Up to the present, geology has served to the human life through the development of the subterranean resources, -metal, non-metal, coal, oil and natural gas. But it was committed to the care of the circumstances of the entrepreneurs for mines or factories. In a word, our daily life can not be directly a recipient of favours of their developments. The extension of engineering geology has done keep down of full breadth these intermediary factors. For instance, if an engineering geologist failed to specify geologically the dangerous point on the construction spot, people may be securely faced to suffer the dangerous attacks. We shall have essentially the social instinct to protect ourselves and to keep our daily life at a distance from the natural disasters. Our human society demands geo-scientific explorations or fundamental researches for promoting the conservation of the land and landwaters or the prevention of the land disasters. Accordingly, our applied geology in future will be predestined to approach to the entrance of environmental sciences. I think, applied geology should be a catalyzer to promote such activities.
