The earth has entered a period of hydrological, climatological and biological changes that differs from previous episodes of global change. Environmental science has been divided among the study of the atmosphere, the hydrosphere, the geosphere, and the biosphere. To an increasing extent during their brief time on earth, humans have used their ingenuity and technology to cause enormous perturbations in the natural environment. This has occurred to such a degree that it is now necessary to recognize a fifth sphere of the environment that is constructed and operated by humans, the anthroposphere. To explain or predict the cause of the present global environmental changes, one must therefore understand the human sources, consequences, and responses. To understand global environmental change it is necessary to focus on the interactions of environmental system , including the atmosphere ,the biosphere, the geosphere and the hydrosphere as well as human system, including economic, political cultural and socio technical system. Human system and environmental system meet in two places: where human actions proximately cause climate changes, i.e. where human activities directly affect the environment, and where environmental changes directly affect the human life.
