By diverting food crops into fuel and inflating demand for grain and vegetable oil, Trump’s jacked-up mandates will increase food prices, food shortages, and food insecurity. They’ll also accelerate deforestation and greenhouse gas emissions, inducing the world’s farmers to clear tens of millions of acres of new fields to exploit the higher prices for their crops. At the same time, they’ll inflate demand for fertilizer that’s already in short supply because of the Iran war, further increasing global food prices as well as corn-country pollution.
