Unlike politicians, actors, and other media-trained personalities, Thunberg isn't trying to be anyone but herself. According to the Atlantic, that's what makes her so popular.
Thunberg's personality comes through in her direct, careful way of speaking. It comes through in her hair and her clothes — she wears a hoodie or t-shirt most often, and she usually goes with pigtails.
Another one of Thunberg's unique qualities is her age.
She is, truly, a teenager.
"Because we are so young, our perspective on the world, our perception of the world is so—is so, like, blank," she told the Atlantic. "We don't have that much experience. We don't say, Oh, we cannot change this because it's always been this way, which a lot of old people say. We definitely need that new perspective to see the world."
