What is the purpose of the development of circular agriculture?

Development of circular agriculture, to realize the following three aspects of change: First, from the production function to take into account the coordinated development of ecological and social change. The development of circular agriculture, to change the current production of light environment, heavy economy light ecological, heavy quantity light quality of thinking, focusing on both the quantity to meet the supply, but also focus on the quality of security; focusing on both the production efficiency, but also focusing on the construction of the ecological environment. Secondly, from the one-way resource utilization to the circular transformation. Traditional agricultural production activities as "resources - products - waste" single program linear growth model, the more output, the more resource consumption, waste emissions are more, the ecological damage and pollution of the environment is more serious. Cyclic agriculture to extend the industrial chain as the main line, to promote the single program agricultural growth model to "resources - products - renewable resources" cycle of comprehensive model change. Thirdly, we should change from the rough and high consumption type to the saving and efficient technology system.
