• Globalization tends to make the world a more homogeneous place. As a result, many communities failed to preserve their old tradition, custom, and culture. Being attracted by the culture of developed nations, many people in under-developed nations have shed their traditional dress, food, and rituals. This is yet another disadvantage of Globalization.
