HOW POPULATION INCREASES 63 applied in estimating the possible population of the whole world?» This is a question which we must examine. In the World Population Conference of August and September 1927, we note that H. Brenier takes strong exception to Prof. East’s estimate of 2-5 acres being applied to the whole world. It may be, he says, merely the figure for the United States, and he declares that the half (?) of humanity does not eat beef, but eats fish, mentioning the great quantities of fresh- water fish in China. Moreover, the soya bean, con- taining far more proteid than beef, 33 per cent. as against about 21, gives quicker returns on a far smaller area, and a more nourishing element. Also in Java, people are living per capita on about one-fifth of an acre, eating rice. We see at once not only how the standard-of-living comes into the question, but also that advances in practical dietetics come into it also. Dietaries differ at least according to climates. Maurel (teste HL. Brenier) estimates that a male weighing 55 kilograms, and performing light work, needs, say, 1650 calories in a hot climate, but as much as 2750 calories in a cold one. If East’s estimate, however, could properly be applied to the entire area of land-surface, 52-5 million square miles, it would indicate that no less than 13,440 millions of inhabitants was the possible limit. But if, on the other hand, it ought to be restricted to the probable total of * productive land,” viz., 31-2 per cent. of the above, the possible population would be only about 4200 millions. One sees from this that we must have regard to the possibilities of a better scheme of culture for the world as a whole in order to estimate its possible population. If the United States proportion of 503 millions of acres of highly improved land, out of a total of 1903 millions, could rightly be taken as representing the
