Scary world were living in... funny the terrorist don't worry me nearly as much as pollution and over population does, it seems more of a threat to our future.
hmm I had my favorite sea food saturday night deep sea Swordfish hope the Mercury level was low. /ccboard/images/graemlins/frown.gif

WASHINGTON (AP) -- Clambakes, crabcakes, swordfish steaks and even humble fish sticks could be little more than a fond memory in a few decades.

If current trends of overfishing and pollution continue, the populations of just about all seafood face collapse by 2048, a team of ecologists and economists warns in a report in Friday's issue of the journal Science.

"Whether we looked at tide pools or studies over the entire world's ocean, we saw the same picture emerging. In losing species we lose the productivity and stability of entire ecosystems," said the lead author Boris Worm of Dalhousie University in Halifax, Nova Scotia. (Watch how the seafood on your plate may become a thing of the past -- 3:10)

"I was shocked and disturbed by how consistent these trends are -- beyond anything we suspected," Worm said.

While the study focused on the oceans, concerns have been expressed by ecologists about threats to fish in the Great Lakes and other lakes, rivers and freshwaters, too.

Worm and an international team spent four years analyzing 32 controlled experiments, other studies from 48 marine protected areas and global catch data from the U.N. Food and Agriculture Organization's database of all fish and invertebrates worldwide from 1950 to 2003.

The scientists also looked at a 1,000-year time series for 12 coastal regions, drawing on data from archives, fishery records, sediment cores and archaeological data.

"At this point 29 percent of fish and seafood species have collapsed -- that is, their catch has declined by 90 percent. It is a very clear trend, and it is accelerating," Worm said. "If the long-term trend continues, all fish and seafood species are projected to collapse within my lifetime -- by 2048."

"It looks grim and the projection of the trend into the future looks even grimmer," he said. "But it's not too late to turn this around. It can be done, but it must be done soon. We need a shift from single species management to ecosystem management. It just requires a big chunk of political will to do it."

The researchers called for new marine reserves, better management to prevent overfishing and tighter controls on pollution.

In the 48 areas worldwide that have been protected to improve marine biodiversity, they found, "diversity of species recovered dramatically, and with it the ecosystem's productivity and stability."

While seafood forms a crucial concern in their study, the researchers were analyzing overall biodiversity of the oceans. The more species in the oceans, the better each can handle exploitation.

"Even bugs and weeds make clear, measurable contributions to ecosystems," said co-author J. Emmett Duffy of the Virginia Institute of Marine Sciences.

The National Fisheries Institute, a trade association for the seafood industry, does not share the researchers alarm.

"Fish stocks naturally fluctuate in population," the institute said in a statement. "By developing new technologies that capture target species more efficiently and result in less impact on other species or the environment, we are helping to ensure our industry does not adversely affect surrounding ecosystems or damage native species.

Seafood has become a growing part of Americans' diet in recent years. Consumption totaled 16.6 pounds per person in 2004, the most recent data available, according to the National Oceanic and Atmospheric Administration. That compares with 15.2 pounds in 2000.

Joshua Reichert, head of the private Pew Charitable Trusts' environment program, pointed out that worldwide fishing provides $80 billion in revenue and 200 million people depend on it for their livelihoods. For more than 1 billion people, many of whom are poor, fish is their main source of protein, he said.

The research was funded by the National Science Foundation's National Center for Ecological Synthesis and Analysis.

That post was just liberal bullshit. I say don't give a
hoot, pollute. If my President says it's not a problem;
it's not a problem.

After I saw that special on fish hotels in TLC, I stopped eating sushi.
Then those prawns and shrimp hotels in Thailand made me sick. They cage all those shrimp and feed them anti-biotics to combat diseases. They also live on dirty water instead of the open ocean.
I'm not eating farmed fish and shrimp.
The govt. of all nations ought to start breeding fish then release them to the ocean.

It's Bush's fault.

It's a well known fact that Bush and Rove enjoy fishing with nuclear depth charges cause they hate fish.

Some other things that are his fault:
Wildfires
Hurricanes
Volcanos
Athlete's Foot and Jock Itch
Yeast Infections
Anal Itch
Cannibalism
......blah, blah, blah , blah.... /ccboard/images/graemlins/tongue.gif

Does this also mean that hush puppies are in immediate danger? /ccboard/images/graemlins/shocked.gif

Keep your eye on the plankton and algae populations. Fish I don't worry about so much. If the micro level gets messed up we are all dead.

The No1 problem is the health of the future environment. If so, i agree, the No2 problem is overpopulation. If so, the No3 problem is ignorance. If so, the No4 problem is religion (ie muslim and christian etc). And we can include No5, economic ignorance (and economic selfishness).

My billiard mate's son looked at it a bit differently -- he said that, if ignorance is the problem, and if education is the answer, then the main problem is in fact communication. But i pointed out the main flaw in his reasoning -- i pointed out that communication is totally wasted on a Libertarian.
