Rain washes the pollutants to the ground. Leaves absorb carbon dioxide from the air to form carbohydrates that are used in the plant's structure and function. In this process, leaves also absorb other air pollutants such as ozone, carbon monoxide, and sulfur dioxide, and give off oxygen. By planting trees and shrubs, we return to a more natural, and less artificial environment. The natural cycles of plant growth, reproduction and decomposition are again present, both above and below ground.
Natural harmony is restored.
Economic Benefits Property values of landscaped homes are 5 to 20 percent higher than those of non-landscaped homes. Individual trees and shrubs have value, but the variability of species, size, condition and function makes determining their economic value quite difficult. The economic benefits of trees can be both direct and indirect. Direct economic benefits are usually associated with energy costs. Air conditioning costs are lower in a tree-shaded home.
