The continent known for the Amazon rainforest is South America. The Amazon rainforest, often referred to as the "lungs of the Earth," spans several countries, with the largest portion located in Brazil. This vast tropical rainforest is renowned for its rich biodiversity, housing millions of species of plants, animals, and microorganisms, many of which are not found anywhere else on the planet. The Amazon plays a critical role in regulating the Earth's climate by absorbing carbon dioxide and producing oxygen. Conservation efforts are vital due to ongoing deforestation and environmental threats, highlighting the need to protect this crucial ecosystem.
