In 2135, the earth today no longer has countries, there is only one earth federation. On Earth, technology and nature have become intertwined, forming a highly complex and interdependent ecosystem. In this new era, people have long been accustomed to living with advanced artificial intelligence, and brain-computer interfaces are essential for people in the future.
However, the explosive development of science and technology has also brought about two very important problems.
The first is the population explosion. Now the earth's population has exceeded 15 billion. Although some land problems can be solved by reclamation, the earth is still very crowded. Now people have to build their houses higher and higher. There are many houses that are one thousand meters and two thousand meters high.
The second is the energy crisis. The energy produced by nuclear fission has gradually been unable to meet the daily needs of people on earth. Controlled nuclear fusion technology has not been completely controlled by humans until now. Therefore, the earth is now divided into two groups. One group of scientists and conservatives believes that there is a need to increase the control of controllable nuclear fusion. The other group believes that instead of wasting money on this problem that cannot be solved for more than a hundred years, returning the earth's population to the level of 100 years ago can fundamentally solve a series of problems caused by the energy crisis and population crisis.
