Differences in climate, soil and talent 01 1600ur] result in the production of different commodities in different pairta of the world Bvery country taking part in it can thus enjoy a wider range of commodilina' and can also benefit from other epecialisation:
A
country ge ine by import goods that she could not.pro duce herself and by export goods that she has surplus. She can also specialise in the production of those goods for which she has the greatest comparativa advantage over other countries
Men are more and more dependent on the work of others to give us all we need. To day raw materials used in the factory may come from different parts of the world. The producers have to collect, prepare. and pack into bags which are sent to the manufacturer by exporters and importers. Men have had to be field: for producing the goode, for collect ing and delivering then. The raw materials are now ready to make into finished guoda, The finished goods pass to the whole", walera through the haids of exporters and importers: In the process of international trade the services of the bank, insurance and warehouses are all at work The bank serves for payment for goods by means of a bill of exchange and also issues, letter of credit The insurance gives a most valuable security and The warehouse serves "for etability to commerce

The individual worker is financially weak and by means of monthly subscriptions the unione build up & fund from which small payments can be made to
membera during a strike. The strike is a weapon of last resort and it is advisable to use conciliation and mediation to settle the disputes of workers and employers.
