							<![CDATA[Mangrove forests could help sequester more than five million metric tons of nitrogen pollution from coastal ecosystems across the Earth if they are restored and protected, a recent study found. Nitrogen pollution typically comes from synthetic fertilizers largely used in agriculture or from human waste seeping into water sources. Nitrogen is an essential nutrient for life, but in excess it fuels algal blooms, leaving water murky and with a foul smell. In the worst cases, the death of the algal blooms can starve ecosystems of oxygen, leaving large dead zones that can kill fish and other aquatic life. Researchers analyzed data on nitrogen removal by mangroves across the world and estimated mangroves currently sequester around 870,000 metric tons of nitrogen every year. The study found that if mangroves are protected and restored, this number could increase to more than 5 million metric tons a year. This ecosystem service mangroves provide is worth over $8 billion annually, the researchers estimated. “Mangrove forests represent a powerful and undervalued natural mitigation solution for nitrogen pollution,” study co-authors Ziyan Wang and Benoit Thibodeau wrote. Wang and Thibodeau argued nitrogen removal should be treated similarly to carbon storage and suggested creating a market for blue nitrogen credits to help finance the climate solution. They estimated nitrogen credits would be priced at around $10,000 per metric ton, based on previous projects. The total value of a nitrogen removal market would far exceed that of carbon storage in mangrove ecosystems, according to the study.

								<![CDATA[- The creation of synthetic fertilizers in the early 20th century was a turning point in human history, enabling an increase in crop yields and causing a population boom.<br />- But the overuse of nitrogen and phosphorus from those fertilizers is causing an environmental crisis, as algae blooms and oceanic “dead zones” grow in scale and frequency.<br />- Of the nine “planetary boundaries” that scientists say we must not cross in order to sustain human life, the boundary associated with nitrogen and phosphorus waste has been far surpassed, putting Earth’s operating system at risk.<br />- Global policymakers are beginning to slowly recognize the scale of the problem, as climate change threatens to make it worse. Absent major reforms to agribusiness practices, scientists are aiming to convince the world to reduce waste.<br />]]>

							<![CDATA[On an average sunny day, Guatemala’s Lake Atitlán is a stunning vista of turquoise water and sky. Ringed by towering volcanos, the lake is a UNESCO World Heritage site; below its waves lie sunken ruins that were once used for worship and ceremony by the Mayan communities that have thrived here for thousands of years. But one morning in 2009, people living in those communities woke up to a shock. Vast swaths of the lake were sickly green. A film of foul-smelling scum was drifting on its surface, washing ashore, and swirling in the coves where people bathe and catch fish. Atitlán had been overrun by cyanobacteria, or as it’s more commonly known, blue-green algae. The outbreak was massive, covering 40% of the lake’s surface; big enough to be seen from space. It was the first time a blue-green algae outbreak that size had been recorded at the lake, but it wouldn’t be the last. In 2015, another extensive bloom chased away tourists, a vital part of the local economy, and now, algal blooms are a semiconstant health threat for the lake’s Indigenous residents. The surface of Guatemala’s Lake Atitlán is normally a sweeping, fluorescent blue vista. The lake is a vital part of the local economy and the Indigenous residents also depend on it for water.

							<![CDATA[On today’s episode we feature a conversation with iconic Canadian scientist, author, television presenter, and activist David Suzuki. Suzuki is a biologist by training and a former professor of genetics who’s just as well known for his outspoken views on the need to protect nature. Suzuki is the author or co-author of more than 50 books and the host of the long-running science program The Nature of Things. He’s also the founder of the David Suzuki Foundation and the Blue Dot Movement, the latter of which aims to enshrine the right to a healthy environment in the Canadian Constitution. Mongabay interviewed Suzuki last year about the Blue Dot Movement, and we thought now, at the start of 2018, would be a great time to check in with him about what progress has been made, what environmental issues he thinks are most pressing as we forge ahead into the new year, and his plans to convene a gathering of First Nations keepers of traditional ecological knowledge with Western scientists.* Here’s this episode’s top news: Peru declares a huge new national park in the Amazon Study: Amazon dams are disrupting ecologically vital flood pulses Global warming, pollution supersize the oceans’ oxygen-depleted dead zones Belize imposes offshore oil moratorium to protect reefs There’s a new member of the lemur family You can subscribe to the Mongabay Newscast on Android, Google Play, iTunes, Stitcher, TuneIn, RSS and via Spotify.

