The population of the world now exceeds 5 billion. According to statistics, the world’s population will increase by 1 billion every 12 years or so. At this rate, by the year 2800, the global population will occupy an average of 40 cm 2 of land. By 4310, the global population will weigh more than the earth. the weight of. From this point of view, in addition to controlling population growth, humankind must also study the way of living in the future. Some urban scholars use advanced science and technology knowledge and rich imagination to conceive many plans for the future of mankind. Here are some examples, some of which are being put into practice.
