Why would Norway starve without oil exports? Surely they would figure something else out, its neighbors are not sustained on oil exports so why wouldn't Norway be able to too?
Norway has very diffrent terrain from neighbouring Sweden, she is practically all coastline. Not much easily logged forrest, no big lowland plains for large scale farming
Norway has a lot of fishing going on, it was their main export before oil.
They were a very poor country before exporting oil.
True but coastal fishing is all but gone. Now they are competing with Russia, China and Japan on international waters.
