From Australia to Afghanistan, South Korea to Senegal, millions of people joined together in solidarity this past week to demand action on climate change. Youth have mobilized and planned strikes in over 150 different countries, according to The Global Climate Strike website. Greta Thunberg, the sixteen year old leader of Fridays for the Future, has been striking every Friday since August 2018. This week, she asked youth across the world to join her by walking out of school and work to demand action on the current climate crisis. The strike was strategically planned to precede the United Nations General Assembly and the Climate Action Summit this upcoming week. Thousands of miles away, the movement inspired action in Madison, Wisconsin, where protesters showed up en masse to show their support.
