AP Environmental Science: Unit 5 Exam |
Accurate Q’s and A’s
The Tragedy of the Commons - -The tendency of a shared, limited resource to become
depleted as people act from self-interest for short-term gain from overuse.
-How fisheries can be susceptible to the tragedy of the commons - -The different fish
among different ecological regions have led to competition for fish among nations without
restrictions or replenishment.
-Externalities - -A cost or benefit of a good or service that is not included in the purchased
price of the food or service.
-Maximum Sustainable Yield - -The maximum amount that can be harvested from a
resource without compromising the future availability of that resource. Can be be found
halfway to carrying capacity on a growth diagram (logistic growth as s-shaped). Will insure
a future population of a resource (food), but also leave enough for safe competition.
-BLM Lands (Bureau of Land Management) - -Grazing, mining, timber, recreation.
-USFS Lands (United States Forest Service) - -Timber harvesting, grazing, and recreation.
-NPS Lands (National Parks Service) - -Recreation and conservation.
-FWS Lands (Fish & Wildlife Services) - -Wildlife conservation, hunting, and recreation.
-The Taylor Grazing Act of 1934 - -Regulated overgrazing by converting to a permit
system to limit the number of animals overgrazing. Is said to have been backed by BLM in
order to promote grazing.
-Clear-Cutting - -Removing all or almost all the trees within an area and is the easiest and
most economical method. May reduce biodiversity and can cause wind and water erosion
on slopes.
-Selective Cutting - -Removes single or small numbers of trees in a given area. Allows for
reseeding and younger trees planted but can only specifically target shade-tolerant species.
-NEPA (National Environmental Policy Act) - -Mandated an environmental assessment of
all projects involving federal money or federal permits.
-Environmental Impact Statement (EIS) - -A statement that outlines the scope and
purpose of an architectural project, its environmental context, and environmental impacts
or alternatives.
