They help clean our air, stabilize our weather, keep water flowing properly and much more. These environmental benefits lead to a better quality of life for Georgians.
Cleaner, Cooler Air
- Trees trap lung-damaging dust, ash, pollen and smoke from the air.
- Shade from trees reduces temperatures and helps keep air pollutants from becoming even more volatile.
- Most importantly, trees produce oxygen and absorb carbon dioxide. Studies show one acre of trees produces enough oxygen for 18 people every day.
- According to American Forests, the forests in Atlanta remove about 19 million pounds of air pollutants each year, worth about $47 million a year.
- Trees absorb and store an annual average of 13 pounds of carbon each year. Community trees across the United States store 6.5 million tons of carbon per year, resulting in a savings of $22 billion in control costs.
Research demonstrates that urban heat islands change weather patterns. This can alter the amount and duration of local and downwind rainfall patterns. Urban trees lessen the impact of the urban heat island effect and reduce changes in weather patterns.
Trees act as natural water filters and help significantly slow the movement of stormwater. This lowers total runoff volume, soil erosion and flooding.
- Infiltration rates for forested areas are 10-15 times greater than for equivalent areas of turf and grass.
- During a heavy rain, a healthy forest can absorb as much as 20,000 gallons of water in an hour.
- This important function of trees and canopy cover allows communities to spend less money developing additional stormwater management infrastructure.
- Many municipalities are now charging businesses and homeowners a stormwater utility fee based on the amount of impervious surface at their location.
