Land & Water Use
Which method used by sustainable aquaculture operations helps prevent sea lice infestations that can impact wild fish populations?
Use non-native species selectively bred for growth rates.
High-density stocking levels.
Increased use of chemical pesticides.
Use of cleaner fish that eat parasites.
Which alternative energy source has minimal water usage during operation?
Hydropower facilities
Nuclear reactors
Geothermal plants
Photovoltaic solar panels
In meat production, which method is known for using less water compared to traditional irrigation techniques?
Sprinkler systems
Drip irrigation
Furrow irrigation
Flood irrigation
How might switching from conventional meat production methods to organic livestock raising influence local biodiversity?
Organic methods demand higher fossil fuel consumption, potentially displacing local species with habitat fragmentation caused by additional infrastructure needs
The transition typically involves intensified use of antibiotics, affecting nearby wildlife negatively
Organic livestock raising significantly amplifies genetic modification risks in surrounding ecosystems
Organic practices could enhance local biodiversity through reduced pesticide usage
What is a common consequence of overgrazing by livestock on grasslands?
Soil erosion due to vegetation loss.
Increase in carbon sequestration capabilities.
Formation of new habitats for native species.
Alleviation of invasive plant species growth.
How does the practice of concentrated animal feeding operations (CAFOs) conflict with sustainable water resource management?
They tend to be located away from watersheds minimizing their impact on local aquatic ecosystems.
They often produce large quantities of waste that can contaminate local water supplies if not managed properly.
They recycle animal waste as fertilizer thus reducing overall demand for freshwater resources.
They typically require less water per animal making them more sustainable than pasture-raised options.
Which method is most likely used in industrial meat production to promote rapid growth in livestock?
Antibiotic use
Organic farming
Integrated pest management (IPM)
Crop rotation

Factory farming
Which of the following is an environmental benefit of organic farming?
Reduced pesticide use and minimized water pollution
Increased reliance on synthetic fertilizers
Enhanced greenhouse gas emissions
Lower biodiversity in agricultural landscapes
Which policy change could most effectively reduce the carbon footprint associated with conventional meat production methods?
Encouraging increased production through vertical integration without emission controls.
Increasing subsidies for corn production used in animal feeds at large-scale operations.
Subsidizing alternative proteins to lower demand for meat from ruminant animals.
Mandating shorter transport distances for livestock but not altering feeding practices.
