Sebastião Salgado traveled the Brazilian Amazon and photographed the unparalleled beauty of this extraordinary region for six years: the forest, the rivers, the mountains, the people who live there―an irreplaceable treasure of humanity. Salgado described the Brazilian Amazon as "the last frontier, a mysterious universe of its own, where the immense power of nature can be felt as nowhere else on earth. Here is a forest stretching to infinity that contains one-tenth of all living plant and animal species, the world’s largest single natural laboratory.”
