Greenways and trails not only encourage friends, families and communities to interact with each other and nature, but they also provide a venue for physical activities such as walking, jogging, running, in-line skating and biking. The associated physical and psychological health benefits of these activities are significant. Greenways and trails help to:
A landmark report by the U.S. Surgeon General found that "Americans can substantially improve their health and quality of life by including moderate amounts of physical activity in their daily lives." It also found that "health benefits appear to be proportional to the amount of activity; thus, every increase in activity adds some benefit." Several studies have found that access to public green spaces increases physical activity levels. Recognizing this important concept, the U.S. Government has established the Rivers, Trails and Conservation Assistance Program (RTCA), which serves to help local groups plan and develop new trails, greenways and open space that are close to home and encourage regular physical activity.
A growing body of research suggests that mere contact with the natural world improves psychological health. Green settings have been shown to relieve feelings of anxiety and improve our ability to cope with stressful situations. In some cases, natural spaces provide therapy for conditions such as Attention Deficit Disorder and improve cognitive function and work performance. In addition, greenways, trails and parks provide safe places for kids to play, which is vital in brain development in young children.
Greenways and trails serve as highways for alternative means of transportation. Therefore, automobiles are used less frequently, resulting in lower overall carbon dioxide levels. Additionally, increased tree density along these greenways can mitigate air pollution by filtering pollutants out of the air, and therefore decreasing the number of respiratory illnesses experienced by many people.
Greenways and trails also provide safe routes for pedestrians and bicyclists to travel. This separation from traffic can reduce the number of vehicle-pedestrian and vehicle-bicyclist related accidents.
