Fifty years ago, a billion people were undernourished or starving; the number is about the same today. That’s actually progress, since a billion represented a third of the human race then, and “only” a sixth now. Today we have another worry: roughly the same number of people eat too much. But, says Julian Cribb, a veteran science journalist from Australia, “The era of cheap, abundant food is over.” Like many other experts, he argues that we have passed the peak of oil production, and it’s all downhill from now on. He then presents evidence that we have passed the peaks for water, fertilizer and land, and that we will all soon be made painfully aware that we have passed it for food, as wealthy nations experience shortages and rising prices, and poorer ones starve.
