How Much Humanity Weighs

The video discusses a study estimating humanity's total body mass at 287 million metric tons, using data from the World Health Organization. This mass is compared to other species like cattle and ants. The study highlights regional differences, with North America having the highest average body mass. It suggests that if all countries had the same average mass as the U.S., it would be like adding 935 million people to the world. The study emphasizes the importance of considering both population size and individual body mass for future public health and resource planning.
