Mother of five Antonia Melo coordinates the Movimento Xingu Vivo Para Siempre, a grassroots mobilization to oppose the construction of the Belo Monte Dam in Brazil. If completed, the project would divert the flow of one of the Amazon River’s most important tributaries and devastate thousands of acres of rainforest, displacing 20,000 people and threatening the livelihoods of Brazil’s Indigenous peoples. Melo’s tireless work to coordinate the efforts of 150 different grassroots groups has made her indispensable to the resistance for over two decades. Photo credit: Amazon Watch
