Missile man and former President Dr APJ Abdul Kalam, in the role of an environmentalist, has called upon Delhites to be involved in cleaning of the city's lifeline, Yamuna river. The ex-president is a man of his own stature and thinks very deeply. These days Dr Kalam is busy in social works. As regards the river Yamuna, it has been polluted from whereever it is flowing, near Kanpur, Allahabad and Agra by industrial units established there as also the people living there. Near Kanpur Dehat, the dirty water from leather factories is drained in the river. At Allahabad, the devotees who went to have darshan of the Holy River at Sangam, were pained to see dead bodies floating in the river. Probably this has moved people like Dr Kalam to call upon the general masses and the business class people to wake up to save the rivers from further deterioration. Even though there is a cleanliness drive at the national level, yet the people's role in keeping any river clean is equally important. For inspiration, Dr Kalam gave the example of river Ben in Punjab where Baba Balbir Singh took pledge to see the river clean and succeeded. Another example of a river being cleaned by the people is a river in Liverpool, England. A drive by the people saw the river cleaned up of various pollutants. If Dr Kalam's example is followed by majority of Indians, then justice would be done with rivers even without going for government help. It is said in Varanasi itself, dirty water from 17 nullahs flows into the holy river Ganga. In Madhya Pradesh too the rivers are no less getting polluted. Narmada, Betwa rivers are lifeline of the State and should be protected from environmental pollution.