								<![CDATA[- Large areas of the world’s oceans are rapidly losing oxygen as a result of global warming and pollution, threatening marine ecosystems and the hundreds of millions of people who depend on them, according to a new study.<br />- The scientists expect deoxygenation to increase well beyond these so-called dead zones as long as human-driven global warming continues.<br />- Despite the grim outlook for the oceans, the researchers suggest that cutting fossil fuel use and protecting vulnerable marine life could tackle the problem.<br />]]>

							<![CDATA[Vast swaths of the world’s oceans are turning into “dead zones” as global warming and pollution strips them of oxygen, threatening marine life on a massive scale, a new study shows. The analysis, which reviews the major research on ocean oxygen loss, is the first to investigate the causes, consequences and solutions to low oxygen concentrations in the open oceans and coastal waters. Over the past 50 years, zones in the open ocean with zero oxygen have more than quadrupled, or increased by over 4.5 million square kilometers (1.7 million square miles) — an area roughly the size of the European Union — according to the study published Jan. 2 in the journal Science. It added that in coastal water bodies, including estuaries and seas, the number of low-oxygen sites have soared about tenfold from fewer than 50 in 1950. In ocean waters, oxygen levels are also falling, with 77 billion tons being lost since 1950. This map indicates coastal sites where anthropogenic nutrients have exacerbated or caused water oxygen concentrations to decline to less than 2 milligrams per liter (red dots), as well as ocean oxygen-minimum zones at depths of 300 meters, or  980 feet (blue regions). Map created from data provided by Robert Diaz, updated by members of the GO2NE network, and downloaded from the World Ocean Atlas 2009. The analysis indicated that deoxygenation in the open ocean was caused by global warming as a result of increased greenhouse gas emissions, as warmer water holds less oxygen.

							<![CDATA[Last week, scientists from the National Oceanic and Atmospheric Administration (NOAA) announced the largest-ever recorded low-oxygen &#8220;dead zone&#8221; in the Gulf of Mexico. At 22,730 square kilometers (8,776 square miles) the area is the size of the U.S. state of New Jersey. The dead zone is primarily the result of nutrient pollution that stimulates massive blooms of algae. When this algae decomposes, oxygen levels drop below levels needed by many Gulf species to survive or develop normally; scientists refer to low-oxygen conditions as hypoxia. &#8220;The dead zone adversely affects organisms in a number of ways,&#8221; said Robert Magnien, director of NOAA&#8217;s Center for Sponsored Coastal Ocean Research. &#8220;It reduces available habitat for fish and shrimp and reduces their food supply. Exposure to hypoxia can also directly reduce growth and reproduction.&#8221; At 22,730 square kilometers (8,776 square miles), this year&#8217;s dead zone in the Gulf of Mexico is the largest ever measured. Image courtesy of N. Rabalais, LSU/LUMCON. This can have knock-on effects for local economies if hypoxia kills off or changes commercially important populations. &#8220;The fear is that if the size of the dead zone remains at its current level or increases in the future, there will likely be further reductions in the abundance of key commercial and recreational species,&#8221; Magnien told Mongabay. A study by Duke University found shrimp grow more slowly in the dead zone. This led to a deficit in large shrimp, lower prices for small ones and consequential economic changes to the Gulf brown shrimp fishery.&hellip;This article was originally published on <a href="https://news.mongabay.com/2017/08/noaa-announces-largest-ever-gulf-of-mexico-dead-zone/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Two scientists are calling on researchers, NGOs, and governments to begin studying the impact of burning forests and peatlands in Indonesia on the already-threatened marine ecosystems of Southeast Asia. Every year, Indonesian farmers set forests, vegetation, and peatlands alight to clear them for agriculture, often palm oil, and pulp and paper plantations. Not only do these practices destroy hugely-diverse tropical forests, but the resulting haze spreads to many parts of Southeast Asia, threatening regional health and impacting economies. Now, a new paper argues that the sinister impacts of Indonesia&#8217;s burning may extend as far as the oceans. &#8220;Biomass burning in Indonesia has intensified in frequency and severity since the 1970s&#8230;In June 2013, regional air pollution indices reached record highs, with values deemed hazardous in Singapore, Indonesia and Malaysia, prompting some affected areas to declare states of emergency,&#8221; the researchers, Zeehan Jaafar with the National University of Singapore and Tse-Lynn Loh with the John G. Shedd Aquarium, write in a new opinion paper in Global Change Biology. Last year&#8217;s crisis lead to global press coverage, finger-pointing, and high level meetings between numerous governments in the region. But the problem remains: just last month NASA satellite recorded hundreds of hotspots, i.e. fires, on the Indonesian island of Sumatra. While the health, economic, and land-based environmental issues of this burning has been well-documented, the impact on marine ecosystems has been almost wholly ignored. This natural-color satellite image was collected by the Moderate Resolution Imaging Spectroradiometer aboard the Terra satellite on Feb. 28, 2014.&hellip;This article was originally published on <a href="https://news.mongabay.com/2014/03/does-haze-from-burning-forests-affect-marine-life/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[From massive hotel development through the agriculture industry, humans are destroying the second largest barrier reef in the world: the Mesoamerican Reef. Although global climate change and its effects on reefs via warming and acidification of coastal waters have made recent headlines, local human activities may destroy certain ecosystems before climate change has a chance to do it. The harmful effects of mining, agriculture, commercial development, and fishing in coastal regions have already damaged more than two-thirds of reefs across the Caribbean, in addition to worsening the negative effects of climate change. A recent evaluation by the Healthy Reefs Initiative (HRI, www.healthyreefs.org) of the Mesoamerican Reef (MAR), which runs continuously for over 1,000 km, from north of Mexico&#8217;s Yucatan Peninsula south to Honduras, highlights the combination of locally-grown threats to this iconic ecosystem. Figure 1. The Mesoamerican Reef with 193 sites coded by their Simplified Integrated Reef Health Index (SIRHI) score. Orange and red sites have poor or critically poor reef health. Map from Healthy Reefs Initiative. Coral reefs: valuable yet complex systems Coral reefs are unique ecosystems, which provide human communities with a suite of irreplaceable benefits. They feed millions of people worldwide, buffer harbors and shorelines from storm waves, restock fisheries by sheltering juvenile fish, and attract snorkeling and SCUBA-diving tourists to coastal regions. They even supply much of the sand seen on the region&#8217;s beaches.

