1,000 Times Too Many Humans?
A study that compared humans with other species concluded there are 1,000 times too many humans to be sustainable.
The study, published in the current Proceedings B (Biological Sciences) by the Royal Society, used a statistical device known as “confidence limits” to measure what the sustainable norm should be for species populations. Other factors, such as carbon dioxide production, energy use, biomass consumption, and geographical range were taken into consideration.
“Our study found that when we compare ourselves to otherwise similar species, usually other mammals of our same body size, for example, we are abnormal and the situation is unsustainable,” said Charles Fowler, co-author of the paper and a lead researcher at the National Marine Mammal Laboratory, a division of the National Oceanic and Atmospheric Administration.
