Longtime English teacher in Dubai Patricia Ryan discusses her perspective in a TED talk on language death and the question:
Is the world’s focus on English preventing the spread of great ideas in other languages?
This is a significant question with which English language teachers must grapple. What are your thoughts on her perspective?

Thanks for this awesome sharing.I can honestly say that I sometimes ignore my mother tongue and make many mistakes when it comes to using it:( I can express myself freely in English language but my mother tongue is Turkish .I do agree with Patricia’s ideas on English being a global language but sometimes it is a barrier for speakersof other languages.Regards,
