Passage for Exercise-61

Read the following passages and answer the questions that follow:

    At the end of 1957 there were about 2740 million people on earth, By A.D. 2000 it is estimated that the world population will have increased to about 4400 million. The difficulty then will be to feed all the mouths.

    The only other living things that have a way of life that can be compared with that of man are the bees, ants, wasps and termites. They are social creatures that have solved the problem of keeping a balance between population and food supply. How have they done it?

    Let us examine the community life of termites (or white ants as they are commonly called). First of all, we should remember that termites have been on the earth for something like 200-million years, while man has existed as a social animal for less than one million years. Termites have therefore had much longer to deal with
this problem of life and death than we have. For this reason, too, they are far more advanced than man. Perhaps we should say, for more ruthless.

    The workers and soldiers in a termite nest are cither males or females that are fed and treated in such a way that they cannot have any offspring. Only a select few we call males and queens are allowed to reproduce themselves. But even the latter are not allowed to breed as they like. During the winter, for instance, the queen
does not lay any eggs at all because she is not given sufficient food. When warmer weather arrives in spring, she is well-fed and then days hundreds of eggs. As soon as the workers decide they have eggs, her food is cut down again and she stops laying. She also Stops laying in times of drought when little food is coming in.

    If the drought is prolonged, the workers eat any eggs that may be in the nest to prevent the arrival of more mouths to feed. At times they even become cannibals by devouring some of the young to keep the rest of the community going.

    Of course, human beings cannot imitate termites in their cold-blooded method of population-control. Man will have to find some other way of solving the problem.
