28 THE SHADOW OF THE WORLD’S FUTURE of food-supplies may in this way be increased is obvious. It is not easy, however, accurately to determine to what extent this will ease the situation. What is known of the cod-fisheries shows that the possibilities can easily be over-rated, and we are disposed to think that, taking into account all the facts, the possibilities of exploiting the oceans will not materially alter the situation in respect of man’s fundamental needs. Moreover, however great within the limits of human possibilities this source of food-supply may become, it will always, we venture to think, be small as compared with land-supplies. The experience of such countries as Japan tends to confirm this. To obtain a concrete idea of the areas really needed for agriculture, for forests, etc., for Man’s various needs, unfortunately, we have to depend upon very partial statistics. To get these into due perspective, it has to be remembered that the earth’s entire surface is only 197-05 million square miles, and that the land- surface is only about one-fourth of this. More accurately, and neglecting some portion of the polar areas, it is 52-5 million square miles. Quite a con- siderable portion of this, however, is rocky surface or it is desert, sandy, or barren. And here, again, statistics though good are incomplete. Thus out of a recorded total of 24-13 million square miles, about 7-53 are regarded as productive, 6-25 as unproductive, and the nature of the balance of 10-35 is unspecified. This recorded total embraced areas the populations of which were then roughly 777.6 millions or about 40-9 per cent. of the world’s total at the time. The aggregate area was 46-0 per cent. of the whole. In view of this, and having regard to the characteristics of the countries not included, the proportions furnished by existing statistics may be assumed fairly well to represent the total surface of the earth. On this assumption we obtain, in millions of square miles, the
