Where is the largest rainforest in the world?

The largest rainforest in the world is the Amazon Rainforest, which spans approximately 5.5 million square kilometres (2.1 million square miles) across nine countries in South America, including Brazil, Peru, and Colombia. It is home to more than 390 billion trees and a staggering variety of species, making it one of the most biodiverse places on Earth. The Amazon plays a crucial role in regulating the global climate and is often referred to as the “lungs of the planet” due to its ability to produce oxygen.
