One conception of sustainable living expresses what it means in triple-bottom-line terms as meeting present ecological, societal, and economical needs without compromising these factors for future generations.[8][9] Another broader conception describes sustainable living in terms of four interconnected social domains: economics, ecology, politics and culture. In the first conception, sustainable living can be described as living within the innate carrying capacities defined by these factors. In the second or Circles of Sustainability conception, sustainable living can be described as negotiating the relationships of needs within limits across all the interconnected domains of social life, including consequences for future human generations and non-human species.[10]
