Globalization is the integration of people, organization and governments of different nations. This process is driven by international trade ( that increases economic interdependence of national economies), emigration and immigration of people in different countries - (hence transmission of ideas, meanings, and values around the world), and communication between people across the globe.
A merit of globalization is that it enables poor societies to gain advanced technologies and information that would help improve their living standards. A demerit of globalization is that it results to dissolution of rare indigenous cultures by the dominant cultures hence reduce global diversity.
