Question

Sand dunes.
Sand dunes protect beaches against erosion and flooding due to storms.

Which human activity would have the most negative impact on dune grasses and the coast?

driving vehicles along the beach
building houses near the beach
walking on the dunes of the beach
allowing kids to play on the beach

Answer 1

Driving vehicles along the beach would have the most negative impact on dune grasses and the coast. This activity can lead to significant disturbance of the sand dunes, compaction of the soil, and physical damage to the dune vegetation. It can also contribute to erosion and reduce the natural protective barrier that dunes provide against storms and flooding. While other activities like building houses and walking on the dunes can also have negative effects, driving vehicles typically causes more direct and severe damage to the ecosystems present in these coastal areas.
