News articles on overfishing
Mongabay.com news articles on overfishing in blog format. Updated regularly.
(02/15/2012) Bangladesh has declared three new sanctuaries to help protect the south Asian river dolphin (Platanista gangetica) in the Sundarbans, the world's largest mangrove forest. Split into two subspecies, the Ganges River dolphin (Platanista gangetica gangetica) and the Irrawaddy River dolphin (Platanista gangetica minor), the new sanctuaries will benefit both. Listed as Endangered by the IUCN Red List, the south Asian freshwater dolphin has disappeared from much of its habitat. Already Asia has its other freshwater dolphin species: the baiji (Lipotes vexillifer) was declared functionally extinct into 2006 after a survey of the Yangtze River failed to find a single individual.
Jellyfish explosion may be natural cycle
(02/06/2012) Evidence that jellyfish are taking over the oceans is currently lacking, according to a new study published in Bioscience. Complied by a number of marine experts, the study found that while jellyfish have been on the rise in some regions it is likely due to a natural cycle of jellyfish populations and not a global boom. Researchers, including a number of marine biologists, have warned for years that jellyfish numbers may be exploding due to human activities, such as overfishing, warmer oceans due to global climate change, and the rise of oxygen-depleted, so-called "dead zones."
Atlantic sturgeon gains protection under the Endangered Species Act
(02/01/2012) The U.S. federal government has listed the massive and bizarre Atlantic sturgeon (Acipenser oxyrinchus) under the protection of the Endangered Species Act (ESA). Historically overfishing decimated the Atlantic sturgeon, while on-going threats include pollution and infrastructure, like dams and bridges that destroy habitat. Fishing for the Atlantic sturgeon has been banned since 1998, they are still caught as bycatch.
Cute animal picture of the day: pygmy killer whale saved after stranding
(01/12/2012) On Tuesday a female pygmy killer whale (Feresa attenuata) was found stranded on Tanjung Aru beach, in the Malaysian state of Sabah on the island of Borneo. After being moved to a swimming enclosure at a local resort for recuperation, the whale was released back into the wild with aid from the Sabah Wildlife Department, marine biologist Lindsay Porter, the local NGO LEAP, and WWF Malaysia.
Bycatch-reducing fish trap wins $20,000
(01/11/2012) An innovative fish trap that allows small non-target fish to escape won a new content by RARE Conservation and National Geographic to fund solutions to overfishing. Developed through studies in Curaçao and Kenya with the Wildlife Conservation Society, the trap has gaps for juvenile fish to swim out of reportedly reducing bycatch by 80 percent. The entry won a $20,000 grant.
World's most expensive tuna
(01/05/2012) A 593 pound Pacific bluefin tuna sold for $735,000 (56.49 million yen) in Tokyo's Tsukiji market today. This beats the previous record price hit last year by over $260,000. Why so expensive? Bluefin tuna, considered the best sashimi and sushi in the world, have been fished to near extinction with the population of the Pacific bluefin the most stable to date.
Seahorses under stress
(11/21/2011) With about 25 million seahorses sold each year, global consumption of seahorses is massive. They’re used in traditional Asian medicine and also sold as curios and aquarium pets. Over the last decade, overexploitation and habitat degradation have prompted declines of between 15 to 70 percent in many seahorse populations. Marine biologist and author Helen Scales notes there is much still unknown about seahorses.
PHOTO: Adorable penguin chicks score their own blog
(11/15/2011) A new blog, dubbed the Real Chicks of Central Park, is allowing visitors an intimate look at eight impossibly-cute penguin chicks. Including video, photos, and interviews the blog is an attempt to raise awareness about penguins. The highlighted chicks include four gentoo penguins (Pygoscelis papua) and four chinstrap penguins (Pygoscelis antarcticus).
US reduces catch limit of 'most important fish in the sea'
(11/15/2011) The Atlantic State Marine Fisheries Commission (ASMFC) has slashed the allowable catch of a tiny fish named menhaden by 37 percent by 2013. Dubbed the 'most important fish in the sea' by author H. Bruce Franklin, the menhaden plays a critical role in marine ecosystems as a food source for larger fish, seabirds, and marine mammals, as well as helping to regulate the marine environment. However, due to overfishing the menhaden fish has dropped 92 percent from its historical population.
