The world's only language...

In business and economics we often hear the word "globalization" passed around. And with the inevitable advancements of technology the world is becoming a smaller place. Never before has access to distant parts of the world being more accessible, as it is now in the twenty first century. The United States and Great Britain, specifically referring to England, have spread their culture and language around the world. With the United States being the only world super power right now, and a place full economic opportunity, many individuals from all over the world have fought and struggled to get into America.
Although, English may not have been their first language, they come to America with the knowledge that to survive and compete, and take advantage of all that America has to offer, that they have to be able to comprehend and speak English. By no means am I saying that English is the "best" language in the world, but it is currently the most important. We can see this idea by simply looking at the United Nations, where the official language was once French, but now has changed to English.
It is very rare to go anywhere in the world and not meet someone who does not speak English. English is becoming the world's language. The Guardian stated that there are about 750,000 English words, while only 200,000 German words and relatively speaking only 100,000 French words. I feel this attributes to the sponge like nature of the English language. The ability of the language to adapt 'foreign' words into it like: egg, horse, window and etc, which are not traditional Anglo-Saxon words, but old Norse words. As well as street words and cliches, such as "less is more" and "cool." With the sponge like nature of the English language compelled by the irreversibly trend of globalization the English language is soon going to be the only language spoken in the world. Now, that last statement might be a bit over the top, but there is some truth to it.
We can see this unfolding in the languages spoken in the workplace. The BBC wrote an article about a firm in the United Kingdom, which had banned Welsh being spoken at the work place. Such things are not rare, but quite common. And is indeed, the fact that the English language and culture - the attire of the suit, jeans etc, is no longer going to solely be an Englishman's 'thing,' but that of the world.
