Sebastião Salgado grew up in Minas Gerais, Brazil—a place full of beautiful rainforests. He left home to become a photographer, only to return to his hometown, in 2000, to discover that only 0.5% of forest remained. Salgado founded Instituto Terra in 1998, planting more than 2 million seedlings of more than 290 species of trees and plants. In 20 years, 1,500 acres of rainforest have been recovered, and 293 species of plants, 15 reptile species, 172 bird species, 15 amphibian species, and 33 mammal species have returned. Don’t let anyone tell you one person can’t change the world.
