Autobiography on a tree is very important to understand the true importance of trees in human life. Almost an uncountable number of species of both plants and animals live in the environment that is created by trees. Trees are very vital to the environment as they recycle water and also regulate the level of carbon dioxide in the atmosphere through photosynthesis. Trees not only provide oxygen, home to an enormous number of plants and animals, food, rain, wood and fruits, but also make the world look so beautiful with their presence. Trees are the power-house of evolution which needs to be saved for the smooth running of all the life forms on the planet.
