In August 2018, a 15-year-old girl from Sweden, Greta Thunberg, started skipping school to protest outside the Swedish Parliament about the lack of action on climate change. Since then, she has become a global figurehead in the fight against climate change. In April 2021, a three-part documentary series titled “Greta Thunberg: A Year to Change the World” premiered on BBC One.
