A series of coral reefs is located near a coastline. In 3–5 sentences, construct an argument about how people can help prevent erosion to the coastline by protecting coral reefs.

People can help prevent erosion to the coastline by limiting the construction of seawalls and sandbags that lead to beach erosion. Communities should preserve natural sand dunes, as they protect the coastlines from erosion. Man-made sand dunes actually do the opposite. It is important to consider that natural sand dunes are made of layers of different types of sand, which enables the wind to gather sand in a specific spot instead of reducing it, while also allowing vegetation to grow deeper and protect the coastline.
