“We should not have to sacrifice our education because the people in power don’t believe in science,” Isabella Johnson, the Illinois state lead organizer with the group U.S. Youth Climate Strike, said in her speech to those gathered in Federal Plaza at the culmination of the march. “It is not our job to save the world. It is the job of the adult generation, the people in power, but they’re not doing their job. We are being forced to act like adults to address the biggest threat to our future we have ever seen.”
