A World of Polars
In this scenario, the world will develop into just several large unions but not hundreds of countries as nowadays. The European Union will keep growing from now on and will include all the european countries in the near future but finally become an integrated large country. That means there will be no England, German, France, Netherlands and so on. All of them will be just like states of a country called "European Union". At the same time, there will be also Asian Union, American Union, Afican Union, etc.
Each union will have its own army and have just one political government and leader. Within the union, people communicate with each other much easier than nowadays because of the development of technology of media, Internet, transportation and so on. Each union has its own language and one single type of culture. As we know, even in one single country, different districts may have some differences in life style such as food, clothes, living, travelling, etc. But the mainstream is almost the same.
Companies in each union will do business with each other with better opportunity than with companies in other union such as lower taxes, cheaper transportation fee, shorter time, faster communication and so on. Each union protects its own economics and natural resources. So energy shortage maybe become one big problem to certain unions. Because the distribution of natural resources is not so balanced that make sure each union has all kinds of sufficient resources. Maybe one union has lots of water resources while another has much more abundant oil. So among different unions, the exchange or trade of these resources will become the most important business trade.
Internet will develop into larger network within each union. The speed of such network will be faster but the different standands of interfaces between different unions will become the barrier of the cheap and fast communication through Internet. The TV will develop into two main categories, one is union and the other is global. The former one will take the major part and provide more information within the union and the latter just opens a vision for the people what is happening in other unions.
