Teenage climate activist Greta Thunberg isn't letting a 73-year-old man's mocking of her get in the way of what she's trying to accomplish.
The 16-year-old is taking in stride the sarcastic comment President Trump tweeted following her fiery speech Monday at the United Nations. Thunberg made it clear in her address that she is angry at world leaders for not doing enough to curb climate change. "People are suffering, people are dying, entire ecosystems are collapsing," she said. "We are in the beginning of a mass extinction and all you can talk about is money and fairytales of eternal economic growth."
In response, Trump tweeted, "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!" Thunberg decided to run with it, and changed her Twitter bio on Tuesday to read, "A very happy young girl looking forward to a bright and wonderful future." That's how you troll the troll.
