  • Why the Amazon doesn’t really produce 20% of the world’s oxygen.

    The recent fires have brought up the old adage claiming the forest produce a large amount of oxygen, this article suggests a more realistic interpretation is in order.

    As the news of fires raging in the Amazon spread across the world last week, so did a misleading yet oft-repeated claim about the rainforest’s importance: that it produces 20 percent of the world’s oxygen.
    However, the figure—which has earned the forest the title “lungs of the Earth”—is a gross overestimate. As several scientists have pointed out in recent days, the Amazon’s net contribution to the oxygen we breathe likely hovers around zero.

    The processes that determine how much oxygen is found in the atmosphere on average occur over vast geological timescales and aren’t really influenced by the photosynthesis going on now, Denning explains in an article in The Conversation.
    Interesting - thanks for posting.

    Even though plant photosynthesis is ultimately responsible for breathable oxygen, only a vanishingly tiny fraction of that plant growth actually adds to the store of oxygen in the air. Even if all organic matter on Earth were burned at once, less than 1% of the world’s oxygen would be consumed.

      Lot of talk about how much oxygen it consumes, but how much oxygen does it produce?
