APES 5.7 Meat production methods

James, Scarlett, and Elijah are discussing the two main methods of meat production they learned in their agriculture class. What are the two methods they are talking about?

• CAFO and free-range grazing

• Feed Lots and rotational grazing

• CAFO and rotational grazing

• Feed Lots and free-range grazing

Benjamin and Lily are discussing the benefits of CAFOs in terms of meat production. Rohan joins the conversation and mentions one benefit. What is the benefit Rohan mentioned?

• Low cost of meat to the consumer

• No need for antibiotics or growth hormones

• Less impact on air and water quality

• Decreased topsoil erosion

During a field trip, Daniel, Michael, and Rohan came across a large open pit on a farm. Their teacher explained that it was a manure lagoon. Why could this be a problem?

• Large open pits where animal waste is stored, can contaminate water

• Areas of land where animals are allowed to graze, leading to over grazing

• Pools dug into the ground where animals are fed, causing compaction of soil

• Areas where animals are concentrated, resulting in loss of vegetation

Aria, Olivia, and Maya are studying the environmental impact of manure lagoons. They want to know the potential pollutants found in these lagoons. What are the potential pollutants they should consider?

• Ammonia, hormones, antibiotics, fecal coliform bacteria

• Carbon dioxide, methane, nitrous oxide

• E. coli, nitrogen, growth hormones

• Fertilizer pellets, surface waters, groundwater sources

Maya and Hannah are discussing the benefits of free-range grazing for their farm animals. What is one of the benefits they might consider?

• Animals can grow at a natural rate without antibiotics

• Low cost of meat to the consumer

• Decreased impact on air and water quality

• Increased topsoil erosion and desertification

Charlotte and Benjamin are discussing the drawbacks of free-range grazing in their agriculture class. What is the main drawback they mention?

• Requires more land and decreases efficiency

• Contamination of water and production of greenhouse gases

• Over grazing and compaction of soil

• Loss of vegetation and release of pollutants

Noah, Benjamin, and Evelyn are discussing the effects of overgrazing in their local park. What is overgrazing and why is it a problem?

• When there are too many animals grazing on a single area, leading to increased topsoil erosion

• Large open pits where animal waste is stored, contaminating water

• Areas of land where animals are allowed to graze, resulting in loss of vegetation

• Pools dug into the ground where animals are fed, causing compaction of soil

Aiden, Ethan, and Noah are working on a project to find a solution to overgrazing in their local community. What solution can they propose to address this issue?

• Rotational grazing

• Manure lagoons

• Feed Lots

• Free-range grazing

Olivia, Avery, and Abigail are discussing the environmental impact of food production. Why do they think producing meat is less efficient than producing plants for human consumption?

• Energy, land, and water consumption

• Contamination of water and production of greenhouse gases

• Increased topsoil erosion and desertification

• Loss of vegetation and release of pollutants

Ethan, James, and Samuel are discussing the energy inputs required for meat production in their environmental science class. What are the main energy inputs they should consider?

• Growing plants, bringing water, housing animals, and processing meat

• Contamination of water, production of greenhouse gases

• Increased topsoil erosion, desertification

• Over grazing, compaction of soil
