Not only do thin people consume fewer resources, transporting slim people takes less energy, say British experts who compared the toll that slim populations versus overweight populations take on the environment. The study, by researchers Phil Edwards and Ian Roberts of the London School of Hygiene and Tropical Medicine’s Department of Epidemiology and Population Health, will appear in the International Journal of Epidemiology.
Because food production is a key contributor to global warming, the authors decided to examine the effects of lean versus heavy peoples on their environments. A lean population, they argue, such as that in Vietnam, consumes 20 percent less food and produces fewer greenhouse gas emissions than a population that is 40 percent obese, such as the United States.
Furthermore, because it takes less energy to transport lighter people, Edwards and Roberts add, transport-related emissions are lower in slim populations. A lean population of one billion people, they calculate, would emit 1,000 million tonnes less than an overweight one.
“When it comes to food consumption, moving about in a heavy body is like Read the rest of this entry »
