To produce large quantities of food cheaply, companies look for economies of scale, using chemicals to control weeds and pests instead of more labor-and space-intensive organic options and often packing animals into very crowded spaces.
The cost of this cheap food trickles down in many ways, including food safety issues (14 Americans die every day as a result of food-borne illness); increased use of antibiotics (more than half of all antibiotics used in North America are fed to livestock and 90 per cent are administered to make animals grow faster, not to treat infections); and water pollution (The U. S. Environmental Protection Agency estimates agriculture is responsible for 70 per cent of the country’s water pollution).
“These things have to be important to you in order to get past the price you pay,” Sirois says. “We seem to have no problem paying $50 for Internet each month and $80, $90, $100 for a cellphone each month, so why do we want to pay the least possible for food?”
“We can’t seem to make the connection on a broad scale between food and health. Yes, we eat cheaply and poorly, but it adds to this incredible health expenditure on the other end,” Sirois says.
