orkers with a view of natural elements, such as                                trees and flowers, experienced less job pressure, were more satisfied with their jobs and reported fewer ailments and headaches than those who either had no outside view or could only see built elements from their windows.

In one study of college students under stress from an exam, views of plants increased positive feelings and reduced fear and anger.

Green spaces also contribute to a healthier environment and foster a sense of community, making them particularly valuable in inner-city neighborhoods.

One tree can remove 26 pounds of carbon dioxide from the atmosphere annually, equaling 11,000 miles of car emissions; and releases enough oxygen each day to supply a family of four.

Landscape plants, including shrubs and turf, remove smoke, dust, and other pollutants from the air. One study showed that 1 acre of trees has the ability to remove 13 tons of particles and gases annually.
