'250 billion' plastic fragments in Mediterranean
People sunbathe beside the Mediterranean on Tel Aviv beach on Monday. Some 250 billion microscopic pieces of plastic are floating in the Mediterranean, creating a biological hazard that reverberates up the food chain, according to research supported by green campaigners.
Some 250 billion microscopic pieces of plastic are floating in the Mediterranean, creating a biological hazard that reverberates up the food chain, according to research supported by green campaigners.
The estimate comes from French and Belgian marine biologists who analysed water samples taken in July off France, northern Italy and Spain to a depth of 10-15 centimetres (four to six inches).
"The rough estimate is that there are roughly 250 billion pieces of micro-debris in all the Mediterranean," said Francois Galgani, of the French Institute for Exploration of the Sea (Ifremer), said.
The figure derives from 4,371 minute pieces of plastic -- average weight 1.8 milligrams (0.00006 of an ounce) -- found in the samples, "which extrapolates to roughly 500 tonnes for the entire Mediterranean," Galgani said.
Ninety percent of the samples, taken by volunteers from Expedition MED (Mediterranean in Danger) on a 17-metre (55-feet) yacht, had such fragments.
The sampling only covered surface waters and is a preliminary evaluation. Further samples, off Gibraltar, Moroccow, Algeria, Tunisa, Sardinia and southern Italy, will be taken in 2011 to get a wider picture.
Micro-sized plastic is an enduring hazard, as it becomes mixed with plankton, which is then ingurgitated by small fish that are then eaten by larger predators, says Expedition MED.
It says there is an accumulating pile of evidence of the damage that this does to larger forms of marine life, including seals and tortoises.
"The only solution is to stop micro-debris at the sources," said Expedition MED's Bruno Dumontet.
The group is launching an on-line petition to demand tougher European Union (EU) rules on the disposal and biodegrability of consumer goods.

The green movement is a legitimate and worthy cause. Alternative energy sources will be pursued if there is profit to be had (as a natural cause),.. this will occur once oil/coal become harder to extract and prices go up. That's just the reality. Artificially causing prices to go up is economic button pushing, social engineering and is reckless.

But the important point is that most of this debris is coming from homes in some cases over a thousand miles away, primarily due to plastic debris getting into the sewage systems, and from there into rivers.
Can sewage treatment plants in Europe do a better job? I think so. The other alternative is more use of biodegradable plastics.

Well, you can't extrapolate to the entire Mediterranean from samples taken off the coast of a few countries. You have to establish a gradient by sampling in a grid across the sea. The vast majority of the sea will have zero particles.

Perhaps the statement "The green movement WAS a legitimate and worthy cause" is more accurate. Unfortunately, it has been hijacked by the rulers of the world (not a reference to governments here). It is now being used as a mechanism to tap into the pocket books of every simpleton and half-wit with a paycheck on the planet. One way or another, the rich will get richer and the powerful more powerful.

It's more of a political movement. Progressives want a one world governance (via UN mandates, etc), and more left leaning influence over governments. In any case it was indeed hi-jacked.
The quickest way, in developing alternatives, will be with capitalism and free market, not contrary and across the grain of that force; ... there would be two battles to fight in that case, one political and one technological, an already loosing battle.

Human use of the ocean is NOT spread evenly over 100% of available ocean surface.
The part we do use usually has LIMITED out and inflow from the nearbye sea.
The usable part of the ocean is a small small fraction of its total area, say about 1% on coastlines.
Add in that human settlement favors enclosed, protected bays, or along smaller seas to avoid the constant threat from weather, and make shipping and travel easier and you create a situation where the OCEAN WE USE can be overwhelmed - as in quickly multiplying dead zones on various coasts nationwide.
The entire Mediterranean depends on one small opening to the Atlantic to dilute the deluge of filth washed into it from Europe the Middle East and Africa and the Black sea.
On the scale of Eons the Ocean will do fine.
Over a human lifetime though the danger is extreme.

List one item we import from Saudi Arabia or Iraq outside of oil.

Absolutely, but it's not within the remotest realm of possibility to "get off foreign oil" anytime soon without doing two things, fast-tracking a ton of new nuclear plants, and massive "drill, baby, drill".
To get off fossil fuels in general will take generations. If you want to do it in the short-term, get ready to commute on bikes to your buggy-whip manufacturing job. And even building that many new bikes will take decades.
There is no long-term transition plan to get us off fossil fuels, and it may not even be possible, unless there are some major cost breakthroughs in solar and wind power generation. And the enviro-freaks and NIMBY's are already out in force against turbines. Birds and bats and polar bears and other cute furries keep extincting themselves on the blades.

Good question, ask the democrats. About 85% of off shore drilling is under a federally mandated moratorium on drilling. You saw how reactionary the Obama Administration was after the oil spill last year, they stopped all drilling (!) with no apparent rationality. The democratic progressive environmentalists will stop drilling at every opportunity, counter to the best interest of the country. The last thing they want is lower priced oil.
Where's nuclear plants,... again, the government in the way.

When the common good and national interests are trumped by very narrow private interests there is a glaring problem that needs to be addressed.
Geothermal power is available almost everywhere, the US sits on huge natural gas reserves. Before we address the wants of the left or the right, we need to address the needs of the Nation with an eye on restoring prosperity by abandoning the Bretton Woods mentality and generating a positive trade balance by reducing imports.
BUT would you be willing to pay a premium for domestic fuel when foriegn sources underbid domestic suppliers?
If we are to recover economically, we need to keep the wealth from leaving the nation. When there is prosperity the is choice. Where there is choice there is freedom.

Our population is far more dispersed than Japan or Europe, so we would have to invest proportionately more in mass transit.
Finally, something I can agree with you on 150%.
So why can't we do both, nukes and drill? There have been major discoveries of both oil and gas in the US in the last decade. Everything needs to be on the table.

Oil is much more attractive than nuclear and other options due to the subsidies and tax breaks making the cost of doing oil business very cheap, allowing competitive edge. That has to stop. We've artificially selected the energy generation winner and they haven't substantially invested in technological improvements. That alone indicates it's time for a change from the way we've done business prior.

Thanks for your analysis. I have added Brian Regan's explanation: 'The big yellow one's the sun!, for simpler-minded people like myself.
I find the political implications of what you have shown to be extremely interesting. There are two ways to solve earth's resource problems. Solve the problems technically (quickly!) or reduce the population. Of course any 'reduction' in population does not include those implementing said reduction.
Individual people can be pretty cool, but the human race is insane(I know, meaningless legal term). Politicians and other clerics have always know the nature of humanity.
Our leaders, informed, visible or otherwise, do not view favorably a future determined by what is essentially an uncontrolled virus. If the problem is galactic, then remedy is insoluble. If the problem is human...Well, we do have history.
