Grass, trees and plants reduce soil erosion-a major cause of water
pollution by pesticides, fertilizers and sediment.
One tree removes 26 pounds of carbon dioxide from the air every year
and it can produce enough oxygen for a family of four to live on-about
13 pounds annually.
Plants, trees and grass fight pollution and provide storm water control
and shelter for wildlife.
Shrubs, turf and trees reduce noise pollution by up to 50%.
Proper selection and placement of plant material can lower heating and
cooling costs by as much as 20%.
Trees absorb as much as 85% of the sun's direct heat.
Eight average front lawns have the cooling effect of 70 tons of air
conditioning.
Trees can reduce power demand by as much as 59%.
Temperatures around grassy areas are about 25 degrees cooler than
around dead grass or concrete "heat islands."
One large tree can absorb as much heat as several window air
conditioners and can lower temperatures by 10 degrees.
Healthy turf is a strong asset in fire prevention.
