Have you ever heard of the children’s book, The Giving Tree by Shel Silverstein? It’s a story about a tree that gives a boy everything it has, such as apples, wood and shade, to make him happy throughout his life. Every tree is a giving tree, isn’t it? Trees are wind obstructors, fresh air makers, pollutant reducers, shade producers, and block us from the cold. Trees entertain kids for hours with tree houses and swings.
