In order to solve the important problems relating to the existence and development of human beings we need to do the following works. Firstly, beginning from China in 20years when China has enough financial capital, China will begin to carry out a super huge project. First step ：in 20 years the problem of shortage of water resource and the problem of environmental protection will be solved primarily. Second step ：in 200 years the problem of Chinese agriculture especially self-sufficiency in grain will be solved completely. Third step ：In 2000 years Chinese green vegetation will be regained completely and the climate condition in China will be improved. At that moment the Chinese project will be finished.
In another 2000 years all of the projects in the world will be finished（suppose at that moment country will still exist）including African Savanna, Sahara desert, Australian desert, American Rockies, American western area, Arab peninsula and Indian- Pakistan desert etc. So I say that the World need to spend about 4000 years in renovating ecological environment and improving climate condition to the situation similar to that before New Stone Age. It will continue until 6000 A.D. which will take about 200 generations of people to work at the project. These are our tasks and to achieve our goal will depend on our determination and fortitude. Artificial Soil Technology will exist for 10000 years in the world.
