Science and technology are not there for fighting against the nature. Some people are thinking that they can use the technology as a weapon to fight with the nature. First of all we must have the ability to manage the property of natural environment. There are lots of things which are in the natural environment for the persistence of human beings. Sun light, natural water cycle, earth, soil and plants are there for better life and long time existence of both human beings and animals. The reality is there must be a technology for managing these resources. Science is not only physical science and its related things. If we can manage these things which are in the surface of the earth well, no need to excavate it hard.
