Approximately 20% of Earth's oxygen is a result of photosynthesis in the Amazon rainforest.

Explanation:

The Amazon rainforest is the world's largest rainforest and is located in South America. Its area is of 6.8 million km² and accounts for over half of the world's remaining rainforest areas.  

The forest covers areas in nine different countries: Brazil (60%), Colombia (10%) and smaller shares in Peru, Venezuela, Ecuador, Bolivia, Guyana, French Guiana and Suriname.

A popular myth is that the Amazon rainforest produces 20% of the world's oxygen. This myth has further fostered slogans that the rainforest is the "lungs of the world" and that the entire globe is dependent on its oxygen production. But in reality, the rainforest consumes about as much oxygen as it produces.
