Name: _______________________________ CrashCourse: The Columbian Exchange Briefly explain how Christopher Columbus turned “world history” into actual world history: Green argues that Columbus, “irrevocably homogenized the world’s biological landscape.” Give 4 examples that support Green’s assertion: 4 categories of tangibles & intangibles on the Columbian Exchange & relevant info… #1 As a result of this exchange, estimates of death tolls in the Western Hemisphere reached as low as _______% and as high as _______% . Yikes. Now, identify biological elements exchanged across hemispheres: Bio Exchange – “New World” to “Old World” Bio Exchange – “Old World” to “New World” ___________ #2 Imports to the new world, especially animals, included the following: ____________ (Category) Significance in ∆ Environment ____________ #3 This new world tangible good was significantly more _________________than Old World food, meaning: _______________________________________________. ____________ This allowed the world population to _____________ between 1650 and 1850. #4 ____________ Explain how the previously identified 3 “things” in the Columbian Exchange correlated with this final (category name #4). Include in your response a reference to ‘homogeneity’ Name: _______________________________ Positives of Columbian Exchange over time Negatives of Columbian Ex. over time John Green ends with a keen synthesis of the Columbian Exchange and “modern globalism and monoculture.” Explain how these two developments in different historical periods (the former in the Early Modern Era and the latter in our own modern day) are inexorably linked: Some historians argue that “the Columbian Exchange has included man, and he has changed the old and new worlds sometimes inadvertently, sometime intentionally, often brutally. It is possible that he and the plants and animals that he brings with him have caused the extinction of more life forms in the last 400 years than the usual processes of evolution might kill off in a million… the Columbian Exchange has not left us with a richer but a more impoverished genetic pool. We, all of life on the planet, are the less for Columbus, and impovershment will increase.” Identify and explain ONE historical development that CHALLENGES this interpretation, and ONE historical development that SUPPORTS this interpretation.
