Having one language will help every member of an organization, society or nation to reason together, contribute their asset, energy and potential to develop their society

You just nailed it here. What would it really have looked like if we don't understand our communication with one another? There will be less progress and development even in the societal level because our language is not one. Language has played a very key role in ensuring growth and development in our society.Thank God for a general means of communication which give us a common ground to relate in spite of our varying location.Wish you the very best in this contest.
