Virtually everyone in the scientific community agrees that ensuring sufficient food supplies for a surging human population, which is set to grow by 2.4 billion by mid-century, will require serious work. Indeed, we have not even succeeded at providing enough food for today’s population of 7.3 billion: Nearly 800 million people currently are starving or hungry, and another couple billion do not get enough micronutrients. But there is no such consensus about how to address the food security problem.

The scientific community is split between two main approaches: “tinker with agricultural details” (TAD) and “mend societal fundamentals” (MSF). While the former approach has support from a clear majority, the latter is more convincing.
