There will be virtually nothing left to fish from the seas by the middle of the century if current trends continue, according to a major scientific study.
Stocks have collapsed in nearly one-third of sea fisheries, and the rate of decline is accelerating.
Writing in the journal Science, the international team of researchers says fishery decline is closely tied to a broader loss of marine biodiversity. - bbc
This is a vast piece of research, incorporating scientists from many institutions in Europe and the Americas, and drawing on four distinctly different kinds of data.Catch records from the open sea give a picture of declining fish stocks.
In 2003, 29% of open sea fisheries were in a state of collapse, defined as a decline to less than 10% of their original yield.
Bigger vessels, better nets, and new technology for spotting fish are not bringing the world's fleets bigger returns - in fact, the global catch fell by 13% between 1994 and 2003.
Historical records from coastal zones in North America, Europe and Australia also show declining yields, in step with declining species diversity; these are yields not just of fish, but of other kinds of seafood too.
I suppose they might just leave the plans out for nuclear bombs where anyone could read them if they really wanted to have some big wars.
