Explain how failing to conserve water can lead to an increase in water contamination.

Crop irrigation is one way in which freshwater resources are consumed. Failure to conserve water during irrigation can lead to an increase in pollution that results from runoff. Natural filters are diminished by the overuse of water resources, which leads to an increase in water contamination that would have been filtered by these natural sources. With the increased demands placed upon sewage systems comes an increased likelihood of sewage system failures, which is another potential increase in water contamination.

Explanation:

This is the "possible answer" E2020 gives you at the end of the test.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
