| 内容記述 | The problem of environmental pollution is rampant around the globe with the passage of time. Here, we take up water pollution seen at Lake Biwa located in Shiga Prefecture in Japan. A few decades has passed since the water pollution of the lake became a topic. Many people who live in Kyoto and Osaka areas highly depend on their water in the lake. If we take contaminated water and fish periodically, our heath will be destroyed gradually. The serious problem is that some materials which cause cancer are included. Thus, we must show some prescription to provide for the safe water and maintain the fishing volume in the lake. Basically, this analysis is based on the models of liner first order differential equations made up by the author. At first, we show the mechanism how this kind of pollution occurs. Generally speaking, many causes are considered including contaminated materials discharged by houses and factories, etc. adjacent to the lake. Time series analysis is taken into consideration to indicate the pollution mechanism. Secondly, we show the decline of fishing volume in the lake. Intuitively, we can imagine the negative correlation between water pollution and fishing volume. Namely, if the water pollution be serious, the fishing volume would decline. Furthermore, we refer to the metamorphosis of ecosystem in the lake. Thirdly, we show the status quo of the lake and how administrative sides tackle this problem. Fortunately, the water pollution of the lake is diminishing and fishing volume is increasing due to the efforts of the parties concerned. However, it seems there needs more improvement to reach the satisfactory level. Finally, we show a future perspective to resolve this problem smoothly by indicating the concrete examples. | |||||
