The Amazon, Brazil

 The world's largest rainforest spans more than 2.3 million square miles (6m sq km) across Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Suriname and French Guiana, and is one of the greatest wonders on the planet. The sprawling jungle is thought to contain 10% of the world's known species, and there are still parts unexplored by modern society. Entire communities of people live in the rainforest and remain isolated, despite the encroachment of modern man by way of deforestation and tourism in some parts. The Vale do Javari is one of the largest indigenous territories in Brazil, and it hit headlines in 2018 when drone footage caught images of one tribe walking through a clearing in the forest. Some of the worst fires in years devastated parts of the forest in 2019 and had a devastating impact on wildlife and the lives of indigenous communities. Reports indicate that the affected areas could take centuries to recover. But copious amounts of wildlife still thrive within these trees for now. Animals such as golden lion tamarin and capybaras live under the dark cover of the forest canopy and all sorts of fish, including electric eels, swim in the rivers.
