Review Questions

• How does the geographical expanse of Eurasia contribute to its biodiversity?
  • The geographical expanse of Eurasia fosters biodiversity by encompassing various climates and ecosystems. From the Arctic tundra to temperate forests and arid deserts, these distinct environments support a wide range of flora and fauna. The connectivity between different habitats allows for species migration and adaptation, enhancing ecological diversity across the continent.
• In what ways has Eurasia's historical significance influenced cultural exchange and trade?
  • Eurasia's historical significance as a bridge between Europe and Asia has facilitated cultural exchange and trade through routes such as the Silk Road. This network allowed for the movement of goods, ideas, and technologies across vast distances, impacting societies on both sides. The resulting interactions have led to shared cultural practices, economic relationships, and advancements in various fields such as science, art, and philosophy.
• Evaluate the impact of climate change on the ecosystems found within Eurasia and discuss potential consequences for global biodiversity.
  • Climate change poses significant threats to the diverse ecosystems within Eurasia by altering habitats and affecting species survival. As temperatures rise, many organisms may struggle to adapt to new conditions or face habitat loss due to shifting ecosystems. The consequences could lead to decreased biodiversity as species go extinct or are forced to migrate. This decline in species richness within Eurasia could have cascading effects on global biodiversity since many species are interconnected through food webs and ecological functions.
