Blue-fronted amazon (Amazona aestiva) inside the house of Juarez Saw Munduruku, Cacique (chief) of village Sawré Muybu Indigenous Land, home to the Munduruku people, Pará state, Brazil. Brazilian Government plans to build 43 dams in the Tapajós river basin. The largest planned dam, São Luiz do Tapajós, will impact the life of indigenous peoples and riverside communities. Mega-dams like these threaten the fragile biome of the Amazon, where rivers are fundamental to regeneration and distribution of plant species and the survival of local flora. Renewable energy, such as solar and wind, holds the key to Brazil’s energy future.
