It is a common practice to plant trees and shrubs near the boundary walls of buildings. What purpose do they serve?
Answers (1)
Trees and shrubs are effective in reducing the noise level. Planting trees and shrubs near the boundary walls of buildings helps reduce noise levels and acts as dust catchers and air purifiers apart from adding aesthetic value to the surroundings. Such a decorated line of trees along the boundary of the roadside is also called a sound barrier.
