The Amazon Rainforest is primarily located in Brazil but also extends into several neighboring countries, including Peru, Colombia, Venezuela, Ecuador, Bolivia, and Guyana. It is the largest tropical rainforest in the world, covering over 5.5 million square kilometers. The Amazon is renowned for its rich biodiversity, housing millions of species of plants, animals, and microorganisms, many of which are found nowhere else on Earth. The rainforest plays a critical role in regulating the global climate, absorbing carbon dioxide and producing a significant portion of the world's oxygen. Its preservation is vital for environmental sustainability and combating climate change.
