All of these activities need investment and support of governments around the world to make them happen," Lascelles said."These actions will build resilience in the seabird populations in the short term, which they need in the face of emerging threats such as climate change." Scientists call it Atlantic Meridional Overturning Circulation (AMOC)."We can see how industrial fisheries from developing countries are robbing these people of livelihoods and food.

Paleczny and Hammil's research found that the tern family has fallen by 85%, frigatebirds by 81%, petrels and shearwaters by 79%, and albatrosses by 69%.

Lascelles said: "Increased efforts should be made to rid seabird colonies of invasive species, reduce bycatch in fisheries or the ensnaring of birds in fish nets, and setting up conservation areas." Paleczny also called for the creation of international marine protected areas to cover the wide ranges of seabirds.

While the results necessarily remain uncertain, they undoubtedly represent our 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: "Where such measures have been taken, we find that both fish and fishermen are more likely to persist into the future." Global fish catches rose from the 1950s to 1996 as fishing fleets expanded and discovered new fish stocks to exploit.

But after 1996, few undiscovered fisheries were left and catches started to decline.

Currently, only 2% of the world's oceans are under some form of protection and less than half of those ban fishing altogether.

In contrast, nearly 15% of the world's terrestrial landscape is protected.

In the end, large-scale actions to help seabirds could also go a long way in cleaning-up our increasingly trashed marine ecosystems.

"The oceans are still woefully under protected and fisheries need greater management and enforcement.

It gives us an idea of the overall impact we're having." There are nearly 350 species of seabirds worldwide.
