A drumbeat of recent scientific studies emphasises an increasingly alarming convergence of crises for Earth’s oceans.
The amount of plastic floating in the Pacific Gyre – a massive swirling vortex of rubbish – has increased 100-fold in the past four decades, phytoplankton counts are dropping, over-fishing is causing dramatic decreases in fish populations, decreasing ocean salinity is intensifying weather extremes, and warming oceans are speeding up Antarctic melting.
One warning of humanity’s increasingly deleterious impact on the oceans came from prominent marine biologist Jeremy Jackson of the Scripps Institute of Oceanography.
In a 2008 article published in Proceedings of the National Academy of Sciences, Jackson warned that, without profound and prompt changes in human behaviour, we will cause a “mass extinction in the oceans with unknown ecological and evolutionary consequences”.
The statement might sound extreme, until one considers what science journalist Alanna Mitchell has written about the oceans: “Every tear you cry … ends up back in the ocean system. Every third molecule of carbon dioxide you exhale is absorbed into the ocean. Every second breath you take comes from the oxygen produced by plankton.”
These and other issues will be discussed at the Rio 20 United Nations Conference on Sustainability, which will be held between June 20 and 22 in Rio de Janeiro, Brazil.
But marine biologists, oceanographers, and others who study the seas are telling Al Jazeera of the deepening impact humans are having on the oceans, and, from what they are saying, now is the time to listen.
Plastic, plastic everywhere…
The most obvious impact humans are having on the world’s oceans is pollution. Though it can take myriad forms, pollution is now most shockingly evident in the seas in the form of giant, swirling gyres of plastic.
Scientists recently investigated the North Pacific Subtropical Gyre, known as the “Great Pacific Garbage Patch”, and found an “alarming amount” of refuse, much of it comprising individual pieces of very small size. The eastern section of the spiralling mass, between Hawaii and California, is estimated to be around twice the size of Texas, and is having ecosystem-wide impacts, according to their study released May 8.
Miriam Goldstein, a graduate student researcher at Scripps Institution of Oceanography at University of California San Diego, and the lead author of the study, told Al Jazeera that by adding this amount of plastic to the oceans, humans could be causing large-scale change to the ocean’s ecological system.
“We found eggs on the pieces of plastic, and these were sea-skater [insect] eggs,” Goldstein said. “Sea skaters naturally occur in the gyre and are known to lay their eggs on floating objects. So we found that the amount of eggs being laid had increased with the amount of plastic.”
Goldstein is also concerned by the findings because, “Our work shows there could be potential effects to the ocean ecosystem that we can’t expect or predict. There are five subtropical gyres, one in each ocean basin, and they are natural currents. They are vast areas of the oceans; together they comprise the majority of the area of the oceans. So altering them on a large scale could have unexpected results on all kinds of things.”
The study shows how an increase in pollution, in this case an immense amount of plastic, may have dire consequences for animals across the entire marine food web.
This Scripps study follows another report by colleagues at the institution that showed nine per cent of the fish collected during the trip to study the gyre had plastic waste in their stomachs.
Published in Marine Ecology Progress Series, that study estimated that fish at intermediate ocean depths in the North Pacific Ocean could be ingesting plastic at the staggering rate of 12,000 to 24,000 tonnes per year.
Dr Wallace J Nichols, a research associate at the California Academy of Sciences, told Al Jazeera he finds plastic on every beach he visits across the globe, and added, “Probably every sea turtle on the planet interacts with plastic at some point in its life.”
Jo Royle, a trans-ocean skipper and ocean advocate, has seen the same.
“For 13 years I’ve been crossing oceans,” she told Al Jazeera. “I’ve seen plastic on the coastline of Antarctica, and over the years we’ve noticed plastic becoming more of an issue on remote islands. Over the last seven years we’ve seen it increase dramatically. I can’t remember the last time I’ve been on a beach and not seen plastic.”
Biological oceanographer Dr Debora Iglesias-Rodriguez, with the National Oceanography Centre at Britain’s University of Southampton, is also concerned.
“Marine pollution is a big issue,” she told Al Jazeera. “There is this idea that oceans have unlimited inertia, but nano-particles of plastic getting into marine animals and the food chain are affecting fish fertility rates, and this affects food security and coastal populations. Pollution is having a huge impact on the oceans, and is urgent and needs to be dealt with.”
Dead zones
Another phenomenon afflicting Earth’s oceans are “dead zones”.
While these can be formed by natural causes, climate change, along with human activities and industrial waste, have greatly aggravated the situation.
The US National Oceanographic and Atmospheric Administration released a study showing that rising global temperatures cause oceans to warm, which translates into a decreased capacity to hold oxygen.