							<![CDATA[Corn growing in Colombia. Photo by: Rhett A. Butler. In general, industrial agriculture beats organic farming in yields, according to a comprehensive new study in Nature. The study adds new data to the sometimes heated debate of organic versus conventional farming. Proponents of organic farming argue that these practices are environmentally friendly, sustainable over the long-term, and provide a number of social goods. However, critics argue that organic farming requires more land, thereby increasing global deforestation, which offsets any other environmental benefits of organic food production. At stake is whether organic or conventional is capable of feeding the world&#8217;s seven billion people (and rising), including increasing demand for energy-intensive foods like meat in the developing world. After weeding out problematic research on organic versus conventional agricultural, researchers with the University of Minnesota and McGill University looked at 66 studies on 34 different crops. They found that conventional farming currently beats organic agriculture in yields by 25 percent. However, that simple statistic does not capture the full picture: yields varied widely between types of crops and growing methods. &#8220;For some crops, like many fruits and some legumes (e.g., chickpeas or beans), organic farms nearly match the yield performance of their conventional counterparts, co-author Jonathan Foley, director of the Institute on the Environment, explained to mongabay.com. For example, when looking at rain-fed legumes, the study found that organic yields were only 5 percent behind conventional, and organic fruits were just 3 percent behind. &#8220;But for other crops, like our major cereals and&hellip;This article was originally published on <a href="https://news.mongabay.com/2012/04/organic-yields-lag-behind-industrial-farming-but-thats-not-the-whole-story/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[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 &#8220;dead zones.&#8221; &#8220;Clearly, there are areas where jellyfish have increased&#8212;the situation with the Giant Jellyfish in Japan is a classic example,&#8221; says lead author Rob Condon, marine scientist at the Dauphin Island Sea Lab (DISL) in the U.S. &#8220;But there are also areas where jellyfish have decreased, or fluctuate over the decadal periods.&#8221; Looking over data going back to 1790, researchers did not see any long-term upswing in jellyfish populations, but rather boom-and-bust cycles that have been occurring for centuries. &#8220;The past period of rise was in the mid-90s to about 2005, and that&#8217;s when all the papers claiming there was a global rise came out,&#8221; Carlos Duarte, director of the Oceans Institute at the University of Western Australia, told the Australian Broadcasting Corporation (ABC). &#8220;So in fact there was a little bit of support for that because there was more a general rise than the previous decade, but this is not unprecedented.

One day many of the world&#8217;s marine species may only be found in aquariums, if at all, such as this green sea anemone in the Monterey Bay Aquarium. Photo by: Rhett A. Butler. Multiple and converging human impacts on the world&#8217;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&#8217;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. &#8220;The findings are shocking,&#8221; Alex Rogers, IPSO&#8217;s scientific director and professor of conservation biology at Oxford University, said in a press release. &#8220;As we considered the cumulative effect of what humankind does to the oceans, the implications became far worse than we had individually realized. We&#8217;ve sat in one forum and spoken to each other about what we&#8217;re seeing, and we&#8217;ve ended up with a picture showing that almost right across the board we&#8217;re seeing changes that are happening faster than we&#8217;d thought, or in ways that we didn&#8217;t expect to see&hellip;This article was originally published on <a href="https://news.mongabay.com/2011/06/ocean-prognosis-mass-extinction/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Flooding in the Midwest is likely to cause the largest-ever dead zone in the Gulf of Mexico, reports the National Oceanic and Atmospheric Administration (NOAA). NOAA-supported scientists from three universities &#8212; the Louisiana Universities Marine Consortium, Louisiana State University and the University of Michigan &#8212; predict the area of low oxygen in the Gulf will measure between 8,500 and 9,421 square miles, an area roughly the size of New Hampshire. The largest Gulf dead zone ever measured since record-keeping began in 1985 occurred in 2002 and encompassed more than 8,400 square miles. The average Gulf dead zone over the past five years. is 6,000 square miles. Scientists believe this year&#8217;s hypoxic zone will be especially large due to agricultural run-off from flooded farmlands. &#8220;Hypoxia is caused by excessive nutrient pollution, often from human activities such as agriculture that results in too little oxygen to support most marine life in bottom and near-bottom water,&#8221; says NOAA. The dead zone typically triggers large-scale die-offs of commercially-valuable sea life. Nutrient pollution in the Mississippi has been exacerbated by subsidies to boost corn ethanol production. Earlier this week the Senate voted to end support of corn ethanol, which has cost U.S. taxpayers $30 billion since 1980.

