Paarlberg, an economist, takes issue with the slow-food movement, which emphasizes organic and locally sourced food. He shows that without modern, science-based farming, it would be impossible to provide adequate nutrition at affordable prices either in the United States or globally. In his view, popular critiques of industrial farming are often wide of the mark; in truth, technological advances are making farming less damaging to the environment.
Precision agriculture utilizing satellite positioning, drone-based sensors, and machine learning allows farmers to produce more food using less water, less energy, and fewer chemicals. Paarlberg highlights plant-based protein as a substitute for meat and dairy as yet another science-based innovation working in the same direction.
