The world's largest rainforest is the Amazon Rainforest, primarily located in Brazil, but also extending into Peru, Colombia, and several other South American countries. Covering approximately 5.5 million square kilometers, it is renowned for its biodiversity, housing millions of species of plants, animals, and microorganisms, many of which are found nowhere else on Earth. The Amazon plays a crucial role in regulating the global climate, producing significant amounts of oxygen and serving as a carbon sink, while also supporting the livelihoods of countless indigenous communities.
