"As social values shift to a more holistic perception of our relationship to nature, so will our expectations shift to a greater desire to complement our urban lifestyle with elements of nature." (Miller, 24)

"Urban residents desire urban trees, parks, and forests for a variety of reasons. We are a species that evolved from the natural world and find it difficult to live without some contact with nature. As we become more urban in our ways of living, the desire for contact with nature will increase rather than decrease. This desire will manifest itself in an increased demand for urban tree and forest amenities as we seek to enhance the quality of life in our cities." (Miller, 25)
