What does the 'Tragedy of the Commons' refer to?

A historical event where common land was mismanaged.

The economic theory that individuals acting in self-interest will deplete a common resource.

A play by William Shakespeare.

Common tragic themes found in literature.

1

Which resource is often cited as an example of the 'Tragedy of the Commons'?

National parks

The Internet

Fisheries

Solar energy

1

What is an environmental issue most directly associated with clearcutting?

Enhanced greenhouse gas absorption

Increased soil erosion and sedimentation

Improved soil fertility

Increased water retention

1

How does clearcutting contribute to climate change?

Reducing trees that store CO2

Increasing the ozone hole

Releasing oxygen when trees are cut

Increasing the number of trees growing

1

What was a primary objective of the Green Revolution?

Reduce the environmental impact of farming

Promote organic farming methods

Increase food production through new agricultural practices

Decrease reliance on synthetic chemicals

1

Which is a disadvantage of synthetic fertilizers?

Always improve soil structure

Can lead to eutrophication due to runoff

Are more expensive than organic fertilizers

Provide only micronutrients to crops

1

Which agricultural practice involves turning over the soil before planting?

Crop rotation

Tilling

Hydroponics

Polyculture farming

1

What is the most likely result of excessive fertilizer use?

Direct poisoning of aquatic life

Increased soil organic matter

Eutrophication in water bodies

Decline in pollinators

1

What is the largest human use of freshwater globally?

Drinking

Irrigation

Industrial processes

1

What happens in waterlogging?

Soil loses all its water

Soil erodes

Water table rises, reducing oxygen absorption

Plants receive excessive nutrients

1

What is the 'pesticide treadmill'?

The need for continuous pesticide use

Rotating pesticides to maintain effectiveness

Using pesticides to increase crop growth

Using lower pesticide amounts each year

1

What is an advantage of genetically modified crops?

Increased chemical pesticide use

Higher yields per hectare

Increased genetic diversity

No risk of cross-contamination

1

What is a primary reason for using CAFOs in meat production?

More cost-effective and efficient

Require more land than grazing

Produce higher-nutrition meat

Reduce water and soil pollution

1

What is an impact of overgrazing?

Increased soil fertility

Loss of vegetation and erosion

More efficient water use

Enhanced carbon sequestration

1

What is bycatch in fishing?

Intended catch

Fish caught and released

Unintended catch often discarded

The most profitable catch

1

How can individual consumers reduce overfishing impacts?

Choosing sustainable seafood

Eating only high-demand species

Avoiding all seafood

Supporting bycatch consumption

1

What happens as high-grade ores are depleted?

Ores become purer

Quality remains the same

Lower-grade ores become primary

Ores become renewable

1

What is acid mine drainage?

Water draining from acidic rock

Acids neutralized by mining

Strong acids dissolving minerals

Drainage increasing soil fertility

1

What is an impervious surface?

Surface allowing water to seep

Structure preventing water from soil

Enhancer of groundwater recharge

Soil type absorbing water quickly

1

How can cities reduce urban heat islands?

Build bridges to connect suburbs

Plant trees and green roofs

Remove parks to make space

Use heat-absorbing materials

1

What does sustainability aim to achieve?

Increased resource use over time

Use of resources without depleting them

Complete halt of resource use

Focus on short-term gains

1

What is sustainable yield?

Maximum profit from resources

Renewable resource use without depletion

Use of non-renewable resources

All available resources for use

1

What is urban runoff?

Rainwater flowing over surfaces into drains

Collecting rainwater for urban farms

Excess water from dams

Water diverted to farms

1

Which method increases water infiltration in cities?

Impermeable surfaces

Permeable pavement

Cutting down trees

Expanding paved areas

1

What is IPM?

Chemical pesticides only

Natural predators only

Combining multiple pest control methods

Exclusive crop rotation

1

What is an advantage of IPM?

Reduces pesticide risks to health

Simplifies pest control

Least expensive option

Eliminates all insects

1

What is rotational grazing?

Moving livestock to allow soil recovery

Keeping livestock in one pasture

Rotating crops, not livestock

Using synthetic meat alternatives

1

How does terracing benefit steep slopes?

Increases runoff speed

Reduces soil erosion

Encourages tree planting

Stops all vegetation growth

1

What is a disadvantage of aquaculture?

Disease transmission to wild fish

More fuel than traditional fishing

Less controlled environment

Fewer fish available for consumption

1

Why are prescribed burns used in forests?

Clear land for farming

Reduce uncontrolled wildfires

Remove wildlife from forests

Increase urban expansion
