Ecosharing is an environmental ethic for people to live by: that their own impact on the Earth’s biosphere be limited to no more than their own fair ecoshare. The term seems to have been first used by G. Tyler Miller, Jr. in the 1975 edition of his Living in the Environment text.[1] The 1990 book Coming of Age in the Global Village sought to quantify an "ecoshare" by linking it to average world per capita income and energy use.[2] A more modern approach might extend this by also including one's carbon footprint. However it is gauged, an ecoshare is determined by overall assessment of the human impact on the biosphere, computer models of its future condition, and necessary limits imposed by sustainability criteria.
