Michael Pollan in the NYT Magazine:
It may surprise you to learn that among the issues that will occupy much of your time in the coming years is one you barely mentioned during the campaign: food. Food policy is not something American presidents have had to give much thought to, at least since the Nixon administration — the last time high food prices presented a serious political peril. Since then, federal policies to promote maximum production of the commodity crops (corn, soybeans, wheat and rice) from which most of our supermarket foods are derived have succeeded impressively in keeping prices low and food more or less off the national political agenda. But with a suddenness that has taken us all by surprise, the era of cheap and abundant food appears to be drawing to a close. What this means is that you, like so many other leaders through history, will find yourself confronting the fact — so easy to overlook these past few years — that the health of a nation’s food system is a critical issue of national security. Food is about to demand your attention.
Complicating matters is the fact that the price and abundance of food are not the only problems we face; if they were, you could simply follow Nixon’s example, appoint a latter-day Earl Butz as your secretary of agriculture and instruct him or her to do whatever it takes to boost production. But there are reasons to think that the old approach won’t work this time around; for one thing, it depends on cheap energy that we can no longer count on. For another, expanding production of industrial agriculture today would require you to sacrifice important values on which you did campaign.