The excessive use by industrial agriculture of chemical fertilisers containing phosphorus and nitrogen is the other key factor, since these chemicals encourage the increased development of algae – starving other marine life of oxygen.
The world’s second-largest and most heavily studied human-caused coastal dead zone is in the Gulf of Mexico, a zone caused by massive amounts of the aforementioned chemicals, along with other sources of nitrogen from animal feed, sewage treatment plants, and urban runoff from the Mississippi River flowing into the Gulf.
“All this pollution flows down and in the summer causes huge algae blooms,” Matt Rota, Science and Water Policy Director for the Gulf Restoration Network, told Al Jazeera. “These algae then die and sink to the bottom, where bacteria eat them and deplete the water of oxygen. And the water can’t mix to get more oxygen into it, so sea life suffocates and dies if it’s unable to swim away.”
The Gulf of Mexico dead zone varies in size and shape, but has been steadily increasing in size since it was first measured at 9,774 sq km in 1985. It forms annually at the mouth of the Mississippi River, and spans an area that encompasses the entire coast of Louisiana, and over to Texas.

“The fishermen have never seen anything like this,” Dr Jim Cowan told Al Jazeera. “And in my 20 years working on red snapper, looking at somewhere between 20 and 30,000 fish, I’ve never seen anything like this either.”
Dr Cowan, with Louisiana State University’s Department of Oceanography and Coastal Sciences started hearing about fish with sores and lesions from fishermen in November 2010.
Cowan’s findings replicate those of others living along vast areas of the Gulf Coast that have been impacted by BP’s oil and dispersants.
Gulf of Mexico fishermen, scientists and seafood processors have told Al Jazeera they are finding disturbing numbers of mutated shrimp, crab and fish that they believe are deformed by chemicals released during BP’s 2010 oil disaster.
Along with collapsing fisheries, signs of malignant impact on the regional ecosystem are ominous: horribly mutated shrimp, fish with oozing sores, underdeveloped blue crabs lacking claws, eyeless crabs and shrimp – and interviewees’ fingers point towards BP’s oil pollution disaster as being the cause.
Eyeless shrimp
Tracy Kuhns and her husband Mike Roberts, commercial fishers from Barataria, Louisiana, are finding eyeless shrimp.
“At the height of the last white shrimp season, in September, one of our friends caught 400 pounds of these,” Kuhns told Al Jazeera while showing a sample of the eyeless shrimp.
According to Kuhns, at least 50 per cent of the shrimp caught in that period in Barataria Bay, a popular shrimping area that was heavily impacted by BP’s oil and dispersants, were eyeless. Kuhns added: “Disturbingly, not only do the shrimp lack eyes, they even lack eye sockets.”
“Some shrimpers are catching these out in the open Gulf [of Mexico],” she added, “They are also catching them in Alabama and Mississippi. We are also finding eyeless crabs, crabs with their shells soft instead of hard, full grown crabs that are one-fifth their normal size, clawless crabs, and crabs with shells that don’t have their usual spikes … they look like they’ve been burned off by chemicals.”
On April 20, 2010, BP’s Deepwater Horizon oilrig exploded, and began the release of at least 4.9 million barrels of oil. BP then used at least 1.9 million gallons of toxic Corexit dispersants to sink the oil.
Keath Ladner, a third generation seafood processor in Hancock County, Mississippi, is also disturbed by what he is seeing.
“I’ve seen the brown shrimp catch drop by two-thirds, and so far the white shrimp have been wiped out,” Ladner told Al Jazeera. “The shrimp are immune compromised. We are finding shrimp with tumors on their heads, and are seeing this everyday.”
While on a shrimp boat in Mobile Bay with Sidney Schwartz, the fourth-generation fisherman said that he had seen shrimp with defects on their gills, and “their shells missing around their gills and head”.
“We’ve fished here all our lives and have never seen anything like this,” he added.
Ladner has also seen crates of blue crabs, all of which were lacking at least one of their claws.
Darla Rooks, a lifelong fisherperson from Port Sulfur, Louisiana, told Al Jazeera she is finding crabs “with holes in their shells, shells with all the points burned off so all the spikes on their shells and claws are gone, misshapen shells, and crabs that are dying from within … they are still alive, but you open them up and they smell like they’ve been dead for a week”.
Rooks is also finding eyeless shrimp, shrimp with abnormal growths, female shrimp with their babies still attached to them, and shrimp with oiled gills.
“We also seeing eyeless fish, and fish lacking even eye-sockets, and fish with lesions, fish without covers over their gills, and others with large pink masses hanging off their eyes and gills.”
