More than a million students are expected to walk out of class on Friday in a Global Climate Strike, with more than 800 climate strikes scheduled in the United States alone. Strikes are also being organized in another 150 countries around the world. In our New York studio, we speak to Amnesty International’s Secretary General Kumi Naidoo, who has urged school districts across the globe to allow students to walk out of school on Friday without facing punishment. In a letter, Naidoo, who is also the former executive director of Greenpeace, writes, “Children should not be punished for speaking out about the great injustices of our age. In fact, when it has fallen on young people to show the leadership that many adults who hold great positions of power have failed to, it is not young people’s behavior we should be questioning. It is ours.”
