In August of 2018, Greta Thunberg a 15-year-old student in Sweden starts a school strike for the climate. Her question for adults: if you don’t care about her future on earth, why should she care about her future in school? Within months her strike evolves into a global movement. Greta, a quiet Swedish girl with Asperger’s syndrome is now a world famous activist. The team behind GRETA is with her from the start, and is sailing with her across the Atlantic in time for the UN Climate Week in September 2019.
