As the nation's need for clean water grows, the eyes of many are falling upon the

vast but vulnerable Lake Michigan. However, regulators should not permit any additional
water diversions from the lake, an important resource for people living near its shore.
Each diversion is similar to a leak in an expensive swimming pool. The cumulative effect
of the leaks will eventually render the pool, Lake Michigan, vastly degraded. Regions and
municipalities with growing irrigation and drinking water needs should turn away from
Lake Michigan and focus on water conservation measures.

How does the use of an analogy affect the argument being made?
It likely oversimplifies the issue, but allows readers to visualize a complex issue in a way that is easier to understand.
It clarifies the argument, explaining how water conservation measures will be a more effective measure to take.
It signals that those who would be most impacted by the issue are the people who own expensive pools.

The analogy helps to illustrate the potential consequences of allowing additional water diversions from Lake Michigan. It compares the cumulative effect of these diversions to the degradation of an expensive swimming pool caused by multiple leaks. By using this analogy, the argument is able to convey the idea that each diversion may seem small individually, but when combined, they can collectively have a significant negative impact on the lake. This helps readers comprehend the potential harm that could be caused to Lake Michigan if additional water diversions are permitted.
