Most of Earth's oxygen is produced by the Amazon rainforest.

REFUTED

Recorded sources
0 sources for · 6 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that most of Earth's oxygen is produced by the Amazon rainforest?

No. Multiple sources, including a FactCheck.org fact-check and National Geographic, state the Amazon's net contribution to Earth's oxygen is effectively zero, with estimates of only 6-9% of world oxygen production. The claim that most of Earth's oxygen comes from the Amazon is therefore false.
