Scientific American presents evidence that "high density living" is hardwired in humankind, and as populations grow, density increases.
The report, produced by a team of anthropologists and ecologists, studied 339 hunter-gatherer societies, and found that people tend to live more densely as their populations grow. In fact, "...(f)or every doubling of population, the home ranges of hunter-gatherer groups increased by only 70 percent."
Reporter Tim De Chant says this evidence is very significant:
"Every additional person requires less land than the previous one. That's an important statement. Not only does it say we're hardwired for density, it also says a group becomes 15 percent more efficient at extracting resources from the land every time their population doubles."
