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 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 would be the best solution to the pest problem
Use of integrated pest management
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?
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?
Many communities experience the tragedy of the commons.
divide the resources into parcels and assign them
Which of the following scenarios best explains the concept of the tragedy of the commons?
fish are shared resources
What is an environmental advantage for urbanization
individuals living in the city have lower carbon footprint than rural areas
Which of the following is the best example of an economical approach to reducing overfishing for a fish species with a declining population?
the federal government to have a catch limit
Which of the following statements best describes the most unsustainable method of clear-cutting forests to harvest timber?
the most unsustainable method of clear cutting forests to harvest limber is cutting them all in one operation
Which of the following is the most likely result from clearing mature, forested land and converting it into agricultural land that would be used for cattle grazing?
there will be a reduction in the uptake of atmospheric carbon dioxide
Which of the following agricultural practices results in soil degradation and most contributes to erosion? Responses Tilling Tilling Crop rotation Crop rotation Intercropping Intercropping Terracing
tilling
One example of the tragedy of the commons occurs when trees are harvested from tropical rain forests without any regulations. Which of the following best describes why this is an example of the tragedy of the commons?
timber producers remove as much timber as much as possible
The data in the table show mean concentrations (mg/L)(mg/L) of pollutants in rainwater leaving either green or conventional roofs. Which of the following data would be needed to calculate the total amount of a pollutant leaving the roof during and following a rainstorm?
total volume of rainfall
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
Which of the following best describes legislation that could be used to address problems with overfishing?
CITES
Which of the following is an unintended environmental consequence of aquaculture?
Contamination in the seafood from organic waste
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 methods
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.
Which of the following irrigation methods is most likely to result in salinization of the soil, especially if the agricultural fields are located in a warm climate with consistent sunlight?
Furrow irrigation
Humans consume a variety of protein products, each with a different carbon footprint based on a variety of factors.
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 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 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.
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.
In a rural region of India, scientists collected data of different pesticide residue levels from closely located farming plots. Some of these plots used integrated pest management biopesticides, while others used chemical pesticides to control pests. The data below show levels of four pesticide residues found in tomato and cucumber crops in the two treatment plots.
Tomato and Cucumbers
Which of the following is a direct economic advantage associated with aquaculture?
agriculture provides a large amount of seafood per year
Which of the following changes to the local hydrologic cycle will result if large areas of land experienced clear-cutting?
if large areas of land experience clear cutting, the evaporation of water from soil will increase
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 into the atmosphere and increase in athropgenic climate change will result from clear cutting forests for logging
help decrease flood frequencies and flood sizes that are caused by urbanization?
new permeable materials for roads and sidewalks
Methods farmers choose to reduce the cost
planting genetically modified crops
Farmers need to make many decisions about how they grow their crops. One of these decisions is whether to use synthetic fertilizer or organic fertilizer, such as manure. An advantage of using synthetic fertilizer instead of organic fertilizer is that
synthetic fertilizer provides more macronutrients to the crops
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
