Book excerpt: Afro-Eurasia: Assessing Sustainability focuses on the geographic area where humans originated and first began to make use of the natural world - Earth's largest landmass, stretching from Portugal in the west across the steppes of Russia and south across Africa to the Cape of Good Hope. By examining the history of human expansion, as well as 21st century pressures to address ecosystem damage across the region, international scholars and regional experts weave sustainability into core curricular subjects. The interdisciplinary coverage includes national and regional environmental histories, as well as business and commerce, migration, educational institutions, law and government, and the lifestyles of diverse populations.
