Correction part 1

Do fewer languages make life easier or not? (No offensesive, just an essay)

First of all, the variety of languages impedes the communication between people from different cultures. Translation is no longer a prior solution for solving the communication problems and it is not efficient [not sure what you are trying to say here]. Translation is no longer a desirable solution for solving communication problem as it is not efficient. Using different languages is extremely difficult when exchanging information and doing business in this contemporary age.

Moreover, too many languages play as an impede for people who intend to find certain useful materials and references are searching for certain materials for . The Modern knowledge and techniques are mainly recorded by using the widely spread languages, such as English. For one thing, This is to make searching for specific material convenient, for another,  as the information recorded in the mainly used languages can be much more varied compare to any other smaller languages that probably can not provide the exact details.

Further more, many languages may cause some serious social problems - not only in the traditional countries but also in the countries with many cultures. People who speak a differently language may be isolated and alienated [isolate and alienate are pretty much the same thing] by others who speak the same language. Consequently discrimination possibly raises conflicts, which is detrimental for the union and peace of a country.

In conclusion, I reaffirm that this world would be benefited from using less languages. It not only contributes to the world development and integration, but also to the global harmony and stability. Even though more languages means more cultural diversity, it is a fact that people are gradually abandoning less popular languages for more common ones.
