The video addresses the misconception that the Amazon rainforest produces 20% of the world's oxygen. It clarifies that while the Amazon is crucial for biodiversity and climate regulation, it does not significantly impact global oxygen levels. Most oxygen comes from oceanic photosynthesis, and the oxygen produced by rainforests is balanced by consumption through decomposition. The video emphasizes the real concerns of deforestation and forest fires, which harm ecosystems and increase CO2 levels, but do not threaten oxygen supply.
