Desert weather

Today, let's talk about the influence of dusty weather.

Dust weather will reduce land resources, dust weather will reduce China's limited land resources, and the quality will also decline. In the past half century, the cultivated land and grassland degraded by desertification in China have reached 7.722 million square meters and 6,543.8 billion square meters respectively.

Dust weather will also have a great impact on our people's production and life, because dust weather will carry a lot of dust, and then it will cover the sun, and the weather will be gloomy, resulting in reduced solar radiation and reduced visibility for several hours to more than ten hours, which will make people feel depressed, thus reducing our study efficiency and work efficiency.

From mild infection, a large number of livestock can be infected with respiratory and gastrointestinal diseases, and even a large number of livestock will die.

Moreover, the dusty weather will aggravate the wind erosion and desertification of the surface soil and cover the leaves of plants. Thick dust will also affect normal photosynthesis, leading to crop yield reduction, and dusty weather will also make the temperature drop sharply, just like holding up a parasol in the sky, the ground will become cold and dark because it is in the shadow.

Dust weather will also affect the operation of our transportation facilities and power facilities. Dust weather will seriously affect our traffic safety, resulting in the aircraft can not take off and land normally. Good night, cars and train glasses will also be damaged due to dusty weather, thus causing suspension or derailment.

Dust weather will also seriously endanger our health. When our human body is exposed to dusty weather, there will be all kinds of germs and dust of toxic chemicals entering our respiratory tract, and there will be a lot of dust of harmful substances. If it is not cleaned up in time, it will cause serious damage to our respiratory organs. These germs and harmful substances will invade our organs and cause various diseases.

The floating soil in dusty weather will enter our lungs through our respiratory tract, causing allergic reactions and irritation to the human body. Because the part that comes into contact with these dusts is the lungs, the performance in the lungs will be very serious.
