"The farther from the equator, the greater the seasonal swings."
I’m not posting this in spite of its controversial nature—I am sharing this precisely because it raises eyebrows. Many have read this and see elements of environmental determinism while simultaneous recognizing some of its core assumptions. Arctic communities have devastatingly high suicide rates that most agree is in part impacted by the cold weather, the lack of sunshine, or in other words, the physical environment.
Questions to Ponder: How much environmental determinism actually is in this research and its assumptions? How much does latitude impact the human condition? How much of a factor is the environment in shaping cultural patterns? How would you adapt to the physical environment if you lived north of the the Arctic Circle?
