1. What do you think isthe reason why historians and anthropologist change the terms First World, Second World and Third World into Global South and Global North?

Explain your answer.​

Because many countries in the Third World were impoverished

Explanation:

The terms the North and the South, when used in a global context, are alternative designations for “developed” and “developing” countries. Together, the North and South constitute virtually the entire global population. As terms, the North and the South emerged during the 1970s, probably simultaneously, and in contrast with each other. This article thus discusses these two terms together.

While the countries that make up the North and the countries that comprise the South share broadly similar economic and historical characteristics with the other countries in their category, there is no precise definition of either term. Two generations ago, the North could have been approximately defined as Europe and its offshoots (such as Canada, the United States, Australia, and New Zealand), but Japan has also, clearly, been a developed country for many years. Several other East Asian countries, including Singapore, South Korea, and Taiwan have shifted into the North in recent decades. While there are no recent examples of countries that have moved in the opposite direction (i.e., to the South from the North), the economic position of Argentina shifted from being one of the richest countries in the world, a century ago, to its middle-ranked position today.
