Resource is a historical category.The exploitation and using to resource are continuously developed from surface to depth.Because of the difference of human civilization

the dominant resource is also different.Currently

the seven seas badly run short of resource.For the sake of coping with industrial resource-crisis

human beings must carve out a new kind of resource

which is much deeper than the natural mineral resource.In the course of modernization

we must actively advance the deepening of resource

and try to construct deep-resource society.
