The modern system of agriculture, which depends on the consumption of large quantities of fossil fuel, will be forced to change to a system where the interactions between organisms and environment and matter cycling are properly used for 3 reasons: 1 the depletion of readily available fossil fuel resources, 2 the level-off of the growth and yield response of crops with the increase in the use of fertilizer, agrochemicals and big machinery, and 3 the degradation of the environment along with the consumption of fossil fuel and its derived agrochemicals.

目前，现代化的农业生产系统建立在大量燃料的消耗上，虽然西方发达国家在近半个世纪的发展过程已经证明这是一种见效快、经济产值高的生产方式，但是随着在世界范围内可持续发展观念的日趋重视，这种生产方式的弊端也逐渐地受到人们的注意。1原有农业生产方式需要消耗大量的燃料资源；2虽然肥料、农药和大型机械的应用不断提高，但近几年农作物的生产和产量表现出停滞状态；3燃料及其副产品的不断使用导致环境逐渐退化。
