Sweden is not less dependent on global civilization than other countries. Is Sweden a net food importer?
Using climate change as an argument against building any long-term infrastructure is insane, and is probably anti-nuclear motivated thinking. What are the odds I find such doom-saying in the discussion about a bridge being designed to last 50 years? Oh gee, no point building a bridge that lasts 20 years since we'll all be dead by then, right? Tell all the architects and construction firms to stop building apartment buildings to last more than 20 years, right? Yeah right. This extreme sort of doom-saying is reserved for discussions about infrastructure planning that is opposed by the doom-sayer for some other unstated reason.
