The Bering Strait, the Strait of Gibraltar, the Darian Gap, there’s probably about a dozen possible megaprojects that I could name that have been proposed but not built. The question is, should they be built? Is having the world connected worth the consequences of doing so?
Massive megaprojects are cool and neat in a testament to man’s will kind of way, but also atrocious for environmental impact I have to imagine. Let’s knock ‘em out as they come up and sufficient need presents itself. Doing shit because it’s cool at the nation-state level does not, imo, have a great track record
