Sustainable
To keep in existence, maintain
Hunter-Gatherer
• Nomadic• Small impact on environment- low population
density allows the environment to regenerate
Agricultural• Farming• Settled permanently• Plows• Domestication of
animals• Increase in food
supply leads to increase in population
Industrial
• Machines• Advanced technology• Factories• Increase in population• Increase in pollution
Sustainable Development Ethic
• Resources are limited• Humans are part of nature
Renewable resource
• A source that regenerates quickly• Ex: water, wind, sun, geothermal
Nonrenewable resource
• A resource that cannot regenerate quickly- will run out
• Fossil fuels- coal, oil, gas
Birth rate
The number of babies born in a year
Death rateThe number of deaths in a year
Malthus
• Population is increasing faster than food supply
• Reduce population by later marriages, smaller families
Germ Theory
• Bacteria and other microorganisms responsible for disease
• Sterile surgery, better personal hygiene, water treatment
Biomedical Revolution
• Increase in vaccines and antibiotics• Led to an increase in population
Exponential Growth
• Growth rate increases more each year
• Ex: human population
Doubling time
The amount of time it takes the population to double
Immigration
• People moving into an area• Increases the growth rate
Emigration
• People leaving an area• Decreases growth rate
Demography• The number and types of people that make up
a population• Can help determine how the population is

Endemic• A disease that is normally present in a certain
geographic area• Ex: Malaria is endemic to Africa
Fossil Fuel
• Fuels from the remains of organisms that lived long ago (fossils)
• Ex: coal, oil, gas
Coal
• Solid• Result of decaying plants, sedimentation, heat
and pressure
Petroleum
• Liquid• Formed from aquatic microorganisms,
sedimentation, heat and pressure
Natural Gas
Formed from aquatic microorganisms, sedimentation, heat and pressure (same as
petroleum)
Fracking
Fracturing shale rock with a pressurized fluid to release petroleum or natural gas
Shale Rock
Non-porous rock where
natural gas is trapped
