Green roofs will create the much-needed space for Delhi’s dwindling bird and insect population to revive again. What’s even better, you’ll have butterflies on your roof.Green roofs not only retain rainwater but also moderate the temperature of the water and act as natural filters for any of the water that happens to run off. The government can provide free saplings and encourage rooftop plantation. It can be initiated in government schools, colleges and offices helping the masses inculcate such environmentally responsible gestures.

In Action

We can fight air pollution in Delhi by introducing rooftop plantation all over the capital. This will help us to create a fresh, pollution-free environment especially in cities over polluted and gasping cities like the national capital. In fact, I feel the law should make such environmental gestures like rooftop plantation mandatory in Indian cities.Delhi has turned into a pollution zone so deadly that children in the capital have the lungs of ‘chain-smokers‘, and suffer all the associated respiratory ailments. Living and breathing in Delhi is taking years off their lives, and marking what is left with bronchitis, asthma, sinusitis, coughs, colds and all kinds of chest and throat infections.Tulsi has tremendous environmental benefits as it purifies the air around it. Tulsi gives out oxygen for 20 hours and ozone for four hours a day along with the formation of nascent oxygen which absorbs harmful gases like carbon monoxide, carbon dioxide and sulphur dioxide from the environment.

Results

With a relentless increase in the number of children and infants developing respiratory diseases, doctors have raised an alarm in the capital. Almost all agree that the number of children who need medical attention as a direct result of the capital’s polluted air has risen three times as much in the last decade. The worsening air pollution in the capital has become the primary killer of infants and is slowing poisoning them with every passing day. Not only is the toxic air responsible for the various respiratory diseases that children are developing, but it is also shortening their life span.The government can provide free saplings and encourage rooftop plantation. It can be initiated in government schools, colleges and offices helping the masses inculcate such environmentally responsible gestures.

Impact

Law should make such environmental gestures like rooftop plantation mandatory in Indian cities.Maybe soon there’ll be more like this Kolkata taxi driver who has set up rooftop plantation in his own taxi. And maybe India will soon be like France where rooftop plantation has already been implemented as a law.

Challenges and lessons learned

 With green roofs, water is stored by the substrate and then taken up by the plants from where it is returned to the atmosphere through transpiration and evaporation.A study presented at the Green Roofs for Healthy Cities Conference in June 2004, cited by the EPA, also found that water runoff was reduced by over 75% during rainstorms.
