Ecosystem Capital
sum of all goods & services provided by natural & managed ecosystems, provided free of charges & essential to human-life & well-being.
Manage & regulate while still using resources
ensure ecosystem continuity regardless of utility (protect from use)
to bring back to a former, original, biological diversity & ecological function (bring back to original state)
Maximum Sustainable Yield
Highest possible rate of use taht a system can match with its own rate of replacement.
Ecosystem services
sustain & fulfil life
Wilderness Area
most protected area, only 4% of land permanently protected.
Preservation not Conservation.
Parks & Wildlife Refuges
Protect Important wildlife & provide public access to recreation.
Difficult to balance public access & wildlife protection.
Matching energy sources to uses:
Crude oil
Transportation & industrial
Matching energy sources:
Natural Gas
Matching energy sources:
nuclear power
water & wood power
Electric (commercial & residential)
Primary Energy
fossil fuels, radioactive material, solar, wind, water & other energy sources that exist as natural resources subject to exploration (generate electricity)
Secondary Energy
source of energy (esp. electricity) depends on primary energy sources for origin.
Corporate Average Fuel Economy (CAFE)
Raise fuel efficiency regulations (27.5 mpg) key to greater oil independence
Combined Heat Technology (CHP)
small power plant that produces electricity & heats the building with "waste" heat.
Nuclear Fission
Splling of atomic nuclei
Nuclear Fusion
Fusing of atomic nuclei
Chain Reaction
(nuclear reaction) each atom that fissions causes one or more atoms to fission (liberates energy)
Renewable energy
energy from sources that are essentially inexhaustable (wood, waste, geothermal, wind, solar thermal energy)
Solar Radiation
Every location on earth recieves sun light, depends on:
Weather, location, landscape, time of day, season
Direct Solar Energy Use
heating of water
heating of space
production of energy
Indirect Solar Energy Use
Passive Solar Heating
building designs to capture suns' heat to provide space heating & light
Biomass Energy
plant material, vegetation, agricultural waste. Heating, electricity, or converted to liquid fuels
contamination of air, water, soil w/ undesirable amounts of material in environment.
Water Pollution
any biological, chemical, physical change in water quality that has harmful effect on living organisms or make water unsuitable for desired uses.
Point Source Pollution
specific points of origin of pollutants (factory drains, our outlets from sewage treatment plants)
NonPoint Source Pollution
soucres of pollution such as general runoff of sediments, fertilizer, pesticides from farms & urban areas
Oligotrophic Lakes
Nutrient Poor (Deep, transparent, low density of plant life)
Eutrophic lakes
Nutrient Rich & Shallow
enrichment of a lake ecosystem with chemical nutrients, typically compounds with N or Phosphourus
particulate organic matter that settles out or floats to the surface of sewage water in primary treatment
Liquid waste
Municipal Sold Waste
consists of everyday items such as product packaging, grass clippings, furniture, clothing, bottles, food scraps
Source Reduction
Reduse - consuming less & throwing away less
recovery of materials that would otherwise been incinerates or in landfills
natural reprocessing of organic matter - provides nutrients to soil
Integrated Waste Management
approach to municipal solid waste that provides for several options for dealing w/ wastes, including recycling, composting, waste reduction & landfilling & incineration where unavoidable
where weather occurs
contains ozone layer
Thermohaline Circulation
combo of temp. & salinity of ocean waters that causes water to circulate thru ocean
Ozone Shield
stratospheric ozone layer that absorbs UV radiation
Chloroflurocarbons (CFC's)
non-reactive, non-flammable, non-toxic, great properties of heating & cooling , reduce density of ozone layer
Air Pollution
particulate matter & chemical compounds that are released by humans into atmosphere & modify its composition
dense, visible air pollution
Primary Pollutant
released directly into air, such as CO2 from combustion
Secondary Pollutant
formed thru chemical reactions of primary pollutants
