The forest known as the "lungs of the Earth" is the Amazon Rainforest. This vast region is crucial for global ecology, producing about 20% of the world's oxygen and serving as a major carbon sink that helps regulate the Earth's climate. It spans across several countries in South America, including Brazil, Peru, and Colombia. The Amazon houses an incredible biodiversity, with millions of species of plants, animals, and microorganisms. Its preservation is vital, as deforestation and climate change threaten its health and the wider climate system affecting the planet.
