How serious is land reclamation in Japan? Netizen: awesome.

Environmental governance and protection are issues of great concern all over the world, and land reclamation is often criticized by people because it has greatly damaged the local marine environment, and the cost of land reclamation is also very high, so it is generally unnecessary or very necessary.

Friends who travel to Japan should find that many famous big cities in Japan, such as Tokyo, Osaka, and famous ancient capitals, are all near the sea, but there are almost no beautiful seaside beaches, and they are not very beautiful. The offshore part is full of ports and factories built by reclamation. In fact, this is very common in Japan. Looking at the map, it is not difficult to find out how serious the land reclamation along the coast of Japan is.

As we all know, Japan is a mountainous island country, with mountains and hills accounting for more than 70% of the total land area, short rivers and low water flow. Therefore, alluvial plains are often narrow and scattered, and the largest Kanto Plain is only 6.5438+0.6 million square kilometers. Japan has a large population, close to 65.438+300 million people. What shall we do? Reclaim land from the sea.

It can be seen that large and medium-sized cities in Japan are basically port cities, especially in several metropolitan areas. The coastal areas of cities are all reclaimed from the sea on a large scale, and ports and chemical bases have been established. More than 90% of the coastline of the most famous Tokyo Bay is reclaimed from the sea. Tokyo Haneda Airport, Nagoya Central International Airport and Osaka Kansai International Airport are all reclaimed land.

According to statistics, from 1945 to 1974, the total area of land reclamation in Japan was close to1200 million square meters, equivalent to the whole area of China and Hongkong, which was quite crazy. Although Japan has not stopped the pace of land reclamation at present, its scale and intensity have been much smaller. After all, at that time, when the whole society paid little attention to environmental protection, such a large-scale land reclamation did not arouse strong opposition from the society. Nowadays, unlike in the past, it is not easy to continue the crazy reclamation. Moreover, with the development of technology, the grain output has increased rapidly, and there are some surplus industrial products, so it is not so urgent to reclaim land from the sea.

More interestingly, Balangxie, once the second largest lake in Japan, disappeared because of the fiery reclamation project at that time, which became a lingering pain for the Japanese.

Barangxie is a saltwater lake with an area of more than 220 square kilometers, which is connected to the Sea of Japan in the south. In order to increase the rice planting area, Chiba Prefecture began to fill the sea with cofferdams at 1957, but the Dutch method was adopted. First, the internal lake was drained, and then it was filled with soil and transformed into farmland. Although the amount of work is much smaller, it also caused the farmland to be below sea level, and the 1983 earthquake in the Sea of Japan triggered a tsunami.

But sadly, shortly after the completion of the project, agricultural technology improved, and Japan's rice production began to be surplus. At that time, land reclamation seems meaningless now, and Japan has disappeared from the second largest lake. This price can be regarded as a punishment.
