Amazon rainforest is a tropical rainforest that covers most of the Amazon Basin of South America, with as much land as the contiguous United States. The majority of the forest is located in Brazil. It is home to 10% of the Earth’s animal and plant species, making it the most diverse ecosystem in the world. The Amazon rainforest is widely referred to as the 'lungs of Earth' because it releases huge amounts of oxygen and absorbs large amounts of carbon dioxide, a heat-trapping gas that is a major source of global warming. As such, Protecting the Amazon is critical to stopping climate change.
