Subject One:Green ArchitectureSubject One:Green Architecture
Lewis Center for Environmental Studies, Oberlin College
Ways the building is environmentally friendly:
motion sensors for lights, waste water recycled for toilet use, triple pane windows

Ways the building is environmentally friendly:
motion sensors for lights, waste water recycled for toilet use, triple pane windows
DEFINITION: DEFINITION: describes environmentally-conscious design techniques in the field of
architecture. Sustainable architecture is framed by the larger discussion of sustainability and the
pressing economic and political issues of our world.
Subject Two:ENVIRONMENTAL SCIENCESubject Two:ENVIRONMENTAL SCIENCE
Environmental Science
DEFINITION: interdisciplinary study of humanity’s relationship with other organisms and the nonliving physical environment
POLLUTION= any alteration of air, water, or soil that harms the health, survival or activities of living organisms
What do we need? / What’s cheapest? POLLUTION PREVENTION

One goal of environmental science is to use ECOLOGY to address human population growth
ECOLOGY= discipline of biology that studies the interrelationships between organisms and their environments
ENVIRONMENTAL SUSTAINABILITY
Earth’s natural capital..
renewable=LIVING, replenishable=NONLIVING

WHY aren’t we sustainable?WHY aren’t we sustainable?we’re using non-renewable resources as if they’re we’re using non-renewable resources as if they’re

Challenge= meet immediate needs AND protect Challenge= meet immediate needs AND protect the environment in the long term. the environment in the long term.
Subject Three:EVOLUTION OF PEOPLESubject Three:EVOLUTION OF PEOPLE
EVOLUTION OF PEOPLE
a. Hunter Gatherers- used “earth wisdom”, had only three energy sources (sun, fire, muscle power), attempted to live sustainably
b. Agricultural Revolution- began 10,000-12,000 years ago, gradually settled into communities, urbanization, farming, large families, domesticated animals, birth rates up, accumulating material goods, survival of plants and animals became less important. focused on farming/managing nature

c. Industrial Revolution- began around 1870s, production, commerce, trade, shifted dependence from renewable to non-renewable resources, new machines, BIGGERBIGGERBIGGER
d. Technological Revolution- new technologies are enabling people to deal with more information more rapidly, impact is not yet clear.

Subject Three: MEETING THE CHALLENGESubject Three: MEETING THE CHALLENGE
2002 World Summit2002 World Summit
1992- UN Conference on Environment and Development
Focused on: pollution, deterioration of atmosphere and ocean, decline in species diversity, deforestation
AGENDA 21-
recommended over 2500 actions to deal with the most urgent problems
2002- World Summit on Sustainable Development
assessed progress/failures
agreements don’t help unless ENFORCED

Subject Five: OUR IMPACT Subject Five: OUR IMPACT
a. Increasing human population
poverty... World Bank estimates 2.8 billion live in EXTREME poverty
b. Population, Consumption, and Environment Impact
Impact on the environment can be calculated with I=PAT
I- environmental impact
P- # of people
A- affluence per person (amount of resource used)
T- environmental effects of technologies used

SY may be calculated as the rate of increase in natural capital
two ways of looking at it...
a. SY= (TOTAL BIOMASS at a time t+1)- (TOTAL BIOMASS at a time t)
b. SY= (annual growth and recruitment)-(annual death and emigration)

Subject Six: The Role of ETHICS, VALUES, and WORLDVIEWS in Addressing Environmental Problems
ETHICSETHICS
definition= branch of philosophy that is derived through the logical application of human values
values= principles that an individual or society considers important or worthwhile
can change as society changes
environmental ethics= applied ethics considering the moral basis of environmental responsibility and how far it extends
