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. By planting trees, we return to a more natural and less artificial environment. Birds and other wildlife are attracted to the area. The natural cycles of plant growth, reproduction and decomposition are again present, both above and below ground.
Natural harmony is restored to the urban environment.
Economic Benefits Individual trees have value, but the viability 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. Heating costs are reduced when a home has a windbreak.
