apes unit 5 practice

Which of the following is a direct economic consequence that would likely occur if an area of forest was clear-cut so that a housing development can be built?

A decrease in the number of game hunting licenses purchased

Which of the following is an example of an industrial practice that contributes to the tragedy of the commons?

Burning fossil fuels for energy production

The hog-farming industry maintains production levels to satisfy the demand for pork. Which of the following methods of meat production would provide the most likely explanation for the information represented in the graph above?

Concentrated animal feeding operations

Various nations have adopted policies designed to combat overfishing. Which of the following approaches is commonly used to combat the problem of overfishing?

Enforcing minimum-size requirements for the capture of some commercial species

Three common methods of beef production include using rangelands, pasture, and feedlots. The environmental impacts of these different methods for a variety of variables is compared in the graph below. Which of the following claims is best supported by the data in the graph?

Feedlots have high levels of pesticide use and energy consumption as a result high demands for grain production.

Aquaculture or fish farming can be used to increase the availability of species like salmon and shrimp for consumption. Although fish farming can have a number of negative environmental effects, it does offer a number of advantages. Which of the following is a valid reason for promoting the use of fish farms?

Fish production is constant, and fish farming reduces pressure on wild stocks.

Humans consume a variety of protein products, each with a different carbon footprint based on a variety of factors. Which of the following claims is best supported by the data in the graph?

Grass-fed beef has the highest carbon-equivalent footprint because of land-use changes to create pasture land combined with contributions from transportation, processing, manure treatment, making fertilizers, and digestive fermentation processes.

Which of the following is an unintended consequence associated with waterlogging caused by flood irrigation?

Higher water tables

Which of the following statements best summarizes the author's predictions for how humans will meet the future nutritional needs of a growing population using current agricultural technology?

Humans have maximized the crop yield with improving technology and the implementation of modern genetic techniques to further increase crop productivity and resilience in order to meet the demand.

Which of the following techniques could best reduce the harmful effects of overfishing if it were to be widely adopted by the fishing industry?

Increased use of large-mesh gill nets for harvesting salmon and trout

After intensive logging, most of the trees along a stream have been removed. Which of the following water quality changes would most likely occur downstream after logging?

Increased water temperature

Which of the following best exemplifies how an action within the fishing industry could lead to a tragedy of the commons?

Overfishing of threatened fish species leading to the eventual depletion of the resource

Which of the following would decrease with the manufacture, application, and use of synthetic fertilizers rather than organic fertilizers?

Recycling of organic matter

Which of the following best describes the concept of the tragedy of the commons?

Resources that are shared by individuals, such as the Ogallala Aquifer groundwater, are highly regulated by legislation, thereby depriving common people of their use.

Which of the following is an assumption made by the author regarding the use of genetically modified crops?

The amount of arable land will remain relatively constant, and the growing human population will have enough food if more crops can be harvested from the same amount of land.

The green revolution has improved global agricultural output. Which of the following best describes the author's perspective on the beginning of the green revolution in the 1970s and 1980s?

The green revolution was successful because of selective breeding, which improved nutritional value and crop yield to increase food production.

Which of the following describes an unintended consequence that results from large-scale agricultural use of water from an aquifer?

The rate of water use likely exceeds the rate of recharge, leading to lowering the water table.

Which of the following best describes environmental damage caused by slash-and-burn farming in tropical rain forests?

The soil loses fertility after a short period of time and will be ineffective for farming use.

Which of the following environmental effects would most likely result from the clear-cutting of boreal forests by industrial logging operations?

There will be an increase in atmospheric carbon dioxide concentration, which will contribute to climate change.

Which of the following best describes the advantages and disadvantages of drip irrigation?

This method most efficiently delivers water directly to plant roots compared with other methods, and wastes less water, but it may be too costly for farmers in developing countries to use.

Which of the following agricultural practices results in soil degradation and most contributes to erosion?

Tilling
