How could a 15-year-old girl with a sign and a bunch of flyers really manage to influence an entire world?

Environmental journalist Anders Hellberg walked past the Swedish Parliament every day during Greta Thunberg’s first three weeks of school strike for the climate. He was the one who took the now iconic photo of Greta in a yellow raincoat with the hood pulled up – a photo that has since then been seen on book and magazine covers around the world.

This is his version of what happened during those dramatic weeks in August and September 2018. It’s a story about how a lone teenager defied the mockery of adults and planted the seed for the global movement Fridays for Future. Your Silence Is Almost the Worst of All is published with Greta Thunberg's approval.
