(Dust Travel)
Dust is a traveler, it is very small, it floats with the turbulence of the air, walking around the world with the wind.
The air around us, from indoor to outdoors, from the city to the countryside, from flat land to high mountains, from desert to ocean, almost everywhere. There is really no dusty space, only in the laboratory can it be made.
Dust is the destructive of the breathing. They can cause the nostrils, inflammation of the trachea, and the lungs of the lungs. If the tuberculosis is mixed in the dust, it is even more dangerous. Therefore, spitting must be prohibited everywhere. In addition, the dust of the metal, especially the lead, will make people poisoning; the dust of lime and cement will damage our lungs and corrode our skin; the dust of pollen will cause asthma. In these cases, in order to resist the offensive of dust, we must put on a mask or mask. In the end, dust does not cause explosion. This is a serious accident and must be prevented. Therefore, we should pay more attention to washing hands and bathing, and pay attention to environmental hygiene and personal hygiene. Let us have a better body and a better home
