The Amazon: The Lungs of the Earth

The Amazon, known as the lungs of the Earth, produces 20% of the world's oxygen. Despite covering only 2% of the Earth's surface, it is a vast and diverse ecosystem. The Amazon spans 40% of South America, with 60% in Brazil, and is the largest tropical rainforest. It plays a crucial role in the water cycle, releasing more water vapor than the Amazon River discharges into the Atlantic. The rainforest is home to a wide array of wildlife, including dangerous creatures like poison dart frogs and black caimans. It hosts 10% of known species and numerous indigenous tribes, some uncontacted, highlighting its rich biodiversity and cultural significance.
