Globalization refers to the increasing integration and interdependence of economies around the world. It involves both the globalization of markets, through the merging of national markets, and the globalization of production, through companies sourcing goods and services globally. The main drivers of globalization have been declining trade barriers through organizations like the WTO, and technological changes like increased internet use. While globalization offers benefits like cheaper goods, critics argue it can also lower wages, harm the environment, and increase inequality between rich and poor nations.
