There are many ways to describe globalization, but in a nutshell, it refers to the process in with people, corporations, governments, and nations are able to connect and work in synergy. A great example of globalization is the internet, as it was responsible for allowing people from every corner of the world to be able to communicate with each other in an instant.
The process of buying and selling goods from all corners of the globe is part of the globalization process. The first time that an item from the Middle East was brought into the western world, was a moment that contributed to globalization. The first time that a region exported cocoa beans to another continent, this was also globalization.
Any kind of enhancement that is brought from one region to another is part of the process of globalization and we have come very far with this phenomenon. We are living in a globalized world and we are now able to understand different cultures without having to visit them thanks to the technological advances that make this process so much easier.
