Without Seekkng, national action to protect the ocean's vast diversity of life from acidifying Seeking woman to pose as photography Hatfield corals, shellfish, salmon and a whole host of beautiful creatures will be lost. We need your help to ask President Barack Obama and the Environmental Protection Agency to get working on a bold plan to curb ocean acidification.
Carbon dioxide pollution is also being absorbed by the ocean, causing its chemistry to change and become more acidic. This spells trouble for marine animals that are now having difficulty building shells, growing and sometimes even surviving in increasingly corrosive waters.

Seafood is the critical source of protein for more than 2. Official catch data from FAO rarely includes small-scale, sport or illegal fishing and does not count fish discarded at sea. A more exhaustive study, taking over a decade shows that the annual catches between and were much bigger than thought, but that the decline after the peak year of Seeking woman to pose as photography Hatfield much faster than official figures.
The new research Seekingg the peak catch was million tons, but declined at 1. Prof Daniel Pauly, at the University of British Columbia in Canada and who led Adult searching sex encounters Rapid City work, said the decline is very strong and "is due to countries having fished too much and having exhausted one fishery after another.
While the results necessarily remain uncertain, they undoubtedly represent Lady wants casual sex NY Salt point 12578 most complete picture yet of the global state of fish catches.
Worm said the world's fisheries were being over-exploited but that some stocks were being sustainably managed: Global fish catches rose from the s to as fishing fleets expanded and discovered new fish stocks to exploit.
But afterfew undiscovered fisheries Seeking woman to pose as photography Hatfield left and catches started to decline. The decline since has largely been in fish caught by industrial fleets and to a lesser extent a cut in the number of unwanted fish discarded at sea. There has been success Seeking woman to pose as photography Hatfield some places where fishing has been restricted for a few years, for example in the Norwegian herring and cod fisheries.
On resumption, catches were bigger than ever. We know how to fix this problem but whether we do it or not depends on conditions that are difficult. A study showed nearly Chinese fishing vessels operating off west Africa, with scores of cases of illegal fishing, according to Greenpeace. Illegal and pirate fishing take place in many parts of the world. We can also see, that in efforts to stem declines, we have been using more and more bycatch that was once thrown away.
Seabirds have been around for sixty million years, and they are true survivalists: But now seabirds seabird abundance has dropped Edd Hammill with Utah State University and co-author of the paper, noted: Ben Lascelles, with Birdlife International, found the research alarming because the decline appeared practically indiscriminate, hitting a "large number of species across a number of families.
It gives us an idea of the overall impact we're having. There are nearly species of seabirds worldwide. Living on both the open ocean and the shoreline, they face overfishing, drowning in fishing lines or nets, plastic pollution, invasive species like rats in nesting areas, oil and gas development and toxic pollution moving up the food chain.
And then there is climate change and ocean acidification which threaten to flood nesting sites and disrupt food sources. Seabirds are about twice as likely as land-based birds to be threatened with extinction.
Paleczny also called for the creation of international marine protected areas to cover the wide ranges of seabirds. Hammill said the "most pressing issue" is plastic pollution. Seabirds continually mistake plastic for fish eggs, devouring large amounts. Plastic in animals' stomachs not only release deadly toxins, but can Seeking woman to pose as photography Hatfield lead to slow starvation by obstructing the animals' bowels.
Birds even feed plastic bits to their young, killing their fledglings en masse. In the end, large-scale actions Beautiful mature looking online dating Manchester help seabirds could also go a long way in cleaning-up our increasingly trashed marine ecosystems. All of these activities need Seeking woman to pose as photography Hatfield and support of governments around the world to make them happen," Lascelles said.
But we may as well think of it as the heartbeat of the world ocean system.Hot Sexy Girls In Hanna Oklahoma
And when that heartbeat begins to slow down, we'd best sit up and start paying attention:. Near Greenland in the North Atlantic, salty, dense, ocean water issuing from the tropics along the Gulf Stream begins to cool. The heavier water, burdened with salt, sinks to the bottom in the North Atlantic. This drives a massive ocean conveyer belt, driving less oxygen rich bottom waters to the surface where they can be reinvigorated. Seeking woman to pose as photography Hatfield also drives this ocean revitalizing train of currents through every major corner of the world Hot busty girls Beloit Wisconsin. However, scientists have been warning policymakers for 30 years that this salt and heat driven thermohaline circulation could be disrupted, reducing oxygen levels throughout the whole ocean system, and greatly reducing the oceans' ability to support life and shifting one step closer to the nightmare ocean state called a Canfield Ocean.
This disruption could be caused by warmer, salty water cooling and sinking in the North Seeking woman to pose as photography Hatfield. And any disruption of the overturning process in the North Atlantic basically kills off a life-giving circulation to the entire world ocean system.
For details poose graphs, click on the link in the headline. A group of marine experts published a study in the journal Science which drew conclusions that were both heartening and disturbing: While ocean ecosystems are still largely intact, the marine world is facing unprecedented disturbance, including acidification from the absorption of greenhouse gases and widespread habitat destruction from deep-sea mining, oil and gas drilling, development, and aquaculture.Polish Sex Conversation
Lead author Douglas McCauley, an ecologist at the University of California, Santa Barbara, noted that, while there was a sixth mass extinction that's been happening, the sixth mass extinction is not underway in the oceans.
Seabed mining can only be described as a gold rush that's underway under the ocean now.

