Why is the region of Eurasia home to 80 percent of humanity? (1 point)
The region of Eurasia is home to approximately 80 percent of humanity due to several factors:
1. Size and Diversity: Eurasia, which comprises both Europe and Asia, is the largest contiguous landmass on Earth. Its vast area provides a wide range of geographical and environmental conditions, allowing for diverse ecosystems and habitats. This diversity offers numerous opportunities for human settlement and development, accommodating a large population.
2. Historical Development: Eurasia has been a cradle of several ancient civilizations, such as Mesopotamia, Indus Valley, Egypt, China, Greece, Rome, and Persia. These civilizations contributed to the development of advanced agricultural practices, trade networks, and cultural exchanges, creating favorable conditions for sustained human settlements and population growth.
3. Agricultural Productivity: Eurasia possesses a diverse range of climatic zones, ranging from cold tundra to tropical rainforests. This diversity allowed for the domestication of a wide variety of plants and animals, leading to the development of advanced agricultural systems. This agricultural productivity supported larger populations and facilitated the growth and expansion of cities and civilizations.
4. Cultural and Technological Exchange: Eurasia has been a melting pot of various cultures and societies throughout history. Trade routes, such as the Silk Road, facilitated cultural and technological exchange between different regions of Eurasia, leading to the spread of ideas, innovations, and religious beliefs. This exchange further stimulated economic growth, social development, and population growth.
5. Access to Resources: Eurasia is rich in natural resources, including mineral deposits, fertile soils, freshwater sources, and diverse ecosystems. Access to these resources has provided favorable conditions for economic development, industrialization, and sustenance of large populations.
Overall, the combination of size, diversity, historical development, agricultural productivity, cultural exchange, and resource abundance has contributed to Eurasia's status as home to a significant majority of the world's population.
