Our climate is in a crisis. 2019 saw atmospheric concentrations of greenhouse gases hit the highest level ever recorded in human history, and our window of opportunity to avoid disaster is quickly closing.

In the autumn of 2019, frustrated with the inaction of politicians, Jane Fonda moved to Washington, D.C. to lead weekly climate change demonstrations – dubbed Fire Drill Fridays – on Capitol Hill. There, she led thousands of people in non-violent civil disobedience, risking arrest to protest for action.

In What Can I Do?, Fonda’s deeply personal journey as an activist is weaved alongside interviews with leading climate scientists, and discussions of issues, such as water, migration, and human rights, to emphasise what is at stake. Throughout, Fonda provides concrete solutions and actions that everybody can take in order to combat the climate crisis in their community.

As Annie Leonard, Executive Director of Greenpeace US and Fonda's partner in developing FDF, has declared, "Change is inevitable; by design, or by disaster." The problems we face now require every one of us to join the fight. The fight not only for our immediate future, but for the future of generations to come.
