Why study globalization and development?

Globalization is one of the modern words I have heard of when I was still in grade school and I think it was around that time that the concept was starting to spread and be tried. There was this time that I was asked to write an essay about globalization and I barely have an idea about it. Because of that, I think that globalization and development should be taught in schools. There should be no place for ignorance specially in our world now. We need to know about what is happening not only in the scope of environment we see but also in the other parts of the country and of the world. It is somehow our responsibility to be aware. It is our obligation as a citizen of some place to be able to contribute to a macro level--a bigger level--in which a lot more people can benefit.
