Examine how humans interact with one of the following surface processes: • River processes • Coastal processes • Mass movement processes. - Leaving Cert Geography - Question 28 - 2019

The construction of coastal infrastructure can lead to increased erosion rates. As buildings are erected close to the shore, they can disrupt natural sediment flow, which can result in the loss of beach area and affect coastal ecosystems. Additionally, this can create a feedback loop, where erosion necessitates further human interventions, such as seawalls or riprap, thereby further altering the natural process.

Another significant interaction involves tourism and recreational activities at coastal areas. This includes beach tourism, water sports, and marine recreation, which can impact both the social and ecological landscape.

Tourism leads to increased human presence in these areas, which can contribute to pollution through littering and waste disposal. Furthermore, overuse of certain areas can lead to habitat degradation, which affects local wildlife and can impact the overall health of marine ecosystems.

A relevant annotated diagram could illustrate coastal development near the shoreline, indicating the erosion and the measures taken like seawalls. This would visually represent the described interactions and their consequences.
