Amazon Rainforest
The largest tropical rainforest on Earth/Landforms
The Amazon Rainforest spans nine countries and contains about 10% of all species on Earth. It produces roughly 20% of the world's oxygen through photosynthesis and stores an estimated 150-200 billion tonnes of carbon in its biomass. The forest is so dense and vast that isolated indigenous groups still live within it who have never made contact with the outside world.
