Teenage climate activist Greta Thunberg has been named TIME Magazine’s 2019 Person of the Year. Notably, Thunberg, 16, traveled by sailboat, La Vagabonde, to New York City to deliver a grave message to the United Nations, thus beginning her school strike to save the climate.

“We can’t just continue living as if there was no tomorrow, because there is a tomorrow,” she told the magazine, “That is all we are saying.”

Thunberg put the fear of God in some of the world’s top decision makers, during her emotional address at the UN. “I shouldn’t be up here. I should be back in school on the other side of the ocean, yet you all come to us young people for hope. How dare you. You have stolen my dreams and my childhood with your empty words, yet I am one of the lucky ones,” Thunberg said in her address.

She continued, “People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction and all you can talk about is money and fairytales of eternal economic growth. How dare you.”

It’s been 16 months since that day. Since then, Thunberg has been inspiring other young people to organize their own climate strikes across the globe. She’s traveling across the globe on her tiny boat to address government leaders, policymakers, and young activists who are just like her.