Rooks, who grew up fishing with her parents, said she had never seen such things in these waters, and her seafood catch last year was “ten per cent what it normally is”.
“I’ve never seen this,” he said, a statement Al Jazeera heard from every scientist, fisherman, and seafood processor we spoke with about the seafood deformities.
Given that the Gulf of Mexico provides more than 40 per cent of all the seafood caught in the continental US, this phenomenon does not bode well for the region, or the country.
BP’s chemicals?
“The dispersants used in BP’s draconian experiment contain solvents, such as petroleum distillates and 2-butoxyethanol. Solvents dissolve oil, grease, and rubber,” Dr Riki Ott, a toxicologist, marine biologist and Exxon Valdez survivor told Al Jazeera. “It should be no surprise that solvents are also notoriously toxic to people, something the medical community has long known”.
The dispersants are known to be mutagenic, a disturbing fact that could be evidenced in the seafood deformities. Shrimp, for example, have a life-cycle short enough that two to three generations have existed since BP’s disaster began, giving the chemicals time to enter the genome.
Pathways of exposure to the dispersants are inhalation, ingestion, skin, and eye contact. Health impacts can include headaches, vomiting, diarrhea, abdominal pains, chest pains, respiratory system damage, skin sensitisation, hypertension, central nervous system depression, neurotoxic effects, cardiac arrhythmia and cardiovascular damage. They are also teratogenic – able to disturb the growth and development of an embryo or fetus – and carcinogenic.
Cowan believes chemicals named polycyclic aromatic hydrocarbons (PAHs), released from BP’s submerged oil, are likely to blame for what he is finding, due to the fact that the fish with lesions he is finding are from “a wide spatial distribution that is spatially coordinated with oil from the Deepwater Horizon, both surface oil and subsurface oil. A lot of the oil that impacted Louisiana was also in subsurface plumes, and we think there is a lot of it remaining on the seafloor”.
Marine scientist Samantha Joye of the University of Georgia published results of her submarine dives around the source area of BP’s oil disaster in the Nature Geoscience journal.
Her evidence showed massive swathes of oil covering the seafloor, including photos of oil-covered bottom dwelling sea creatures.
While showing slides at an American Association for the Advancement of Science annual conference in Washington, Joye said: “This is Macondo oil on the bottom. These are dead organisms because of oil being deposited on their heads.”
Dr Wilma Subra, a chemist and Macarthur Fellow, has conducted tests on seafood and sediment samples along the Gulf for chemicals present in BP’s crude oil and toxic dispersants.
“Tests have shown significant levels of oil pollution in oysters and crabs along the Louisiana coastline,” Subra told Al Jazeera. “We have also found high levels of hydrocarbons in the soil and vegetation.”
According to the US Environmental Protection Agency, PAHs “are a group of semi-volatile organic compounds that are present in crude oil that has spent time in the ocean and eventually reaches shore, and can be formed when oil is burned”.
“The fish are being exposed to PAHs, and I was able to find several references that list the same symptoms in fish after the Exxon Valdez spill, as well as other lab experiments,” explained Cowan. “There was also a paper published by some LSU scientists that PAH exposure has effects on the genome.”
The University of South Florida released the results of a survey whose findings corresponded with Cowan’s: a two to five per cent infection rate in the same oil impact areas, and not just with red snapper, but with more than 20 species of fish with lesions. In many locations, 20 per cent of the fish had lesions, and later sampling expeditions found areas where, alarmingly, 50 per cent of the fish had them.
“I asked a NOAA [National Oceanic and Atmospheric Administration] sampler what percentage of fish they find with sores prior to 2010, and it’s one tenth of one percent,” Cowan said. “Which is what we found prior to 2010 as well. But nothing like we’ve seen with these secondary infections and at this high of rate since the spill.”
“What we think is that it’s attributable to chronic exposure to PAHs released in the process of weathering of oil on the seafloor,” Cowan said. “There’s no other thing we can use to explain this phenomenon. We’ve never seen anything like this before.”

Hundreds of thousands of people living along the US Gulf Coast have hung their economic lives on lawsuits against BP.
Fishermen, in particular, are seeing their way of life threatened with extinction – both from lack of an adequate legal settlement and collapsing fisheries.
One of these people, Greg Perez, an oyster fisherman in the village of Yscloskey, Louisiana, has seen a 75 per cent decrease in the amount of oysters he has been able to catch.
“Since the spill, business has been bad,” he said. “Sales and productivity are down, our state oyster grounds are gone, and we are investing personal money to rebuild oyster reefs, but so far it’s not working.”
