Greta Thunberg, the soft-spoken Swedish teenager who became a global conscience for climate change and environmental activism, has been named Time magazine’s Person of the Year for 2019. "She became the biggest voice on the biggest issue facing the planet this year, coming from essentially nowhere to lead a worldwide movement," Time editor-in-chief Edward Felsenthal said, adding that Thunberg is the magazine's youngest choice ever to be named Person of the Year. He also said that Thunberg "represents a broader generational shift in the culture" — with youth standing up for what they believe in — from Hong Kong to Chile. "Young people are demanding change, and urgently," Felsenthal said. "She embodies youth activism."
