Zhang Wei knows nothing about the current situation of global food. Therefore, he can only make up for the relevant knowledge and know how much more food production is needed each year to protect China from food crisis.
When he gave an order, Xiaolan, the intelligent assistant, displayed the information he wanted to know on the virtual stereoscopic screen.
After careful study for a while, Zhang Wei finally got a preliminary understanding of the current situation of grain in China and other countries.
The world's annual food production is less than 2.5 billion tons, 1.4 billion Chinese consume 700 million tons, 300 million Americans consume 300 million tons, 700 million people in Europe consume 400 million tons, and the other 4.5 billion people consume 1.1 billion tons.
From these data, we can see that there are many people starving in the world, and a report released by the FAO and the world food programme also points out that the global hunger population has reached a record 1 billion, more than half of which are children. According to statistics, 18000 children die of hunger and malnutrition every day, most of them in Africa, which is hard to say In the 21st century, this is a tragedy of imagination.
Of course, this has a lot to do with Africans themselves. They can't support too many children, but they prefer to have children. In the past, many children died because of the backward medical technology. Now with the development of medical technology, the life expectancy in Africa has been greatly extended, which makes Africa facing the population explosion, the 40 countries with the highest fertility rate in the world, 38 of which are in Africa Zhou! According to a new UNICEF study, by 2100, there will be 4.2 billion people in Africa, and almost half of the world's children under the age of 18 will come from Africa, currently only a quarter of them.
Africa is facing a population explosion, and China is about to enter the space age. A large number of scientists are needed. They have decided to fully liberalize the family planning policy. In the future, the population will inevitably continue to increase, and the food consumed will naturally increase, so where do these excessive food come from? Is it totally dependent on imports?
It is important to know that the global grain trade volume is 200-300 million tons per year. Even if all these grains are purchased, they can only meet 40% of China's current grain demand. If China really buys so much food, the price of food will surely skyrocket, and China must pay a huge price. And if we rely on imports completely, it means that we have handed over the lifeblood of our country to other countries, which is quite a dangerous act. As long as other countries pinch our food supply a little, we will be soft immediately. Why? Food is never broken overnight.
Therefore, food should still be self-sufficient. Even if we want to import, we should have the courage to face the worst situation: "even if they don't sell to us, we can still survive by relying on our own food production, at most, we can only eat less meat." In fact, the country has been doing so for many years, and has been insisting on the red line of 1.8 billion mu of arable land.
After knowing the current situation of the food problem, Zhang Wei felt a little startled. At the same time, he felt that the problem really needed to be solved urgently. The whole country is about to enter the space age. In the future, a large number of scientists are needed, so scientists can't go hungry. In the future, if we want to carry out interstellar colonization, we must need a large number of people. These people also need to consume a lot of food. There is not enough food. Everything is empty talk.
So, how to make crops increase production? How to develop more cultivated land?
As for the first question, it is natural to cultivate high-yield crops. In fact, the space plants that science and technology companies are actively studying in the future belong to this kind of research. Genetically modified crops are actually a way, but it will take a long time to verify whether they will cause harm to human beings. The domestic people are also highly resistant.
As for the second problem, there are actually two ways. The first is to cultivate crops that can adapt to the harsh environment, such as rice that can fully adapt to the saline and alkaline land. The total area of saline alkali land in China is about 1.5 billion mu. If rice can be planted, the annual grain yield will be 450 billion jin, which is equivalent to about 37% of the national grain yield in 2013. In fact, China has made some progress in this regard.
The second way is to transform the land that is not suitable for planting crops into the land that is suitable for planting crops.
Experts once had relevant ideas: "sea water is lifted from the northwest coast of Bohai Sea to an altitude of 1200 meters, to the southeast of Inner Mongolia Autonomous Region, and then along the east-west direction of the 42 ° line of north latitude to the surface of the trough, passing through Yanshan and Yinshan to the north, leaving Langshan to the West and entering Juyan sea, bypassing the rest of Mazong mountain and entering Xinjiang. The terrain of Xinjiang is higher in the East and lower in the West. After entering Xinjiang, the sea water can form self flow. Then, the natural river course of Shule River "flowing from the east to the west" is used to flow into Lop Nur, the eastern margin of Tarim Basin
This is the project of "sea water transfer to the west". It is supposed to fill the dry salt lake, salt lake and closed structural basin in the desert with a large amount of sea water to form man-made sea water river and lake, so as to suppress the desert. At the same time, a large number of sea water rely on the abundant solar energy natural evaporation in the northwest to increase rainfall as the water and gas supply source of wet to wet northern climate, so as to achieve the goal of controlling China's deserts and sandstorms and completely changing the poor ecological environment in North and Northwest China.
When this idea was first put forward, it aroused a wide debate and query from the national public opinion, which has not yet subsided. Some people even ridiculed it as a joke like "tiling the Great Wall".
In fact, there were many shortcomings in this assumption at that time. The main reason was that the cost of the project was too high, and the cost of transporting seawater was too high. In addition, there was a large-scale land salinization risk when seawater entered the inland.
However, with the small nuclear fusion furnace technology provided by Zhang Wei, i.e. the success of controlled nuclear fusion, all these problems are not problems.
As we all know, helium-3 is the raw material of nuclear fusion. Every kilogram of helium-3 burned can produce 19 megawatts of energy. 100 tons of nuclear fuel helium-3 can meet the energy demand of the whole year on earth. However, the capacity of chang'e-7 spacecraft that is being manufactured by the state exceeds 500 tons. That is to say, as long as chang'e-7 transports helium-3 to the moon once, it can meet the energy demand of the earth for five years We can also see from these data that as long as nuclear fusion power plants are widely used, the cost of electricity will inevitably be reduced to an appalling level.
With such a low cost of electricity, the cost of desalination will also be greatly reduced. After desalination, fresh water can be introduced into North and Northwest China to control deserts and sandstorms and completely change the harsh ecological environment in North and Northwest China. The whole construction work of the project can be completely constructed by intelligent robots, which do not need wages, only need cheap power and energy, and can work 24 hours without complaint, with strong working ability, which can greatly reduce the cost of the project. As for the cost of transporting water, according to the calculation, raising a ton of water to 1280 meters above sea level requires 6.4 degrees of power consumption. This cost is a little high in the past, but it is not worth mentioning now.
Therefore, the project of "sea water transfer to the west" can be fully implemented now.
Not only that, the project can be expanded. There are eight deserts from east to West in the north of China. They are Horqin, Hunshandak, Maowusu, Kubuqi, Ulan Buhe, Tengger, Badain Jilin and Taklimakan deserts. In the past, we didn't have a big way to take these deserts, but now we can completely break the traditional mindset and make full use of the vast water of Bohai Sea to transform all these deserts into cultivated land or residential areas, which is equivalent to adding several provinces of land to the country. With such a large amount of land, the country's population will be more than one billion, and its food will be fully self-sufficient, which is totally beneficial to thousands of people The feat of autumn.
In addition, China can build a large number of desalination plants to provide cheap fresh water and completely solve the problem of water shortage faced by major cities in China.
It has to be said that with the technology of small nuclear fusion atomic furnace provided by Zhang Wei, many ideas that seemed to be difficult to realize in the near future, or that seemed to be wishful thinking by many people, can be implemented now. This is the power of technology, and this is the change brought about by Zhang Wei.
Zhang Wei said he was calm about this. Compared with the star transformation he was going to carry out in the future, these projects are just small cases. (to be continued. )
