Is eating local produce actually better for the planet?

Think that eating local will help save the planet? Think again. Most emissions come from food production, not transportation

In June 2005, four women spoke at a San Francisco celebration of the first World Environment Day in North America. The Bay Area locals – Jen Maiser, Jessica Prentice, Sage Van Wing and Dede Sampson – invited the audience to join them in a local food challenge: spending the next month eating only food produced within 100 miles (160km) of their homes.

Although the concept of eating locally was not new – the farm-to-table movement had kicked off in the 1960s and 70s as hippies protested processed foods and Alice Waters opened the first farm-to-table restaurant, Chez Panisse, in Berkeley, California – these women gave it new life with a new name, calling themselves “locavores”. In his 2006 book, The Omnivore’s Dilemma, Bay Area local Michael Pollan also advocated for the local food movement, and by 2007 the Oxford American Dictionary had dubbed “locavore” its word of the year.
