|     If only using artificial  soil technology and engineering agricultural technique, soil degeneration and  grassland desertification in our country will not happen, green vegetation in  the nature will be restored, the adjusting functions of forests and grasslands  and lakes and rivers and seas and oceans and marshes as well as wetlands on  climate change will be renewed to the original state, harmonious coexistence of  human being with the environment surrounding them will take place.By that time  the climate conditions in the world, especially in China will be greatly  improved.In order to improve the globe climate, the  key is to renew the natural ecological environment, especially the functions of  green vegetation. This is a huge systematic engineering project, it needs 2000  years in China  and 4000 years in the world by about 200 generations to finish. We are clear  about the target now, but it depends on our determination and efforts.
