Examine how humans interact with one of the following surface processes: - River processes - Leaving Cert Geography - Question 1C - 2020

Humans interact with coastal processes in various ways, such as through construction and tourism. One major interaction is the construction of sea walls and jetties.

Interaction

The construction of sea walls is designed to protect coastal infrastructure from erosion caused by waves. This interaction helps prevent property loss and maintains land use near coastlines. However, the presence of sea walls can also lead to negative environmental impacts, such as increased erosion at adjacent locations.

Explanation of Specific Reference Points (SRPs)

1. Protection from Erosion: Sea walls effectively absorb wave energy, reducing the impact on coastal areas. This helps safeguard homes, businesses, and roads.

2. Increased Erosion Elsewhere: While protecting certain areas, sea walls can exacerbate erosion in unprotected neighboring zones, leading to long-term environmental changes.

3. Tourism Impact: Coastal developments attract tourists, boosting local economies. However, environmental degradation due to over-tourism can result in habitat loss and pollution.

4. Recreation Activities: Human activities such as swimming, surfing, and fishing can alter natural wave dynamics and sediment distribution, impacting local ecosystems.

5. Changes in Wildlife Habitats: Coastal development can disrupt the natural habitats of wildlife, impacting species that rely on the beach and nearshore environments for breeding and feeding.

6. Pollution: Increased human traffic and development can introduce pollutants into marine environments, adversely affecting water quality and marine life.

7. Management Strategies: Initiatives such as beach nourishment and conservation efforts are crucial for mitigating negative impacts, promoting sustainable interactions with coastlines.

8. Adaptation to Climate Change: Coastal areas face rising sea levels; hence, human interaction must incorporate adaptive measures like managed retreat or enhanced sea defenses.

9. Community Engagement: Local communities are moving towards more sustainable practices for coastal management, focusing on balancing economic development with environmental conservation.
