Environmental factors are overwhelmingly affecting the ocean’s capabilities to support the reproduction of seafood and scientists claim that there will be a collapse of all fished seafood by 2050. This study conducted by and international group of ecologists and economist was first reported in the November 3rd issue of Science.

The reason for this is that the ocean is being changed because species will not be able to resist disease, filter pollutants, they are over-fished, and the climatic temperature all with a dramatic time line happening by 2050.

"Whether we looked at tide pools or studies over the entire world's ocean, we saw the same picture emerging," said lead author Boris Worm of Dalhousie University. "In losing species we lose the productivity and stability of entire ecosystems. I was shocked and disturbed by how consistent these trends are - beyond anything we suspected."

"This analysis provides the best documentation I have ever seen regarding biodiversity's value," adds Peter Kareiva, a former Brown University professor and US government fisheries manager who now lead science efforts at The Nature Conservancy. "There is no way the world will protect biodiversity without this type of compelling data demonstrating the economic value of biodiversity."

The scientists say that there is still a chance for the ocean to recover. If no changes happen they predict that 90% of the species will be depleted by 2050. The problem they point out is that food for the ocean species count on other species. If one falls, another will also die off.

"Unless we fundamentally change the way we manage all the oceans species together, as working ecosystems, then this century is the last century of wild seafood," says co-author Steve Palumbi of Stanford University.

"This isn't predicted to happen, this is happening now," says co-author Nicola Beaumont an ecological economist with the Plymouth Marine Laboratory. "If biodiversity continues to decline, the marine environment will not be able to sustain our way of life; indeed it may not be able to sustain our lives at all."
