Scientists and economists are concerned that commercial seafood harvesting may end within three decades. A prominent marine research ecologist says that commercial seafood from our oceans could disappear within the next three decades if humans dont take action immediately. Dr. Boris Worm of Dalhousie University in Halifax, Canada warns that the oceans are quickly losing biodiversity and that nearly 30 percent of seafood species that humans consume are already too small to harvest. If the long-term trend continues, there will be little or no seafood available for a sustainable harvest by 2048.
Dr. Worms study was recently published in the journal Science and is an update of a study that was published in 2006. Importantly, the study is of the collapse of commercial catches, not species extinction. Catch collapse means that fish are caught at 10 percent or less of the rate they had been caught historically. Several media outlets have incorrectly stated that the study warns that all seafood will be gone from the ocean. CBS News, for example, reported that the apocalypse has a new date: 2048″ and that the oceans would be empty of fish at that time. To our knowledge, the television network has not issued a retraction. We never said that, says Dr. Worm. We never talked about extinction. We talked about the collapse of the commercial catches.
Still, Worm and his international team of scientists and economists say that catch collapses still paint a grim picture for the ocean and for human health. The accelerated loss of biodiversity, they say, is imperiled by overfishing, pollution, habitat loss and climate change. Saltwater ecosystems, including human populations that depend on them for survival, can be adversely affected by dwindling populations. Harmful algae blooms, coastal flooding and poor water quality can be the results of reduced fish populations. Biodiversity is a finite resource, and we are going to end up with nothing left
if nothing changes, says Worm.
The updated study points out that its not too late to change, however. Areas can be managed for improved biodiversity and recovery is possible, says the study. In areas of the world where action has been taken to protect marine species, there have been notably positive results. The problem is already affecting the U.S. seafood industry. Scientists are urging a moratorium on cold water shrimp harvesting in the Gulf of Maine as rising ocean temperatures are threatening populations of the tiny crustacean. This is the second straight season that researchers have urged that the netting of northern shrimp be halted.

It's all about me...I can share my seafood feasts on-line,,,by drone camera
I learned that from the Millennials

(11,138 posts)True, there is much to be concerned about in our future, but solutions are possible and many of the most difficult problems to fix are ones that will become critical over decades, not years (climate change, oil depletion, etc). It is still the unforeseeable sudden events that concern me most, in addition to worldwide conflict due to poor economic conditions.

Great tuna but really expensive.
