Core Concept: Ecosystem Services
Studies on how humans rely on natural surroundings for survival began in the 1980s, and this relationship with natural surroundings is known by the term "ecosystem services". Ecosystem services include water purification, pest control, storm buffers, and other services that increase human quality of life and benefit society. Recognizing the practicality of ecosystems and valuing them in dollars helps social scientists quantify their necessity. This information is then used to adjust and shape policy decisions.
