A beachside resort is losing beach space due to erosion of the sand. They have proposed the building of a breakwater off the coast in order to stop their beach from being eroded by the waves. The residents next to the resort have formed a group that is protesting the development of the breakwater for fear that it will cause their beach to erode. Do you agree with the residents that it will a breakwater will cause erosion to their beach? Briefly justify why you agree or disagree.
