(1) it can provide the society with pollution-free, good taste, safe and environmentally friendly food, which is conducive to people's health and reduces the occurrence of diseases.
The massive application of chemical fertilizers and pesticides, while greatly increasing the output of agricultural products, inevitably leads to the pollution of agricultural products, leaving hidden dangers for the survival and life of human beings. At present, the great increase of human diseases, especially the great increase of all kinds of cancer, is closely related to the pollution of chemical fertilizers and pesticides. In the past, some places appear "talk about food color change" phenomenon. Organic agriculture does not use fertilizers, chemical pesticides, and other industrial and municipal wastes that may cause pollution, so its products are safe to eat and of good quality, which is beneficial to human health.
2. It can reduce environmental pollution and help restore ecological balance
At present, the utilization rate of chemical fertilizers and pesticides is very low. Generally, nitrogen fertilizer is only 20-40%. The adhesion rate of pesticides on crops does not exceed 10-30%. Such as a large amount of fertilizer into the lake caused eutrophication of water, affecting the survival of fish. Pesticides not only kill bacteria and pests, but also increase the resistance of diseases and insects, killing beneficial organisms and some neutral organisms, resulting in the rampant disease and insects, making the pesticide dosage more and more, more and more times of application, into a vicious cycle. Switching to organic farming can reduce pollution and help restore ecological balance.
(3) to improve the competitiveness of China's agricultural products in the international market and increase foreign exchange earnings.
With China's entry into the wto, the role of agricultural products in international trade is less and less regulated by tariffs, but the production environment, planting methods and internal quality control of agricultural products is more and more (so-called non-tariff trade barriers), only high-quality products can break the barriers. Organic agricultural products are internationally recognized as high-quality, pollution-free and environmentally friendly products. Therefore, the development of organic agriculture can improve the competitiveness of China's agricultural products in the international market and increase foreign exchange income.
4. It is conducive to increasing rural employment and farmers' incomes and raising the level of agricultural production.
Organic agriculture is a labor-intensive industry and a systematic project, which requires a large amount of labor input and a large amount of knowledge and technology input. The price of organic agricultural food on the international market is usually 20- higher than the general product, and some are more than twice as high. Therefore, the development of organic agriculture can increase rural employment, increase farmers' income, improve agricultural production level and promote sustainable development of rural areas.
