What would happen if all the deserts were turned into farmland? Can you talk about it?

Desert covers13 of the earth's land and has the driest ecosystem, with annual rainfall less than 25cm. With the increasing population of the world and the decreasing cultivated land, can we turn a dead desert into a granary thousands of miles away? What impact will it have on the global environment? It is very difficult to grow anything in the desert. Evaporation and transpiration make them extremely short of water, and even some deserts may lose 33 times as much water as they absorb.

If you want to turn the desert into farmland, you need to help the land keep more water. One way is to mix special clay in the soil and cover it in the desert. This nano-scale clay has extremely tiny clay particles, which are 500 times smaller than the diameter of a hair. There is such a mixture of clay and gravel on the desert surface, so that water and nutrients will not be easily lost. In Arabia, through experiments, planting watermelon in a deserted desert within 40 days can reduce water loss by 47%. Tiny clay particles can bind water and nutrients together. Some people even think of mixing these tiny clay particles with water to make liquid nano-clay, and spraying it directly into the desert through irrigation systems such as sprinklers and water guns without spending too much manpower. If successful, the desert will retain more water and form a new world granary in ten years.

Many countries in the world are transforming deserts in a planned way, but what would happen to the earth without deserts? Amazon is the lung of the earth. It absorbs carbon dioxide, helps the earth resist climate change and releases a lot of oxygen to improve air quality. But why does the disappearance of the desert affect the Amazon rainforest? The sand in the Sahara desert, the largest desert on earth, will cross the Atlantic Ocean to reach South America. In this process, fine sand will absorb moisture in the air and then form raindrops over the Amazon rainforest. Their arrival will make the rainforest have more soil and water and make the land here more fertile. But if the desert turns into fertile land, this cycle pattern may be destroyed, the Amazon rainforest will shrink rapidly until it disappears, and the natural balance of the earth will be destroyed. A large number of rare animals and plants living in the Amazon rainforest will be extinct, which is also a disaster for human beings, and there are similar situations in other deserts. The ecosystem of the whole earth is very fragile. If you improve this place, it may have an impact on another place. But some man-made deserts can still be planted.
