Why is Mongolia called the dead heart of Asia?

The term "dead heart of Asia" is sometimes used to refer to the Gobi Desert, which covers parts of both Mongolia and China. The term is used to describe the harsh and inhospitable nature of the desert, which is characterized by extreme temperatures, limited water resources, and sparse vegetation. However, it is important to note that Mongolia encompasses diverse landscapes; not all regions within Mongolia or the greater part of central Asia, which includes regions in countries neighbouring Mongolia's western and Southern frontiers, can accurately be described as such.
