Trees help and cooperate in cleaning the air by purifying it, that’s why they are known as the lungs of the world.
They also provide shade and coolness to the areas where they grow, and many times they become places where children play and enjoy themselves. In forested areas, they serve as the habitat for a great variety of animals and insects.  The tree is a truly wonderful being, even when old, many trees still show great strength and remain standing through wind and storm.
