On November 26, 2019, tens of thousands of German farmers protested against the government's increasingly stringent agricultural environmental regulations.The regulation of agricultural environment in EU is very strict, and these policies will undoubtedly increase the cost which farmers bear. In the era of globalization, if other countries' agriculture does not have such high standards, German agriculture will not be able to compete with them. This is the background of the German farmers' protest.All countries begin to set higher and higher environmental standards for agriculture. The improvement of environmental standards is a good thing, but its span of policy is too large, sometimes it turns too fast. The speed is easy to cause great social and economic problems. China is no exception.Whether in developed or developing countries, farmers are vulnerable groups. It is necessary to regulate the negative externalities of modern agricultural production, but if the environmental regulation is too strict and the span of policy flip-flop is too large, it is easy to cause the rise of food price and social crisis. How to find a balance between food security and agricultural sustainable development, more broadly speaking, the trade-off between the right to development and the right to survival, is a focus of future agricultural policy.
