Sunday's presidential elections in Brazil will prove to be historic, with the country's first black presidential candidate on the ballot.

And if she's elected, Silva would be the world's first Green party president. In 1984, Silva helped found her region's first workers union to protest deforestation of the Amazon.
In 2007, the United Nations Environment Programme named her one of its "Champions of the Earth."
So with her long list of accomplishments and incredible backstory, why haven't we heard more about her?
For one, her race doesn't seem to be as noteworthy among Brazilians. A press manager for Silva's party told The Christian Science Monitor, "We have the aura of living in harmony, despite there being so much prejudice. It’s part of our education as Brazilians."
But Silva's campaign hasn't been free of controversy.
Silva revoked her earlier support of same-sex marriage, a move that lead to the resignation of her campaign's gay issues coordinator. Silva called the move a "correction of an earlier mistake."
Although earlier polls said Silva could take the election from incumbent President Dilma Rousseff, The Wall Street Journal reports Rousseff is expected to take 37.3 percent in the first round of elections compared to Silva's 22.5 percent. Rousseff is also expected to win the election if a runoff election occurs.
