Abstract Marine debris (marine litter) is one of the most pervasive and solvable pollution problems plaguing the world’s oceans and waterways. Nets, food wrappers, cigarette filters, bottles, resin pellets, and other debris items can have serious impacts on wildlife, habitat, and human safety. Successful management of the problem requires a comprehensive understanding of both marine debris and human behavior. Knowledge is key for consumers to make appropriate choices when it comes to using and disposing of waste items. Education and outreach programs, strong laws and policies, and governmental and private enforcement are the building blocks for a successful marine pollution prevention initiative. The plastic industry also has a role to play in educating its employees and customers, and searching for technological mitigation strategies.

Paper or Plastic?
The new documentary film by Jimmy Wardell on our addiction to plastic and its consequences for our ocean planet, "Paper or Plastic?", will premiere at the Sundance film festival in January 2008. Keep an eye out for the exact time and venue and for it to come to a festival near you.

Blue Ocean Society's Plastic facts
Plastic Facts:
Marine litter can be defined as any man-made object present in the marine environment
50% or more of marine litter is in some form of plastic. Examples include: raw plastic pellets, plastic bags and sheeting, monofilament fishing nets and multi-pack soda can holders
Plastics have been extremely beneficial for humans in that they are more durable, lightweight, cheap and versatile as opposed to traditional materials such as wood or glass.
However, it is exactly the lightweight nature of plastics which can make them deadly in the marine environment, as plastic items can float on the surface of the ocean or within the water column
Plastics are composed of long chains of hydrocarbons, which are hydrogen and carbon atoms that are bound together very tightly.
Micro-organisms such as plankton do not have the ability to break down these bonds and therefore plastic does not decompose easily.
Plastics are the most common man-made object sighted at sea. During a 1998 survey, 89% of the trash observed floating in the North Pacific Ocean was plastic
The raw form of plastics, called resin pellets, constitute a large part of marine debris, but unfortunately they are relatively unnoticed.
Many common plastic objects such as bottles, sheeting and Styrofoam cups were found on remote Arctic beaches of the southern Beaufort Sea.
In 1960, almost 6.3 billion pounds of plastic was produced in the United States. By the early 1970's the figure had tripled and continued to increase to a volume of approximately 50 billion pounds in 1988. This is more than 10 pounds of plastic for every person on earth!
The packaging industry used more than 14 billion pounds of plastics in 1987 with nearly all of that ending up as waste.
Plastic sheeting has been documented in the stomachs of sperm whales, round-toothed dolphins and a Curvier beaked whale.
Many sea turtles frequently swallow plastic bags when they mistake them for jelly fish, which is one of their favorite foods.
One turtle found in New York had actually consumed 590 feet of heavy duty fishing line!

Perhaps rubber duckies don't belong in tub
http://www.akaction.org/ published a press release and story in ADN:
Alaskans discover nasty things about plastic
Perhaps rubber duckies don't belong in tub

Want to know what toxic chemicals are floating around in congressional candidate Ethan Berkowitz's blood? How about in an Alaska fisherman's urine? Both men participated in a national study on detecting what compounds from common household products stay with us.
The results? Not good for either of them, according to Alaska Community Action on Toxics. The nonprofit is pushing for legislation to ban what it says is poisoning us -- substances used mostly to make plastics.
The chemical groups tested have scary names: Phthalates, Bisphenol A (BPA), and Polybrominated diphenol ethers (PBDEs).
The first are used in vinyl products like shower curtains and rubber duckies. The second are used to make baby bottles and linings of metal food cans. The third are toxic flame-retardants added to plastic on things like televisions and computers.
PBDEs were found in very high rates in both Berkowitz, 45, and the Haines fisherman, 54-year-old Tim June, an environmental activist who co-founded Alaska Clean Water Alliance. Both volunteered with three other Alaskans and 30 other Americans for the national study called "Is It In Us?" done by a coalition working for greater regulation of manufacturers using the chemicals.
"It's no great source of pride that I have some of the highest levels among the participants across the 50 states," Berkowitz said after a press conference in Anchorage on Thursday.
"It could be that I spend too much time in front of the computer. It could be that my mattress has bad chemicals in it. It could be too much time in airplanes. It could be the cell phone. I just don't know what it is," said the former state House minority leader. "But it is more than my individual use of products that's contributing to this. Everyone of us that participated in this project has different personal habits and everyone of us has some level."
The hazardous products on display at the press conference included a Nalgene bottle, a toaster, a My Little Pony and a rain jacket.
The study sponsors say the chemicals have been linked to birth defects, cancer, infertility and a host of other health problems. But it's not clear if any of the pollutants is making anyone sick, according to the Centers for Disease Control, which says more research is needed.
Patricia Hunt, a molecular expert at Washington State University who was not part of the study, said BPAs are of particular concern because a growing body of literature shows that even a low dose may affect fetal development.
Phthalates, used to soften plastics, have been banned in toys in Europe. California has imposed a similar ban on certain types of Phthalates in toys beginning in 2009. California also has a ban on certain types of PBDEs which takes effect in 2008.
In Alaska, Rep. Andrea Doll, D-Juneau, plans to present a bill banning PBDEs.
Pamela Miller, executive director of the Alaska anti-toxic group, said the chemicals may be getting into us from food containers, or maybe from breathing them, for example, when we take hot showers and the plastics on the shower curtain are released. They are also found in household dust, she said.
"The problem is they're everywhere in our environment," Hunt said. "You can't actually see when you are being exposed. ...We can't go completely crazy because it's impossible to really remove plastics from our lives. But we can think differently about how we use it."
She no longer microwaves food in plastic containers, she said. She also doesn't put them in her dishwasher because the heat may be releasing the chemicals.
The other Alaskans who volunteered to be tested were Cathy Rexford, the Alaska director of Native Movement; Lori Townsend, an Alaska News Nightly journalist; and Democratic congressional candidate Diane Benson.
