In other countries , trees are destroyed to build housing developments andshopping centers. Saving trees has become a major cultural and economical issue in many ofthe world.
Trees are essential to our survival . They are a major part of the process of photosynthesis. Photosynthesis is the process in which green plants use carbon dioxide to produce oxygen,and oxygen is something all of us need . The fewer trees there are ,the more this affects ourability to breathe.
Trees are also important in the development of many medicines. The mainstream medicalestablishment did not recognize this for many years. However , those who use naturalmedicines have always known how important trees are. Now scientists are agreeing with them. Many drugs come from the leaves of certain trees, along with other herds and plants.

For practical and emotional reasons, we need to preserve ourplanet’s trees.
