Bioregionalism is an environmentalist movement based on the belief that political, cultural, and economic systems are more sustainable and just if they are organized by naturally defined boundaries (e.g., mountain ranges and rivers) instead of the artificially drawn boundaries that divide states and countries. According to Judith Plant, a leader of the movement: “Simply put, it means learning to become native to a place, fitting ourselves to a particular place, not fitting a place to our pre-determined tastes. It is living within the limits and the gifts provided by a place, creating a way of life that can be passed on to future generations.”
