On a Friday afternoon in September, I watched a climate strike in London as a part of the global protest by school students calling for action on climate change. The participants, mostly teenagers, held pictures of Greta Thunberg, the event's inspiration, as well as placards with slogans such as "Change the politics, not the climate" and "Make the earth cool again."
Since Thunberg staged her first protest outside the Swedish parliament in August 2018, youth all over the world have taken off from class to organize school strikes for the climate. On the largest strike on September 20, roughly four million in more than 150 countries took to the streets.
