The country with the largest tropical rainforest is Brazil, primarily within the boundaries of the Amazônia region. The Brazilian rainforest is recognized as a vital ecosystem, rich in biodiversity, housing countless species of plants, animals, and microorganisms. The Amazon Rainforest plays a crucial role in regulating the Earth's climate and is often referred to as the "lungs of the planet" due to its capacity to produce oxygen and absorb carbon dioxide. Protection and conservation efforts are critical to address deforestation and preserve this essential environment.
