Inventing a new language for international communication is believed to be a worldwide solution. I agree with that statement, because it will help get more opportunities and this outweighs disadvantages as putting in danger minority languages and culture unique features.
A global language provides prospects for employment, education and overall success. Possibility to reach out for experienced professionals from abroad and being able to study the newest information increase the level of general knowledge of people. Consequently, it leads to opening of more scientific achievements and economic growth as well. Communication of best minds without any barriers has better outcomes, for example medical international guidelines for diseases are being developed by doctors and experts from all over the world, but sometimes the important cases can be excluded, resulting from challenges to present this case in non-native language.
There is evidence that many languages have become extinct. Language is not a collection of words, but reflection of the culture, so loss of culture is not ruled out too. Population of one country can find their national language unnecessary due to a limited use and constrained opportunities, but language shapes a self-identity. However, culture is evolving and shifting and language is a tool that can be deformed due to demands.
For example, neologisms and words borrowed from other languages have only helped the language become more convenient to use, and culture has developed in the same manner.
Despite the fact, that new lingua franca contributes to the extinction of minority languages and cultures, the comprehensive advancement of the global community, following an invention of a new language has a greater importance.
