All of us love trees! By providing shade and evaporative cooling, trees also affect local temperature - urban trees even more than rural ones. Clusters of urban trees can cool ambient air temperature  by 10 degrees, reducing local energy demand for air conditioning by 10 to 50 per cent. Moreover, the energy saved reduces global warming by about 15 times the amount of CO2 absorbed by those trees.

In Bangalore, to plant saplings in your locality  contact Janet S K Yegneswaran, president, Rajanet Yegneswaran Charitable Trust. Phone : 9845449703 or visit www.treesforfree.org.

Tree planting is very easy. You can also visit a nursery which will help you out. A good one is the Lal  Bagh nursery, the UAS Department of Horticulture one, or the Association for the Physically Disabled one, APD.
Planting trees has a cumulative effect; each tree you plant will provide benefits and joy for many years. For example, if only 100,000 people each plant a tree this year, the trees will start absorbing over a million pounds of CO2 annually in the year 2010. But if the same people plant a tree every year from now until 2010, the trees will absorb over 20 million pounds of CO2 in that year.
