To what extent should human science and technology develop to change the weather?
No matter how our science and technology develop and how our economy develops, the most fundamental industry is agriculture. That is to say, we must first ensure our food security, and then we can put on warm clothes and consider a more enjoyable life. Without agriculture, all industries are castles in the air, because when you don't even have enough to eat, you don't remember what entertainment is, so the biggest impact of natural weather is to affect agriculture. If it doesn't rain when it should rain, then the development of agriculture will naturally be affected, such as grain production reduction or even no harvest. If human beings can control the weather, the development of agriculture will naturally be much smoother.
It is estimated that by that time, when our civilization level has evolved to the first level, that is, when we can use all the energy on the earth, all the energy on the earth contains both good energy and bad energy, and sexual means should be fully realized at that time, because at that time we may have been able to use the huge energy generated by earthquakes and volcanic eruptions. It can make full use of all the resources on the earth without causing long-term harm to the environment. The utilization of that kind of resource is beyond our imagination now. It took more than 5 million years for human beings to evolve to a civilization of 0.75, which is the human definition of civilization.
The continuous development of science and technology can really change the weather. Now artificial rainfall can be realized by small-scale dry ice, but there must be water vapor in the cloud, and the amount of water vapor is large enough to be effective. It may take hundreds of years or even longer to control the whole weather system.
