At just 16, Sweden's Greta Thunberg has not only taken on impending ecological collapse, she's also made history as the youngest ever to be named Time magazine's Person of the Year.
The climate change activist's gut-punching speeches have been a regular feature on nearly every social media platform, none more so than the one she presented at the UN Climate Action Summit earlier this year.

In all-too-typical Trump fashion, the world leader took to Twitter to troll the Swedish teen after her UN Climate Action Summit speech.
"She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!" He wrote, for which he received intense backlash on the platform.
But instead of being offended by the president's diss, the teen simply updated her bio with the shady Tweet.
Has the Twitter sparring king finally picked on someone his own size?
Her mom and dad are entertainers
The family have come a long way since their apprehension about Greta's activism, and along with their younger daughter, Beata, have co-written a book titled Scenes from the Heart.
The family's forthcoming title Our House Is on Fire: Scenes of a Family and a Planet in Crisis is set to published next year.
She never travels by plane
The teen has been vocal about her no-fly policy, preferring to travel by boat instead. During an appearance on the Daily Show, she explained this is due to "the enormous impact aviation has on the climate."
She writes her own speeches
Few people have the ability to deliver the kind of gut-punching speeches that seem to come so naturally to the 16-year-old, and she's previously confirmed the words are her own.
"There is no one 'behind' me except for myself... And yes, I write my own speeches. But since I know that what I say is going to reach many, many people I often ask for input," she commented in a Facebook post addressing rumours that her speeches are not her own.
