As we all know, 70%of the surface of the earth we survive is the ocean, and the land area accounts for only 30%. Among this 30%, there is still a lot of bad terrain such as deserts that is difficult to develop and utilize.
At present, the desert area of the world has reached an amazing 30 million square kilometers, accounting for 20%of the land area of the earth. And with the influence of human activities, the desert area is still expanding year by year.
There are two main reasons for the formation of the desert, one is natural reasons, and the other is human reasons.
Natural factors are mainly due to the impact of climate and terrain. Under the influence of these factors, desert drought is short of water. It is not difficult to find that the desert formed by natural reasons is often caused by multiple natural factors.
Human factors are mainly reflected in unreasonable human behavior, including excessive grazing, excessive tree cutting, and so on. Our earth's ecology itself is relatively fragile if human malicious damage will from a desert.
There were many grasslands worldwide, and after being destroyed, they became a desert.
The desert has a greater impact on the surrounding environment, and the most typical is that it is easy to cause sandstorms.
We know that there is no vegetation growing on the surface of the desert, so the soil on the surface is easily blown by the wind to form sandstorms.
The temperature of the desert area is small so the temperature will rise under the sun during the day, which will exacerbate the water in the soil.
Too high a temperature can also cause water vapor to float at high altitudes, and it will not land on the surface of the desert so the local evaporation is far greater than the rainfall.
The disappearance of the desert has many benefits for us. First of all, there are almost no creatures that can survive in the desert. This is because the cells of all creatures are made of water so all creatures cannot survive in extreme water deficiencies.
Therefore, the disappearance of the desert will not cause any creature to die or extinction.
Conversely, the disappearance of the desert will expand the habitat of biology.
Taking birds as an example, many birds do not just survive in one place but migrate with the changes in the seasons. In the process of migration, birds will stop, looking for middle stations as supplies, where they will find food and rest.
The disappearance of the desert means that they can use it as a supply station, replenishing energy through the grass seeds or insects, small animals, or plants.
They can also replenish water sources through lakes, and even some birds can reproduce offspring here.
At the same time, governing the desert can also improve air quality. Turning the desert into an oasis can reduce the greenhouse effect. More importantly, there are no sandstorms.
In the desert area, the influence of sandstorms is very serious. Once we are involved in the storm, the consequences will be unimaginable.
Governing desert is related to the human homeland. Take the world's largest desert, the Sahara desert area is 9.06 million square kilometers, which is the second largest desert except for Antarctica.
If we can control these 906 million square kilometers of desert, even if the population of the earth will increase to 8 billion in the future, we can be fearless.
