Passage Summary: Critics say building in shallow water will hurt the dolphins' home, but the argument claims they are wrong because of the specific depths where these dolphins live.

Conclusion: The plan to build on land currently under five meters of water will not actually decrease the habitat available to the local dolphin population.

Reasoning: Dolphins are known to stay within a specific depth range (up to 30 meters), and their current habitat is physically constrained by land and much deeper water.

Analysis: We are looking for a logical bridge that explains why losing the 0-5 meter depth zone doesn't count as a loss of habitat. The most likely scenario is that the dolphins don't actually use that very shallow water to begin with. If the dolphins only frequent the 5-30 meter range, then building on the 0-5 meter range leaves their actual living space untouched. Look for an answer that clarifies the dolphins' depth preferences in a way that excludes the construction site.
