Environmental science is the study of the interactions between humans, other living organisms, and the environment. It focuses on the question of how humans can live, develop and use the earth's resources in way that will not diminish future generations' ability to do the same. Traditional scientific disciplines focus on particular subsets of the natural world. For example, biology concentrates on living organisms, while physics concentrations on interactions among matter and energy.
Environmental science is very different.
Then, we draw upon many disciplines to search for solutions to those problems. Today's environmental problems are increasingly complex. Their solutions require an understanding of multi-faceted scientific issues. The environmental scientist must be able to interact with specialists in these very diverse fields, to understand their language, and to work effectively with them. Environmental science opens the door to many different careers.
