What percentage of Earth's oxygen is commonly but inaccurately attributed to the Amazon rainforest?
Answer
20%
While often cited as producing 20% of Earth's oxygen, the Amazon's net oxygen production is actually near zero because the forest uses much of the oxygen it produces.
💡 Did you know?
Earth's excess oxygen actually comes from marine algae in the oceans, not from rainforests. However, the Amazon is crucial for absorbing 15% of atmospheric CO2.
