In 3–5 sentences, construct an argument for why beach nourishment is or is not a viable strategy to manage beach erosion. (4 points)
Beach nourishment is a viable strategy to manage beach erosion as it helps to restore the natural beach ecosystem and provides an immediate solution to prevent further erosion. By adding sand to eroded beaches, it serves as a protective barrier against future erosion caused by coastal storms and high tides. Additionally, it can also support tourism and recreational activities, which are crucial sources of income for coastal communities. However, it is important to consider the long-term sustainability and cost-effectiveness of beach nourishment, as it requires constant maintenance and can have negative impacts on adjacent ecosystems.
In 3–5 sentences, explain the various factors that should be considered when implementing green roofs.(4 points)
When implementing green roofs, several factors should be considered. Firstly, the structural capacity of the building needs to be evaluated to ensure it can support the weight of the green roof. Secondly, the climate and weather patterns of the region should be assessed to determine the type of vegetation that can thrive on the rooftop. Additionally, the maintenance requirements, including irrigation, pruning, and pest control, need to be considered to ensure the longevity of the green roof. Lastly, the potential benefits such as energy savings, stormwater management, and improved air quality should be analyzed to assess the overall cost-effectiveness of the green roof installation.
