Why did the famous water conservancy expert Huang Wanli say that "if the Three Gorges Dam is built, it will eventually be destroyed"?

I think what water conservancy expert Huang Wanli said is right. From the perspective of natural protection, ecological environment and humanistic environment, he believes that the construction of the Three Gorges Dam will destroy the nearby natural environment, thus causing The surrounding ecology will be destroyed, and many surrounding cultural landscapes will be submerged underwater. Of course, there may also be various problems caused by immigration. However, everything has advantages and disadvantages. It is difficult to have both. When we encounter problems, we We will make a comparison and make a choice based on the interests. If one day, the negative effects of the Three Gorges outweigh the positive effects, I believe the government will make correct judgments and decisions. We do not need to worry about it, and any one Each kind of building has its lifespan, that is, the number of years of operation. When the service life is reached, the next step still needs to be demonstrated again. We all know that the main function of the Three Gorges is to generate electricity, and then to prevent floods. Now it seems that in the South-to-North Water Diversion Project Can aspects also play a role?

The construction of the Three Gorges Dam is mainly used to generate electricity to alleviate the contradiction caused by the rapid development of the domestic economy and electricity consumption. Compared with thermal power generation, hydropower is a clean energy source with less pollution, although it will have a negative impact on the Three Gorges If the surrounding areas are polluted, the pollution in other places will be much less. Just imagine what will happen if thermal power generation is built across the country. Sometimes when we think about a problem, we just slap it on the forehead, which is one-sided and cannot see the whole picture. , and cannot consider it for a long time.

The positive effects of the Three Gorges are very obvious. In addition to generating electricity, it can also play a certain role in flood control. If it can play a role in the South-to-North Water Diversion process, it will be a great contribution, but I don’t know what the result will be.

Of course, the Three Gorges will also bring some negative effects, although it cannot be proven yet, such as the earthquake in Sichuan, the rain in Chongqing, and the occasional drought in the lower reaches. It remains to be proven whether these are related to the Three Gorges Dam. It needs to be supported by data and cannot be imagined out of thin air. Expert Huang Wanli is said to have conducted experiments back then and concluded that the Three Gorges Dam cannot be built. Considering the technical means at the time and the current specific situation, if it were to be done again It is difficult to say that the conclusions drawn from experiments are unchanged, because the environment is changing, the technical methods are changing, and the other is the lesser of two evils. In order to solve the problem, you have to make a choice. After all, simulation is a simulation, and it is not the same as actual operation. It's not exactly the same, so we still need to adjust and re-evaluate in the process. I believe these tasks will be continuously improved.

Not only the Three Gorges, but any kind of building has its service life. When the service life is reached, what will be the result, whether to continue maintenance or demolition, all need to be scientifically identified, rather than assumptions and guesses. . Perhaps by then, both the water problem and the electricity problem can be completely solved. For example, with the widespread use of nuclear power, there is no longer the possibility of power shortage, and the use of seawater has reached a time when there are no problems. The Three Gorges What is left is only the tourist landscape effect, all of which will have to wait for time to be verified. No one can tell clearly now, even experts, what do you think?