Covert Creatures: The Clandestine Lives of Seahorses
(11/15/2011) Seahorses are strange looking creatures, with a horse's head on top of a kangaroo’s pouched belly, bulging, swiveling chameleon eyes, a prehensile monkey tail, color-changing armor and a royal crown, all shrunk down to the size of a chess piece. To marine biologist Helen Scales, these elusive creatures are a perfect symbol of the ocean's biodiversity.
First global assessment finds highest-grossing tunas and billfishes most vulnerable to extinction
(11/09/2011) Sleek, powerful tunas and billfishes that ply the open ocean garner some of the highest prices of any fish. In January, a single bluefin tuna fetched a record $396,000 at a Tokyo auction. Yet wild fish populations pay a still higher price for such exorbitant demand: the threat of extinction. The first assessment of an entire group of commercially valuable marine species found that the most threatened fish are generally the ones reeling in the most money, including bluefin tuna and bigeye tuna.
11 challenges facing 7 billion super-consumers
(10/31/2011) Perhaps the most disconcerting thing about Halloween this year is not the ghouls and goblins taking to the streets, but a baby born somewhere in the world. It's not the baby's or the parent's fault, of course, but this child will become a part of an artificial, but still important, milestone: according to the UN, the Earth's seventh billionth person will be born today. That's seven billion people who require, in the very least, freshwater, food, shelter, medicine, and education. In some parts of the world, they will also have a car, an iPod, a suburban house and yard, pets, computers, a lawn-mower, a microwave, and perhaps a swimming pool. Though rarely addressed directly in policy (and more often than not avoided in polite conversations), the issue of overpopulation is central to environmentally sustainability and human welfare.
Small marine fish need protection too
(10/25/2011) It has long been known that overfishing has decimated some populations of tuna, shark, cod, as well as other big predatory fish; however two recent studies have pointed out that overfishing is also threatening small fish such as anchovies, sardines, mackerel, herring, menhaden, and krill. Although tiny, these species are vital to marine ecosystems since many species higher up on the food chain—from seabirds to marine mammals to big fish—wholly depend on them for survival.
Fishing industry exceeds Atlantic bluefin quota by 141 percent
(10/18/2011) In 2010 the fishing industry exceeded its quota of eastern Atlantic bluefin tuna (Thunnus thynnus) by 141 percent, according to a new analysis by Pew Environment Group. The analysis depends on official data, thereby leaving out the massive black market on Atlantic bluefin tuna.
Poor in Madagascar see fish plundered for foreign consumption
(10/11/2011) A new study warns that overfishing could exacerbate poverty and political stability in one of the world's poorest nations: Madagascar. According to the recent study by the University of British Columbia's Sea Around Us Project and Malagasy NGO Blue Ventures, fish catches in the African island-nation from 1950 to 2008 are actually double the official numbers, with foreign wealthy nations currently taking half the haul.
Marshall Islands creates world's biggest shark park
(10/03/2011) The Republic of the Marshall Islands has created the world's biggest shark reserve: so large that all of Mexico could fit comfortably inside. With new legislation, commercial shark fishing is now completely banned in Marshall Islands' 768,547 square miles (1,990,530 square kilometers) of ocean.
Sowing the seeds to save the Patagonian Sea
(09/07/2011) With wild waters and shores, the Patagonia Sea is home to a great menagerie of marine animals: from penguins to elephants seals, albatrosses to squid, and sea lions to southern right whales. The sea lies at crossroads between more northern latitudes and the cold bitter water of the Southern Ocean, which surround Antarctica. However the region is also a heavy fishing ground, putting pressure on a number of species and imperiling the very ecosystem that supplies the industry. Conservation efforts, spearheaded by marine conservationist Claudio Campagna and colleagues with the Wildlife Conservation Society (WCS), are in the early stages. Campagna, who often writes about the importance of language in the fight for preservation, has pushed to rename the area to focus on its stunning wildlife.
California moves closer to banning shark fin trade
(09/07/2011) California moved a step closer to banning the sale and trade of shark fin with the passage Tuesday of Senate Bill 376. The bill, which passed 25-9, now goes the governor, whose approval would make the ban law. The bill was introduced to the California State Assembly February this year by Paul Fong (D-Cupertino) and Jared Huffman (D-San Rafael).
Honduras protects sharks in all its waters
(06/26/2011) Endangered sharks are finding more sanctuaries. Honduras has announced that commercial shark fishing will be banned from its 92,665 square miles (240,000 square kilometers) of national waters. Honduras says the ban, which follows a moratorium on shark fishing, will bring in tourism revenue and preserve the marine environment.
