Greta Thunberg aims to inspire change with new docuseries

Activist Greta Thunberg took a gap year from high school in 2019 to help spread awareness about climate change, and that journey is documented in her new series “Greta Thunberg: A Year to Change the World.” The three-episode docuseries will premiere on Earth Day (April 22) at 8 p.m. EST on PBS in the U.S. and on BBC Earth in Canada.
