Question

in 3-5 sentences, construct an argument for why beach nourishment is or is not a viable strategy to mange beach erosion​

Answer 1

Beach nourishment temporarily protects against erosion but can damage marine ecosystems and local economies, making it an unsustainable long-term strategy.

Step-by-step explanation:

Beach nourishment is a contentious strategy to manage beach erosion. By adding sand to eroding beaches, we can temporarily restore them, providing a buffer against storm impacts and protecting valuable beachfront properties. However, this approach has significant drawbacks, including potential damage to beach ecosystems, detrimental effects on marine life such as reefs and seagrass beds, and ultimately, negative impacts on local economies relying on fisheries and tourism. In fact, dredging to nourish beaches can increase vulnerability to storms due to altered underwater landscapes. As such, beach nourishment might be a viable strategy in terms of immediate effect, but it fails to be sustainable in the long-term and can cause more harm than good to marine ecosystems and local economies.