Perez, like so many Gulf Coast commercial fisherman, has been fishing all his life. He said those who fish for crab and shrimp are “in trouble too”, and he is suing BP for property damage for destroying his oyster reefs, as well as for his business’ loss of income.
People like Perez make it possible for Louisiana to provide 40 per cent of all the seafood caught in the continental US.
But Louisiana’s seafood industry, valued at about $2.3bn, is now fighting for its life.
‘The shrimp are all dead’
Perez is not alone.
“They said they’d make things right and they never did,” said Nicholas Harris, a fourth-generation oyster fisherman in eastern Louisiana. “Business has been s****y, and BP kept low-balling us with how much money they said they’d give us for compensation, so we got our attorneys involved.”
Harris, like Perez, is suing the oil giant for property damage and loss of income.
His family has a 4,000-acre private lease for oysters, but it was destroyed when the State of Louisiana diverted fresh water from the Mississippi River in a failed attempt to flush BP’s oil from the oyster fishing grounds in his area.
The situation in Mississippi for shrimpers is nearly as grim.
“I was at a BP coastal restoration meeting yesterday and they tried to tell us they searched 6,000 square miles of the seafloor and found no oil, thanks to Mother Nature,” Tuan Dang, a shrimper, told Al Jazeera while standing on a dock full of shrimp boats that would normally be out shrimping this time of year.
Song Vu, a shrimp boat captain for 20 years, has not tried to shrimp for weeks, and is simply hoping that there will be shrimp to catch next season.
His experience during his last shrimping attempts left him depressed.
“The shrimp are all dead,” he told Al Jazeera. “Everything is dead.”

Oil touches nearly every single aspect of the lives of those in the industrialised world. Most of our food, clothing, electronics, hygiene products and transportation simply would not exist without this resource.
There is a reason why oil giants such as ExxonMobile, BP, Total and Royal Dutch Shell, year in and year out, generate more profit than most other companies on the planet.
Our current global economy is based on continual growth, and that growth depends on cheap energy.
“Fossil fuels are roughly 84 per cent of what we use, and oil is 35 per cent of the world’s primary consumption energy,” says David Hughes, a geoscientist who studied Canada’s energy resources for nearly four decades.
Given that oil plays such a critical role in the world’s economy, one would deduce it would be important to know how much is left. Otherwise, the world’s stock markets would be exposed to fossil fuels, which would pose a grave risk to investors facing down a so-called carbon bubble, which could potentially dwarf the housing bubble and current debt crisis.
But acquiring accurate figures on the oil reserves of many of the member states of the Organisation of the Petroleum Exporting Countries (OPEC) is currently impossible, as this remains one of their most highly guarded state secrets.
OPEC, which currently has 12 member countries, established a quota system 25 years ago, so that the size of a country’s oil production quota was based on the size of its reserves.
This caused most Gulf countries to announce that their reserves were much larger than previously, and other OPEC members followed suit, according to Tom Whipple, an energy expert and former CIA analyst.
“Most outside observers believe that the ‘official’ reserves of OPEC members are way overstated,” Whipple, who is also a Post Carbon Institute fellow, told Al Jazeera. “Remember the last increase was in response to the OPEC quota agreement which allowed members to sell oil in proportion to their reserves – the bigger your reserves, the bigger your quota.”
“There have been many scandals over the years from people overstating reserves to make them look richer and more important than they are,” added Whipple.
“The biggest fuss I can recall was in Kuwait about five years ago, when somebody leaked a secret government study that said Kuwait’s reserves were less than half what they had been saying. After much fuss, the government made the whole issue even more secret and refused to answer further questions about the report.”
Oil giant BP produces an annual statistical review containing a spreadsheet that has reported world oil reserves back to 1980.
“I’ve tracked that review for the world and for specific OPEC countries,” geoscientist Hughes told Al Jazeera. “Six countries account for more than 80 per cent of OPEC oil; Saudi [Arabia], Kuwait, Iraq, Iran, United Arab Emirates, and Venezuela, and all six of them jacked up their reserves by nearly 100 per cent between 1984 and 1988.”
According to Hughes, this occurred at roughly the same time these countries changed how they set their production quotas.
“Since then, using Saudi [Arabia] as an example, their reported reserves have been flatlined since 1988, so they’ve not changed their reserves at all, but they produced 96 billion barrels of oil between 1980 and 2010.”
Both Hughes and Whipple, along with other energy experts, believe several OPEC countries are intentionally underreporting their reserves – a situation that will, sooner or later, lead to an economic crash.
State secrets
According to OPEC, “more than 80 per cent of the world’s proven oil reserves are located in OPEC member countries, with the bulk of OPEC oil reserves in the Middle East, amounting to 65 per cent of the OPEC total”.
