Earthquake prevention and disaster reduction, natural disasters, beautiful homeland, awareness of prevention, man-made disasters, according to the survey, there are many major earthquakes in many places in China, such as Dali earthquake in Yunnan/KOOC-0/5/KOOC-0/4, Haicheng earthquake in Liaoning/KOOC-0/975, Qiongzhou earthquake in Hainan/KOOC-0/605, and Qiongzhou earthquake in Hainan/KOOC.
In fact, some disasters can be prevented. Before the earthquake, there will be some signs. For example, domestic animals such as horses will break free from the reins and run wildly outside; Hibernating snakes will come out of their holes; Bees will fly around; Dogs will bark, and some livestock will run around in circles; Rats move in groups ... these omens can let people know in advance that there will be an earthquake. If these animals are found to have these abnormal phenomena, we must first distinguish between the true and false, and then report to the Seismological Bureau to prevent them from leaving early. An earthquake doesn't mean you will die. In fact, there are many ways to save yourself. For example, you were trapped under the rubble in the earthquake. At this time, you should not act blindly, but be calm. First, take out your hand and move the ruins slowly. First keep breathing smoothly, then try to breathe and call for help. If you are at home during the earthquake, you must immediately enter a hard small room that has not collapsed to avoid injury. Also, stick it on a solid wall or squat at the door, and survive after the house collapses to avoid being hurt. If you are in the wild, you must avoid steep cliffs to prevent yourself from falling down the mountain. There is also the need to prevent landslides, so as not to slide down. If you are at school, you must obey the teacher's instructions, hide under the desk and pay attention to protecting your head. If you go to physical education class, avoid tall buildings and don't get hurt. If you are in the cinema, you should hide under the viewing chair to avoid the shock, avoid the lights hanging on the ceiling and the hanging objects of air conditioners, protect your head with things, and follow the instructions of the commander to evacuate the scene. There was an earthquake in the shopping center. Avoid glass cabinets, commodities, billboards, lights and other items. If you are on the bus, you should hide under the chair or squat down, keep your center of gravity stable and grab the handrail. Other natural disasters are not as inevitable as earthquakes, and sometimes they can be completely controlled. Acid rain is called "death in the air" because the waste gas (sulfide) emitted by people's factories floats into the air. When it rains, it turns into acid rain with the rain. Acid rain will cause the lake to turn sour and kill fish and shrimp; The forest is getting old; Farmland becomes barren; Once dripping on cultural relics and precious calligraphy and painting, it will be corroded immediately ... It can be seen how harmful acid rain is to people! Greenhouse effect refers to an effect that gases in the atmosphere absorb infrared rays, which leads to an increase in temperature. Its harm is not small, it will make many people lose their lives, especially the elderly and children. The greenhouse effect will make people suffer from lung diseases such as asthma, and it will also cause many diseases, such as encephalitis and high fever. It will also cause droughts, floods, reduced grain production and serious property losses in many places.
There are also many natural disasters, many of which are human's own "masterpieces". So have this knowledge and don't hurt yourself. Not only natural disasters, but also man-made disasters. Such as fire, debris flow, soil erosion, etc. It is human beings who cut down trees themselves and cause unnecessary losses. Therefore, I suggest you do the following:
1. Protect forests, plant trees and protect water and soil.
This factory should not emit too much exhaust gas, but should use inexhaustible solar energy.
In order to protect the ozone layer, cars should not emit exhaust gas.
4, be careful with fire, don't throw cigarette butts.
5. Learn more about earthquake prevention and disaster prevention, and have awareness of prevention.
6. Save water and cherish every drop of water.
If these points are done well first, the occurrence of disasters will be reduced, or many people's lives will be saved once disasters occur.
Protecting our home, the earth, is to protect ourselves. Let's take action to prevent disasters and make the earth's tomorrow brighter and brighter!
