Iceberg lettuce, she reports, is 96 percent water by weight. And the other 4 percent doesn't offer much in the way of nutrition&mdash;a <a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2476/2">whole salad's worth</a> has just a gram of fiber (a fourth of what you'd get from a <a href="http://nutritiondata.self.com/facts/fruits-and-fruit-juices/1809/2">medium apple</a>) and barely a tenth of a day's requirement of vitamin A and C.</p> <p>Similar-sized servings of other salad greens, including&nbsp;<a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/7361/2" target="_blank">red leaf lettuce,</a> <a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2475/2" target="_blank">romaine, </a><a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/3025/2">arugula,</a> and <a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2626/2">spinach, </a>deliver a much bigger nutritional punch. But the great bulk of these popular salad greens are grown in California and shipped across the country. By the time they're cut, washed, packaged, trucked, and stacked on that pious supermarket shelf in your hometown, they have surrendered the bulk of their nutritional content, <a href="http://www.dailymail.co.uk/news/article-3005061/Are-ready-prepared-fruit-veg-healthy-think-Tests-far-lower-levels-vitamin-C-unprepared-produce.html">strong evidence</a> suggests.</p> <p>And let's face it: Fancy marketing prose aside, what those bags too often offer is wan and bland, not the peppery jolt of, say, fresh-picked arugula. So what you're mainly buying are limp tissues of water, most likely shipped from one of two California growing regions (the <a href="http://www.motherjones.com/tom-philpott/2015/05/your-winter-vegetables-are-grown-desert-watered-dwindling-river">Imperial</a> or the <a href="http://www.motherjones.com/tom-philpott/2015/07/drought-salinas-valley-salad-greens">Salinas</a> valley) with severe long-term water issues.</p> <p>Haspel adds that in addition to their dubious nutrient density and water economics, salad greens rank as our "top source of food waste" (she reports that 1 billion pounds of salad greens spoil before they're consumed each year) and also the "chief culprit for foodborne illnesses" (the Centers for Disease Control and Prevention says leafy greens are "responsible for <a href="http://wwwnc.cdc.gov/eid/article/19/3/11-1866_article">22 percent of all food-borne illnesses from 1998-2008</a>").</p> <p>What, then, to make of the social expectation that no healthy meal is complete without a salad? Haspel suggests pulling back from it: "Maybe we should stop thinking about salad as a wholesome staple, and start thinking about it as a resource-hungry luxury."</p> <p>I try to confine my fresh leafy-green consumption to those times of year when my own garden or farmers around me can readily churn out arugula, spinach, and other nutrient-dense greens. When good salad greens are scarce&mdash;as they are now in the infernal Texas summer&mdash;I often make a straight <a href="http://www.epicurious.com/recipes/food/views/parsley-salad-14662">parsley salad</a>; <a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2513/2">parsley</a> has nearly four times the vitamin A and eight times the vitamin C of <a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/3025/2">arugula</a>, which itself is no slouch compared with <a href="http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2476/2" target="_blank">iceberg lettuce</a>. Or I mash up this bright-tasting herb with a raw seasonal vegetable, like cucumbers, along with heat-hardy basil and garlic chives. I've got my eye on this <em>Bon Appetit</em> <a href="http://www.bonappetit.com/recipe/scallion-salad?mbid=social_twitter">recipe</a> for a salad built entirely on scallions and cilantro.&nbsp;</p> <p>Way back in 1988, the restaurant critic Jeffrey Steingarten penned a marvelous essay called "Salad: The Silent Killer" (you can read it <a href="https://books.google.com/books?id=YkkhgGoE3_cC&amp;pg=PA177&amp;lpg=PA177&amp;dq=%22salad:+the+silent+killer%22+steingarten&amp;source=bl&amp;ots=UTbDavr93M&amp;sig=5a97xcQSUNUkLA2dRp4RKHGvGic&amp;hl=en&amp;sa=X&amp;ved=0CCYQ6AEwAWoVChMIgYqz0OvCxwIVxBiSCh1HWQD9#v=onepage&amp;q=%22salad%3A%20the%20silent%20killer%22%20steingarten&amp;f=false">here</a>). In it, he deplored the habit of "tuck[ing] into the dreariest salad simply because it is raw and green. No matter that the arugula is edged with brown&hellip;[or] that it is the dead of winter and the salad chills us to the marrow." His real target was out-of-season, cross country-trucked, flavorless greens. The convention that no healthy dinner is complete without them has persisted, and it remains absurd.