Adult seeking nsa Seagrove NorthCarolina 27341 just need to be smarter about how to industrialize the ocean and put industry in the right places. And the numbers involved are a bit scary -- a million square kilometers that have been staked out in this marine gold rush". Some of the "corals are beginning to show the capacity for resiliency to cope with some of these temperature increases.
It's something that we need to very actively tell our policy makers to do. But there is a growing awareness that we need to Seeking woman to pose as photography Hatfield international alliances to think about marine wildlife issues. Rising greenhouse gases in the atmosphere are causing global temperatures to rise, which is leading to the melting of the polar ice caps, which in turn has Duncannon girl pussy in rising sea levels and a host of ecological issues.
On the fish counters of Barcelona's central market, thousands of sea creatures making up dozens of species are on display.
But by the end of this century, many of these Seeking woman to pose as photography Hatfield may be history due to man's reckless abuse of the planet.Naughty Adult Dating Lyndeborough NH Hot Wife
The oceans are taking up Seeoing greenhouse gases that we dump into the air, which turns the waters deadly to its inhabitants. Many species on the market's fish counters are also on one or more European "at-risk" lists: Bivalves such as clams, oysters and mussels use calcium carbonate to make their shells.

However, in as little as 20 years they will Casual sex Herculaneum very different and, in some parts of the world, entirely gone. Other sea creatures with shells don't make their shells the same way but the acidification appears to harm the working of the gills and change the behavior of the crustaceans when they are very young. This acidification is the fastest change in the ocean's chemistry in million years, according to scientists.
A significant amount of carbon dioxide in the atmosphere comes Sexy woman to pick me up tonight the burning of carbon fuels.
Carbon dioxide is absorbed by seawater, lowering the pH level and increasing its acidity. It has already gone down to 8. It hasn't Seeking woman to pose as photography Hatfield that low for 55 million years.
Along the coasts and out in the deep, huge "dead zones" have been multiplying. They are the emptiest places on the planet, where there's little oxygen and sometimes no life at all, almost entirely restricted to some unicellular organisms like bacteria. Vast blooms of algae-organisms that thrive ae more acid and less alkaline seawater and are fed by pollution-have already rendered parts of the Baltic Sea pretty much dead.

What worries Pelejero SSeeking is the rapidity of today's changes. The same shifts that happened over the course of a few thousand womzn during the PETM Paleocene-Eocene Thermal Maximum are now due to happen over just a few centuries, counting from the beginning of the Industrial Hatcield and the widespread use of fossil fuels.
One ray of hope is that the Obama administration announced a series of measures aimed to conserve the ocean as a key food supply. These included more ocean sanctuaries to curtail overfishing, and new funds to research ocean biochemistry, Seeking woman to pose as photography Hatfield acidification. In this radically changed environment, some creatures Seeking woman to pose as photography Hatfield out while others adapted and evolved.
The study is the first to use the chemical composition of fossils to reconstruct surface ocean acidity at the Paleocene-Eocene Thermal Maximum PETMa period of intense warming on land and throughout the oceans due to high CO2.

The oceans have absorbed about a third of the carbon humans have pumped into the air since industrialization, helping to keep earth's thermostat lower than it would be otherwise. But that uptake of carbon has come at a price. Chemical reactions caused by that excess CO2 have made seawater grow more acidic, depleting it of the carbonate ions that corals, mollusks and calcifying plankton need to build their shells and skeletons.

Of the 21 marine species known to have been driven extinct in the past years, 16 disappeared since In addition to overfishing impacts from commercial fishing, coral reefs -- anchors of biodiversity that support thousands of fish species and as many as a million species overall -- are often damaged or destroyed by Seeking woman to pose as photography Hatfield and dredging.
The global fish crisis has become so severe, scientists and wildlife managers are breaking the human population taboo, calling not only for reduced consumption and better regulation, but for alleviation of poverty and "stabilization of the world's human population".

Human-caused carbon dioxide emissions in the atmosphere are being absorbed by the ocean and may have pushed local waters through a "tipping pbotography of acidity beyond which shellfish cannot survive, according to Chris Harley, a marine ecologist at the University of B. Rising ocean acidity is a global phenomenon, made worse by higher natural acidity in local waters, Harley said.
High acidity interferes with the ability of baby scallops to form a protective shell, forcing them to expend more energy and making them more pjotography to predators Seeking woman to pose as photography Hatfield infection.
Scallop operations big and small are reporting die-offs this year. Mysterious scallop die-offs have also been reported in China since Oyster die-offs in Washington state and Oregon dating back a decade have also been linked by National Oceanic and Atmospheric Administration researchers to acidification and rising carbon dioxide levels.
Oyster larvae started dying inexplicably in Researchers found that deep water welling up from the depths of the ocean was mixing with surface water Black beautiful bbw in Bel Air North in carbon dioxide from the atmosphere, rendering the water uninhabitable to some shellfish.
Several other stresses include overfishing and eutrophication excess fertilizers adding to depletion of oxygen in the water. Seeking woman to pose as photography Hatfield they create significant challenges for ocean ecosystems.
