desertification
salinization
denitrification
Cattle release what type of greenhouse gas as a result of fermentation in their digestive tract?
Oxygen
Carbon Dioxide
Phosphorus
Methane
People in developed countries tend to eat more
corn
potatoes
meat
rice
Which of the following is an unintended environmental consequence of aquaculture?
Meeting an increasing demand for seafood
Decreasing the prevalence of disease in nearby wild fish
Contamination of surrounding water by organic waste
High initial cost of facility
Which methods of irrigation is the least efficient with the highest rate of evaporation?
furrow irrigation
spray irrigation
drip irrigation
flood irrigation
Overgrazing of grasslands can lead to reduced range quality. Two of the major effects of overgrazing are
erosion and desertification
eutrophication and increased methane production
higher primary productivity and ammonification
higher fire potential and increased productivity
Which of the following reduces the use exposures to toxic chemicals?
Crop dusting
No-till agriculture
Intercropping
IPM
The major cause for the decline in the worldwide catch of fish since 1990 is
escalating price of fuel
competition from aquaculture
overfishing
decline in market price
Which of the following is an example of a positive feedback loop?
Your brain saying you are hungry
A thermostat maintaining a certain temperature in your house
Exponential population growth
Pesticide resistance
Which of the following best illustrates the concept of the tragedy of the commons?
Selective harvesting of trees by a timber company in a national forest
Legislation of catch limits to avoid depletion of fish stocks in a shared lake
Inadvertent destruction of beneficial species while attempting to control pests
Depletion of an aquifer by regional farmers
A sustainable society would emphasize
A sustainable society would emphasize
converting the world’s high-quality energy resources to low-quality heat
recycling both matter and high-quality energy
using energy efficiently and reusing and recycling matter
Overuse of groundwater in coastal areas would most likely result in which of the following?
Rise in water table
Increase in stream flow
Bacterial contamination of surface water\
Saltwater intrusion
As urbanization increases and natural soil surfaces are covered, the groundwater supply is reduced due to
increased evaporation and transpiration
decreased surface runoff
loss of recharge area
confinement of aquifers
Sustainable use of forests in the United States would likely be encouraged by
cutting small groups of medium- and large- sized trees in uneven-aged forests
clear-cutting old-growth forests to allow for secondary succession
logging on steep slopes in designated wilderness areas
allowing road building in wilderness areas so that older, clear-cut forests have time to regenerate
