9% of edible fish and seafood species have declined by 90%
A top international team of ecologists and economists have predicted that all saltwater fish will be totally extinct by the year 2048.
The worrying prediction is said to be a result of overfishing, pollution, habitat loss, and climate change.
According to a study by Boris Worm, PhD, of Dalhousie University in Halifax, Nova Scotia, along with colleagues in the U.K., U.S., Sweden, and Panama, 29% of edible fish and seafood species have declined by 90%.
The researcher analyzed several different types of data which delivered shocking results.
“I was shocked and disturbed by how consistent these trends are — beyond anything we suspected,” Worm says in a news release.
“This isn’t predicted to happen. This is happening now,” Nicola Beaumont, PhD, of the Plymouth Marine Laboratory, U.K said.
“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,” Beaumont adds.
According to CBS News: But the issue isn’t just having seafood on our plates. Ocean species filter toxins from the water. They protect shorelines. And they reduce the risks of algae blooms such as the red tide.
“A large and increasing proportion of our population lives close to the coast; thus the loss of services such as flood control and waste detoxification can have disastrous consequences,” Worm and colleagues say.
The researchers analyzed data from 32 experiments on different marine environments.
They then analyzed the 1,000-year history of 12 coastal regions around the world, including San Francisco and Chesapeake bays in the U.S., and the Adriatic, Baltic, and North seas in Europe.
Next, they analyzed fishery data from 64 large marine ecosystems.
And finally, they looked at the recovery of 48 protected ocean areas.
Their bottom line: Everything that lives in the ocean is important. The diversity of ocean life is the key to its survival. The areas of the ocean with the most different kinds of life are the healthiest.
But the loss of species isn’t gradual. It’s happening fast — and getting faster, the researchers say.
Worm and colleagues call for sustainable fisheries management, pollution control, habitat maintenance, and the creation of more ocean reserves.
This, they say, isn’t a cost; it’s an investment that will pay off in lower insurance costs, a sustainable fish industry, fewer natural disasters, human health, and more.
“It’s not too late. We can turn this around,” Worm says. “But less than 1% of the global ocean is effectively protected right now.”
Worm and colleagues report their findings in the Nov. 3 issue of Science.
