The question arises, “How much may this be increased?” The answer to this question depends, however, upon the standard-of-living assumed to be necessary, and upon future advances in the art of agriculture. The matter will be referred to again later. It is sufficient here to observe that, as any population-limit is approached, the poorer lands will necessarily be more and more included in the agricultural areas. In this connection it is proper to note again that out of the recorded total of 24-13 million square miles of the earth’s surface, no less an area than 6-25 million square miles are classed as “unproductive,” and 10-35 million square miles are “ unspecified ”’: this out of a total land-area of 52-5 million square miles.
