Why are cows fed corn in CAFOs?
It is cheap and accelerates growth
It prevents bacterial growth
It is easily dried and stored
Cows digest corn easily
Cows in CAFOs require more antibiotics because
they eat corn and stand in their own wastes
they are densely packed
the breed of cattle used in CAFOs tend to be weaker
they are older than grass fed beef
CAFOs make meat more economical, but may have some negative environmental impacts. These include all of the following EXCEPT
increase in nutrients in stormwater runoff.
increase in sediments in stormwater runoff.
increased use of land area over other types of animal farming.
high concentrations of animal waste.
Overgrazing of grasslands can lead to reduced range quality. Two of the major effects of overgrazing are
erosion and desertification
eutrophication and increased methane production
higher fire potential and increased productivity
higher primary productivity and ammonification
Compared with people in developing countries, people in industrialized countries are more likely to eat…
Beef
Corn
Rice
Beans

The chickens are made bigger and slaughtered later.
The chickens are made smaller and slaughtered later.
The chickens are made bigger and slaughtered sooner.
__________________________ of a fishery is the highest amount of species that can be harvested without diminishing the populating in future years.
Maximum Sustainable Yield
Exclusive Economic zone

What is aquaculture?
The study of saltwater and freshwater organisms for use in medicine
The breeding of land plants and animals to be used as fish feed
The breeding, raising and harvesting of both fresh and saltwater organisms
The manufacturing of aquatic organisms into feed and fertilizer
Which of these is NOT an environmental concern of farming fish?
Introducing pesticides, herbicides and antibiotics into the environment
Transferring disease from farmed fish to wild fish and vica versa
Increasing waste in slow moving water
Potentially introducing native fish into the wild
Measure of how much a person/group consumes, expressed in area of land
Ecological Footprint
Ecological Factor
Carbon Footprint
Waste Footprint
Which of the following is NOT something that would DECREASE your footprint
Renewable energy use (wind, solar, hydroelectric)
Less consumption, less travel, less energy use
Larger houses
Plant-based diet
Which of these problems could happen if we don't look after the resources we have?
Loss of animal homes
Climate change
Increase in pollution
All of the above
IPM is likely to use all of the following techniques EXCEPT
intercropping.
habitat creation for pest predators.
planting herbicide-resistant crops.
increased use of traditional pesticides.
Which of these best describes a practice that aligns with integrated pest management?
increasing fertilizer use to improve crop yield per hectare
introducing natural predators of a pest species to decrease their crop damage
using pesticides earlier in the season to increase their effectiveness
growing monocultures so that crops will be easier to manage
Which statement best describes sustainable use?
Balancing use and conservation.
Not using resources in order to conserve them.
Creating more resources in order to conserve others.
Using resources as they are needed regardless of availability.
True or False? When IPM is implemented, the need for chemical pesticides is eliminated.
True
False
IPM is likely to use all of the following techniques EXCEPT
intercropping.
habitat creation for pest predators.
planting herbicide-resistant crops.
increased use of traditional pesticides.
Which of the following strategies would help ensure that we can provide food for a growing human population?
Increase ethanol production in industrialized nations
encourage parents to have more offspring to increase available farm labor
increase palm oil production in poor countries
reduce the amount of meat consumption worldwide
Use of this method of control requires concentrations to be increased often because pest develop resistance
GMOs
Pestsides
plant removal
control burning