							<![CDATA[Prosperity without Growth: Economics for a Finite Planet challenges us to imaging a world where growth and unmitigated consumption do not equal development. In fact, as clearly described throughout, countries with unmitigated consumption are the underdeveloped countries of the 21st Century expanding our global ecological debt at the expense of countries who are more sophisticated in their development practices with similar prosperity levels while incurring less &#8220;national&#8221; ecological debt. The development of natural capital by enhancing ecological value and then describing an economic value to this enhancement—or delta—is the challenge of the 21st Century. By expanding upon payments for ecosystem services (PES) systems allowing us to pay for improved water quality, biodiversity enhancement, and biogenic carbon sequestration, we are challenging traditional economics that often viewed natural capital as an unlimited resource base. 21st Century development is not unconstrained economic expansion. 21st Century development is bounded economic efficiency focusing on first minimizing negative ecological impact and second enhancing positive ecological impact. As repeatedly demonstrated in throughout the book, if we do not engage in a 21st Century development pattern leading to a biodiversity, ecological, and carbon positive economy, we shall tremendous economic collapse globally. Our current labyrinth of ecological debt is already causing substantial economic harm to our economies. We only have to consider the concepts eloquently described by Tim Jackson in the framework of the devastating flooding in the Mississippi River Valley this spring in the United States.

							<![CDATA[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 rising water temperatures 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. Dead zones are areas of the ocean which are too low in oxygen to support many marine species. There are about 400 of these &#8220;hypoxic&#8221; regions throughout the world, many caused by human activities. Perhaps the most notorious, the New Jersey-size dead zone in the Gulf of Mexico is caused by fertilizer runoff released by the Mississippi which encourages oxygen-depleting algae to proliferate out of control. Another dead zone was discovered in 2007. It occurs off the coast of Texas, where the Brazos river empties into the Gulf. Dead zones can also be caused by climate change. Increases in ocean temperature can change the course of currents, isolating certain areas from influxes of deeper, colder water. As the water in the area sits, it warms and releases its oxygen, making it inhospitable to many aquatic species. Three major dead zones are known to have been caused by climate change: one off the coast of Chile and Peru, one off the east coast of Africa, and another off of Africa&#8217;s west coast. A new dead zone was reported off the US west&hellip;This article was originally published on <a href="https://news.mongabay.com/2010/12/growing-atlantic-dead-zone-shrinks-habitat-for-billfish-and-tuna-may-lead-to-over-harvest/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[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 these microscopic plants feed the oceans&#8217; 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. &#8220;Phytoplankton are a critical part of our planetary life support system. They produce half of the oxygen we breathe, draw down surface CO2, and ultimately support all of our fisheries. An ocean with less phytoplankton will function differently, and this has to be accounted for in our management efforts,&#8221; explains co-author and associate professor, Boris Worm, from Dalhousie University. Employing both historical records and contemporary data, researchers were able to compile a database with half a million observations in order to recreate the oceans&#8217; phytoplankton populations going all the way back to 1899. In doing so they discovered a continuing decline of around 1 percent of the global average every year. Since the declines were linked to rising temperatures, researchers say that warmer oceans restrict the abundance of nutrients delivered from the deep to the surface. Since such nutrients are essential for phytoplankton production, less nutrients equals less phytoplankton. &#8220;Climate-driven phytoplankton declines are another important dimension of global change in the&hellip;This article was originally published on <a href="https://news.mongabay.com/2010/07/backbone-of-marine-food-chain-in-alarming-decline/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[A new image by NASA reveals the extent of the world&#8217;s marine dead zones, which a study in 2008 found were doubling every decade. At that time 415 dead zones had been identified worldwide. Dead zones are regions of the ocean where dissolved oxygen has fallen to such low levels that most marine species can no longer survive. Such conditions are often seasonal. The so-called dead zones are caused by agricultural runoff, especially nitrogen-rich fertilizers, as well as the burning of fossil fuels. Pollutants from these sources cause marine eutrophication, whereby the ecosystem receives too many nutrients, triggering massive algae blooms, which eventually die and are broken down bacteria. In breaking down the algae blooms, the bacteria consume excessive amounts of oxygen, essentially starving the marine system. Therefore the largest and most extreme dead zones occur near high populations and run-off areas for agriculture fertilizers. There are a few places in the world where low-oxygen waters are naturally occurring, such as the Bay of Bengal and southern Africa&#8217;s Atlantic west coast. Species in these regions have evolved greater resilience to low oxygen conditions, however even these areas are threatened by anthropogenic sources of nutrients. Created by satellite, the red circles on this map show the location and size of many of our planet’s dead zones. Black dots show where dead zones have been observed, but their size is unknown.

