But, it will be said, as population increases, the price of food must ultimately increase also as the sources of supply in Canada, the Argentine, Australia, and elsewhere are more and more used up. There must come a time, so pessimists will urge, when food becomes so dear that the ordinary wage-earner will have little surplus for expenditure upon other things. It may be admitted that this would be true in some very distant future if the population were to continue to increase without limit. If the whole surface of the world were as densely populated as London is now, it would, no doubt, require almost the whole labour of the population to produce the necessary food from the few spaces remaining for agriculture. But there is no reason to suppose that the population will continue to increase indefinitely, and in any case the prospect is so remote that it may be ignored in all practical considerations.
Returning from these dim speculations to the facts set forth by Kropotkin, we find it proved in his writings that, by methods of intensive cultivation, which are already in actual operation, the amount of food produced on a given area can be increased far beyond anything that most uninformed persons suppose possible. Speaking of the market-gardeners in Great Britain, in the neighbourhood of Paris, and in other places, he says:—
