One of the main challenges facing many coutries is how to maintain their identity in the face of globalization and the growing multi-language trend. “One of the main reasons for economic failure in many African countries is the fact that,with a few important exceptions,mother-tongue
education is not practiced in any of the independent African states." said Neville Alexander.Dutctor of the Project for the Study of Aitemative Education in South Africa at the  University of Cape Town.
In response to the spread of English and  the increased  multi-language trends arising from Immigration . many countries have inuoduced language laws in the laws in the last decade .In some ,the use  of languages other than the national language is banned in public spaccs such as advertsing  posters.  One of the first such legal proviaions was the  1994  " Toubon law'  in France. but the idea hs been copied in many counuics since then. Such efrorts to govern language use are often
dismisscd as futile by language experts . who are well aware of the difficulty of controlling fashions in specch and know  from research  that language switching among bilinguals is a natural process.
It is especiaLly difficult for native speakers of English to understand the desire to maintain the 'purity" of a language by law.  Since the time of Shakespeare . English has continually absorbed
foreign words into its own language. EngLish is one of the most mixed and rapidly changing languages in the world. But the  has not been a barrier to acquiring prestige and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it bas never been the Aryllo-Saxon way of doing things. English has never had a state-controlled
autharity for the language,  similar, for example . to the Academie Francaise in France.
The need to prorect national languages is for most western Europeansa recent phenomenon- especially the need to ensure that English does not unnecessarily take over too many fields.
Public communication, educauon and new modcs of communication promoted by technology,may be key fields to defend.
