Have you heard of a car running without a fuel? No. Similarly, for survival of every living being requires some sort of 'fuel'. Oxygen serves as the life line for us. Trees and plants generate oxygen by photosynthesis by utilizing the sunlight. It is simply impossible of thinking life without trees. Besides providing oxygen trees provide us with food, furniture, fuel and shelter. Moreover, trees are the friends of humanity. They have marvelous feature, colors of their lives are simply breath taking. Ralph Waldo Emerson said "The wonder is that we can see these trees and not wonder more"Â Ralph Waldo Emerson.
Trees are true friends of humanity. The trees are oxygen providers and are called the lungs of planet. They not only absorb carbon dioxide which is injurious to us but also produces oxygen which is a source of life on our planet earth. With the industrial development and excessive use of fuel like petrol and gas, produces a huge amount of carbon dioxide. Trees are air purifiers they filter polluted air by absorbing the carbon contents. Thus trees decrease the air pollution which keep the environment clean and provide pure air to breath. Trees also play role in lessening the sound pollution. According to United States Department of Agriculture, a properly designed buffer of trees and shrubs reduces the sound pollution by 10 decibels or about 50% as received by human ear. Evaporation from the leaves brings about the formation of clouds; these clouds cause rain and irrigate the land which increases the crop production. Moreover, they also keep the temperature milder. Trees help in increasing the fertility of soil. Roots of trees keep the soil intact and decrease the soil erosion. Trees provide us with beauty and peace of mind. They fill our heart with unexplainable happiness. Green color of trees symbolizes self-respect and well being. They are the essential part of nature. Martin Luther says "For in the nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold and silver".
