(Phys.org) —A team of researchers in France, has, for the first time, calculated the Human Trophic Level (HTL)—a number that indicates the proportion of the diet as it relates to the food chain. In their paper, published in Proceedings of the National Academy of Sciences, the researches describe their efforts to combine demography, ecological impacts and socioeconomics to determine the HTL for various groups living around the world, which led them to calculating a worldwide global average.
