The harm of natural disasters

The hazards of natural disasters are as follows:

1. The drinking water supply system was damaged.

Most natural disasters may cause the destruction of drinking water supply system, which will be the first problem after the disaster, and often lead to the outbreak and epidemic of large-scale intestinal infectious diseases in the early stage after the disaster.

2. Food shortage

Although transporting food to the disaster area has become the first task of disaster relief, it is still difficult to completely avoid local food when a large-scale natural disaster involving a wide area occurs. Coupled with the destruction of basic living conditions, people are forced to store food under harsh conditions, which can easily lead to food mildew and corruption, food poisoning and the prevalence of food-borne intestinal infectious diseases.

3. Fuel shortage

In large-scale natural disasters, fuel shortage is also a common phenomenon, especially among victims trapped by floods.

4. Water pollution

Floods often pollute water bodies and cause large-scale epidemics of some water-borne infectious diseases, such as schistosomiasis and leptospirosis.

5. Living conditions have been destroyed.

Floods, earthquakes, volcanic eruptions and tsunamis will all cause large-scale damage to living conditions. At first, people are forced to sleep outdoors, and then they may live in simple shacks for a long time, resulting in concentrated population and crowded living.

Introduction of natural disaster types

1, drought

The total amount of fresh water is small, which is not enough to meet people's survival and economic development. It is generally a long-term phenomenon. Drought has always been the main natural disaster facing mankind. Even in today's advanced science and technology, its disastrous consequences still abound.

2. Blizzard

Natural weather phenomenon refers to a snowfall process in natural weather. Blizzard usually occurs from June 10 to April of the following year. In the middle and lower reaches of the Yellow River and its vicinity, the largest snowfall in the whole year is often in the "rainy" solar term in spring. The appearance of blizzard is often accompanied by strong winds, cooling and other weather, which has an impact on winter traffic and agricultural production.
