Globalization is something that does not sneak up on you. It has been going on since the days of the American Revolution. However, with the internet spurring it on, it seems that globalization has been growing in leaps and bounds. I personally don't see it as a good or a bad thing, it is just the path that the world seems to be going.
The whole idea of globalization in itself is a little bit complicated so I should probably explain it. Plainly stated, globalization is a process by which regional economies, societies, and cultures have become integrated through a globe-spanning network of communication and trade. Now even that is a little bit confusing at first but thankfully history can willingly provide us with an example. After the United States won their independence the people of the certain colonies did not consider themselves as Americans rather they identified themselves as Virginians of Georgian or whatever it may be. It was even written in the Constitution that "these United States" and you know the rest. Not until later was it understood to be one nation with many states instead of a nation made up of states(officially called a Confederacy). But eventually the people of America had to pull themselves together and use all of their strength to fight off the British again in the War of 1812. It is wholly possible that there will come a time where the whole Earth will have to fight together as humans to defend our race from another race. That is one way that globalization could ultimately happen but is highly unlikely it will be the first way that globalization occurs. The other option, which is happening right now, is by business.
The internet has created a world in that markets that a company did not think were plausible are now within reach. Today, the largest and most successful companies are the ones that have many division all over the world. How business will engage globalization is in this manner. Businesses seeking to expand their sales will spread to different countries all over the world. Eventually, all of the major developed nations will have companies in each other. Then, since it is equally to do without them, there will be no tariffs between these countries. The North American Free Trade Agreement is a forerunner to such an idea. Then, as business dictates language there will become a global language ( or group of languages). Just as the Romans conquered their subjects, they forced them to learn Latin. This caused them to lose their own culture and individuality. I see that business( a nicer way of saying MONEY) will force out certain language from "circulation" so to say.
Although this may sound frightening to think about the world's diversity being melted down to only one it is something that cannot be fought. Globalization will eventually consume culture. It is somewhat of a culture Darwinism. The strongest ones will choke out the less desirable ones. But, as I said, it is not something that can be stopped. Although the world's diversity is beautiful, diversity doesn't make any money. And in the end, money win.