							<![CDATA[&#8216;Dead zones&#8217; in the ocean are called such for a reason. Every year agricultural run-off, especially fertilizer, floods the oceans with an abundance of nutrients leading to algae blooms, i.e. massive explosions of phytoplankton. The demise of these blooms, and the rise of bacteria feeding on them, eventually starves the entire area of oxygen creating a &#8216;dead zone&#8217; where the vast majority marine life can&#8217;t survive. Considered by most to be an environmental catastrophe, a new company is looking at dead zones in a different light: fuel and profit, as reported by the Wall Street Journal. LiveFuels Inc. sees the dead zones as a potential bonanza for algae-based biofuels. Such biofuels are currently being developed by a number of companies who plan to raise algae stocks in onshore facilities for fuel. But LiveFuels sees such an approach as cost-prohibitive. &#8220;It is too expensive for humans to grow algae, harvest it and get the water out and then convert it into a petroleum-like substitute,&#8221; said LiveFuels Chief Executive Lissa Morgenthaler-Jones. Instead LiveFuels has developed a plan to feed the algae in dead zones to fish, which will then be processed into oil. After gorging themselves, algae-eating fish will be captured, cooked, and then pressed to harvest their oils. This is the same process used to create Omega-3 oil in pill form, but LiveFuels also believes these oils can be turned into fuel. In other words: cars would run on ranched fish. LiveFuels is currently studying which fish, or grouping of species,&hellip;This article was originally published on <a href="https://news.mongabay.com/2009/08/biofuel-company-eyes-dead-zone-in-the-gulf-of-mexico-for-creating-fish-powered-fuel/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[A ‘monoculture of jellyfish’ threatens the oceans as we know them. It could be a plot of a (bad) science-fiction film: a man-made disaster creates spawns of millions upon millions of jellyfish which rapidly take over the ocean. Humans, starving for mahi-mahi and Chilean seabass, turn to jellyfish, which becomes the new tuna (after the tuna fishery has collapsed, of course). Fish sticks become jelly-sticks, and fish-and-chips becomes jelly-and-chips. The sci-fi film could end with the ominous image of a jellyfish evolving terrestrial limbs and pulling itself onto land—readying itself for a new conquest. While this scenario sounds ridiculous, all of it—except the last sentence, of course—could conceivably come to pass. Dr. Anthony Richardson calls this the ‘jellyfish joyride’ and it is already happening in parts of the ocean: diverse fish populations are being replaced by jellyfish.

Photo by Kenpei. &#8220;Dense jellyfish aggregations can be a natural feature of healthy ocean ecosystems, but a clear picture is now emerging of more severe and frequent jellyfish outbreaks worldwide,” Richardson, from the University of Queensland and CSIRO Climate Adaptation Flagship, explains. &#8220;In recent years, jellyfish blooms have been recorded in the Mediterranean, the Gulf of Mexico, the Black and Caspian Seas, the Northeast US coast, and particularly in Far East coastal waters.” Once jellyfish gain a foothold, Richardson says that if conditions are right they can establish a massive population at the expense of&hellip;This article was originally published on <a href="https://news.mongabay.com/2009/06/will-jellyfish-take-over-the-world/" data-wpel-link="internal">Mongabay</a>]]>

Jeremy Jackson, director of the Scripps Center for Marine Biodiversity and Conservation at the University of California, San Diego, synthesizes such reports and others into a new paper, published in the journal Proceedings of the National Academy of Sciences, that boldly lays out the scope of the oceanic emergency and what urgently needs to be done. &#8220;The purpose of&#8230; the paper is to make clear just how dire the situation is and how rapidly things are getting worse,&#8221; said Jackson. &#8220;It&#8217;s a lot like the issue of climate change that we had ignored for so long. If anything, the situation in the oceans could be worse because we are so close to the precipice in many ways&#8221;. For millennia the seas seemed an endless resource: unimaginably large and deep, brimming with life. How could such a seemingly inexhaustible recourse ever dwindle or even disappear? Increasingly, studies are showing catastrophic declines not only in fish favored for consumption, but in sea life altogether. A perfect storm of over-exploitation, nutrient pollution, and climate change is creating an uncertain future for the planet&#8217;s ocean, according to Jackson. Simply enforcing fisheries regulations would go a long way to preventing species extinctions.