Ocean prognosis: mass extinction
(06/20/2011) Multiple and converging human impacts on the world's oceans are putting marine species at risk of a mass extinction not seen for millions of years, according to a panel of oceanic experts. The bleak assessment finds that the world's oceans are in a significantly worse state than has been widely recognized, although past reports of this nature have hardly been uplifting. The panel, organized by the International Program on the State of the Ocean (IPSO), found that overfishing, pollution, and climate change are synergistically pummeling oceanic ecosystems in ways not seen during human history. Still, the scientists believe that there is time to turn things around if society recognizes the need to change.
What does Nature give us? A special Earth Day article
(04/22/2011) There is no question that Earth has been a giving planet. Everything humans have needed to survive, and thrive, was provided by the natural world around us: food, water, medicine, materials for shelter, and even natural cycles such as climate and nutrients. Scientists have come to term such gifts 'ecosystem services', however the recognition of such services goes back thousands of years, and perhaps even farther if one accepts the caves paintings at Lascaux as evidence. Yet we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit. The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled. Beyond such physical goods, the natural world provides less tangible, but just as important, gifts in terms of beauty, art, and spirituality.
Giant fish help grow the Amazon rainforest
(04/12/2011) A fruit in the flooded Amazon falls from a tree and plops in the water. Before it can even sink to the floor, a 60-pound monster fish with a voracious appetite gobbles it. Nearly a week later—and miles away—the fish expels its waste, including seeds from the fruit eaten long ago and far away. One fortunate seed floats to a particularly suitable spot and germinates. Many years later the new fruit tree is thriving, while the same monster-fish returns from time-to-time, waiting for another meal to drop from the sky. This process is known as seed-dispersal, and while researchers have studied the seed-dispersal capacity of such species as birds, bats, monkeys, and rodents, one type of animal is often overlooked: fish.
15 conservation issues to watch
(03/14/2011) Deforestation, oil spills, coral acidification: these are just a few examples of ongoing, and well-researched, environmental changes that are imperiling the world's biodiversity. But what issues are on the horizon? At the end of 2010, experts outlined in Trends in Ecology & Evolution 15 issues that may impact conservation efforts this year and beyond, but are not yet widely known. These are issues you may never hear about it again or could dominate tomorrow's environmental headlines. "Our aim was to identify technological advances, environmental changes, novel ecological interactions and changes in society that could have substantial impacts on the conservation of biological diversity […] whether beneficial or detrimental," the authors write in the paper. Experts originally came up with 71 possible issues and then whittled it down to the 15 most important—and least known.
Mitsubishi and Walmart agree to clean up fish sourcing practices
(03/09/2011) Two big players in seafood today announced that they are changing the way their fish are caught. Mitsubishi, which owns the UK's most popular brand for tuna in a tin, Princes, and Walmart, which owns Asda, have agreed to stop buying from fishermen who use purse seines fishing in conjunction with fish aggregating devices (FADs) by 2014. These methods have been blamed in part for the vast overfishing of the world's tuna and helping to decimate other species, such as sharks and rays, as bycatch.
Coral crisis: 75% of the world's coral reefs in danger
(02/23/2011) Marine scientists have been warning for years that coral reefs, the most biodiverse ecosystems in the ocean, are facing grave peril. But a new comprehensive analysis by the World Resources Institute (WRI) along with twenty-five partners ups the ante, finding that 75% of the world's coral reefs are threatened by local and global impacts, including climate change. An updating of a 1996 report, the new analysis found that threats had increased on 30% of the world's reefs. Clearly conservation efforts during the past decade have failed to save reefs on a large-scale.
Arctic fish catch vastly underreported (by hundreds of thousands of metric tons) for 5 decades
(02/07/2011) From 1950 to 2006 the United Nation Food and Agriculture Agency (FAO) estimated that 12,700 metric tons of fish were caught in the Arctic, giving the impression that the Arctic was a still-pristine ecosystem, remaining underexploited by the world's fisheries. However, a recent study by the University of British Colombia Fisheries Center and Department of Earth and Ocean Sciences throws cold water on this widespread belief. According to the study, published in Polar Biology, the total Arctic catch from 1950 to 2006 is likely to have been nearly a million metric tons, almost 75 times the FAO's official record.
