The perplex tackling of Bangladeshi illegal immigrations into India will be more pronounced due to global warming, felt Meghalaya Additional Director General of Police Kulbir Kishen. Presenting a paper at a two-day national seminar in Shillong on Saturday, the ADGP anticipated a bigger problem, if scientists' prediction about global warming is to be believed. Due to global warming, a one metre rise of the ocean water will swamp 25 per cent of Bangladesh land and those displaced Bangladeshis will look up and rush to India, stated Kishen. Giving the comparative statistics of Bangladesh population density of 1,000 per square kilometre and India having 103 inhabitants per square km, Kishen opined that this will be a serious security concern for India particularly in the North East. The national statistics show that one lakh Bangladeshis who entered our country legally have vanished and never gone back. This multiplies the problem of illegal migrations especially when Bangladesh itself is denying this known fact, stated Kishen. Referring to the present spate of Bangladeshi illegal migration to India , Kishen also bemoaned Bangladesh's constant denial to huge presence of Bangladeshi nationals in India during the numerous bilateral dialogues of the two countries. Apt in pointing Bangladesh fundamentalist elements involvement in terror activities and other misdeeds, Kishen said, HUJI has been attributed to the serial blasts in the country while other elements supported by the ISI are pumping counterfeit Indian notes to our country. The trend is a security concern because the cases has been rising in the past couple of years, stated the ADGP, even as he suggested for a serious diplomatic follow up border management.
