Isabella Tree lives with her husband Charlie Burrell in West Sussex amid what she terms “a pioneering rewilding project.” Together, they have helped jumpstart a “rewilding revolution” in Britain. What does that look like? For Isabella and Charlie, it means farming. Isabella knows that human society continues to pour pesticides into natural ecosystems. She seeks to eliminate these environmental hazards and cultivate wildlife in her own backyard. Isabella hopes we can all start to notice living things more often. “Wilding,” a UK documentary film based on her book “Wilding: The Return of Nature to a British Farm,” will be released in several European countries this summer.
