“…Recreational activities are a major source of beach litter (Cundell, 1973;Dixon & Cooke, 1977;Nagelkerken et al, 2001;Pruter, 1987) as well as rubbish from ships at sea (Horsman, 1982;Price, Whitehall, & Bernard, 1987;Scott, 1975;. There are negative ecological effects of litter on seals (Merrell, 1980), fish and seabirds (Bourne, 1976;Day, Wehle, & Coleman, 1984;Degange & Newby, 1980;Furness, 1985;, as well as other marine mammals (Fowler, 1987;Perkins & Beamish, 1979;Shaughnessy, 1980) and turtles (Balazs, 1985). The effects include strangulation and entanglement in nets and strapping (Merrell, 1984;Wehle & Coleman, 1983), starvation and death from ingesting of plastics resulting in blockages and ulceration and/or damage to the delicate internal tissues of the stomach and intestines (Gramentz, 1988;Gregory, 1991;Laist, 1987;Wehle & Coleman, 1983), and concentration of synthetic chemicals up the food chain (Gregory, 1978;Wehle & Coleman, 1983).…”
