Introduction to Sustainability
- sustainability - refers to humans living on Earth and their use of resources without depletion of the resources for future generations
- ecological footprint - the resource demand and waste production required for an individual or society
- sustainable yield - the amount of renewable resources that can be used without reducing available supply
Survivorship Curves
- Type I - (ex. gorillas)
- Type II - (ex. birds)
- Type III - (ex. mosquitoes)
- biotic potential - maximum reproduction rat under ideal conditions
- carrying capacity - maximum number of organisms and environment can support without resource depletion
Age Structure Diagrams
- pre-industrial - slow growth, high death rate, high birth rate
- transitional - rapid growth, advancement in medicine
- industrial - decrease in growth rate, women's rights, family planning
- post-industrial - negative or no growth
- exponential curve - J shape
- logistic curve - S shape
Demographic Transition
- demographic transition - refers to the transition of a country where it moves from a preindustrial to an industrial stage
- total fertility rate (TFR) - the number of births a woman has in her lifetime, many factors involved such as education, government policies, family planning, etc.
Human Population Dynamics
- doubling time - number of time for population to double
- rule of 70 - 70/ growth rate of population (%)