The ocean crisis: hope in troubled waters, an interview with Carl Safina
(02/07/2011) Being compared—by more than one reviewer—to Henry Thoreau and Rachel Carson would make any nature writer's day. But add in effusive reviews that compare one to a jazz musician, Ernest Hemingway, and Charles Darwin, and you have a sense of the praise heaped on Carl Safina for his newest work, The View from Lazy Point: A Natural Year in an Unnatural World. Like Safina's other books, The View from Lazy Point focuses on the beauty, poetry, and crisis of the world's oceans and its hundreds-of-thousands of unique inhabitants. Taking the reader on a journey around the world—the Arctic, Antarctic, and the tropics—Safina always returns home to take in the view, and write about the wildlife of his home, i.e. Lazy Point, on Long Island. While Safina's newest book addresses the many ways in which the ocean is being degraded, depleted, and ultimately imperiled as a living ecosystem (such as overfishing and climate change) it also tweezes out stories of hope by focusing on how single animals survive, and in turn how nature survives in an increasingly human world. However, what makes Safina's work different than most nature writing is his ability to move seamlessly from contemporary practical problems to the age-old philosophical underpinnings that got us here. By doing so, he points a way forward.
Record high fish consumption keeps populations imperiled
(02/01/2011) More people than ever are eating more fish than ever, according to a new report by the United Nations covering the year 2008. At the same time, fish populations in the world's oceans continue to decline threatening marine ecosystems, food security, and the fishing industry itself.
Italy and Panama continue illegal fishing, says new report
(01/15/2011) On Wednesday, the National Oceanic and Atmospheric Administration (NOAA) issued its biennial report identifying six countries whose fisheries have been engaged in illegal, unreported, or unregulated (IUU) fishing during the past two years. The report comes at a time when one-fifth of reported fish catches worldwide are caught illegally and commercial fishing has led to a global fish stock overexploitation of an estimated 80 percent.
Japanese firm is deadliest for marine life, says Greenpeace
(01/10/2011) Greenpeace has ranked the canned tuna corporation Princes as the most environmentally damaging tuna brand in the U.K., citing that the Japanese company uses destructive fishing methods and that its claims of sustainability are blatantly untrue.
Bluefin tuna gets record price ($396,000) at Japanese auction
(01/06/2011) On Tuesday, a 752-pound Pacific bluefin tuna was sold at Japanese auction for the highest price ever received for raw seafood - $396,000. The price tops the previous record by more than $100,000 and comes at a time when tuna populations around the world are experiencing precipitous declines.
Sustainability of Antarctic toothfish fishery, legitimacy of Marine Stewardship Council called into question
(01/05/2011) In November of 2010, the Antarctic toothfish fishery was deemed sustainable by the Marine Stewardship Council. This certification goes against the advice of many marine scientists who claim that insufficient research has been done to determine the full impact of commercial fishing on this enigmatic species.
Fisheries commissions' ability to manage diminishing tuna stocks called into question
(12/31/2010) During a meeting earlier this month, the Western and Central Pacific Fisheries Commission (WCPFC) disregarded appeals from the EU and Japan, as well as from Commission scientists, calling for a substantial and immediate reduction in catch rates of bigeye and yellowfin tuna in response to diminished stocks. An earlier meeting of the International Commission for the Conservation of Atlantic Tunas (ICCAT) resulted in only cosmetic cuts to Atlantic bluefin quotas, calling into question the ability of the global system of Regional Fisheries Management Organizations (RFMOs) to prevent overfishing.
Growing Atlantic dead zone shrinks habitat for billfish and tuna, may lead to over-harvest
(12/29/2010) A dead zone off the coast of West Africa is reducing the amount of available habitat for Atlantic tuna and billfish species, reports the National Oceanic and Atmospheric Administration in a study published in Fisheries Oceanography. The zone is growing due to global warming and is expected to cause over-harvest of tuna and billfish as the fish seek higher levels of oxygen in areas with greater fisheries activity.
UN report urges fishing subsidy reform
(12/28/2010) The continuation of government fishing subsidies is damaging to the world's oceans and should be halted, states the United Nations Environment Programme in a new publication that calls for subsidy reform. The report, Fisheries Subsidies, Sustainable Development and the WTO, finds that in many cases the subsidies encourage fishing in areas whose ecosystems are already overtaxed.
