The scarcity of food will be a serious problem. It is true that our agriculturists have developed new varieties of rice and its per acre production has definiely increased. But the rate of increase in food production cannot keep pace with the rate of population growth. This is because our land is fixed. Besides, families are growing larger in size and breaking into smaller families. Each such family needs a separate house to live in. Also the arable fields are being divided by these smaller families among themselves. Mills and factories are being set up, which occupy a considerable portion of our land. So when we need more land to grow more food to feed more mouths, our land is shrinking day by day. If our population grows at the present rate, a day will come when many people will not find any land to build a house on.
