What is an unintended consequence of large-scale agricultural use of water from an aquifer?

Back

The rate of water use likely exceeds the rate of recharge, leading to lowering the water table.

Front

What are CAFOs and their economic impact?

Back

CAFOs (Concentrated Animal Feeding Operations) make meat more economical but can lead to negative environmental impacts.

Front

Why are marine fisheries susceptible to the tragedy of the commons?

Back

Fish are highly migratory, so they don't belong to any one nation.

What are the environmental impacts of high concentrations of animal waste in CAFOs?

Back

High concentrations of animal waste can lead to nutrient pollution in water bodies, causing algal blooms and water quality issues.

Front

What is the role of international waters in marine fisheries?

Back

International waters are not owned by any one nation, making them susceptible to overfishing and the tragedy of the commons.
