Some are middle-income and moderately developed
Some are low-income

doubling time

Time it takes for a population to double given its growth rate
Use "Rule of 70"
Divide 70 by the growth rate to get the doubling time

resource

Anything obtained from the environment to meet our needs or wants; ex: air, coal, water, wood

perpetual resources

On a human time scale it is renewed continuously; ex: the sun

renewable resources

Can be renewed fairly rapidly (hours to several decades); ex: wood, water, air, fish

nonrenewable resources

Exist in a fixed quantity or stock in the earth's crust; ex: coal, iron, uranium

sustainable yield

Highest rate that a renewable resource can be used indefinitely without reducing its available supply

environmental degradation

Exceeding a resources natural replacement rate
Supply of resource shrinks

common property or free access resources

Commons
Individuals do not own the resource and the resource is available for all to use at little or no cost

Garrett Hardin

1915 - 2003
American Ecologist
Wrote paper titled, The Tragedy of the Commons

Tragedy of the Commons

Concept written about by Garrett Hardin
"If I do not use this resource, someone else will. The little bit I use or pollute is not enough to matter..."

ecological footprint

Amount of biologically productive land and water needed to supply an area with resources and to absorb the wastes and pollution produced by such resource use
How many Earths does it take to support your way of life???

per capita ecological footprint

per person ecological footprint; higher for developed countries and lower for developing countries

pollution

Presence of an unwanted material or substance in high enough levels in air, water, soil, or food to threaten the health, survival, or activities of a living organism
Natural sources and anthropogenic sources

point source pollution

Pollutants come from single, identifiable sources
Large amount coming from an area you can point to
ex: sewage effluent, smokestack emissions

non-point source pollution

Comes from larger dispersed areas and are difficult to identify
Ex: agricultural runoff, runoff from a housing development

pollution prevention or input pollution control

Reduces or eliminates the production of pollutants

pollution cleanup or output pollution control

Cleaning up or diluting pollutants after they have been produced

poverty

Inability to meet one's basic economic needs

malnutrition

10,000 years before European Settlers in early 1600's

frontier era

1607 - 1890
European colonists begin settling North America and using its resources

frontier environmental worldview

early conservation era

1832 - 1870
Some become alarmed at the resource depletion and degradation in the U.S.
Urged U.S. gov't to protect unspoiled lands owned by the public

environmental worldview

Your assumptions and values about how you think the world works and what your role in the world should be

environmental ethics

Your beliefs about what is right and wrong and how we treat the environment
