In 2017, at age 15, Margolin founded the youth climate action organization Zero Hour with
Nadia Nazar,
Zanagee Artis, and other youth activists. Margolin co-founded Zero Hour in reaction to the response she saw after
Hurricane Maria in Puerto Rico and her personal experience during the
2017 Washington wildfires. In September 2018, Margolin was part of a youth group that sued Governor
Jay Inslee and the
State of Washington over greenhouse-gas emissions in the state. The case was dismissed by a
King County Superior Court judge, who ruled the case to be political one that must be resolved by the Governor and the legislature. It has since been appealed
Washington Court of Appeals. In September 2019, she was asked to testify on a panel called "Voices Leading the Next Generation on the Global Climate Crisis" alongside
Greta Thunberg for the
United States House of Representatives. In 2020, Margolin published her first book, Youth to Power: Your Voice and How to Use It. In 2021, she started a Climate Justice Scholarship with the goal of allowing "budding activists such as herself to start tackling the climate crisis". == Personal life ==
