Production Methods
Define & Describe a CAFO
CAFO = concentrated animal feeding operation
Its when we grow a large amount of animals for animal products in a super small, confined area. This looks like cows inside a factory all touching one another
This term is used to describe a surface that does not allow water to pass through it.
Impervious surface
True or False: Most agriculture is used for direct human consumption.
False
Most agriculture is used for livestock
This is described as a concentrated area of minerals, makes it easy to mine
mineral deposit
ore
What is the KEY point about sustainability?
It emphasizes having enough resources for FUTURE GENERATIONS
What is a positive effect of CAFOs?
Lower production cost, lower consumer cost
This can happen to coastal cities such as Miami Beach & Atlantic City NJ.
saltwater intrusion
This is a pesticide specifically used to kill insects.
Insecticide
False, iron is a nonrenewable resource used to make steel
True
What is one way we could prevent overfishing?
Limits on number of fish we can catch
Don't catch females
Higher taxes on fish
How can we reduce the amount of pollutants in urban areas?
use more public transportation
use more electric transportation
Why should farmers be careful not to apply pesticides right before precipitation?
the pesticide will be easier to runoff with the water into our waterways and possibly cause eutrophication
This surface mining method is when you sift through river sediments, can use machines or hand to do this
placer mining
As a supply of a resource increases and becomes easier to access, what happens to the price?
(assume demand stays constant)
price decreases
What is a side effect of anitbiotic use in CAFOs
either antibiotic resistance
or
animals grow large in size in a short period of time.
How can we reduce the amount of water running off of urban areas?
reduce impervious surface
replace impervious with pervious
have rooftop rainwater collection systems
This can happen if pesticides are used too often and in an area of monoculture. This increases the risk for disease on the crop.
pesticide resistance
How can groundwater be contaminated near a mine?
acid leaching
This type of energy comes from sources like sunlight, wind, and flowing water and can be naturally replenished.
What is renewable energy
What is a common criticism the public has regarding CAFOs?
The ethics/morals of having animals inside and crammed together their whole life.
What are the 3 megacities in North/Central America?
New York, LA, Mexico City
How could scientists reduce the need for pesticides?
creating GMOs that are immune to certain bacteria we use the pesticides for that are now pesticide resistant.
Name 2 ways human health can be impacted by mining.
Lung damage from air pollution
Polluted water being ingested
mining accidents
vision or hearing problems from dust or large explosives
This concept describes the maximum population size of a species that an environment can support indefinitely without degrading natural resources.
What is carrying capacity.
