Episode 501: Dr. Trent Grassian on His Research into Vegan Campaigns

By Jasmin and Mariann — August 17, 2019

This week, Mariann talks to Dr. Trent Grassian about his recent evidence-based research into seven UK-based meat reduction and vegan campaigns. He talks about his discoveries about the effectiveness of meat reduction, how motivation to save animals is a more powerful motivator than the health motive, the lack of diversity he discovered in vegan and animal rights organizations, and much more.

Dr. Trent Grassian recently completed his PhD, after earning a Master’s in Public Administration. Trent conducted research with non-profit organisations promoting meat reduction and veganism, in the largest study of its kind and has given presentations all over the world about the project. He is also a passionate intersectional advocate and helps run London Vegan Voices, a London-based pro-intersectional vegan group, and the on-line group, Vegan Researchers & Enthusiasts. In a former life, he worked as a Special Needs Education teacher in California for half a decade and helped found a local volunteering non-profit branch. He is a passionate animal advocate, who has volunteered with animals on three continents and spends most of his free time helping others adopt cruelty-free cooking skills and hanging out with his dog, Rigby.

In the intro to this episode Mariann and Jasmin talk about Jasmin’s move to West Hollywood and all the vegan food near her, HappyCow in the age of the Impossible Whopper, and the people giving them hope in the age of climate crisis. Later in the show, Mariann brings us some Rising Anxieties about “vegetarian butchers” and more.
