The main reason we like trees is because they are both beautiful and majestic. No two are alike. Different species display a seemingly endless variety of shapes, forms, textures and vibrant colors. Even individual trees vary their appearance throughout the course of the year as the seasons change. The strength, long lifespan and regal stature of trees give them a monument-like quality. Most of us react to the presence of trees with a pleasant, relaxed, comfortable feeling. In fact, many people plant trees as living memorials of life-changing events.
