It is unarguably true that nature provided us with shield that make our environment cool and this is evident in the Image above.
I love admiring the Beauty that nature praying for the aesthetic views the trees and grasses display.
So if you don't have money for fences made with bricks or blocks you can always well go for some trees.
Nature is what give the earth a good fragrance and good smell that makes the fields and flowers full of good fragrance. Nature is everything and full of beauty.
