> Our food boom has helped create the population boom.

Impoverished populations tend to have a high birthrate, which frequently begets more poverty. I'd like to think we can work to reduce overpopulation through reducing poverty (which includes improving food security) instead of simply relying on Malthus to sort everything out. Call me an optimist.

Again, this seems like a policy problem. Having a robust selection of lower-input/higher-output cultivars would help shield us from the failure of single crops.
