It is a fact that natural disasters are expanding year by year, but it is false that grain production is increasing year by year. The sharp increase of GDP every year will inevitably lead to the increase of destructive power to nature, which will naturally lead to the trend of expanding disasters every year. For local governments, the reason for falsely reporting the increase in grain production is the need of political achievements, and for the central government, it is the need to emphasize the correctness of the existing line, principles and policies. Of course, there is no shortage of food in the market now, but many foods have been imported, including genetically modified foods. If one day other countries don't export food to us, or war or genetic modification threaten us to eat, will we have enough food? This is the crux of the problem.
