One language
Today on earth we have a lot of languages.Each of them is unique in own way.But today more popular language is English.And if we had only one language,it will be plus or minus.People are argue about this.
First type.They think that speaking in one language is good,because communicate with other countries will be easier and people will never forget your language.Besides we can improve on the economy.
Second type.In this type people said that speaking in only one language is bad,because other languages will disappear.Furthermore people will lost your interest to culture.Then lose interest in the country.
In conclusion,I want to say that speaking in other language will be better then speaking only on one language.Because keep culture,language is very important for me.And I think that every country must be keep your language and they can talk to any languages as they want.
