1. Climate and Human Activity
-Natural hazard occurrences (some caused by climate) can affect human activity and have significantly altered sizes and distributions of human populations in particular regions

2. Climate and Human Activity
-Changes in climate affect human activity (e.g., agriculture) and human populations, and that can drive mass migrations
-other examples: sea level, temperatures,
storms

3. Climate and Human Activity
-human populations depend on technological systems to acquire natural resources and to modify physical settings
-technology for survival: hunting, clothing
-technology used to predict: tsunamis,
hurricanes
-technology to visualize or prevent: fires
