Please tell me a specific example of serious damage to the environment in order to develop the economy

There are many such examples, which are common phenomena. I pointed out some small conditions, which should not be difficult. For example, in order to develop the economy, a certain area belongs to the category of resources, so the general trend is to develop resources, but it is to eliminate backward technologies. Now the local economy has developed, but the destruction of the environment has restricted the development of the local economy. There are mainly the following points: first, the original damaged ecological environment can not be restored, such as vegetation; Second, the investment in governance is high, the local economy is under great pressure, and the investment in drinking water projects for people's livelihood projects is quite large; Third, the total amount of local pollutants discharged is already very large, and there is no remaining discharge space at all, so new projects cannot be approved.

You know the Sanmenxia water control project, which can be said to be a major failure of China water control project. So far, it is not allowed to discuss it openly and effectively in China. But the accounts always have to be counted. Let's first look at the direct economic losses:

(1) The high dam project runs at low dam, which means that a lot of manpower, material resources and financial resources are wasted only by the project itself;

(3) Two updates, including the cost of repairing worn holes and turbines;

③ More cultivated land is flooded and destroyed;

④ More than 300,000 people were relocated at that time, and 6.5438+0.5 million people moved back later;

⑤ Since the operation of the reservoir, due to the change of the natural conditions of the river, the reservoir area includes the regulation of the lower reaches of the Weihe River, flood control facilities on both sides of the river, saline-alkali land treatment, and protection works that must be built for bank collapse and landslide;

Yield reduction due to salinization of fertile land caused by rising water level; During the period of "water storage and sand retention", the fertile land in the downstream production levee was washed away by the release of clear water; These, the most conservative estimates, are not less than10 billion.

Look at the damage to the environment:

① The groundwater level around the reservoir rises, and more than 500,000 mu of cultivated land is salinized;

Reservoir impoundment leads to bank collapse and farmland loss;

Destroy precious cultural relics in the birthplace of culture; Needless to say, there is a mistake in time: if these manpower, material resources and financial resources are invested in dike reinforcement and other effective water conservancy facilities in the lower reaches of the Yellow River; Investment in transportation and communication systems; Investment in educational and cultural facilities; Even if we only invested in water saving, afforestation, protection and irrigation in the upper, middle and lower reaches of the Yellow River, the situation in the whole basin would not be like this today.
