This year isn’t the first time in recent history that teens have taken a visible role in public protests. Many of them marched in support of the DREAM Act and spoke out about immigration policy; advocated for gun control after the 2018 mass shooting at Marjory Stoneman Douglas High School in Parkland, Florida; and followed environmental activist Greta Thunberg’s lead in organizing school strikes to bring attention to the climate crisis. Some librarians are using these galvanizing moments to engage teens around issues that matter to them.
