The Amazon rainforest which is known as 'lungs of the Earth' produces 20% of the planet’s oxygen.

The fact-check reports published by Fact-Check Organisation and AP websites refutes the claim.

The fact-check reports published by Fact-Check Organisation and AP websites refutes the claim.The Fact Check Organisation states that the ocean accounts for about half of the oxygen production in the process of photosynthesis, which means about 6-9% of the world’s oxygen is from the Amazon forest and mentions that oxygen production is from plants and also from other photosynthetic organisms.

The AP website in their fact check article states that according to scientist Scott Denning, the oxygen of the planet comes from the ocean such as phytoplankton, which has contributed to breathable oxygen through the process of photosynthesis for millions of years.

The National Geographic article mention that Yadvinder Malhi, an ecosystem ecologist said that tropical forests are responsible for around 34 per cent of photosynthesis which occurs on land and thus Amazon forest generates around 16 per cent of oxygen on land.

National Ocean Service Report states that Ocean produces 50% of the air on earth.
