A better working title might be "Negrils Evolving beach". I'm not sure you should start a documentary with a conclusion and pictures are not conclusive. Talk to Gail of Treehouse. Treehouse is often cited as a benchmark of beach health. Two years ago waves were washing the bar tops at her restaurant. Last year we could have a football game between the bar and the sea. Last week the sea floor was undulated and only waist deep at the buoy line. The only constant, without measure, is change.
