1. HUMAN POPULATION GROWTHpp

2. Exponential model of growth

3. HISTORY Hunter-gatherer lifestyle 500 kya 10 kya
Development of Agriculture: increased and stabilized food supply
Population Explosion: decline in death rates

4. POPULATION GROWTH TODAY
Stastistics
Growing 1.5% annually

Improved healthcare (prenatal and geriatric)
Improved sanitation
Disease control
Education
