How can failing to conserve water contribute to greater water contamination? a. over-irrigating 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

The answer is a. Water conservation  involves managing water resources sustainably (reducing wastage) and ensuring that water sources are not depleted since water is not an infinite resource. Therefore, irrigation methods should include drip irrigation that conserves the water. Overhead irrigation cause washing off of pesticides from the plants and runoffs to water bodies. This renders fresh water undrinkable due to its hazardous nature to living organisms such as humans.
