Industrial animal farms can produce large amounts of waste, which is often stored in large outdoor basins called waste lagoons. Under optimal conditions, the waste does not pose a direct hazard to the environment. However, faulty lagoons can leak, or severe weather can cause the
lagoons to flood and spill into the environment. Which of the following might be an effect of a leaking waste lagoon?
Runoff from a leaking lagoon could lead to soil erosion downstream.
Drinking water in groundwater aquifers could be contaminated.
The properties of soll downstream could be altered, affecting ecosystems.
Carbon dioxide emissions could increase and affect the global climate.
