What makes Scandinavia expensive and beautiful is the costs associated with safety, security and quality of life on all levels. But there are things you need to know if you are planning a long stay, e.g. in Sweden (https://sweden.se/society/20-things-to-know-before-moving-to-sweden/).
It not only about tourism and long stays in Scandinavia and the Nordic countries but in general it is how the culture, social life and economy are being entangled and intertwined with nature and the environment.

It concludes with a look to the future of Nordic environmental history.
