"It's Our Future": Meet the Youth Activists Behind Fridays for Future Movements in Uganda and Chile

In Spain, the 16-year-old Swedish climate activist Greta Thunberg has arrived in Madrid to take part in today's strike as well as a major march set for 6 p.m. local time. Greta began the climate strike movement last year when she started skipping school every Friday to stand in front of the Swedish parliament, demanding action to prevent catastrophic climate change. Her protest spread, quickly going global. We speak with two youth climate strikers: Hilda Flavia Nakabuye is the founder of Fridays for Future Uganda and Angela Valenzuela is a coordinator with Fridays for Future in Chile, where this year's U.N. climate summit had been scheduled but massive protests against neoliberalism forced the Chilean government to cancel the talks.
