Question 1

Which of the following statements best summarizes the SeafoodPrint research discussed in your text?

·         Through catch and release methods, researchers determined that second order fish are in danger due to overfishing.  

·         By monitoring eating habits, researchers found that rich nations underestimated their impacts on fish populations, which could in turn threaten the future of certain species.  

·         By tagging apex species, researchers determined there is no immediate danger to large fish populations within our oceans. 

·         Utilizing GPS tracking techniques, researchers suggest planned conservation efforts that surround fish migration patterns. 

·         None of the above statements summarize the SeafoodPrint research.

Question 2

·         True  

·         False

Question 3

Which of the following is an environmental concern of genetically engineered crops mentioned in your text?

·         Genetically modified crops lead to larger applications of toxic herbicides and insecticides.  

·         The genetic modification of crops increases soil erosion while decreasing soil fertility.  

·         Genetic engineering is less precise than traditional methods of crossbreeding.  

·         Genes from genetically modified crops may transfer to non-genetically modified crops.  

·         All of the above are environmental concerns of genetically engineered crops.

Question 4

Which of the following is not an environmental impact of conventional agriculture expressed in your text?

·         Agricultural practices improve wildlife habitats and lead to increased species populations in farming communities.  

·         Agricultural practices can lead to significant air quality concerns through the emission of ammonia, nitrous oxide, methane, and other potentially dangerous gases.  

·         Poor soil management can lead to biological, chemical, and physical degradation, which can in turn negatively alter the activity of soil fauna.  

·         Major agricultural pollutants such as pesticides can enter surface water and pose serious risks to human health.  

·         All of the above are environmental impacts of conventional agriculture.

Question 5

What is the central theme of “The case of Albuquerque” section in Chapter 5.4 of your text?

·         In the face of a major water crisis, a number of governmental initiatives, including altered water-use codes, rebates, and decreased water use to more sustainable levels.  

·         As the population of Albuquerque continues to grow, increased revenue from taxes will be able to solve the city’s water crisis.  

·         The impending water crisis in Albuquerque was solved through the desalination of brackish water from a nearby canal.  

·         Currently, Albuquerque is faced with a major water crisis that has no evident solution.  

·         None of the above are the central theme.

Question 6

What statement best summarizes the approach being used to clean up the Jordan River discussed throughout Chapter 5.5 of your text?

·         Teams of governmental officials are utilizing specialized filtration techniques to clean the polluted water and restore the river.  

·         Nonprofit groups are working to educate river communities about the value of the river and persuade national leaders to adopt measures that will revitalize the area.  

·         Citizen groups from multiple countries are working together to remove debris from the river and propose a ban on local pollutants.  

·         An international ban on agricultural development within one mile of the river is being proposed as a means of reducing runoff pollution in the region.  

·         None of the above are approaches being utilized.

Question 7

Which of the following statements summarizes the water situation in China that was discussed in your text?

·         China has been able to avoid major water shortages due to its construction of the Three Gorges Dam, which provides electricity and agricultural water throughout China.

·         Due to the water-rich Yangtze River Basin, China has been able to provide clean water to much of the highly populated region, even in the face of growing population.

·         Due to its large population, China is experiencing water shortages that have significantly decreased numerous wildlife populations.  

·         In the face of a growing population, China has begun to use desalination techniques to provide ample clean water to its people and agricultural soils.  

·         All of the statements about water in China are true.

Question 8

A decrease in “food miles” will most likely increase the environmental impact of any given food.  

·         True  

·         False

Question 9

Which of the following statements about ground water is not true, according to your text?

·         Underground aquifers hold approximately 99% of all the liquid fresh water.  

·         More than 75% of underground water has a replenishment time of centuries or more, making it non-renewable.  

·         Increased water withdrawal from underground aquifers makes them more susceptible to droughts.  

·         Depletion of ground water may lead to land compaction that in turn decreases its ability to store water. 

·         All of the statements about ground water are true.

Question 10

What is the central theme of “The first green revolution” section in Chapter 3.1 of your text?

·         The green revolution resulted in increased crop production without any environmental concerns, which generated a steep incline in human population growth.

·         The green revolution allowed for a rapid increase in high yield crops through the use of genetically modified seeds that allowed developing nations to survive in the face of famine.

·         The green revolution led to increases in crop production and human population. However, it also created a number of environmental concerns including the overuse of fertilizers and irrigation.

·         The green revolution allowed farmers to increase crop yields and profits substantially over a short period of time.

None of the above are the central theme.
