Amazonia, often referred to as the Amazon Rainforest, is the largest tropical rainforest in the world, spanning across several countries in South America, including Brazil, Peru, and Colombia. It covers approximately 5.5 million square kilometers and is home to an incredible diversity of flora and fauna, many of which are not found anywhere else on Earth. The Amazon River, the second-longest river in the world, flows through this vast region, providing essential water resources. Amazonia plays a crucial role in regulating the global climate by absorbing carbon dioxide and producing oxygen, making it vital for environmental health and biodiversity.
