Climate activist, Greta Thunberg leads strike outside UN

Sixteen-year-old climate activist, Greta Thunberg has led a strike outside the United Nation Headquarters in New York.
The Swedish teen wants to raise awareness about the imminent dangers of climate change.
She arrived in Manhattan after a two-week journey across the Atlantic on a zero-carbon-emissions sailboat.
Thunberg has repeatedly called on young people to demand action against climate change.
Her protest is part of a series of youth events, culminating in the UN Climate Change Summit next month.
