Has it ever occurred to mankind that the recent bad weather is ultimately caused by human beings themselves?

In recent years, many disasters have occurred in Taiwan Province Province, some of which are purely man-made events, such as air crashes, fires and car accidents. Others can be called natural disasters, which are caused by natural events, including the collapse of Lincolnshire caused by landslides, the debris flow disaster caused by Typhoon Herb, the foot-and-mouth disease incident, the Keelung River flood, and the worst 92 1 Chi-Chi earthquake in a hundred years. However, it can be found that even natural disasters are invariably mixed with human factors to varying degrees. In other words, many natural disasters also include several human factors, which are actually the result of the interaction between natural forces and human forces. Serious natural disasters not only cause loss of life and property, but also sometimes cause social chaos and even the collapse of the government. During the Chongzhen period of the Ming Dynasty, there was a national drought, plus a plague of locusts. 1556, Shaanxi earthquake, hundreds of thousands of residents were killed, resulting in "hungry people everywhere, hungry people blocking roads." Finally, they gathered into bandits and rebelled, which led to the demise of the Ming Dynasty. Even in modern times, similar situations are often repeated. For example, Bangladesh was hit by a typhoon at 1970, and the death toll was as high as 200,000. 1980 A major earthquake occurred in southern Italy, and the national economy was depressed, which led to the collapse of the government. It can be seen that natural disasters and man-made disasters always intensify each other. Therefore, the ancients said that "man-made disasters induce natural disasters, and natural disasters aggravate man-made disasters." Take the flood as an example. Although the main reason is the imbalance of precipitation in space and time, which is often caused by heavy rainfall and continuous rainstorm, after comprehensive analysis of the reasons, it will be found that the upstream deforestation, destruction of vegetation, soil erosion caused by improper reclamation, reclamation around lakes, encroachment on rivers, and river blockage caused by competing for land with water are also important reasons for the expansion of the disaster. Therefore, the causes of disasters are varied. For each kind of disaster, we should investigate the causes from both natural factors and human factors, so as to provide scientific basis for more effective disaster prevention and mitigation. The result of economic development is that the ecological environment on the earth's surface deteriorates and becomes fragile, which is the direction that human beings must strive to improve. This shows that in the disaster relief work, we should not only strengthen geography, geography and science and technology education, but also arouse public awareness and concern about the environment through environmental education. Second, the relationship between environmental degradation and natural disasters is global, and natural disasters seem to have several obvious trends (see figure 1). The first is the harm of natural disasters. Secondly, the cycle of occurrence is getting shorter and shorter; In addition, the degree of harm is getting more and more serious, and the loss of life and property is gradually increasing. According to the natural disasters reported by Taiwan Province Provincial Newspaper for many years, there is a similar situation (Huang Chaoen, 1998). According to United Nations statistics, from 1970 to 1990, various natural disasters in the world caused more than 2.8 million deaths and 820 million victims. Among them, 54 times were classified as serious natural disasters, and 20010.5 million people died. Among them, there were 20 earthquakes, and the death rate was 1 6,543.8+0.5 million, which shows the threat to human beings. Therefore, the United Nations named the last decade of the 20th century the International Decade for Disaster Reduction (IDNDR), hoping to take concerted global action. Use effective methods to minimize the impact of natural disasters on human beings. Of course, the increasing severity of the above disasters cannot be said to have nothing to do with the essential changes of natural disasters, but from the perspective of natural laws, the performance of natural phenomena is mostly normal. The change of the environment is inherent, but this change is often gradual, rather than being able to detect its sudden change in just a few decades. Therefore, many scholars believe that this kind of disaster is getting worse. It should be related to the way human beings use it and wantonly destroy the environment. Due to the long-term blind development of environmental resources and excessive use and demand for nature, many mutated "natural" disasters have occurred. Some of them are entirely caused by human factors, including all kinds of pollution and global environmental changes (such as global warming and ozone layer depletion). It is a man-made disaster. For disasters aggravated by improper human activities, it is called man-made disasters to increase their scale, amplitude and frequency on the basis of the original foreseeable disasters. Human activities often worsen the environment. On the one hand, the fragility of the environment becomes obvious and the self-regulation ability becomes weak. On the one hand, people's ability to resist disasters is declining day by day. On the other hand, many human processes of destroying the environment are natural disasters. Under the influence of these multiple factors, it is of course expected that natural disasters will emerge one after another and grow rapidly.
