Sustainable animal farms
(Sustain-farm)

Sustainable agriculture is the practice of farming using principles of ecology, the study of relationships between organisms and their environment. It has been defined as "an integrated system of plant and animal production practices having a site-specific application that will, over the long term:

  • Satisfy human food and fiber needs
  • Make the most efficient use of non-renewable resources and on-farm resources and integrate, where appropriate, natural biological cycles and controls
  • Sustain the economic viability of farm operations
  • Enhance the quality of life for farmers and society as a whole.”

Sustainable Agriculture in the United States was addressed by the 1990 farm bill. More recently, as consumer and retail demand for sustainable products has risen, organizations such as Food Alliance and Protected Harvest have started to provide measurement standards and certification programs for what constitutes a sustainably grown crop.