							<![CDATA[Marine dead zones spread exponentially, doubling every decade since 1960 Marine &#8216;dead zones&#8217; double every decade Jeremy Hance, mongabay.com August 14, 2008 The number of marine dead zones have doubled every decade since the 1960s and show no sign of abating, warn scientists writing in the journal Science. Dead zones have expanded across the ocean at alarming rates. Currently 415 sites&#8212;usually along coastlines&#8212;have shown signs of seasonal to persistent hypoxia&#8212;a severe lack of oxygen. In a review, researchers Robert Diaz and Rutger Rosenberg argue that marine dead zones have &#8220;become a major worldwide environmental problem&#8221;, occupying a portion of the ocean equal to that of the United Kingdom. Growth continues to accelerate. Dead zones are caused by agricultural runoff, especially nitrogen-rich fertilizers, and the burning of fossil fuels. The pollutants cause marine eutrophication, whereby the ecosystem receives too many nutrients, triggering massive algae blooms, which eventually die and are broken down bacteria. By breaking down the algae the bacteria consume excessive amounts of oxygen, essentially starving the marine system. Estimated N deposition from global total N (NOy and NHx) emissions, totaling 105 Tg N per year. Image appeared in J.N. Galloway et al (2008). &#8220;Transformation of the Nitrogen Cycle: Recent Trends, Questions, and Potential Solutions,&#8221; Science 16 May 2008. The majority of dead zones are near large populations in wealthy nations. For example, the United States&#8217; east coast is covered with hypoxia sites, as is much of western and northern Europe.

							<![CDATA[U.S. dead zones may reach record levels this summer U.S. dead zones may reach record levels this summer mongabay.com July 15, 2008 &#8220;Dead zones&#8221; in the Gulf of Mexico and Chesapeake Bay will likely expand to record levels this summer due to rising rising agricultural runoff in part triggered by large-scale flooding in the Midwest, according to a forecast by a researcher from the University of Michigan. Donald Scavia, a professor at the University of Michigan&#8217;s School of Natural Resources and Environment, uses models driven by nutrient load estimates from the U.S. Geological Survey to makes the annual forecast. Scavia predicts that Chesapeake Bay&#8217;s summer dead zone will be 9.9 cubic kilometers (2.4 cubic miles), the sixth-highest on record, although if the area of low oxygen reaches the upper value of the forecast range of 12.3 cubic kilometers (3 cubic miles), it will be the highest on record. The Gulf of Mexico hypoxic zone (i.e., the area of bottom water with oxygen concentraions below 2 mg/l) is the second largest human-caused zone of hypoxia in the world&#8217;s coastal waters. Important fisheries are impacted at these low oxygen levels because fish, shrimp and crabs are forced to move from their preferred habitats and animals that cannot move away die. Below is a graph (www.gulfhypoxia.net) showing the changes in hypoxic volume since routine measurement began. Scavia projects the dead zone in the Gulf of Mexico will cover between 21,500 and 22,500 square kilometers (8,400-8,800 square miles) of bottom waters along the Louisiana-Texas&hellip;This article was originally published on <a href="https://news.mongabay.com/2008/07/u-s-dead-zones-may-reach-record-levels-this-summer/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Nitrogen pollution harming ecosystems and contributing to global warming Nitrogen pollution harming ecosystems and contributing to global warming mongabay.com May 15, 2008 Nitrogen pollution of the world&#8217;s oceans is harming marine ecosystems and contributing to global warming, report two reviews published in the journal Science. The research, which involved dozens of scientists from around the world, shows that human activity is dramatically altering nitrogen cycles in Earth&#8217;s oceans, soils, and atmosphere. The papers report that agricultural runoff and the burning of fossil fuels have boosted the supply of reactive nitrogen in the open oceans 50 percent above the normal range. The first paper, led by Robert Duce of Texas A&#038;M University, found that nitrogen produced by human activity is responsible for about a third of the nitrous oxide and a tenth of the carbon dioxide input to the world&#8217;s oceans each year. The researchers say the excess nitrogen &#8220;can deplete essential oxygen levels in the water and has significant effects on climate, food production, and ecosystems all over the world,&#8221; according to a statement from Science. Estimated N deposition from global total N (NOy and NHx) emissions, totaling 105 Tg N per year. Courtesy of Science. Duce and colleagues calculate that humans account for up to three percent of the new marine biological production annually. While the increased biological activity sequesters CO2 from the atmosphere, the process produces nitrous oxide (N20), a greenhouse gas far more potent than carbon dioxide. &#8220;This fertilization of the ocean by human activities has an&hellip;This article was originally published on <a href="https://news.mongabay.com/2008/05/nitrogen-pollution-harming-ecosystems-and-contributing-to-global-warming/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Global warming to worsen ocean dead zones, hurt fisheries Global warming to worsen ocean dead zones, hurt fisheries mongabay.com May 1, 2008 Warming oceans will worsen oxygen-deficient or hypoxic dead zones, affecting ecosystems and fisheries, warn researchers writing in the journal Science. Constructing a 50-year time series of oxygen concentration in tropical oceans, Lothar Stramma and colleagues show that hypoxic zones have expanded significantly in the past 50 years, especially in the eastern tropical Atlantic and the equatorial Pacific. &#8220;These trends affect carbon and nitrogen cycles, with fundamental implications for marine ecosystems and thereby fisheries resource management issues,&#8221; the authors write. &#8220;Given climate model projections, and the geological record that indicates times of widely distributed suboxic regions, sustained global ocean measurements of dissolved oxygen concentrations are needed&#8230; to more closely monitor variations in the strength and extent of the oxygen-minimum zone.&#8221; While climate-driven oxygen depletion results from the reduced capacity of warm water to store oxygen, hypoxia can also result from pollution. Last month a World Resources Institute study found 415 sites worldwide are suffering from over enrichment by nitrogen and phosphorus mostly as a result of agricultural runoff. Such over enrichment, or eutrophication, can trigger algal blooms that starve waters of oxygen, creating dead zones like that which forms in the Gulf of Mexico near the mouth of the Mississippi each year.

