Earth wire is used as a safety measure to prevent electric shocks in case of leakage of current to the metallic body of appliances. Earthing is essential because the person touching defective appliance (where the live wire comes in contact with the metal body due to break of Insulation or otherwise) does not get a fatal shock and the appliance is saved from being damaged.
