cons of division of labour

cons of specialisation and trade

- If a region over-specialises and their specialist industry shuts down, workers will have no other work, leading to unemployment e.g. miners in the 1980s after the mines were shut down - Countries can over-specialise and deplete their natural resources e.g. Saudi Arabia is slowly running out of its oil reserves - We become vulnerable because if people specialised in producing a certain good or service go on strike or stop trading, we’re left without the goods and services we need E.g. when train drivers strike the rest of us can’t get to work or school
