Composition on disaster prevention and reduction

Natural disasters, including man-made disasters, are people's biggest enemies. There are many natural disasters, such as earthquakes, acid rain, greenhouse effect, typhoons, etc. Man-made disasters include fires, soil erosion, etc. As far back as ancient times, people had no awareness of prevention and prayed to gods and Buddhas for protection and safety. With the development of society, people know how to use scientific principles and practical methods to protect themselves and reduce disasters that threaten their lives. This article will tell you how to use scientific methods to prevent earthquakes and reduce disasters, protect yourself and your home.

According to surveys, major earthquakes occurred in many places across the country, such as the 1514 Dali earthquake in Yunnan, the 1975 Haicheng earthquake in Liaoning, the 1605 Qiongzhou earthquake in Hainan, the 1786 Nandi earthquake in Kangding, Sichuan, and the 1976 The Tangshan Earthquake in 2008... so many disasters, causing heavy damage, especially the Tangshan Earthquake, which killed more than 200,000 people and injured them.

In fact, some disasters can be prevented. There are some warning signs before an earthquake occurs. For example, horses and other livestock will break free from the reins and run out crazily; hibernating snakes will rush out of their holes; bees will fly away and flee; dogs will bark, and some domestic animals will break out of the pen and run around; rats will swarm. Moving in groups... These signs can let people know in advance that an earthquake will occur. If these animals are found to have these abnormal phenomena, they must first identify the true and false, and then report to the earthquake bureau so that they can evacuate as soon as possible.

It is not certain that you will die if an earthquake occurs. In fact, there are many ways to save yourself. For example: There is an earthquake and you are trapped under the rubble. At this time, don't move blindly. Be calm. Take your hands out first and slowly move the rubble. Keep your breathing smooth first, and then find a way to breathe and call for rescue. you. If you are at home when an earthquake occurs, you must immediately get into a small room that is hard and has not collapsed to avoid being injured. Also, you should stick to a solid wall or squat at the door to survive after the house collapses to avoid being injured. If you are in the wild, be sure to avoid steep cliffs to prevent falling down the mountain. There is also the need to prevent landslides to avoid sliding down. If you are in school, you must follow the teacher's instructions, hide under the desk, and protect your head. If you are in physical education class, avoid tall buildings to avoid being injured. If you are in a movie theater, hide under the viewing chair to avoid shock, avoid lights hanging on the ceiling and air conditioners, use something to protect your head, and follow the command of the commander to evacuate the scene. If an earthquake occurs in a shopping mall, avoid glass cabinets, goods, billboards, lights and other items. If you are in a bus, hide under a chair or squat down, stabilize your center of gravity, and hold on to the armrests.

Other natural disasters are not as inevitable as earthquakes and are sometimes completely controllable.

Acid rain is called the "god of death in the air" because the exhaust gases (sulfides) emitted by people's factories float into the air. When it rains, they fall with the rain and become acid rain. Acid rain will cause lake water to become acidic and fish and shrimps to die; forests will gradually age; farmland will become barren; once it drips onto cultural relics, precious calligraphy and paintings, they will be corroded immediately... It can be seen how harmful acid rain is to people!

The greenhouse effect refers to an effect in which gases in the atmosphere absorb infrared rays, causing temperatures to rise. It is also very harmful and can cause many people to lose their lives, especially the elderly and children. The greenhouse effect can cause people to suffer from lung diseases such as asthma, and can also cause many diseases, such as encephalitis and high fever. It will also cause droughts, floods, food shortages, and severe property losses in many places.

There are also many natural disasters, many of which are "masterpieces" of human beings themselves. Therefore, we must have this knowledge and not harm ourselves.

Not only natural disasters, but also man-made disasters. Such as fires, mudslides, water and soil erosion, etc., are all unnecessary losses caused by human beings cutting down trees.

So, I suggest that everyone do the following:

1. Protect forests, plant trees, and protect water and soil.

2. Factories should not emit too much waste gas and use inexhaustible solar energy.

3. To protect the ozone layer, cars should not emit exhaust gas.

4. Be careful with fire and don’t throw away cigarette butts.

5. Learn more about earthquake and disaster prevention and be aware of prevention.

6. Save water and cherish every drop of water.

If these points are done first, the occurrence of disasters will be reduced, or many lives will be saved once a disaster occurs.

To protect our home, the earth, is to protect yourself. Let us take action to jointly prevent disasters and make the earth brighter and more brilliant tomorrow!
