For instance, on the claim that you can reduce your carbon footprint by buying locally produced food, he notes that “eating one less serving of red meat a week achieves the same reduction in emissions as switching to a 100% local diet”.
He is also unimpressed by the current fashion for organic farming in the developing world: apparently if Europe tried to feed itself organically it would need 28 million more hectares of cropland, equal to all the forests in France, Germany, Denmark and Britain.
Paarlberg argues that with the world’s population set to rise to nine billion by 2050, we need an agriculture based on hard science. It’s difficult to disagree.
