How to beat the rising temperature? Answer lies in planting more saplings. Trees are natural regulators of carbon dioxide in the atmosphere. Radiant energy from the sun is absorbed or deflected by leaves in summer. Temperature in the vicinity of trees is always cooler than when away from trees. By planting trees in the cities, we can minimize the heat-island effect caused by pavement and buildings in commercial areas. By planting trees, we can return to a more natural, less artificial environment. One hectare of trees can absorb 3.5 tonnes of carbon di-oxide and release two tonnes of oxygen. All one has to do is to nurture a tree like a child for a year and it takes care of itself and all of us for hundred years.
