Trees keep our air supply fresh by absorbing carbon dioxide. Trees lower air temperatures by evaporating water in their leaves. Trees cut down on noise pollution by acting as sound barriers. Trees provide shade and shelter, reducing yearly heating and cooling costs significantly. Tree roots stabilize the soil to prevent erosion.
Trees provide food and shelter for wildlife.
But trees can't do it alone. They need our help to survive. Trees need pruning, fertilizing, and watering in order to thrive. Trees don't reach their most productive stage of carbon storage for about ten years, and many trees never survive that long. We are a world of machines, cars, airplanes, factories, and electric generators.
