The world’s largest rainforest is the Amazon Rainforest, which spans across multiple countries in South America, including Brazil, Peru, Colombia, and Venezuela. It covers approximately 5.5 million square kilometers and is renowned for its incredible biodiversity, housing an estimated 390 billion individual trees and millions of plant and animal species. The Amazon plays a pivotal role in the Earth's climate, producing about 20% of the world's oxygen and acting as a significant carbon sink. However, deforestation and climate change threaten its delicate ecosystem, making conservation efforts essential for maintaining this vital habitat.
