Environmental Science and Technology

Environmental science is a multidisciplinary academic field that combines physical, biological and information sciences to the environmental study. The social science fields that are incorporated into environmental science include geography, economics, and political science. Philosophy and ethics are the two fields within the humanities that are also included in environmental science. The surface environment of the Earth is disciplined by interactions between the deep Earth, the atmosphere, the hydrosphere, and the biosphere. This intercommunication occurs on timescales ranging from picoseconds for chemical reactions on mineral surfaces to the millions of years over which plate tectonic processes and earth’s evolution take place. Investigations are open on what shapes our world and the environment in which we live, in order to understand the interactions between Earth's geology, atmosphere, biosphere, oceans, and human responses and roles.
