Document Summary

A sustainable society meets the needs of the present generation without compromising the ability of future generations to meet their own needs. P1: a sustainable society does not use natural resources or produce wastes faster than they are regenerated or assimilated by the environment. Or reduce the ability of ecosystems to provide essential services to society. Natural processes that regulate conditions to make planet suitable for life. Something we get from the environment to meet our biological and economic needs and wants. The ability of the environment to absorb, detoxify, and disperse wastes to make them less harmful. P2: decisions that promote sustainability are consistent with the fact that human society is a system that is part of a larger system, the natural environment. Collection of parts that generate a regular or predictable pattern. A conceptual tool can draw boundaries anywhere. Examples: earth system, plant system, food system.