World has run out of fishing grounds
(12/06/2010) The world's oceans can no longer accommodate fisheries expansion, confirms a study conducted by joint effort between the University of British Columbia and the National Geographic Society. The study is the first of its kind to analyze the geographic expansion of global fisheries. Published in the journal PLoS ONE, the study lends additional credence to reports that current fishing practices are unsustainable. Researchers holistically determined the ecological footprint of commercial fisheries by looking at primary production—the tiny organisms that make up the bottom of the food chain—and calculating the amount necessary to support current fishing yields around the world from 1950 to 2005. The study finds that the amount of primary production required to maintain commercial fishing at current levels far exceeds that which exists.
Thousands pledge to boycott restaurants serving bluefin tuna
(12/01/2010) So far over 14,000 people have pledged to boycott eating bluefin tuna or visiting any restaurant that serves the imperiled species. The boycott, begun by US-conservation organization Center for Biological Diversity (CBD), is striving to raise awareness about a species that many scientists say is being fished to the brink of extinction.
'Environmental and social aggression': oil exploration threatens award-winning marine protected area
(12/01/2010) The Seaflower Marine Protected Area (MPA), which recently won top honors at the Convention on Biological Diversity (CBD) in Japan, is now under threat by planned oil exploration in the region, according to the Providence Foundation which is devoted to protecting the area. Proposed blocs for exploration by the Colombian government lie in the North Cays adjacent to the park, and perhaps even inside MPA boundaries. Spreading over 65,000 square kilometers (6.5 million hectares), Seaflower MPA lies within the Colombian Caribbean department known as the Archipelago of San Andres, Old Providence and Santa Catalina. This richly diverse Archipelago is home to a known 57 coral species, over 400 fish, and some 150 birds, as well as the ethnic and cultural minority: the Raizal people. The prospect of massive infrastructure or, even worse, oil spills in the area could devastate the park and locals' livelihoods.
Environmentalists: fishing quota could be death sentence for bluefin tuna
(11/28/2010) Once again, the International Commission for the Conservation of Atlantic Tuna (ICCAT) has flouted warnings from conservationists, evidence from scientists, and even recommendations from the European Commissioner Fisheries and Maritime Affairs in its most recent fishing quota for the Atlantic bluefin tuna. Meeting last week in Paris, ICCAT agreed to a 2011 fishing quota of 12,900 metric tons, 600 less than this year's quota. Yet, environmentalists from a wide-range of organizations have been warning for years that without a moratorium on bluefin fishing—or at least a drastic reduction in quotas—the species is at risk of extinction. ICCAT's own scientists say that the current quota gives the species a 70% chance of recovery.
Beyond gloom: solutions to the global coral reef decline
(11/10/2010) The world's coral reefs are in trouble. Due to a variety of factors—including ocean acidification, warming temperatures from climate change, overfishing, and pollution—coral cover has decline by approximately 125,000 square kilometers in the past 50 or so years. This has caused some marine biologists, like Charlie Veron, Former Chief Scientist of the Australian Institute of Marine Science, to predict that coral reefs will be largely extinguished within a century. This year alone, large-scale coral bleaching events, whereby coral lose their symbiotic protozoa and become prone to disease and mortality, were seen off the coasts of Indonesia, the Philippines, and some Caribbean islands. However a new paper in Trends in Ecology and Evolution attempts to dispel the gloom over coral reefs by pointing to strategies, and even some successes, to save them.
World needs to protect 32 million square kilometers of ocean in two years
(10/20/2010) According to goals set in 2002 by the Convention on Biological Diversity (CBD) and the World Summit on Sustainable Development, nations must spend the next two years catching-up on creating ocean reserve. Currently, about 1.17 percent of the ocean is under some form of protection, but the 2002 goal was 10 percent by 2012. That means protecting over 32.5 million square kilometers, of the ocean twice the size of Russia. According to a recent report, Global Ocean Protection by the Nature Conservancy, not only is the world failing on its goals to protect a significant portion of the ocean, it's also failing to protect 10 percent of various marine ecosystems.
Colombian marine reserve receives top honors at global biodiversity meeting
(10/20/2010) Coralina, a Colombian government agency that established the Seaflower Marine Protected Area (MPA) with local community involvement, is being heralded today by the Convention on Biological Diversity (CBD) in Nagoya, Japan. Proving that conservation and sustainable economic opportunities can go hand-in-hand, Coralina was instrumental in creating a marine park that protects nearly 200 endangered species while providing sustainable jobs for local people in the Western Caribbean Colombian department of Archipelago of San Andrés, Old Providence and Santa Catalina. Coralina was one of over 1,000 agencies and organizations that are apart of the Countdown 2010 program, which highlights effective action to save species at the CBD.
