At a basic level, most of us wish for pretty standard things – food, shelter, clothing and some clean air that we can breathe. Is it really too much to ask for? Air pollution has been the talk of the town, with 13 Indian cities being ranked in a list of the world’s most polluted cities. While we understand that levels of pollution in certain areas are high, we lack hard data. How does pollution flow? Does a green cover provide complete protection from pollutants? Low-cost air quality sensors may help provide the answers to these questions. They cannot compare to the government’s heavy-duty, but often inadequate and poorly-placed, sensors. But, the supplementary monitoring they provide can address pollution at a local level. Is a collaborative effort of this kind what we need to combat the deadly menace of air pollution? The Intersection finds out.
