Like in ecological systems diversity is the cornerstone of the sustainable foods movement. There are many reasons and ways to live more sustainable lives. Being conscious of the stifling overhead inherent in mass-scale food production might lead you to buy more locally. The harsh treatment of animals in factory farms might mean you eat less meat. The pesticides and hormones in many corporate-farm crops might worry your healthy side beggin you to buy more organic foods. Put it all together, in myriad formats and varying degrees, and you have the Sustainable Foods movement.