Already Critically Endangered, bluefin tuna hit hard by BP oil disaster
(10/19/2010) Using satellite data from the European Space Agency, researchers estimate that over 20% of juvenile Atlantic bluefin tuna in the Gulf of Mexico were killed by the BP oil spill. Although that percentage may not seem catastrophic, the losses are on top of an 82% decline in the overall population over the past three decades due to overfishing. The population plunge has pushed the International Union for the Conservation of Nature (IUCN) to categorize the fish as Critically Endangered, its highest rating before extinction.
Marine managed areas help reverse declining fisheries, create sustainable livelihoods
(09/16/2010) Marine managed areas in developing countries can help reverse declining fisheries while generating long-term benefits for communities, according to a series of reports released by Conservation International (CI). The reports, informed by more than 50 studies and 100 scientists in 23 countries around the world since 2005, evaluate the role of marine managed areas (MMAs) in maintaining ocean health, assess the link between sustainable ocean use and human well-being, and architect what it takes to successfully implement MMAs.
Shark attack victims: save sharks!
(09/13/2010) Shark attack survivors urged the United Nations to take measures to protect sharks, which are increasingly threatened by unsustainable fishing practices.
Coral reef survival depends on the super small, an interview with Forest Rohwer
(08/30/2010) If you take a teaspoon and dip it into the ocean what will you have? Some drops of lifeless water? Only a few decades ago this is what scientists would have said, however, the development of increasingly powerful microscopes have shown us a world long unknown, which has vital importance for the survival of one of the world's most threatened and most treasured ecosystems: coral reefs. A single milliliter of water is now known to contain at least a million living microbes, i.e. organisms too small to see without a microscope. After discovering their super-abundant presence, researchers are now beginning to uncover how these incredibly tiny life-forms shape the fate of the world's coral reefs.
The biology and conservation of declining coral reefs, an interview with Kristian Teleki
(08/15/2010) Coral reefs are often considered the "rainforests of the sea" because of their amazing biodiversity. In fact, coral reefs are one of the most diverse ecosystems on earth. It is not unusual for a reef to have several hundred species of snails, sixty species of corals, and several hundred species of fish. While they comprise under 1% of the world’s ocean surface, one-quarter of all marine species call coral reefs their home. Fish, mollusks, sea stars, sea urchins, and more depend on this important ecosystem, and humans do too. Coral reefs supply important goods and services–from shoreline protection to tourism and fisheries–which by some estimates are worth $375 billion a year.
Nation's wealth does not guarantee green practices
(08/11/2010) Developing countries are not the only ones that could benefit from a little environmental support. Wealthier countries may need to 'know themselves' and address these issues at home too. According to a recent study in the open access journal PLoS ONE, wealth may be the most important factor determining a country’s environmental impact. The team had originally planned to study "country-level environmental performance and human health issues," lead author Corey Bradshaw, Director of Ecological Modeling and professor at the University of Adelaide, told mongabay.com. Once they began looking at the available indexes, however, they saw the need for a purely environmental analysis.
Backbone of marine food chain in alarming decline
(07/28/2010) Tiny marine algae, known as phytoplankton, are the backbone of the marine food chain, yet a new study in Nature has found that this backbone is disintegrating. Researchers discovered that since 1950 phytoplankton has declined by approximately 40 percent across the Northern Hemisphere, a decline that corresponds to warming waters due to climate change. Given that phytoplankton feed the oceans' abundance all the way up the food chain—from zooplankton to fish to seabird to sharks to humans—the decline has likely impacted the very structure of the ocean.
In the midst of marine collapse will we save our last ocean?
(07/05/2010) Imagine an ocean untouched by oil spills: a sea free of pollution, invasive species, dead zones, and over-exploitation; waters where marine animals exist in natural abundance and play ecological roles undimmed by mankind. Such a place may sound impossible in today's largely depleted oceans, but it exists: only discovered in 1841, the Ross Sea spreads over nearly a million kilometers adjacent to the Antarctic continent. Here killer whales, penguins, sea birds, whales, and giant fish all thrive. However, even with its status as the world's 'last ocean', the Ross Sea has not escaped human impact. Over the last 15 years commercial fisheries have begun to catch one of its most important species in the ecosystem to serve them up on the dinner plates of the wealthy.
