Rooftop plantation

The number of children who need medical attention as a direct result of the capital's polluted air has risen threefold in the last decade. It is not just for natural beauty but for our very survival that green roofs must be encouraged all over the city.

Green roofs can reduce heat loss and energy consumption in winter conditions and reduce cooling loads on a building by fifty to ninety percent during the summer. They can filter pollutants and carbon dioxide out of the air to cure asthma. They help filter pollutants and heavy metals out of rainwater, and insulate a building for sound.

The government can provide free saplings to encourage rooftop plantation. It can be initiated in government schools, colleges and offices, helping the masses inculcate such environmentally responsible gestures.
