18. Who is Edward Snowden?

In June 2013, 29-year-old Edward Snowden bravely told the whole country that their government had been spying on them. And not only them, on the entire world. As a result, he's no longer allowed back in the U.S without facing treason charges and life in prison, or worse. But he risked all that because sometimes the truth is more important than the consequences. He also proved that sometimes, one person can change the entire world.
