Marina Silva, who will challenge Dilma Rousseff in a run for the Brazilian presidency, is known for many things. She unionized rubber tappers in the Amazon alongside legendary activist Chico Mendes in the 1980s. She became the country’s youngest female senator at 35. She cracked down on illegal deforestation as environment minister under former president Luis Inácio Lula da Silva—and then walked out in protest when she was unsatisfied with his policies in the Amazon.
