Sand dune erosion is caused by excavating, building roads, hotels, restaurants, and walkways on the beach causing sand dune erosion by disrupting the natural sediment process.
Threats to sand dunes include naturally occurring and human caused erosion.
Sand dune erosion is a bad example of how human activities negatively influence the posteriority of landforms to erode.
The biggest dangers to coastal areas is sea level rise, which may lead to loss of habitat and salinisation of soils, causing changes to the distribution of plants and animals, which overall concerns ecosystems.
Most change is caused by climate change because it threatens coastal areas, which are already stressed heavily by human activity and pollution.
Sand dunes are good because they provide natural coastal protection and provide important ecological habitat.
Other than storms, the other major cause of damage to dunes is people walking/playing on sand dunes; we damage the beach, grass and other plants that hold the dune together, over time the dune will be lost along all its efforts, and we take the sand with us when we leave the beach.
What we can do to protect the sand dunes: do not walk, picnic, ride bikes/play on the dunes as you will destroy the flora and fauna that depend on them – including the natural beauty, and the dependency the Caretta-caretta sea turtles have on a sandy beach to safely lay their eggs.
In Laganas, the infrastructure is built on the beach and the sand is disappearing from under these buildings, even the car park is on the beach, which is supposed to be a National Marine Park of Zakynthos protected area.
