Coastal management is a way to protect beaches, oceans and the coasts of land from damage. It is like putting a protective shield around these areas so that people can enjoy them, but their environment is still safe. Coastal management includes things like building walls and other structures to protect the land from strong waves, creating artificial reefs to attract sea life, and making sure that new buildings and roads are not built in places that could harm the natural environment. Basically, it is a way to protect the special places we have near the sea and make sure they stay healthy and beautiful for generations to come.
