U5L3 Meat/Fish/Mining Lesson SelfCheck

Multiple Choice

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.

Multiple Choice

What is a disadvantage of CAFOs?

• Maximizes land use and profit

• Minimizes cost of meat for consumers

• Produces large amounts of greenhouse gases

• Prevents disease outbreak

Multiple Choice

What are the potential environmental impacts of manure lagoons as described in the image?

• Contamination of water sources

• Increased soil fertility

• Reduction of greenhouse gases

• Improvement of air quality

Multiple Select

What are the disadvantages of free range grazing? (Multiple Answers)

• More expensive to consumers.

• Doesn’t require production of corn

• Waste is dispersed over land naturally

• Requires more total land use/pound of meat produced

Fill in the Blank

______factors contribute to the inefficiency of meat production compared to plant production.

Open Ended

Explain an environmental benefit of eating a plant-based diet, rather than a meat-based diet, using the data below.

Multiple Choice

Overfishing is causing the decline of fish populations, such as Eastern Atlantic bluefin tuna in the Mediterranean. Eastern Atlantic bluefin tuna are caught faster than they can reproduce. Which statement describes the most likely effect that overfishing will have on this ecosystem?

• Overfishing makes the ecosystem more stable by increasing competition for limited resources.

• Overfishing decreases the stability of the ecosystem by disrupting food chains.

• Overfishing has no effect on ecosystem's stability because it affects on species out of many.

• Overfishing increases ecosystem stability by allowing prey populations to overproduce.

Multiple Select

What are the economic consequences of fishery collapse? (multiple answers)

• Increased tourism

• Lost income for fishermen

• Loss of biodiversity in ocean ecosystems.

• More fish species

Multiple Select

How does the previous lesson the Tragedy of the Commons relate to the economic impact did overfishing from 1975 to 1985 have on profits from 1985 to 2018? (select multiple answers)

• Lack or regulation lead to abuse of resources.

• Sharp loss of profits following overfishing.

• Massive fishing led to an economic boom in the fishing industry that continues to today.

• Incentives were created that prevented economic loss from overfishing.

Multiple Choice

What are the negative impacts of bottom trawling on marine life and coral reefs?

• Increases biodiversity

• Destroys coral reef structure

• Reduces ocean sediment

• Enhances fish populations

Multiple Choice

What happens to marine mammals and seabirds as we deplete larger predatory fisheries?

• They thrive due to increased food supply

• They migrate to other regions

• They face food shortages

• They become more abundant

Open Ended

Propose a solution to address the issue of fishery depletion.
