Eat more diverse foods. Large monocrops are a huge part of this problem, both in the field and in the farmer’s pocket book. Commodity crops are are the mercy of many more forces working against the farmer, and the narrow margins help push people into expediencies. Four commodity grain crops are most of our volume, and if one develops a pernicious enough pest or pathogen we are truly fucked.

So eat weird fruits, vegetables, legumes. Get used to multigrain bread.
