"I wanted to meet them and see how they managed to learn something which they were not used to," says Bruy, who lives in France. "Most of the people are not from farming families or anything."

Bruy has been photographing around Europe for the project since 2012, visiting some 15 encampments in his home country as well as in Romania, Spain, Switzerland, and Wales. He's focused on those who survive as sustenance farmers, by raising livestock, or hunting. Now he's holding a crowdfunding campaign because he'd like to extend the project to the United States, the country whose history he says inspired many of his subjects.
