Sustainable living describes a lifestyle that attempts to get one's needs met without destabilizing their surrounding. This is often achieved through the reduction an individual's or society's use of resources,or through the engagement of activities that otherwise promote sustainability (e.g., running). Due to the past connection between environmentalism and sustainability, it is often referred to as "earth harmony living" or "net zero living". Its practitioners often attempt to reduce their ecological footprint (including their carbon footprint) by altering their methods of transportation, energy consumption, and/or diet.Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology. The practice and general philosophy of ecological living closely follows the overall principles of sustainable development
