Earth Systems Science
Earth system science treats the entire Earth as a system in its own right, which evolves as a result of positive and negative feedback between constituent systems.Earth is a dynamic planet; the continents, atmosphere, oceans, ice, and life ever changing, ever interacting in myriad ways. These complex and interconnected processes comprise the Earth system, which forms the basis of the scientific research and space observation that we refer to as Earth system science.
 This definition of earth systems science originally came from Wikipedia in 2007. Unfortunately Wikipedia is open to the public to edit and does attract people who do not know what they are talking about from time to time. The current definition is too long.
