Found on beaches and at all depths of the ocean, marine debris consists of all forms of trash, including plastics, paper, wood, metal and other manufactured materials.
Marine debris in Israel is over 70% plastic. Most of the litter is left by beach-goers (Golik & Gertner, 1992).
Approximately 20% of marine debris, or 636,000 tons per year, comes from ocean vessels (US Department of Commerce 1999; Ramirez-Llodra et al. 2011).
Cruises represent only 1% of marine vessels, but produce 25% of ship-sourced waste.
On average, a single cruise passenger produces 3.5 kg of waste per day (Butt 2007).
How Was It Measured?
The "Clean-coast Index"9 reports from the Israel Ministry of Environment was used. This index reports the amount of plastic trash (>2 cm size) on beaches that are not declared for swimming, since beaches that are declared for swimming are sieved through regularly. The index assumes that plastic trash represents all trash present on the beach.
Amount of Plastic Trash "Clean-coast Index" Categories
0-2 Very Clean
>20 Very dirty
The official target for the "Clean beach index" is 70% of the beaches clean/very clean 70% of the time. We revised our target to: all of the beaches clean/very clean 70% of the samples, thus conforming with the official targets to a great extent.