							<![CDATA[Ocean dead zones have nearly quadrupled since 1994 Ocean dead zones have nearly quadrupled since 1994 Coastal ecosystems threatened worldwide by nutrient-rich runoff Jeremy Hance, mongabay.com April 3, 2008 Coastal areas worldwide are suffering from over-enrichment of their waters by nitrogen and phosphorus, finds a new study from the World Resources Institute (WRI). This over-enrichment, known as eutrophication, causes numerous environmental problems, eventually devastating coastal environments. In overly nutrient-rich waters phytoplankton, micro- and macroalgae grow to excessive portions; these &#8216;algal blooms&#8217; diminish subaquatic vegetation, damage coral reefs, and deplete populations of fish, shellfish, marine mammals, and sea birds. In the worst case scenarios the massive algal blooms form hypoxic or dead zones due to loss of oxygen in the water, essentially condemning the ecosystem. Eutrophication is human-caused. The culprits are agricultural fertilizer, domesticated animal manure, industrial and urban runoff, sewage, and atmospheric nitrogen. These waste products have caused nitrogen and phosphorus to triple in coastal areas in the last fifty years alone. In Europe and the U.S. fertilizer and manure are the main sources, because much of their sewage is treated before entering the water system. In regions like Africa, Latin America, and Asia where sewage and industrial waste are rarely treated, these wastes provide larger sources of nitrogen and phosphorus. This map identifies 415 eutrophic and hypoxic coastal systems worldwide. Of these, 169 are documented hypoxic areas, 233 are areas of concern and 13 are systems in recovery. The map is based on research conducted by WRI’s NutrientNet program&hellip;This article was originally published on <a href="https://news.mongabay.com/2008/04/ocean-dead-zones-have-nearly-quadrupled-since-1994/" data-wpel-link="internal">Mongabay</a>]]>

The dead zone, an expanse of water so devoid of oxygen that sea life cannot live in it, partly results from the use of nitrogen-based fertilizers for corn crop. With corn acreage rapidly expanding in the U.S. as a result of subsidies for ethanol production, more fertilizers are ending up in the Gulf: each year an estimated 210 million pounds of excess nitrates are carried to the Gulf promoting massive algae blooms that fuel the hypoxia. These images show how ocean color changes from winter to summer in the Gulf of Mexico. Summertime satellite observations of ocean color from MODIS/Aqua show highly turbid waters which may include large blooms of phytoplankton extending from the mouth of the Mississippi River all the way to the Texas coast. When these blooms die and sink to the bottom, bacterial decomposition strips oxygen from the surrounding water, creating an environment very difficult for marine life to survive in. Reds and oranges represent high concentrations of phytoplankton and river sediment. Images and caption text courtesy of NASA&#8217;s Goddard Space Flight Center.

Why are oceans at risk from global warming? mongabay.com February 17, 2008 Climate change is putting the world&#8217;s oceans at risk by increasing the temperature and acidity of seawater, and altering atmospheric and oceanic circulation, warned a panel of scientists this week at the American Association for the Advancement of Science (AAAS) annual meeting in Boston. The vastness of our oceans may have engendered a sense of complacency about potential impacts from global climate change, said Jane Lubchenco, a marine biologist at Oregon State University and moderator of the panel. The worlds oceans are undergoing profound physical, chemical and biological changes whose impacts are just beginning to be felt. Ocean ecosystems are facing new stresses and new combinations of stress, said Gretchen Hofmann, a molecular physiologist at the University of California, Santa Barbara. The water is warmer, circulation patterns are changing in unpredictable ways, and oceans are becoming acidic. Particularly at risk are coral reefs. Rising temperatures increase the risk of coral bleaching, while elevated carbon dioxide concentrations increase ocean acidity, making it more difficult for corals to form their calcium carbonate structural basis. Coral bleaching occurs when symbiotic algae that provide corals with sustenance are expelled, leaving corals more susceptible to disease and death. Research published over the past year indicates that PETM climate change helped drive the evolution of modern primates by causing the dispersal of tarsier-like primates across the globe.

