To these restrictions on her trade Japan’s answer was the plan for creating a vast Asiatic empire at the expense of China and of the Western imperialist powers. The result was war. What will happen when India and China are as highly industrialized as pre-war Japan and seek to exchange their low-priced manufactured goods for food, in competition with Western powers, whose standard of living is a great deal higher than theirs? Nobody can foretell the future; but undoubtedly the rapid industrialization of Asia (with equipment, let it be remembered, of the very latest and best post-war design) is pregnant with the most dangerous possibilities.
It is at this point that internationally organized scientists and technicians might contribute greatly to the cause of peace by planning a world-wide campaign, not merely for greater food production, but also (and this is the really important point) for regional self-sufficiency in food production. Greater food production can be obtained relatively easily by the opening up of the earth’s vast subarctic regions at present almost completely sterile. Spectacular progress has recently been made in this direction by the agricultural scientists of the Soviet Union; and presumably what can be done in Siberia can also be done in northern Canada. Powerful ice-breakers are already being used to solve the problems of transportation by sea and river; and perhaps commercial submarines, specially equipped for travelling under the ice, may in the future ensure a regular service between Arctic ports and the rest of the world. Any increase of the world’s too scanty food supply is to be welcomed.
But our rejoicings must be tempered by two considerations. First, the surpluses of food produced by the still hypothetical Arctic granaries of Siberia and Canada will have to be transferred by ship, plane and rail to the overpopulated areas of the world. This means that no supplies would be available in wartime. Second, possession of food-producing Arctic areas constitutes a natural monopoly, and this natural monopoly will not, as in the past, be in the hands of politically weak nations, such as Argentina and Australia, but will be controlled by the two great power systems of the post-war period—the Russian power system and the Anglo-American power system. That their monopolies of food surpluses will be used as weapons in the game of power politics seems more than probable. ‘Lead us not into temptation.’ The opening up of the Arctic will be undoubtedly a great good. But it will also be a great temptation for the power politicians—a temptation to exploit a natural monopoly in order to gain influence and finally control over hitherto independent countries, in which population has outstripped the food supply.
It would seem, then, that any scientific and technological campaign aimed at the fostering of international peace and political and personal liberty must, if it is to succeed, increase the total planetary food supply by increasing the various regional supplies to the point of self-sufficiency. Recent history makes it abundantly clear that nations, as at present constituted, are quite unfit to have extensive commercial dealings with one another. International trade has always, hitherto, gone hand in hand with war, imperialism and the ruthless exploitation of industrially backward peoples by the highly industrialized powers. Hence the desirability of reducing international trade to a minimum, until such time as nationalist passions lose their intensity and it becomes possible to establish some form of world government.
As a first step in this direction, scientific and technical means must be found for making it possible for even the most densely populated countries to feed their inhabitants. The improvement of existing food plants and domestic animals; the acclimatization in hitherto inhospitable regions of plants that have proved useful elsewhere; the reduction of the present enormous waste of food by the improvement of insect controls and the multiplication of refrigerating units; the more systematic exploitation of seas and lakes as sources of food; the development of entirely new foods, such as edible yeasts; the synthesizing of sugars as a food for such edible yeasts; the synthesizing of chlorophyll so as to make direct use of solar energy in food production—these are a few of the lines along which important advances might be made in a relatively short time.
Hardly less important than regional self-sufficiency in food is self-sufficiency in power for industry, agriculture and transportation. One of the contributing causes of recent wars has been international competition for the world’s strictly localized sources of petroleum, and the current jockeying for position in the Middle East, where all the surviving great powers have staked out claims to Persian, Mesopotamian and Arabian oil, bodes ill for the future. Organized science could diminish these temptations to armed conflict by finding means for providing all countries, whatever their natural resources, with a sufficiency of power.
Water power has already been pretty well exploited. Besides, over large areas of the earth’s surface there are no mountains and therefore no sources of hydro-electric power. But across the plains where water stands almost still, the air often moves in strong and regular currents. Small windmills have been turning for centuries; but the use of large-scale wind turbines is still, strangely enough, only in the experimental stage. Until recently the direct use of solar power has been impracticable, owing to the technical difficulty of constructing suitable reflectors. A few months ago, however, it was announced that Russian engineers had developed a cheap and simple method for constructing paraboloid mirrors of large size, capable of producing superheated steam and even of melting iron.
This discovery could be made to contribute very greatly to the decentralization of production and population and the creation of a new type of agrarian society making use of cheap and inexhaustible power for the benefit of individual small-holders or self-governing, co-operative groups. For the peoples of such tropical countries as India and Africa the new device for directly harnessing solar power should be of enormous and enduring benefit—unless, of course, those at present possessing economic and political power should choose to build mass-producing factories around enormous mirrors, thus perverting the invention to their own centralistic purposes, instead of encouraging its small-scale use for the benefit of individuals and village communities. The technicians of solar power will be confronted with a clear-cut choice. They can work either for the completer enslavement of the industrially backward peoples of the tropics, or for their progressive liberation from the twin curses of poverty and servitude to political and economic bosses.
The storage of the potentialities of power is almost as important as the production of power. One of the most urgent tasks before applied science is the development of some portable source of power to replace petroleum—a most undesirable fuel from the political point of view, since deposits of it are rare and unevenly distributed over the earth’s surface, thus constituting natural monopolies which, when in the hands of strong nations, are used to increase their strength at the expense of their neighbours and, when possessed by weak ones, are coveted by the strong and constitute almost irresistible temptations to imperialism and war. From the political and human point of view, the most desirable substitute for petroleum would be an efficient battery for storing the electric power produced by water, wind or the sun. Further research into atomic structure may perhaps suggest new methods for the construction of such a battery.
Meanwhile it is possible that means may be devised, within the next few years, for applying atomic energy to the purposes of peace, as it is now being applied to those of war. Would not this technological development solve the whole problem of power for industry and transportation? The answer to this question may turn out to be simultaneously affirmative and negative. The problems of power may indeed be solved—but solved in the wrong way, by which I mean in a way favourable to centralization and the ruling minority, not for the benefit of individuals and co-operative, self-governing groups. If the raw material of atomic energy must be sought in radioactive deposits, occurring sporadically, here and there, over the earth’s surface, then we have natural monopoly with all its undesirable political consequences, all its temptations to power politics, war, imperialistic aggression and exploitation. But of course it is always possible that other methods of releasing atomic energy may be discovered—methods that will not involve the use of uranium.
In this case there will be no natural monopoly. But the process of releasing atomic energy will always be a very difficult and complicated affair, to be accomplished only on the largest scale and in the most elaborately equipped factories. Furthermore, whatever political agreements may be made, the fact that atomic energy possesses unique destructive potentialities will always constitute a temptation to the boy-gangster who lurks within every patriotic nationalist. And even if a world government should be set up within a fairly short space of time, this will not necessarily guarantee peace. The Pax Romana was a very uneasy affair, troubled at almost every imperial death by civil strife over the question of succession.
