Question

How can failing to conserve water contribute to greater water contamination?
a.
Overirrigating fields causes an increase in pollution that results from runoff.
b.
Natural water filters are depleted by the overuse of water.
c.
Sewage systems are more likely to fail due to greater demand, causing higher chances of water contamination.
d.
All of the above

Answer 1

d. All of the above

All three effects are correct: excess irrigation increases polluted runoff, overuse can degrade wetlands and groundwater recharge that naturally filter water, and higher demand can overload or cause failures in sewage systems, increasing contamination risk.
