In 1850, 64% of American workers worked on farms.1 In 1900 there were still 6 million US farms, with an average size of 150 acres.2 By 1920, 30% of US workers still did farm work.3 But after World War 2, the US government adopted policies to reduce the number of farmers and expand the size of farms–for more efficiency, it was said.4 5 6 Today, only 1% of Americans work on farms7 and the number of farms has dropped by 2/3.
Most US farmland belongs to farms that are over 2,000 acres in size, or more than 3 square miles. But along with efficiency came worsening food quality. The so-called “Green Revolution” allowed farmers to apply chemical fertilizers, pesticides and herbicides while ignoring the overall fertility, quality and texture of their soils. Depleted soils subsequently produced less nutritious foods, while accumulating low levels of neurotoxins and carcinogens.
