TREE :
IMPORTANCE OF TREES:
Plant Deciduous Trees on the East and West Sides of Your Home:
Deciduous trees (ones that lose their leaves), planted on the east and west sides, will keep your house cool in the summer and let the sun warm your home in the winter, reducing energy use, according to the U.S. Department of Energy. 
Large deciduous trees planted on the east, west, and northwest sides of your home create soothing shade from the hot summer sun and reduce summer air conditioning costs by up to 35%.
   
You use less energy.
   
The utility company uses less energy, especially at peak demand times.
 
   
Less fossil fuel is consumed by the utility to create the energy.
 
   
Less fossil fuel consumption means less carbon dioxide emissions.
 
   
Please DO NOT leave your lights on when you are not at that place. DO NOT use Harmful Plastics. DO NOT cut the trees. DO NOT travel by vehicles for small distances use bi-cycles. Plant Trees. Educate People. Change you Society and You will experience the  difference in the world!
 
Tree selection:
right tree, right place 
What criteria do you have in mind while selecting your tree? If you want to plant a tree to provide a visual screen in your yard and you have plenty of room, a conifer will do a better job than a deciduous tree, which loses its leaves in the winter. If providing fall color is your goal, then trees like maples, scarlet oak, sweetgum, or for smaller spaces, dogwood or vine maple, may be on your list of trees to consider.
Also, when deciding which kind of tree to plant, make sure you know how big it will get, and have a good idea of how it will fit into the surrounding landscape over time. Realize the tree will need care and maintenance particularly during the first three years after planting, and anticipate how best to prevent lawn mowers, weed whackers, vandals, children, and car doors from damaging the young tree. Know the light requirements your tree will need, and the solar orientation of the site.
Once you’ve decided which kind of tree to buy, look for container-grown, or “balled-and-burlapped” trees. “Balled-and-burlapped” is simply nursery lingo for trees taken out of the ground with a ball of soil around the roots, and then wrapped in burlap for support.
 
Environmental Benefits Of Planting Trees:
   
Trees serve as a natural habitat, which provides support to a wide variety of flora and fauna. They provide a sense of privacy and security to the wildlife, seeking shelter in the woods, apart from providing them with food and nutrients.
 
   
Trees remove excess amount of carbon dioxide and air pollutants present in the atmosphere, including sulfur dioxide, ozone and nitrogen oxide. In return, they give us oxygen required for living life.
 
   
Planting trees is very important to improve the quality of air and reduce its pollution.
 
   
The visual quality of a landscape is improved by planting trees, which, in turn, improves the quality of life.
 
   
Planting trees help reduce ozone levels in urban cities. Even the biodiversity gets enriched in turn.
 
   
Trees control the climate by moderating the effects of sun, wind, and rain. While they moderate summer temperature by providing shade, in winters, they act as windbreaks for your home, thereby helping you save on heating cost.
 
   
Trees reduce soil erosion, because they bind the soil through their roots, which would otherwise have been washed away in rainstorms and flood. Trees also help improve the fertility of soil. Rich soil transfers nutrients to food, which contributes to human health.
 
   
The greenery of trees adds color to the landscape and enhances the picturesque beauty of the environment.
 
   
According to a recent study, houses and properties on tree-lined streets are found to be attractive places to live in. Apart from this, trees and shrubs planted around homes also provide evaporative cooling benefits.
 
   
Trees are great absorbers of noise. Noise pollution can be reduced, to a great extent, by planting more and more trees.
 
   
Planting of trees facilitates better management of flood water. Trees also moderate flood hazards, by allowing the rainwater to percolate into the soil, instead of running over it.
 
   
The demand for clean drinking water can be met by planting new trees. Forests and plant cover naturally slows the runoff of rainwater, thereby filtering it. Once slowed, rainwater seeps down to refill underground storage tanks or aquifers. Also, they prevent water from mixing with the salt water of oceans. This is of immense help, as salty water takes much longer to re-enter the fresh water portion of the hydrological cycle.
