  • The objective for this unit is to set the stage for understanding how humans have altered the trajectory of Earths abiotic and biotic systems. Specifically this unit will dive into the history of humans on this Earth, how we became successful, how we utilize/acquire basic necessities (water, food), and the how increasing population densities have influenced environmental health. This unit will also addresses the past and present of how the above variables changed as our population changed.
