Fishing fleets are 40 percent larger than the ocean can sustain. Sincethe global economy has tripled in size and population has grown by 30 percent to 6 billion people. The analsysis, by the World Resources Institute WRI warns that if the decline continues it could have devastating implications for human development and the welfare of all species.

The analysis examined coastal, forest, grassland, and freshwater and agricultural ecosystems. The health of the each ecosystem was measured, as based on its ability to produce the goods and services that the world currently relies on.

To make matters worse, as our ecosystems decline, we are also racing against time since scientists lack baseline knowledge needed to properly determine the conditions of such systems. The four-fold increase in humans and the advent of the consumer society - have made the end of the millennium a cusp of history.

Affluent consumers in Hong Kong want exotic fish and presto! Poachers in the Philippines destroy vital reefs to meet that demand. Millions of workers in China and Russia are plagued with pollution-related ailments.

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. Damian Carrington 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 was much faster than official figures.

The new research estimates the peak catch was million tons, but declined at 1. Prof Daniel Pauly, at the University of British Columbia in Canada and who led the 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 our most complete picture yet of the global state of fish catches.

But afterfew undiscovered fisheries were 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. 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. 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. Jeremy Hance 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: 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. Hammill said the "most pressing issue" is plastic pollution.

Seabirds continually mistake plastic for fish eggs, devouring large amounts. Birds even feed plastic bits to their young, killing their fledglings en masse. In the end, large-scale actions to help seabirds could also go a long way in cleaning-up our increasingly trashed marine ecosystems.

All of these activities need investment 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.

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.

It also drives this ocean revitalizing train of currents through every major corner of the world ocean. This disruption could be caused by warmer, salty water cooling and sinking in the North Atlantic. And any disruption of the overturning process in the North Atlantic basically kills off a life-giving circulation to the entire world ocean system.
