In the past ten years, increasing evidence has supported the assertion that trees benefit human mental and physical well being in myriad ways. After spending time in well-canopied greenspaces, people self-report an increase in energy and feelings of happiness, and experience diminished feelings of anxiety, brain fog, anger, and depression. Trees muffle noise pollution, absorb air pollution, moderate extreme temperatures, and provide shade and sanctuary. Some cities have orchard projects, which plant food trees as a way to provide cheap, local, and fresh food to residents. As urban populations continue to swell, trees and natural areas can no longer be viewed as a luxury, with only aesthetic and beautification value. They are increasingly acknowledged as a core strategy for improving public health and well being, and an essential component of livable communities.
