one world, one language

What is language?
Language is a set of arbitrary symbols (spoken or written) representing real or imagined things. Practically, you can invent an unlimited number of symbols for the same object. This means you can invent an unlimited number of languages.

How useful is a language?
Language is an important tool for communication. It's usefulness depends on how many people speak a language. For example, if you were the only person on Earth who knows a particular language, that particular language is useless, you can't communicate with it. The more people know and speak a language, the more useful that language is.

Are languages becoming a barrier?
Multiple languages are a normal consequence of the fact that groups of people were separated in ancient times. Now the world has changed, we can communicate instantly with people from all over the world, we can travel almost anywhere on Earth. Languages, which were created to connect people, are now barriers because, if people speak different languages, communication is hindered.

Martin Luther King said:
"Men often hate each other because they fear each other; they fear each other because they don't know each other; they don't know each other because they can not communicate; they can not communicate because they are separated."

What do we need?
We need one language all over the world. This is a necessity, it's not some whim. I believe it's obvious that, if we want to communicate, we need to speak the same language.

Which language?
I believe that we should choose English for the world language, because it's the most practical choice. My native language is not English, so I don't think I'm biased towards it.

What can we do?
I believe that we can change the world for the better. The world has always changed and will continue to change as long as it exists. Languages change too, some languages even die, like Latin. I believe we should start promoting a world language. We can do that by starting to speak the world language as often as we can, with friends, with family.

This should be an international project, with people all over the world supporting it. This can even be a reason to socialize, there could be "one world, one language" parties, in which people would speak English, especially in non-English countries.

This is the first step in uniting the world.
