text: Natural Resources Engineering, the sixth Abet accredited environmental engineering program in the United States, is a subset of environmental engineering that applies various branches of science in order to create new technology that aims to protect, maintain, and establish sustainable natural resources. Specifically, natural resources engineers are concerned with applying engineering concepts and solutions to prevalent environmental issues. Common natural resources this discipline of engineering works closely with include both living resources such as plants and animals as well as non-living resources such as renewable energy, land, soils, and water. Natural resource engineering also involves researching and evaluating natural and societal forces. The hydrological cycle is the main component of natural forces and the desires of other people attribute to societal forces. Some historical examples of applications of natural resources engineering include the Roman aqueducts and the Hoover Dam.
  Natural resource engineering degrees require a basic understanding of core engineering classes including calculus, physics, chemistry, and engineering mechanics, as well as additional courses with a stronger focus on applications of natural resources in environmental systems. These specific courses include soil and water engineering, modeling of biological and physical systems, properties of biological materials, and systems optimization.
  The overall purpose of natural resource engineering is mainly categorized as either resource development, environmental management or both. Natural resource engineers often work in a vast variety of environments ranging from urban to rural. Most natural resource engineers can be found working for groups who strive to solve current and future environmental issues such as environmental consulting firms and government agencies.
