Totally agree regarding biking, walking, trees, mountains, and will add lakes. Though it does only lightly touch on social structures of traditional societies, you may enjoy reading "The Secret of Our Success: How Culture Is Driving Human Evolution, Domesticating Our Species, and Making Us Smarter" by Joseph Henrich. I also found classic texts of social and political anthropology to be very worthwhile for understanding human societies. Ted Lewellen's "Political Anthropology: An Introduction" is a good starting point.
