It is important to understand the nature and value of the environment, but in a scientific and logical way. You must understand the physics, chemistry, and biology that go into creating a functioning environment. You also need to rely on people in agriculture, forestry, and natural sciences to help you understand how our engineered systems will affect the ecosystem and its health. There are a lot of things that are affected by the work that environmental engineers do and it is extremely important to consider and be aware of the impacts. In addition, it is also important to document everything. Documentation is how we as engineers prove the value and correctness of our designs.
