Geography

The Global South refers to the socially and economically less-developed southern half of the globe. 95% of the Global North has enough food and shelter, and a functioning education system. In the South, on the other hand, only 5% of the population has enough food and shelter. It "lacks appropriate technology, it has no political stability, the economies are disarticulated, and their foreign exchange earnings depend on primary product exports". Use of the term "South" may also be country-relative, particularly in cases of noticeable economic or cultural divide. For example, the
