Is ocean garbage killing whales?
As you already know, OMG founders Olivia and Carter are always trying to raise awareness to the issue of Plastic Pollution and the affects it has on our endangered species. They started OMG in an effort to save endangered species and quickly realized the need to help clean up the environment goes hand-in-hand with their efforts.
Since plastic is the #1 pollutant in our oceans, they are working hard to help educate children around the world about the problem and to help find solutions. This story was posted by the website “english.sina.com” and it further demonstrates how sever the issue has become. We hope you will share this with your friends and help us raise awareness around the world.
We also ask that you consider signing our “Say No To Plastic Bags” petition and that you consider mentioning our “Plastic Awareness Week” Program to your local schools. We would love to help them bring the program to their students as well.
“Millions of tonnes of plastic debris dumped each year in the world’s oceans could pose a lethal threat to whales, according to a scientific assessment to be presented at a key international whaling forum this week.
A review of research literature from the last two decades reveals hundreds of cases in which cetaceans — an order including 80-odd species of whales, dolphins and porpoises — have been sickened or killed by marine litter.
Entanglement in plastic bags and fishing gear have long been identified as a threat to sea birds, turtles and smaller cetaceans.
For large ocean-dwelling mammals, however, ingestion of such refuse is also emerging as a serious cause of disability and death, experts say.
Grisly examples abound.
One of the 50-foot animals had a ruptured stomach, and the other, half-starved, had a large plug of wadded plastic blocking its digestive tract.
Seven male sperm whales stranded on the Adriatic coast of southern Italy in 2009 were stuffed with half-digested squids beaks, fishing hooks, ropes and plastic objects.
In 2002, a dead minke whale washed up on the Normandy coast of France had nearly a tonne of plastic in its stomach, including bags from two British supermarkets.
“Cuvier’s beaked whales in the northeast Atlantic seem to have particularly high incidences of ingestion and death from plastic bags,” notes Mark Simmonds, author of the report and a member of scientific committee of the International Whaling Commission (IWC), which meets this week from July 11-14 on the British island of Jersey.
How widespread the problem is, and whether it could threaten an entire population or species, remains unknown.
“In many areas of the world, stranded whale carcasses are not recorded or examined, and in areas where strandings are recorded, examination of gut contents for swallowed plastics is rare,” said Chris Parsons, a marine biologist at George Mason University in Fairfax, Virginia.
“There is, however, evidence that plastic debris in the seas can harm these animals by both ingestion and entanglement, and this needs to be urgently further investigated,” said Simmonds, Director of Science for Whale and Dolphin Conservation Society.
The main threats to cetaceans worldwide are accidental capture in fishing nets and climate change, he noted in an email exchange.
“We don’t yet know enough about marine debris to rank it against other theats, but as it continues to sadly grow in the oceans, it will surely play a greater and greater role.”
Studies have shown that litter concentrates in so-called convergence zones — formed by currents and wind — where whales feed on abundant prey.
In 2003, the United Nations Environment Programme (UNEP) established the Global Initiative on Marine Litter, but it launched a detailed analysis of the scope of the problem only in 2009.
More recently, representatives from 38 countries meeting in Hawaii in March adopted the “Honolulu Commitment” outlining a dozen voluntary measures.
For whales, the level of threat from ocean garbage varies according to species and type of debris, the new report said.
Sperm and beaked whales are thought to be especially vulnerable because they are suction feeders.
Less is known about the impact on filter-feeding or baleen whales (suborder Mysticeti), which consume huge quantities of tiny zooplankton and small, schooling fish.
A single blue whale, for example, eats up to 3,600 kilos (8,000 pounds) of krill each day during feeding season.
Potentially, the greater danger here is from toxins in plastic that breaks down over time into tiny, even microscopic, particles.
Collisions with ships, and tissue-damaging noise pollution from off-shore oil exploration are additional threats, experts note.
The IWC is riven between countries that oppose whale hunting, and those that back the handful of nations — Japan, Iceland and Norway — that defy a 1986 whaling ban or use legal loopholes to circumvent it.”
