Shipwrecks litter the coastal waters of the U.S.  (Source: Travellingblog.org)
Arggh yee, maties, she be a toxic PCB drifting off the starboard bow!

DailyTech has previously reported about the rising epidemic of tech trash.  The export of tech trash, largely from the U.S. to third world nations, has become an international problem which has gotten so bad the U.S. Congress is considering tough new measures to curb the effects.  However, while some tech trash may be getting dumped on foreign soils, there's another major realm of tech trash that is only now beginning to be fully recognized -- the sea.

Every year boats, barges and ships sink in coastal waters around the U.S. due to accidents, weather damage, age or an owner's financial duress.  The majority is never recovered and lay rotting on the seabed.  The problem has taken on high-tech ramifications, as modern boats often have onboard computers and circuitry, much of which contains toxic chemicals.

Doug Helton, acting director of the National Oceanic and Atmospheric Administration (NOAA) Marine Debris Program describes, "You go to any harbor or shoreline in the country and you'll find derelict and abandoned vessels."

There may be as many as 10,000 sunken vessels surrounding the U.S. coast, with 400 to 500 being sunk in 2005 alone, with the arrival of Hurricane Katrina.  The wrecks typically leach toxic petroleum into the surrounding areas says Mr. Helton.  And while the petroleum chemicals will drift away, the PCBs onboard the ships will not and continue to leach toxic chemicals.  Mr. Helton says that these chemicals move up the food chain and are likely to eventually be ingested by humans.

The wrecks can also destroy local ecosystems.  The leaching iron can attract corallimorph, organisms in the same family as corals and sea anemones, which attack and kill corals and other sea life.  This phenomenon was recently verified by Thierry Work, a wildlife disease specialist at the U.S. Geological Survey, and his colleagues, in the journal PLoS One. He describes, "It's a carpet of living animals that destroyed all the other organisms underneath.  We were able to show man-made structures were responsible for the growth of these organisms."

The wreckage can also directly kill fish and other sea creatures.  According to Keith Criddle, a marine policy professor at the University of Alaska in Fairbanks the leading killer of endangered monk seals is fishing equipment aboard wrecks.  A 2004 report titled "An Ocean Blueprint for the 21st Century," the U.S. Commission on Ocean Policy found that more than 267 different species were being adversely impacted by derelict fishing gear.

Professor Criddle and others have called on Congress to improve efforts to remove the marine trash, particular the fish equipment and toxic tech trash.  They say the biggest need is for a cohesive plan as their currently is a lack of organization in efforts.  While many states have fines for abandonment, often they are not strictly enforced and it’s less costly to take the fine that take apart the ship.  Breaking down a 40 foot yacht can cost as little as $5,000 to $10,000, but often it can cost up to 100 times that amount. 

Recently, Washington State has funded some efforts for boat removal and the U.S. Congress has given the NOAA some funding to remove boats from coral reefs.  While these efforts are helping, they cannot keep up with the pace of sinking ships, without more help.

One additional undesirable side effect of the PCB leaching has also surfaced -- "increased catchability".  While this may sound like a good thing, it’s a headache for fishers, as it causes regions to quickly be depleted of fish and lowers their overall revenue.

Mr. Helton says that with new government efforts technology aboard the ships and any fishing gear could be secured so the ship was not harming the environment, even if there were not funds to totally dismantle the ship.  He urges citizens as well to remember, "when a vessel is lost it's not gone."

Define "fact."

In science, a fact is a peer-reviewed statement that has been re-tested and proven to be true by a large majority.

Some facts can exist for a long time and be debunked at a later date. i.e. the world is flat.

It is widely agreed upon that ANY pollution is TOO MUCH pollution, as long as it's detrimental to nature it is also detrimental to us. "People polluting too much" is considered FACT by most Americans, it's why there's a huge green movement in all industries right now. If you don't think that people are polluting too much you're obviously a minority with your opinion. As for the rest of us, we can see the obvious. I'm sorry you can't. You'd rather sit here and argue semantics than actually get on board and try to make the world a better place.

What is truly sad, is that there are so many people with an "I-don't-care attitude" that are just taking up space and making life less enjoyable for those of us who do care and who want a brighter and better future for our children.

I for one believe in privacy, freedom, the right to be respected. I do not believe in ownership, I think capitalism is evil and so is money. Some might think of me as a hippy and that's ok. I'm a marketing major who dislikes capitalism, go figure. The fact is that those people fail to see the bigger picture of how money really is the root of all evil, and how it corrupts our society.

As a child, I was taught to share. It was a valuable lesson that is no longer part of American society. We simply do not share, unless we get a tax cut out of it which actually just means more money for us.

It is time to learn what honor and respect are. Get some.

Sharing was never part of the American society, however, there once was this place called the USSR.........
