The Amazon rainforest is the largest in the world, spanning over 1.4 billion acres across nine countries. It contains an immense level of biodiversity, with over 40,000 plant species, 3,000 fish species, and over 1,000 species each of birds, mammals, amphibians, and reptiles cataloged. Many indigenous tribes still live in the Amazon and have diverse cultures and traditions, such as the Yanomami, Caboclos, and Witoto tribes. However, the Amazon and its extraordinary wildlife are increasingly threatened by deforestation, which destroys around 150 acres per minute and could eliminate the entire forest in less than 40 years.
