Youth Ambassadors

Nika Moeini


Policy change starts with making our voices heard. Young people will not only shape the future, but we will shape the present through our actions! We are leaders today, and must act on the greatest threat of our time: climate change.

Morgan Janowicz

Green REV Institute


We are on the edge of a climate catastrophe, yet we continue to conduct business as usual, afraid to make often radical but necessary decisions and ignore the science that ruthlessly shows us the reality in which we all find ourselves.

Brunna Sachs


If the world switched to plant-based food we wouldn’t have to deal with so many problems in the future! What we choose to put on our plates directly affects ecosystems, humans and the climate. Make the change now! The planet, animals and future generations thank you.

City Ambassadors 

Ambaree Majumder

Social Entrepreneur, Speaker and Educator, Singapore

Read Ambaree's bio

Ambaree Majumder is a Social Entrepreneur, Speaker and Educator in the field of Plant based Nutrition as well as Food Sustainability from eCornell.

She advocates eating a diet rich in plants through her talks workshops that are based on scientific evidence on why it is crucial that we gradually move to a plant based lifestyle for better human health and environmental sustainability. She has spoken at schools, university, corporate organisation and on several global platforms in countries like the USA, Australia, Malaysia, India, the Philippines and Singapore.

She is also a member of Rotary Club of Marina City in Singapore and leading the region of Singapore in their efforts towards protecting the environment. She is the co-chair of a task force called Plant-Rich Diet under Environmental Sustainability Rotary Action Group.

The fact that we can still prevent a climate catastrophe to a large extent just by modifying our eating habits is ray of hope for us and our future generations. Although it seems like a simple solution, the journey to achieve it might be one of the most difficult ones. I believe that it is possible only through persistent awareness campaigns and policy amendments. Both of these goals seem within our reach through the Plant Based Treaty.

Health Ambassadors

Dr. Shireen Kassam

Founder and Director of Plant-Based Health Professionals UK

The UK is slowly coming to the realisation that a shift away from animal agriculture is indeed necessary, it is not happening quickly enough. It’s therefore down to us as healthcare professionals to lead the way. This is why we are proud to be endorsing the Plant Based Treaty.

Media Ambassadors 

Robbie Lockie

they / them

Digital media expert, co-founder and co-director of
Plant Based News

Read Robbie's bio

Robbie Lockie is a digital media expert and influential figure within the global vegan movement. They are perhaps best known for being the co-founder and co-director of Plant Based News

Lockie was born in Zimbabwe, Africa, and started a career in digital design before relocating to London, England, in 1999.

Like most people, Lockie grew up eating meat – but they decided to try out a plant-based diet in 2013 after experiencing health problems. The switch had a hugely positive impact on them, which led Robbie to research other benefits of veganism. It was then that their eyes were opened to the immense suffering of farmed animals. 

Veganism has since become a major part of Robbie’s life. They founded Plant Based News alongside Klaus Mitchell in 2017, and the digital media platform has become the world’s leading source of vegan news. It has 80 million impressions a month, and almost 3 million followers on social media. 

Robbie is also the founder of the globally celebrated initiative World Plant Milk Day. They have produced a number of videos for animal rights organisation Viva!, including The Dairy Industry’s… TRASH and Swine. The latter explores antibiotic-resistant superbugs on factory farms.

Through all their valuable work, Robbie draws attention to how a vegan lifestyle can benefit animals, the environment, and our health. They also disseminate much-needed information that mainstream media often chooses to ignore. Truly “disrupting the conventional narrative.”

Care Home Ambassadors

Bill and Pat Russell

On February 1, 2023, Bill and Pat Russell happily agreed to “join the diplomatic corps” and become Plant Based Treaty ambassadors for care homes. Their daughter Regan Russell, who was tragically killed on June 19, 2020 by a pig transport truck going to Fearmans slaughterhouse across the street from the coffee shop they are sitting in the above video, would be very proud of her beloved parents. At 92 years young, Bill and Pat are continuing her activism to build a kind, vegan world.

Films (producers of Cowspiracy and What the Health), the Humane Party USA and the Animal Protection Party, Canada. He lives with his wife, Mélanie Bernier and five rescue cats on the small-scale veganic farm, La Ferme de l’Aube Accueil ( in Boileau, Québec. He has been growing his own food and homesteading for over twenty-five years and became a professional full-time organic farmer in 2005. From 2010-2014 he worked and consulted on eleven, organic and permaculture farms throughout Hawaii, Mexico, Central America, South America and Québec before settling at his current home in 2014.

As a naturalist he has conducted field studies as a ‘citizen scientist’ logging more than 10,000 hours of field work with theNational Audubon Society, National Park Service, US Fish & Wildlife Service, Nature Conservancy, Birds Canada and the Arizona and Québec Breeding Bird Atlas’s.


Human beings’ current practices of speciesism, the way we are dominating the planet, must come to an end.  As a veganic farmer and activist I have dedicated my time to show that there is a more compassionate way to walk on our collective earth. City by city, state by state, nation by nation we can live together harmoniously with each other and the natural world. We can end animal agriculture forever and transition to a 100% plant-based agricultural system. The Plant Based Treaty has my endorsement for they seek to enact on these principles whole-heartedly.
