Trees

         Trees help us breathe and provide a home for quite a few diverse kinds of animals and insects. They are the largest and longest living organisms on earth. To grow tall the tree has become a miracle of engineering and a complex chemical factory. It is able to take water and salts out of the earth and lift them up to the leaves, sometimes over 400 ft above. By means of photosynthesis the leaves combine the water and salts with carbon dioxide from the air to produce the nutrients which feed the tree. In this process, as well as wood, trees create many chemicals, seeds and fruit of great utility to man. Also, trees provide refreshing shade.

        Apart from the above, trees are effectively the lungs of the environment. They take much of carbon dioxide from the atmosphere and release oxygen via photosynthesis. They also store carbon in their roots, trunk, branches and leaves. Carbon makes up 50% of the weight of the wood in a tree. Therefore, the greenhouse gas load is reduced and effects of global warming are also brought down. Further dead trees that get buried in soil eventually provide fossil fuels like coal, gasoline products, etc. Among all, trees have an indisputable role in bringing rain to earth. Moreover, they provide a cover over the top surface of earth preventing excessive heating up by solar rays.

         Trees provide the human species with a constant supply of oxygen. This oxygen, which humans in turn utilize for survival, is produced through trees as they intake various amounts of carbon dioxide, which humans exhale.
