In introducing their important review paper on future food security, Ziska et al. (2012) write that “agricultural production is under increasing pressure by global anthropogenic changes, including rising population, diversion of cereals to biofuels, increased protein demands and climatic extremes,” and they say that “because of the immediate and dynamic nature of these changes, adaptation measures are urgently needed to ensure both the stability and continued increase of the global food supply,” the trouble being that we need “more cereals for biofuels, more grain for meat, and more food for the additional two billion people expected by 2050,” and they indicate that “as these demands mount, available resources are becoming strained, with less arable land, less water for irrigation and less energy for fertilizer production.” So what’s the globe’s all-time most ingenious species supposed to do about it?
