Sustainable living, gardening, and farming is based on an understanding of ecosystems and the study of relationships between organisms and their environment. It has been defined as an integrated system of plant and animal production practices that will last over time. Having a harmonious relationship with Gaia (Mother Earth) provides food for people, enhances the natural environment upon which the community depends, makes efficient use of resources, and integrates natural cycles that sustain economic viability as well as enhances the quality of life for the community as a whole.
