The Amazon represents more than half of the Earth’s rainforests.
Spanning nine South American countries and 2.5 million square miles (roughly the size of the 48 contiguous United States), the Amazon represents over half of the world’s remaining rainforest.
It’s the world’s largest rainforest, with the Congo Rainforest and the Valdivian Temperate Rainforest coming up next. Tropical rainforests have been called the ‘world’s largest pharmacy’, because over one quarter of natural medicines have been discovered there.
