If a food crisis breaks out, these unexpected things can still fill your stomach.

The food crisis has not happened in history. Throughout the history of human civilization, we have been fighting against food all the time, and eliminating hunger has always been a perplexing issue for mankind. Even now, when we feel that we have no worries about food and clothing, there are still many African brothers and sisters struggling at the poverty line to find a way out to feed their stomachs.

So historically, what kind of food do human beings have to eat at a time of food crisis? Next, let's go back to history, learn from the past, and take an inventory of what we ate in famines in the past with the idea of vigilance.

There is a clear description of Henan famine in Liu Zhenyun's novel 1942, but in the film changed by director Feng Xiaogang, we can see the scene of famine at that time, the film may be artistic, or the real history is far more cruel than the film.

The "disaster Bulletin" published by the National Government during the period of the Republic of China has a more detailed record of the food eaten by the flood victims in Henan Province at that time, which details the types of food, eating methods, post-eating phenomena and so on (above).

For the poor who are struggling to die of hunger, some people even precipitate the loess in a water tank, and then take out the fine sand from the temple to make mud cakes to eat. It has been recorded that Lushan victims grind the stones into powder and then take them.

These foods are less like food than the substances in the table above. If there is a real famine, I am afraid people will have a deeper understanding of hunger.

The above is the history part, and let's take a look at the edible substances of the future.

If there is a food crisis, it is believed that there will be a better way of processing food in the future. at present, China is also promoting the staple grain of potatoes. On the one hand, the yield of potatoes is relatively high, and the starch and sugars in potatoes are similar to those of wheat and rice. It is feasible to replace grain to increase food supply. It is also a major strategy to solve the problem of human food and clothing in the future.

Based on the development of today's agricultural science and technology, the future famine will not be allowed to happen again. In recent years, with the extensive promotion of genetically modified technology internationally, the progress of grain production is obvious to all. However, today, we still increase global food reserves, avoid food shortages caused by natural disasters, and be vigilant in order to enjoy peace.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
