Question

which image represents a disadvantage of living near the sea?

Explanation:

The first image shows people fishing, a benefit of coastal living. The second image depicts a flooded/eroded shoreline with damaged boats, which is a disadvantage (coastal flooding/erosion harms property and livelihoods). The third image shows stilt houses, an adaptation to coastal living, not a direct disadvantage.

Answer:

The second image (the middle one with the flooded shoreline and damaged boats)
