A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon-per-minute showerheads. Each member of the family averages 8 minutes in the shower per day. In a 30-day period, how many fewer gallons of water will the family use with the new showerheads?
3,600
Which of the following is an environmental problem associated with abandoned coal mines?
Acid drainage due to leaching of spoil heaps by rainwater
Which of the following is a direct economic advantage associated with aquaculture?
Aquaculture produces large amounts of seafood for human purchase and consumption year-round.
Which of the following is a commercially used method for harvesting trees and is most likely to lead to a fragmented landscape with serious impacts on biodiversity?
Clear-cutting
Which of the following is an unintended environmental consequence of aquaculture?
Contamination of surrounding water by organic waste
1. Which of the following best illustrates the concept of the tragedy of the commons?
Depletion of an aquifer by regional farmers
2. Which of the following is the best illustration of the tragedy of the commons?
Depletion of fishing stocks in the North Atlantic
Which of the following changes to the local hydrologic cycle will result if large areas of land experienced clear-cutting?
Evaporation of water from the soil will increase.
Which of the following scenarios best explains the concept of the tragedy of the commons?
Fish are shared resources, and as the fishing industry competes for the fish, the resource extraction is no longer sustainable.
Which of the following describes an aspect of urbanization that would most increase the amount of carbon dioxide released into the atmosphere compared to rural and suburban areas?
Increased amounts of waste per unit area in urban areas that leads to higher rates of decay and decomposition
Which of the following best describes an environmental advantage of urbanization?
Individuals living in cities usually have a lower transportation carbon footprint than individuals living in rural areas.
Industrial logging threatens many forested ecosystems. Which of the following environmental consequences will most likely result from clear-cutting deciduous forests for logging?
More carbon dioxide will be added to the atmosphere and increase anthropogenic climate change.
Which of the following practices would have the biggest impact on achieving global sustainability?
Reducing human population size
Overuse of groundwater in coastal areas would most likely result in which of the following?
Saltwater intrusion
Which of the following best describes legislation that could be used to address problems with overfishing?
The Convention on International Trade in Endangered Species of Wild Fauna and Flora ( CITES ) uses trade rules to protect commercially valuable species.
Which of the following is most likely to occur in a forested region that has been recently clear-cut?
The concentration of nitrates in streams running through the region will increase.
Which of the following is the best example of an economic approach to reduce overfishing for a fish species with a declining population?
The federal government sets a catch limit (per person or per boat) for the species and imposes a tax on any extra fish that are caught.
Which of the following is a limitation of using only the data in the table to complete an ecological footprint analysis of the different students?
The footprint is a static analysis and does not include all environmental impacts of an individual.
Which of the following best describes the process known as "mountaintop removal"?
The use of heavy equipment to move overburden downhill during the strip mining of coal
Which of the following best explains why the maximum sustainable yield for ocean fisheries has been exceeded?
Too many fish of reproductive age are harvested.
Which of the following solutions would help decrease flood frequencies and flood sizes that are caused by urbanization?
Using new, more permeable materials for roads and sidewalks
3. Which of the following is the best example of the tragedy of the commons?
Water pollution from oil rigs concentrated in the Gulf of Mexico
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
Many communities experience the tragedy of the commons. One way a local community might regulate a shared and limited resource and reduce the tragedy of the commons is to
divide the resources into parcels and assign them to individuals
One way that consumers can help prevent a decrease in the number of fish species that are experiencing population declines is to
eat fish that are caught using sustainable harvesting methods, therefore ensuring fish populations remain stable and reducing the amount bycatch harvested
Salmon farming threatens the health of wild salmon stocks primarily because
farmed salmon can spread parasites and disease to wild salmon
As urbanization increases and natural soil surfaces are covered, the groundwater supply is reduced due to
loss of recharge area
he major cause for the decline in the worldwide catch of fish since 1990 is
overfishing
Environmentalists oppose the mining of antarctic mineral resources because
the antarctic environment is fragile and extremely vulnerable to the disturbances that would accompany development
The farming of fish such as salmon at aquaculture facilities poses a threat to marine ecosystems because
the farmed fish can escape and outcompete wild fish for food and territory
It has recently been estimated that the growth in world population has slowed in the past decade. Despite this trend, environmentalists remain concerned about the environmental impact of world population, principally because
the standard of living is increasing in many developing countries, leading to an increased per capita use of natural resources
Overgrazing of public land by privately owned livestock is an example of the
tragedy of the commons
A sustainable society would emphasize
using energy efficiently and reusing and recycling matter
