Globalization have a lot of effects, one of them is the effect on people's languages. As human all over the world are able to communicate very easily by new technologies, which mainly use English, some experts predict that some languages might disappear and English will be the global language.
Some people claim that English will continue its spreading, since it is the language which dominated new technologies as computer and Internet.However it is not completely true.Actually,these products have a wide range of languages in order to be worldwide marketed. for instant, I can change the system in my computer into Arabic easily.In addition, there are thousands of Arabic websites and search engines are available in Arabic.
Another argument is that English may not replace other languages, but it effects them.Although it is true,it also happens the other way around. English has been effected by other languages ,too. As a result of those effects English has a major change.so, maybe after 50 years it will be so different from what we are learning now.
In conclusion, every day languages are changing as rapid as our world is. And the number of spoken languages is decreasing. From my point of view, every language faces the challenge of developing and surviving, even English does.I don't think English will dominate the world. If the global language existed one day, it probably would be mixed from different languages all around the world.
