Leave No Trace (LNT) is a set of environmental ethics and outdoor practices designed to minimize human impact on natural spaces. Originating in the United States during the 1960s and 1970s, LNT principles were developed in response to the increasing popularity of backcountry recreation and the visible damage caused by visitors. The system was formalized by the Leave No Trace Center for Outdoor Ethics, a nonprofit organization that provides education, training, and advocacy. The framework is built on seven core principles: plan ahead and prepare, travel and camp on durable surfaces, dispose of waste properly, leave what you find, minimize campfire impacts, respect wildlife, and be considerate of other visitors. These guidelines are widely applied in national parks, wilderness areas, and outdoor events to preserve ecosystems and cultural sites. LNT has also been adopted by large-scale gatherings such as @Burning Man, where its @Ten Principles are integrated into community norms to protect the desert environment. The ongoing relevance of Leave No Trace reflects a global effort to balance human presence with @Ecological Stewardship.