							<![CDATA[U.S. biofuels policy drives deforestation in Indonesia, the Amazon U.S. biofuels policy drives deforestation in Indonesia, the Amazon Rhett A. Butler, mongabay.com January 17, 2008 U.S. incentives for biofuel production are promoting deforestation in southeast Asia and the Amazon by driving up crop prices and displacing energy feedstock production, say researchers. William Laurance, a senior scientist at the Smithsonian Tropical Research Institute in Panama, says that massive subsidies to promote American corn production for ethanol have shifted soy production to Brazil where large areas of cerrado grasslands are being torn up for soybean farms. The expansion of soy in the region is contributing to deforestation in the Amazon. &#8220;Some forests are directly cleared for soy farms. Farmers also purchase large expanses of cattle pasture for soy production, effectively pushing the ranchers further into the Amazonian frontier or onto lands unsuitable for soy production,&#8221; said Laurance. Projected soybean exports for Brazil and the United States, 2004-2015. Chart based on USDA data. Click to enlarge. &#8220;In addition, higher soy costs tend to raise beef prices because soy-based livestock feeds become more expensive, creating an indirect incentive for forest conversion to pasture,&#8221; added Laurance. &#8220;Finally, the powerful Brazilian soy lobby has been a driving force behind initiatives to expand Amazonian highway networks, which greatly increase access to forests for ranchers, farmers, loggers, and land speculators.&#8221; Satellite imagery from NASA supports Laurance. Data released last summer indicates that much of the recent burning is concentrated around two major Amazon roads: Trans-Amazon highway in the&hellip;This article was originally published on <a href="https://news.mongabay.com/2008/01/u-s-biofuels-policy-drives-deforestation-in-indonesia-the-amazon/" data-wpel-link="internal">Mongabay</a>]]>

The dead done, characterized by low oxygen levels, formed in mid-June this year and killed thousands of crabs, sea stars and marine worms. It was the strongest event ever recorded in the area. &#8220;The figures were just off the charts this year,&#8221; said Dr. Francis Chan, a marine ecologist with Oregon State University. &#8220;We&#8217;re very interested now in seeing how the ocean recovers. There is much we don&#8217;t know about how sensitive or resilient these ocean systems are, but an event of this magnitude gives us the chance to gain some real insights into how marine systems function and can recover. We expect some fish to return fairly quickly, but with other life forms, it&#8217;s hard to say. And we have deadlines, we need to get a lot of this information before another possible hypoxic event starts next year.&#8221; Scientists currently have poor understanding of what causes the conditions and say the dead zone could well return next year. &#8220;Given what&#8217;s happened, it would not be surprising if hypoxic conditions developed next year as well, but we can&#8217;t say that for sure,&#8221; said Dr. Jack Barth, a professor of oceanic and atmospheric sciences at Oregon State University. &#8220;And we don&#8217;t know&hellip;This article was originally published on <a href="https://news.mongabay.com/2006/10/oregon-dead-zone-event-over-but-cause-still-unknown/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[&#8216;Dead Zone&#8217; causing wave of death off Oregon coast &#8216;Dead Zone&#8217; causing wave of death off Oregon coast Oregon State University August 10, 2006 The most severe low-oxygen ocean conditions ever observed on the West Coast of the United States have turned parts of the seafloor off Oregon into a carpet of dead Dungeness crabs and rotting sea worms, a new survey shows. Virtually all of the fish appear to have fled the area. Scientists, who this week had been looking for signs of the end of this &#8220;dead zone,&#8221; have instead found even more extreme drops in oxygen along the seafloor. This is by far the worst such event since the phenomenon was first identified in 2002, according to researchers at Oregon State University. Levels of dissolved oxygen are approaching zero in some locations. &#8220;We saw a crab graveyard and no fish the entire day,&#8221; said Jane Lubchenco, the Valley Professor of Marine Biology at OSU. &#8220;Thousands and thousands of dead crab and molts were littering the ocean floor, many sea stars were dead, and the fish have either left the area or have died and been washed away. &#8220;Seeing so much carnage on the video screens was shocking and depressing,&#8221; she said.

							<![CDATA[Hypoxic &#8220;dead zone&#8221; growing off the Oregon Coast Hypoxic &#8220;dead zone&#8221; growing off the Oregon Coast By David Stauth Oregon State University July 31, 2006 A hypoxic &#8220;dead zone&#8221; has formed off the Oregon Coast for the fifth time in five years, according to researchers at Oregon State University. Oxygen measurements of ocean water off the Oregon coast are helping Oregon State University researchers understand the &#8220;dead zones&#8221; that have concerned scientists in recent years. In this 2004 photo, Chris Holmes and Francis Chan, members of the Partnership for Interdisciplinary Study of Coastal Oceans, bring up a sample.

The low oxygen waters extended from near the Mississippi River to the Louisiana/Texas border. The long-term average since mapping began in 1985 is 12,700 km2 (or 4,800 square miles) Gulf dead zone may by increasing according to researchers A group of scientists reported that the &#8220;dead zone&#8221; area of the Gulf of Mexico &#8212; an expanse of water so devoid of oxygen that sea life cannot live in it &#8212; has appeared much earlier than usual this year meaning it could be potentially larger and affect marine life more adversely than normal.
