The World's Present Supply of Calories and Protein, or Making Do with the Present Food

Before looking at limits and potential production of food, I take the conservative tack: I look at present, actual production by farmers. To learn whether we already grow enough food to sustain ten billion, I first examine the calories and protein reaching people today. I next calculate the calories and protein in the world's grain and oilseeds. Finally, I inventory all that agriculture produces plus the feed draft animals consume.
