What is a drawback of Concentrated Animal Feeding Operations (CAFOs)?
Decreases cost for consumer
Increases efficiency and profitability for farmer
Increased Greenhouse Gases
Uses less land per head of livestock
What is one of the waste disposal issues associated with CAFOs?

Waste is disposed of in small, environmentally friendly compost heaps
Large housing systems regularly wash feces into small ponds
A single CAFO produces the amount of feces a town of 5000 would produce
What is a zoonotic disease?

A disease that spreads from animal to human
A disease that spreads from human to animal
A disease that affects only humans
What is the most common use of land in the U.S.?
Urban development
Conservation parks
Grazing of cattle
Crop farming
What is NOT a benefit of Free Range farming?
Ethically better
More holistic/natural
Higher use of antibiotics/hormones
Waste spread over a larger area, acting as fertilizer
Which diet has the lowest carbon footprint according to the text?
Meat lovers
Diet low in meat
Diet with high meat consumption
Diet with moderate meat consumption
What is a consequence of increased sedimentation in water bodies?
Higher aquatic NPP
Lower aquatic NPP
Increased oxygen levels
Decreased water usage
What is desertification?
The process of creating new deserts
The process of irrigating deserts
The degradation of low precipitation regions becoming increasingly arid
The conservation of desert ecosystems
What is the main idea behind Nomadic Regenerative Grazing?
Keeping herds in one place to improve soil quality
Moving herds to seasonally productive feeding grounds over long distances
Increasing the human population and demand for meat
Reducing the amount of land used for grazing
Which of the following accurately describes a benefit of concentrated animal feeding operations (CAFOs)?
Concentrated animal feeding operations produce a large amount of manure, which is then often held in large manure lagoons.
The animals raised in concentrated animal feeding operations are usually grass-fed and therefore less susceptible to disease.
Concentrated animal feeding operations are efficient and relatively low-cost facilities that help keep consumer costs low.
When animals are kept in large concentrations in a small area, the water quality of local waterways is protected from excess runoff.
The land on a 100-acre farm is equally suited for grazing cattle and growing corn. Of the following ways of distributing land use, which would produce the greatest number of calories of human consumption?
80 Acres for Grazing Cattle / 20 acres for Growing Corn
50 Acres for Grazing Cattle / 50 acres for Growing Corn
100 Acres for Grazing Cattle / 0 acres for Growing Corn
0 Acres for Grazing Cattle / 100 acres for Growing Corn
Corn can be grown at a rate of 1,000 kcal per hectare, and it takes 20 times more land to produce beef than it does to produce corn. Which of the following equations would correctly calculate the amount of land needed to produce 10,000 kcal of beef?
Compared with people in developing countries, people in industrialized countries are more likely to eat (a)
The development of dangerous strains of disease organisms represents a significant consequence of which of the following agricultural practices?
Using herbicides in mechanized, large-scale grain farming
Using plant-based insecticidal compounds on vegetable crops
Incorporating antibiotics into the feeding regimens of densely concentrated livestock
Growing crops that are genetically modified for increased yields
Vegetarianism is often cited as a partial solution to the growing problem of deforestation and other types of habitat destruction as the human population continues to grow. The reason for this is
vegetarians are healthier due to a lack of animal fat in their diets
more people can be fed using less agricultural land because vegetarians eat at a lower trophic level
vegetarians consume fewer calories per person and therefore require fewer acres of farmland
vegetarians often support conservation efforts that promote forest conservation
The presence of fecal coliform bacteria in a sample of river water suggests which of the following?
The pH of the river is very high.
The water is contaminated with animal waste.
The river is devoid of plant life.
The dissolved oxygen level of the river is high.
The presence of high levels of fecal coliform bacteria in a water source indicates that the water (a)
