1 billion people in India, or 100 million more than the number of voters we have in India, live in water scarcity! And this number is expected to go up to 5 billion by 2050. This is the appalling statistic that has come out from research by Water Aid on Monday. Club this with the fact that one in every eight deaths in India is attributable to air pollution in India, the Ganga River is far dirtier than what it was a few years back and the health cost of environmental challenges can go up to 3% of our GDP, which is higher than our health budget. We hear Rafale, Ram Mandir, Chowkidar, Chor, Chaiwala but why don't our politicians talk about the environment in their campaign? Why do we find free smartphones, free laptops in election manifestos but why don't we find a roadmap to solve the pollution challenge? This is what we want an answer as Supriya Shrinate discusses India's worst challenge in this India Development Debate.
