Mackenzie Feldman is the founder & executive director of Herbicide-Free Campus. She graduated from UC Berkeley in Spring 2018 with a degree in Society and Environment and a minor in Food Systems. While attending UC Berkeley, Mackenzie and her teammate Bridget Gustafson created Herbicide-Free Cal after the two got herbicides banned from their beach volleyball courts and decided to expand the campaign to the rest of the campus. Upon graduating in 2018, Mackenzie expanded the campaign to the rest of the UCs, and then nationwide, and Herbicide-Free Campus was born. The campaign resulted in the entire University of California system going glyphosate-free; HFC also worked with the Protect Our Keiki Coalition to get all herbicides banned from every public school in the state of Hawaii. Mackenzie received the 2019 Brower Youth Award for her work with HFC. Mackenzie is also a Food Sovereignty Research Assistant for the FAO and a Food Research Fellow for Data for Progress, where she writes food and agriculture policy for the Green New Deal.
