Teen activist Autumn Peltier is especially known for her face-to-face meeting with Justin Trudeau, during which the girl berated the Canadian Prime Minister for his stance on water protection.

Axar.az reports citing sputniknews.com.

13-year-old Autumn Peltier, who gained international recognition for promoting clean water for indigenous communities in Canada, will address world leaders at the United Nations (UN) in March.

She will speak at the UN General Assembly in New York for the declaration of the International Decade for Action on Water for Sustainable Development.In Canada, where American Indian tribes are referred to as 'First Nations', Autumn lives on Wikwemikong First Nation tribal land in the remote wilderness of Northern Ontario. Once praised for its environmental track record, Ottawa is now routinely condemned as a top polluter for its use of fracking to produce oil for export.

It was an apparent reference to Trudeau's support of a spate of pipeline projects, which were harshly criticized by indigenous environmental activists.

Peltier started to advocate for water protection when she was eight and has been in attendance at an array of major international gatherings since then.

Last year, she attended the Children's Climate Conference in Sweden, and in 2016, she was the only Canadian to be nominated for the International Children's Peace Prize – an award that she failed to win.

She told the BBC that she had no regrets about it because "this award isn't going to stop you from doing the work you're doing" and that she will keep "doing my work until the water's clean."
