About ten thousand years ago it was the end of Old Stone Age which had 5.32 million of population, but at thebeginning of Old Stone Age it was 125 thousand of people. By comparison the population had increased by 42 times. In New Stone Age people made stone implement using grinding method and their food did not depend on collecting and hunting but the food was from planting the crops and raising the animals mainly. At that time human beings had made a huge leap from collecting food to producing food. This is called the Agricultural Revolution in human history.
Historical experience is worth recollecting. World five inventions have all had an arduous process from its appearance to forming an industry. It cost several million years from walking upright to forging stone implement by human ancestors. Also it cost several million years from forging stone implement to grinding stone implement. I believe that Peking Man had grasped the technique of making fire at their middle and late period of life, but from that time to using fire widely also cost several hundred thousands of years. I speculate that our ancestry understood the principle to get food by planting the plants and raising the animals long time ago, but agriculture and animal husbandry appeared several ten thousand years later. Early Egyptians, when Greek governed it in about the third or fourth centuries B.C., had used steam as power to open and close the door of the temple. However it was more than 2000 years later during the industrial revolution when steam was used widely in industry and transportation and agriculture and military etc. By this inference I don’t know when my artificial soil technology will be industrialized. Perhaps God can answer me.
But I believe that the World will accept my artificial soil technology and it won’t be long. Because the world population is increasing rapidly and the world population exceeds 6 billion and then 10 billion, 15 billion, 20 billion in no time. Don’t solve the problem of land resources, human beings have no way out, especially China. So I say that human beings are in the eve of the agricultural revolution.
