South Carolina has 1 of the 50 cities with the most green space per capita

Green space is beneficial anywhere, but especially in concrete jungles like those found in many U.S. cities. The World Health Organization reports that green areas are essential to both the ecosystem and the mental health of citizens; though the color is fading quickly in urban areas that are cutting down trees and rapidly building on open space. There are, however, some cities across America that are fighting hard to keep green space within their borders.

Using data from the Organization for Economic Co-operation and Development, analyzed by the United Nations Office for the Coordination of Humanitarian Affairs, Stacker considered the 70 U.S. cities with the most green space per capita and then ranked the top 50 by the green space areas devoted to parks and urban regions.

#43. Charleston

- Green space per capita: 3,260 sq. ft.
- Population: 726,770

There are 10 green space hangouts in Charleston that top the rest, according to USA Today. There are more to come, with the Charleston Parks Conservancy, the medical district, and civic and business leaders planning long-term goals for more green space to promote physical activity and community involvement. The chief facility behind the plan, the Medical University of South Carolina, reports green space and human health go hand-in-hand, which is why preserving it is critical.

Some cities have gotten creative in constructing green space within their boundaries. Houston, Nashville, and Des Moines, Iowa, are among the many cities putting large green spaces on public rooftops. Atlanta even has plans to cover some of its highways with parks.

The former commissioner of the New York City Department of Parks and Recreation Adrian Benepe promotes the 10-Minute Walk campaign, an initiative to have a park within a 10-minute walk in all U.S. cities by 2050. Now the senior vice president for the Trust for Public Land, Benepe points to how green space helps the ecosystem. "When I see a tree, I see the work of God because a tree is a remarkable machine," Benepe said. "It does extraordinary things in exchange for very little."

What's more, the health benefits of parks and green spaces in cities are numerous, according to The National Recreation and Park Association. Large parks promote active living, which can reduce the risk of diabetes and heart disease, while research shows even small parks can reduce stress and improve creativity and mental health.
