Thousands of schoolchildren are leaving classrooms in over 100 countries around the world today, in a “school strike for climate” demanding immediate, urgent action to curb global warming. In the U.S., students organized some 400 protests in all 50 states. This is 13-year-old activist Alexandria Villaseñor, who helped organize today’s walkouts in New York City.

Alexandria Villaseñor: “Civil disobedience is called for, because there hasn’t been enough action in the climate conversation. World leaders aren’t enacting the right policies and laws that need to happen to keep us below 1.5 degrees.”
