81. The issue is the productivity and utility of the plants that might be substituted.

Generally speaking, food plants that are more tolerant to weather extremes will have lower caloric productivity. Most of our current high-yield food sources especially wheat and corn) produce best in stable temperate climates. Their productivity goes down as temperature increases or the climate becomes less stable (see Table 8 in this PDF).

This could prompt a general shift towards foods like potatoes, but even there high levels of drought (or alternating drought and flood conditions) will interfere with yields.

Yes, we're adaptable, and we'll keep finding ways to continue growing. Until we can't, of course, but who knows when that might be?
