earth right now..

But deforestation is bringing that percentage down drastically. 16% of the oxygen being produced on land today is from photosynthesis in the Amazon. Recently the Amazon biomass has been changing due to fires. In truth, the Amazon rainforest accounts for a fraction of oxygen production in the world.

Hence total oxygen production by photosynthesis on land is around 330 Pg of oxygen per year.

Rounded up, this is where the 20% figure comes from. During this process, carbon dioxide and water are converted into energy, releasing oxygen as a by-product. But here’s the catch: most of the oxygen available in the world does not come from photosynthetic organisms like trees. Although some reports have claimed the Amazon produces 20% of the world’s oxygen, it is not clear where this figure originated.
