This month, "Trash Man," as he's been so fittingly dubbed, has worn all of the trash he has produced in a display of environmental activism. The 84 pounds of waste that have made their way onto his body over the past 31 days (a third less than the average American produces over the same time period) makes for a powerful portrait of overconsumption.
"It's all about finding a visual way to get people thinking about basic things: the food that we eat, the water we drink, the gasoline we put into our cars," Greenfield told mindbodygreen. "I always try to keep it fun and entertaining because I want to reach people who wouldn't usually care about these sorts of issues."
It's demonstrations like these that have turned Greenfield into a green visionary of sorts—but he wasn't always this way. Up until about five years ago, Greenfield didn't think twice about tossing a recyclable in the trash and he certainly wasn't one to turn down a plastic shopping bag. Documentaries, books, and other educational resources on the environment are what ultimately inspired him to make small changes like shopping at farmers market and using reusable bags. These eventually snowballed into a full-on zero-waste lifestyle.
