Well, i think that the way who are used the languages now is good because when we are traveling in different countries, we are learning about a other culture and a another religion. Also, we have the opportunity to learn more languages except from our and we can to work in a foreign country for a biggest success and more money.
If in the future most languages disappear, the people won’t understand each other and the life won’t have meaning. We will need much time to learn this language who will stay and anyone will find easy job. Also, won’t be interesting the holidays in a other country.
From this we understand that we need much languages in our life because is not easy to understand all in a language.
