History on Trees & why they are important

         This blog we have started at alpha shows you lots of different activities and projects we do. It also gives you a lot of different information on things we thing would be interesting or helpful to learn. I realized that out of all these things none of them have involved one of the longest living, most important plant known to mankind, the tree. We all know trees are all around us and they are an important role in our living but do we really know how important they are?

        Since the beginning, trees have given us two of life's needs, food and oxygen. As time went on, they provided additional things as shelter, medicine, and tools. Today their value continues to increase and even more benefits of trees are being discovered. We all can look around and spot a tree because we know what they look like, but not everyone knows what the parts of a tree.
    
        The roots are the trees platform that grows below ground which holds up the trunk. The trunk is the tower of the tree which usually grows more then 10 feet and possibly beyond 100. The trunk has many parts to it  from the inside out in order starting with the heartwood, xylem/sapwood, cambium, phloem/inner bark, and last the outer bark. The 10 most common trees in the united states today are Red Maple, Loblolly Pine, Sweetgum, Douglas fur, Quaking Aspen, Sugar maple, Balsam Fir, Flowering Dogwood, White Oak, and Lodgepole Pine.

         Besides trees giving us oxygen there are many needs for them.
