Demoted to the Moon to Raise Pigs

In 2060, the earth experienced the greatest disaster in history: volcanic eruptions, floods and droughts, tsunamis, super earthquakes... The earth was devastated after experiencing the "baptism" of disasters, but it only took 50 years for the earth to repair itself. During this period, with minimal human intervention, after 2110, the earth was like a child recovering from a long illness, showing its unprecedented vitality. All things were restored and species gradually became richer. The people who survived the catastrophe realized that this was the real earth. In the disaster, some countries ceased to exist, and the number of existing countries was less than 50. Scientists from various countries came together to formulate a convention, and the most remarkable convention was to control the population of each country. After the human disaster, various countries achieved unprecedented cooperation and established an Earth Population Control Center. Many countries participated to jointly control the population and, of course, also played a role in mutual supervision. According to scientists' estimates, if the earth wants to prosper in the long term, the population must be controlled within 500 million. According to statistics after the catastrophe, there were less than 40 million survivors. However, after the earth repaired itself, the human fertility rate increased exponentially. In order to control the population and prevent the earth from repeating the same mistakes, the Earth Population Control Center strictly enforces laws and urges countries to control the population.
