How many of us have considered how increased body weight impacts the environment? Statistically speaking, “a world of persons weighing 198 lbs has 29% more mass than a world of persons weighing 154 lbs; this extra 44 lbs per person results in proportionate increases in demand for resources and increased stress on the environment. In 2000, the extra 10 lbs weight of an airline passenger compared with 1990 required more than 350 million additional gallons of fuel to carry the extra weight with the production of an extra 3.8 million tons of carbon monoxide. Increasing body size requires adjustments in all resources, with an estimated cost of $2.6 trillion per year.” Curious to learn more about how we affect the world’s resources?
