Question
[109]. Passage: Coastal erosion is driven by sea-level rise, storms, sand mining and hard structures that interrupt sediment flow. A seawall may protect one beach while starving the next of sand, shifting the problem along the coast. Mangroves, dunes and beach nourishment work with natural processes, absorbing wave energy and trapping sediment, but they need space and time to function. Planning therefore requires shoreline mapping, limits on mining, and retreat or adaptation in the most exposed settlements, rather than a wall at every threatened point. Which inference can be drawn from the passage?
Option 4 : The passage implies that protecting one stretch in isolation can worsen erosion elsewhere.
