Fat Flares, Slim Hips, Low Carbon?

A study at the London School of Hygiene and Tropical Medicine makes a link between diet and carbon emissions - read the BBC report here

Apparently we are using 19% more food than we were in the 1970s and this could equate to an extra 60 mega-tonnes of greenhouse gas emissions a year. The calculations include the extra fuel related emissions needed to transport the generously proportioned Britons of the twenty first century.

Professor Alan Maryon-Davis, president of the Faculty of Public Health said "In the 1970s we had bigger portions of vegetables and smaller portions of meat and there's been a shift in the amount of exercise we do."

Eating less and walking or cycling more is of course good for the environment and our own and society's chances of survival but making links to the 1970s as the report and the BBC story do is rather misleading.

The British population was slimmer in the 1970s because it was poorer, smoked more, worked longer hours and most of the work was hard manual labour associated with heavy industries that pumped tonnes of carbon dioxide into the atmosphere.

The incidence of obesity in children is higher than it was in the 1880s but you wouldn't want to send them down mines or up chimneys to work off the flab.

Systems thinking, as I am always keen to point out, reveals that a gain in one part of the system is always paid for by a loss in another part. While I'd welcome a reduction in food consumption and hence average weight, I wouldn't want to go back to wearing flares and tank tops even though I am an avid fan of prog rock.
