The conclusion most certainly makes sense: There’s more people on Earth that are eating more food than ever before. This, according to a new study published in BMC Public Health, could further drain the world’s natural resources.
“Increasing population fatness could have the same implications for world food energy demands as an extra half a billion people living on the earth,” the studyconcluded.
Leading the Pack in Obesity
The U.S., not surprisingly, leads the pack in obesity and is among the largest drainers of food resources. Researchers used body mass indexes (BMI) and overall population to calculate biomass or overall weight of the nation. “Total biomass by age-sex group was estimated as the product of the number of people in the group and their average body mass.”
Researchers then used “extreme scenarios” to calculate usage of natural resources. They calculated the drain on natural resources if all the countries had BMIs like the U.S. versus if all the countries had BMIs like Japan. These particular countries were chosen because while they are similar socioeconomically, their obesity rates are at two different ends of the spectrum as shown in the study below.
