Robin Greenfield (@RobinGreenfield) is an American environmental activist, adventurer, and humanitarian known for his bold, experiential campaigns that challenge consumerism and promote sustainable living. He has become widely recognized for living in radical simplicity to inspire others toward sustainability, self-sufficiency, and ecological awareness. Greenfield’s work has included biking across the United States on a bamboo bicycle while living off the grid, creating public displays from edible food found in dumpsters to expose food waste, and famously wearing every piece of trash he generated for 30 days to visually demonstrate consumer impact. In 2018, he undertook a yearlong project in Florida, during which he ate only what he grew or foraged himself—an effort to show what's possible outside industrial food systems. Rejecting modern excess, Greenfield has lived without a personal car, phone, or permanent home. He owns fewer than 50 possessions and donates 100% of his media income to grassroots causes. His campaigns have been featured by National Geographic, The Guardian, and TEDx, where he has shared his vision of a world rooted in harmony with nature.
