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

changing

Standard of Living

The level of wealth and resources available in an area

Pathogen

• A diseasing causing organism• Ex: bacteria, virus, fungus, parasite

Influenza 1918• Pandemic• Flu virus• Killed 30 million people worldwide

A sharp increase in the incidence of a particular disease in a localized area

Pandemic• A sharp increase in the incidence of a disease

in a large geographical area• Ex: Influenza of 1918 (Spanish Flu)

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
