The shoreline is ever changing. When I first started going to Negril in the mid-80's, the beach at Treehouse was 40' out from the bar. Big change but they usually still have some beach. Where I stay at the other end has also lost beach but it was a much, much larger area to begin with. Beach renourishment here in FL often gets taken away after the beach communities & governments (federal aid not uncommon) spend many hundreds of thousands of $$$, if not more. Mother Nature will do what she does as far as the beach goes. Usually it comes & goes :-)
