Millions of tons of plastic waste are dumped into the sea each year to present a serious threat to whales. Details of the conclusions will be revealed in an international maritime forum which took place on 11 to July 14, 2011 in Jersey, UK.
For example, in 2008, two sperm whales that stranded on the coast of California, USA, has 205 pounds of fishing nets and plastic garbage fragments in his body. One of them has a damaged stomach. An other, in conditions of hunger, has a lot of plastic garbage that blocks the digestive tract.
Seven sperm whales stranded in southern Italy in 2009 also found to have swallowed hook, line, and other plastic objects. Another whale, who was found dead in waters off France in 2002, even had swallowed nearly a ton of garbage, including plastic bags of two well-known supermarket in the UK.
