Why is the region of Eurasia home to 80% of humanity?
Temperature climate increase the likelihood of disease
Temperature climate support agriculture
Temperature climates are inhospitable for humans in
Temperature climate allow for easier defense against invading enemies
There are several factors that contribute to why the region of Eurasia is home to 80% of humanity:
1. Temperature climate support agriculture: Eurasia has a diverse range of climates, including temperate, Mediterranean, and continental climates. These varied climates provide favorable conditions for agriculture, allowing for the cultivation of a wide variety of crops. Agriculture has historically been a primary source of sustenance and economic activity, leading to the establishment of settled civilizations and the growth of populations in the region.
2. Temperature climates are inhospitable for humans: While some areas in Eurasia have more hospitable climates, many parts are characterized by challenging and harsh environmental conditions. Extreme cold temperatures, arid deserts, high-altitude regions, and other inhospitable terrains limit human settlement. As a result, populations are concentrated in more habitable areas, leading to high population densities in those regions.
3. Temperature climate increase the likelihood of disease: The presence of certain diseases and pathogens is influenced by climatic conditions. In some cases, temperate climates may facilitate the spread of diseases, as they provide a suitable environment for disease-carrying vectors like mosquitoes and ticks. Consequently, populations in Eurasia have faced the challenges posed by various infectious diseases, leading to the development of immunity over time. This, in turn, could contribute to higher population densities in the region.
4. Temperature climate allows for easier defense against invading enemies: Eurasia's vast landmass is characterized by a diverse range of geographical features such as mountains, rivers, and steppes. These natural barriers can provide strategic advantages for defense against invading forces. The region's history has seen the rise and fall of numerous empires, with the availability of natural defenses playing a significant role in shaping the geopolitical landscape. The ability to defend oneself more easily against invasions could contribute to the stability and sustained growth of populations in Eurasia.
It is important to note that these factors are just some of the reasons behind Eurasia's high population concentration, and there may be other contributing factors as well.
What’s the correct answer
The correct answer is a combination of the factors mentioned above. There is no one single factor that solely explains why the region of Eurasia is home to 80% of humanity. Rather, the interplay of favorable agricultural conditions, challenging environments, disease dynamics, and strategic advantages for defense all contribute to the high population concentration in Eurasia.
The region of Eurasia is home to 80% of humanity primarily because of a combination of factors, including favorable climatic conditions, historical developments, and geographical advantages. One important factor is the temperate climate in Eurasia.
Firstly, temperate climates in Eurasia are beneficial for agriculture. These regions experience distinct seasons with moderate temperatures, providing suitable conditions for cultivating a wide variety of crops. This agricultural productivity has historically supported larger populations, as it ensures a stable food supply for communities.
Secondly, temperate climates also play a role in disease prevalence. In regions with warmer and more tropical climates, certain diseases thrive and spread more easily. However, in temperate climates, the occurrence and transmission of certain infectious diseases, particularly those carried by insects, are reduced. This, in turn, contributes to higher survival rates and population growth.
Additionally, temperate regions often provide a more comfortable environment for human habitation compared to extreme climates. Extremely hot or cold environments can be challenging for human settlement due to the increased need for resources like shelter, heating, or cooling. In these inhospitable climates, it becomes more difficult to establish and sustain large populations.
Lastly, the geographical advantages of Eurasia, such as its vast landmass, natural barriers, and relative isolation, have also played a role in the concentration of human populations. Eurasia has varied topography including mountains, rivers, and deserts, which can act as natural defenses against invading enemies. The presence of easily defensible terrain has historically allowed civilizations in Eurasia to protect themselves more effectively, leading to greater population stability and growth.
In summary, the combination of favorable temperate climates for agriculture, reduced disease prevalence, more comfortable living conditions, and geographical advantages have contributed to Eurasia becoming home to 80% of humanity.
