     One of the min challenges facing many countries is how to maintain their identity in the face of globalization

and the growing multi-language trend "One of the main reasons for eco 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, Director of the Project for the Study of Alternative 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 introduced language laws in the last decade. In some, the use of languages other than the national

language is banned in public spaces such as advertising posters. One of the first such legal provisions the 1994

"Toubon law" in France, but the idea has been copied in many countries since then. Such efforts to govern

language use are often dismissed as futile by language experts, who are well aware of the difficulty of controlling

fashions in speech 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 that 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 has never been the Anglo-Saxon way of doing things. English

has never had a state-controlled authority for the language, similar, for example, to the Academie Francaise in

France.

     The need to protect national languages is, for most western Europeans, a recent phenomenon-especially the

need to ensure that English does not unnecessarily take over too many fields. Public communication, education

and new modes of communication promoted by technology, may be key fields to defend.
