Biotic potential of a population
Amount population would grow if there was unlimited resources
Carrying capacity
Max pop size that is supported by available resources
Rule of 70
Divide 70 by the current growth rate to get doubling time
R vs k selected organisms
R- produce early and often
little attention given to offsprings
K- fewer offsprings
devote a lot of time to children
Current world population
7.3 billion people
Annual growth rate calculation

Growth states Pre- industrial Transitional Industrial Postindustrial
Pre- high birth and death rate
Transitional - high birth, low death. Rapid growth
Industrial- birthdate similar to death rate
Postindustrial- reach zero growth rate
Ecological foot print calculation
Impact= pop size X affluence X technology

Requires EPA to approve all pesticides in the us
Contour plowing
Terracing

Crop rotation
Contour- rows plowed on hillside to prevent erosion
Terracing- stairs in hillside