The group’s website states:
“According to current estimates, OPEC member countries have made significant additions to their oil reserves in recent years … As a result, OPEC’s proven oil reserves currently stand at well above 1,190 billion barrels.”
According to OPEC, its member countries have added 347.2 billion barrels to their total proven crude oil reserves.
OPEC claims to maintain the ability to meet forecasted demand growth “for decades to come” and estimates their “ultimately recoverable reserves (URR)” have increased over time due to technological advances, enhanced recovery methods and new reservoir development.
But according to Hughes, key OPEC oil producers such as Iraq, Kuwait, UAE, and Iran have all likely hit their production peaks, and have been producing at the same levels ever since.
“Iraq[‘s production] is nearly flatline since 1988, and its peak production year was 1979. Kuwait has largely flatlined since 1988 and its peak production was 1972,” he said.
Hughes said that UAE had largely maintained the same level of production since 1988, while having a recent peak in 2006. Iran had a flat production level from 1988 to 2000, with just a slight increase in their reserves, albeit having reached peak production in 1974.
Venezuela, in contrast, nearly doubled its reserves in 2008, and increased them further in 2009, but, like the aforementioned, reached a production peak in 1970 that has not been attained since.
Hence, the leading OPEC countries, which account for two-thirds of the world’s oil reserves, have all passed their peak production points.
“Even Saudi [Arabia] peaked in 2005,” added Hughes, “What that tells you is their rate of production is a lot more important than what they report as their reserves. How can you produce nearly 100bn barrels, like Saudi, and your reserves don’t change at all?”
Hughes then added what he feels is the bottom-line.
“It’s likely those reserves are far lower than they are reporting.”
Dr Ali Samsam Bahktiari, a former official at the National Iranian Oil Company, said in 2006 – just a year before his death – that all the countries in the Middle East vastly overestimated or overstated their reserves.
Complicating matters, demand for oil is forecast to increase dramatically in coming decades.
Dr Fatih Birol, Chief Economist of the International Energy Agency, told The Independent on August 3, 2009:
“Even if demand remained steady, the world would have to find the equivalent of four Saudi Arabias to maintain production, and six Saudi Arabias if it is to keep up with the expected increase in demand between now and 2030. It’s a big challenge in terms of the geology, in terms of the investment and in terms of the geopolitics “
Furthermore, Whipple believes OPEC quotas are no longer relevant.
“Everybody just produces as much oil as they can or [that] is prudent to extract without damaging their oil fields,” he said. “The Saudi and Iranian fields are getting really old and should start to decline in the next decade. The Saudis just announced that they will not be increasing their capacity, except for natural gas. A lot of people are starting to lump in their natural gas production along with their conventional oil. It is called ‘barrels of oil equivalent’. Exxon has been doing this for years, as they pretend their output is increasing.”
Like Whipple, Hughes believes the true oil reserve totals for many OPEC members “are state secrets”.
The mirage of unconventional oil
OPEC also claims: “Technology continues to blur the distinction between conventional and non-conventional oil, of which there is also abundance, as well as with other fossil fuels. We expect the world’s URR [ultimately recoverable resources] to continue to increase in the future. Therefore, the real issue is not reserve availability, but timely deliverability.”
BP refers to URR as “an estimate of the total amount of oil that will ever be recovered and produced”, hence the Canadian tar sands are included.
The tar sands have become infamous due to how dirty the oil is and how energy-intensive it is to extract, along with the massive environmental devastation required in the process of extraction.
Scientific and environmental critics of tar sand extraction also argue that oil companies’ glowing forecasts of how much oil is there, along with how long it will take to extract are fantastic, in a literal sense of the term.
Hughes, whose expertise includes 32 years with the Geological Survey of Canada as both a scientist and research manager, calls the forecasts “exuberant”.
“They were at 1.5 million barrels per day (bpd) in 2010. Industry has tripled the forecasts in 25 years, which would put them at about 4.5mbpd. It’s taken 40 years to get the tar sands to 1.5 million bpd and the surface scar is incredible. I can’t imagine what that would look like if you tripled it.”
Hughes explained the government of Alberta reports 143bn barrels of oil, but “90 per cent of those are too deep to be surface minable. Huge energy inputs are required to get to that. So energy return on investment is going to go down a lot as the tar sands progress. I’ll believe they triple it when I see it … frankly I don’t think it’s possible. This is industry hype they are talking to their shareholders.”
The oil in the tar sands also requires time-consuming construction of more infrastructure to support its extraction and delivery, which, along with the aforementioned factors, lead Hughes to believe the tar sands “can’t be ramped up enough to offset declines of conventional oil”.
