With the present rates of growth in population at around 3 percent every year and no effective population control policy, no government will ever be able to provide health, education and public transport to the citizens. Successive governments have been spending billion of rupees on population welfare programmes to create awareness among people without any significant success. The illiterate poor are having five to six children on average considering each new child an addition to breadwinners of the family. The government needs to follow the one-child-per-family policy like China to control our population in the next 10 to 20 years or offer a handsome financial incentive to poor families for having no more than two children. In this country, where the poor are selling their organs for money, the financial incentive may well be a successful tool of population control. -ENGR S.T.
