In the modern world, a lot of products around are from oil-based derivatives or processed organic compounds. Ranging from clothing, footwear, insulation, cars, computers, phones, etc. People are not aware they are surrounded by oil-based products. Is it possible to replace all these products with alternatives in the quantities the modern world is accustomed to?
Would we need to move back to the middle ages, where there wasn't any electricity as the world production of electrical cable insulation is not possible due to production cannot meet demand? All our communications sooner or later will require plastic insulation on metal wires, so wouldn't there be any more mobile communications? Therefore, if we don't have any oil, will it be the end of computers as the PCBs are made from plastic? Would it be the end of modern civilisation if there wasn't no oil?
