Ch 8.3 Flashcards
T/F- As income increases, so does the consumption of meat
True
T/F- Generally more money equals better diets and better health (affluence)
True
T/F- Consumption of animal products decreases with wealth
False, increases
T/F- On average, Americans consume 225 pounds of meat per person per year
True
T/F- the recommended amount of protein ,50 grams a day, equals about 40 pounds of protein per year
True
Obesity and associated diseases increased in countries where meat consumption has increased is known as
Affluence
a situation in which meat or dairy animals are raised in confined spaces, maximizing the number of animals that can be reared in a small area is known as
Concentrated animal feeding operation (CAFO)
T/F- The methods used to rear animals, especially industrial methods such as CAFOs, raise environmental concerns such as deforestation, biodiversity loss, water and air pollution, and climate change; rearing large numbers of animals in close quarters raises ethical concerns.
True
What are some of the many issues concerning meat production?
- Lack of sustainability
- Negative impacts on human health
- Worldwide habitat destruction
- Air and water pollution
- Facilitation of climate change
- Overuse of antibiotics and the evolution of drug-resistant bacteria
What is one of the major problems associated with CAFOs specifically related to what it does with manure?
Advantage- some is used as fertilizer
Consequence- if it is not used as fertilizer the rest may be stored in lagoons or other water sources
Pig farm in North Carolina, where in 1994 the lagoons collapsed. What happened to the river where the infected water was stored?
Water went into New River, killing 10 million fish, closing shellfish areas, and producing a big stench.
the amount of CO2 (and other greenhouse gases that contribute to climate change) released to the atmosphere by a person, company, nation, or activity is known as the
Carbon Footprint
T/F- CAFOS have very large carbon footprints- about 14.5% of global greenhouse gas emissions
True
GO BACK TO SLIDE 12
the amount of edible food that is produced per unit of feed input this is known as
Feed conversion ratio
What measures how quickly and efficiently any given animal converts the food it eats into body mass. ( Higher the number, the less efficient)
Feed conversion ratio
T/F- About 75% of all US cropland is used to grow food for livestock
True
The amount of water consumed by a given group (that is person or population) or for a process (such as raising livestock) is known a
Water Footprint
For meat production, what are the two primary water uses?
growing the feed
handling the vast quantity of manure that is produced
Memorize chart on slide 16,17
T/F- Rearing animals, such as cattle, on pasture imposes a
lower environmental burden than CAFOs, but the meat and dairy produced this way will likely cost more due to the loss of efficiencies of scale that CAFOs offer
True
This type of farm rear different species of animals )or a mix of animals and plant crops) together, typically in some sort of rotation this farm is known as
Polyculture farms
What type of farms fits the following characteristics
Animals are raised on pasture farms
for their whole lives.
* Animals are healthier because they
eat a more natural diet of grass and
spend more time moving around.
* Meat and milk are healthier.
* This type of farm addresses many of
the ecological problems associated
with feedlots.
Sustainable Farms
The legislation that deals with many aspects of the production and sale of farm-raised commodity crops is called
U.S. Farm Bill
