Conscientious food shoppers who want to affect change in our food system should find a campaign to support, say Allison Aubrey and Eliza Barclay:
“The biggest food companies in the world — think Nestle, PepsiCo, Mars, Smithfield, Cargill, General Mills, Unilever, Coca-Cola, Kellogg — are the major players in the food system. They control the supply chain from the raw materials to the packaging, and set the labor and environmental precedents of much of what we consume.
“There are now a wide range of campaigns aimed at pushing these global companies to respond more directly to consumers’ concerns about everything from antibiotics to greenhouse gas emissions to labor abuses.
“We’d argue that these campaigns — which have a growing number of victories under their belts — may have a bigger impact than your individual choices at the supermarket.”
