• A properly designed buffer of trees and shrubs can reduce noise by about five to ten decibels — or about 50 percent as perceived by the human ear .

• Trees absorb odors and pollutant gases ( Carbon dioxide , ammonia, sulfur dioxide and e.t.c ) and filter particulates out of the air by trapping them on their leaves and bark .

• A new study shows that tree leaves can capture more than 50 % of the particulate matter that’s a major component of air pollution .
