""The ocean is dying, by all accounts – and if so, the food supply along with it. The causes are numerous, and overlapping. And massive numbers of wild animal populations are dying as a result of it.
Natural causes in the environment are partly to blame; so too are the corporations of man; the effects of Fukushima, unleashing untold levels of radiation into the ocean and onto Pacific shores; the cumulative effect of modern chemicals and agricultural waste tainting the water and disrupting reproduction.
A startling new report says in no uncertain terms that the Pacific Ocean off the California coast is turning into a desert. Once full of life, it is now becoming barren, and marine mammals, seabirds and fish are starving as a result. According to Ocean Health:
The waters of the Pacific off the coast of California are a clear, shimmering blue today, so transparent it’s possible to see the sandy bottom below […] clear water is a sign that the ocean is turning into a desert, and the chain reaction that causes that bitter clarity is perhaps most obvious on the beaches of the Golden State, where thousands of emaciated sea lion pups are stranded.
[…]
Over the last three years, the National Oceanic and Atmospheric Administration (NOAA) has noticed a growing number of strandings on the beaches of California and up into the Pacific north-west. In 2013, 1,171 sea lions were stranded, and 2,700 have already stranded in 2015 – a sign that something is seriously wrong, as pups don’t normally wind up on their own until later in the spring and early summer.
“[An unusually large number of sea lions stranding in 2013 was a red flag] there was a food availability problem even before the ocean got warm.”Johnson: This has never happened before… It’s incredible. It’s so unusual, and there’s no really good explanation for it. There’s also a good chance that the problem will continue, said a NOAA research scientist in climatology, Nate Mantua.
Experts blame a lack of food due to unusually warm ocean waters. NOAA declared an El Nino, the weather pattern that warms the Pacific, a few weeks ago. The water is three and a half to six degrees warmer than the average, according to Mantua, because of a lack of north wind on the West Coast. Ordinarily, the north wind drives the current, creating upwelling that brings forth the nutrients that feed the sardines, anchovies and other fish that adult sea lions feed on.
The warm water is likely pushing prime sea lion foods — market squid, sardines and anchovies — further north, forcing the mothers to abandon their pups for up to eight days at a time in search of sustenance.
The pups, scientists believe, are weaning themselves early out of desperation and setting out on their own despite being underweight and ill-prepared to hunt.

“These animals are coming in really desperate. They’re at the end of life. They’re in a crisis … and not all animals are going to make it,” said Keith A. Matassa, executive director at the Pacific Marine Mammal Center, which is currently rehabilitating 115 sea lion pups.
In the storm debris littering a Washington State shoreline, Bonnie Wood saw something grisly: the mangled bodies of dozens of scraggly young seabirds. Walking half a mile along the beach at Twin Harbors State Park on Wednesday, Wood spotted more than 130 carcasses of juvenile Cassin’s auklets—the blue-footed, palm-size victims of what is becoming one of the largest mass die-offs of seabirds ever recorded. “It was so distressing,” recalled Wood, a volunteer who patrols Pacific Northwest beaches looking for dead or stranded birds. “They were just everywhere. Every ten yards we’d find another ten bodies of these sweet little things.”
“This is just massive, massive, unprecedented,” said Julia Parrish, a University of Washington seabird ecologist who oversees the Coastal Observation and Seabird Survey Team (COASST), a program that has tracked West Coast seabird deaths for almost 20 years. “We may be talking about 50,000 to 100,000 deaths. So far.” (source)
100,000 doesn’t necessarily sound large, statistically speaking, but precedent in the history of recorded animal deaths suggests that it is, in fact massive. Even National Geographic is noting that these die off events are “unprecedented.” Warmer water is indicated for much of the starvation faced by many of the dead animals.
Last year, scientists sounded the alarm over the death of millions of star fish, blamed on warmer waters and ‘mystery virus’:
Starfish are dying by the millions up and down the West Coast, leading scientists to warn of the possibility of localized extinction of some species. As the disease spreads, researchers may be zeroing in on a link between warming waters and the rising starfish body count. (source)

The epidemic, which threatens to reshape the coastal food web and change the makeup of tide pools for years to come, appears to be driven by a previously unidentified virus, a team of more than a dozen researchers from Cornell University, UC Santa Cruz, the Monterey Bay Aquarium and other institutions reported Monday.

Changing temperatures in the Pacific Ocean, driven by the natural cycle of gyres over decades, shifts wildlife populations, decimating the populations of species throughout the food chain, proving how fragile the balance of life in the ocean really is.
Commercial fishing for sardines off of Canada’s West Coast is worth an estimated $32 million – but now they are suddenly gone. Back in October, fisherman reported that they came back empty-handed without a single fish after 12 hours of trolling and some $1000 spent on fuel.
Sandy Mazza, for the Daily Breeze, reported a similar phenomenon in central California: “[T]he fickle sardines have been so abundant for so many years – sometimes holding court as the most plentiful fish in coastal waters – that it was a shock when he couldn’t find one of the shiny silver-blue coastal fish all summer, even though this isn’t the first time they’ve vanished.” [emphasis added]
[…]
“Is it El Nino? Pacific Decadal Oscillation? [La] Nina? Long-term climate change? More marine mammals eating sardines? Did they all go to Mexico or farther offshore? We don’t know. We’re pretty sure the overall population has declined. We manage them pretty conservatively because we don’t want to end up with another Cannery Row so, as the population declines, we curb fishing.” said National Oceanic and Atmospheric Administration (NOAA) official Kerry Griffin.

According to a report in the Daily Mail, the worst events have wiped out 90% of animal populations, falling short of extinction, but creating a rupture in food chains and ecosystems.
And environmental factors are known to be a factor, with pollution from chemicals dumped by factories clearly tied to at least 20% of the mass die off events of wildlife populations that have been investigated, and many die offs implicated by a number of overlapping factors. TheDaily Mail reported:
Mass die-offs of certain animals has increased in frequency every year for seven decades, according to a new study.
Researchers found that such events, which can kill more than 90 per cent of a population, are increasing among birds, fish and marine invertebrates.
The reasons for the die-offs are diverse, with effects tied to humans such as environmental contamination accounting for about a fifth of them. ""