"There is shit in the meat.&rdquo;&nbsp;</p> <p>A new <em>Consumer Reports</em> <a href="http://www.consumerreports.org/cro/beefsafety">investigation</a> suggests things haven't changed much since the publication of Schlosser's 2001 blockbuster. The team tested 300 packages of ground beef, bought from more than 100 grocery, big-box, and natural food stores in 26 cities nationwide. The result:</p> <blockquote> <p>All 458 pounds of beef we examined contained bacteria that signified fecal contamination (enterococcus and/or non-toxin-producing E. coli), which can cause blood or urinary tract infections.</p> </blockquote> <p>But not all burger meat is created equal. The researchers also compared the bacterial load of beef from conventionally raised cows (181 samples) to that of their no-antibiotic, grass fed, and organic peers (116 samples total), grouped under the heading "more sustainably produced." Here's what they found:</p> <div class="inline inline-center" style="display: table; width: 1%"><img alt="" class="image" src="/files/chart%201.jpg"><div class="caption">From "How Safe is Your Beef?," <em>Consumer Reports</em></div> </div> <p>The bacterial implications of beef production practices really emerged when the researchers tested the bacterial strains for resistance to antibiotics. Nearly a fifth of conventional ground beef carried bacteria resistant to three or more classes of antibiotics&mdash;more than double the number found in the "more sustainably produced" samples, and triple that found in samples from cows raised outdoors on grass.</p> <div class="inline inline-center" style="display: table; width: 1%"><img alt="" class="image" src="/files/chart2_4.jpg"><div class="caption">From "How Safe is Your Beef?," <em>Consumer Reports</em></div> </div> <p>The article offers plenty of information that could explain these differences. As for why essentially all ground beef carries fecal bacteria, the slaughter and processing of huge animals is messy&mdash;feces caked on the hide or trapped in intestines can easily move onto the carcass. That's not such a big deal in steaks and roasts, because the bacteria tend to stay on the surface, so "when you cook them, the outside is likely to get hot enough to kill any bugs." But with ground beef, "the bacteria get mixed throughout, contaminating all of the meat&mdash;including what&rsquo;s in the middle of your hamburger."</p> <p>Then there's this problem: "The meat and fat trimmings often come from multiple animals, so meat from a single contaminated cow can end up in many packages of ground beef."</p> <p>As for why conventional production&mdash;the source of 97 percent of US burger meat, according to <em>CR</em>&mdash;is moderately more likely to contain certain bacteria like E. coli, and much more likely to contain multidrug-resistant strains, the report delivers a detailed look at the different production systems.</p> <p>Conventionally raised cows start out on grass but spend the final months of their lives on feedlots, where they fatten on diets of corn and soybeans, even though "cows' digestive systems aren't designed to easily process high-starch foods such as corn and soy," creating an acidic environment in the cows' digestive tract that can "lead to ulcers and infections" and "shed more E. coli in their manure.</p> <p>And corn and soy aren't the only delicacies feedlot cows feast on.</p> <blockquote> <p>[Their feed can also include] include candy (such as gummy bears, lemon drops, and chocolate) to boost their sugar intake and plastic pellets to substitute for the fiber they would otherwise get from grass. Cattle feed can also contain parts of slaughtered hogs and chickens that are not used in food production, and dried manure and litter from chicken barns.</p> </blockquote> <p>In addition, they can also receive regular low doses of antibiotics, both to prevent infections and promote faster growth, although the Food and Drug Administration has launched a voluntary program to limit the latter use. One common feedlot antibiotic, tylosin&mdash;used to ward off liver abscesses&mdash;is in "a class of antibiotics that the World Health Organization categorizes as 'critically important' for human medicine," <em>CR</em> reports.</p> <p>The magazine recommends that consumers buy from the alternative supply chains "whenever possible," adding that "sustainable methods run the gamut from the very basic 'raised without antibiotics' to the most sustainable, which is grass-fed organic." (The article contains ample detail on each.) And when you get it home, handle it carefully and cook it to 160 degrees. After all, there's shit in pretty much all the ground beef.</p></body></html> Tom Philpott Food and Ag Mon, 24 Aug 2015 10:00:13 +0000 Tom Philpott 282531 at http://www.motherjones.com The Drought Is Making California Sink—And Climate Change Makes the Drought Worse http://www.motherjones.com/tom-philpott/2015/08/drought-making-california-sink-climate-change-makes-drought-worse-subsidence <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body><p>The policymakers tasked with overseeing California's ever-stressed water supply got two pieces of rough news this week.</p> <p><strong>&bull; The Central Valley is sinking&mdash;really fast. </strong>A new <a href="http://www.jpl.nasa.gov/news/news.php?release=2015-273" target="_blank">satellite analysis from NASA</a> found that vast swaths of the state's most important growing region&mdash;a massive national supplier of vegetables, fruit, and nuts nationwide&mdash;is dropping as farmers tap underground aquifers to compensate for lack of water from the state's irrigation projects. Subsidence, as the phenomenon is known, damages crucial infrastructure like aqueducts, train tracks, bridges, roads, and flood-control structures. As a June 2015 <a href="http://www.motherjones.com/environment/2015/06/california-sinking-drought-ground-water" target="_blank">Center for Investigate Reporting article</a> showed, no state agency keeps track of the financial cost exacted by repairing the ravages of subsidence, but the price tag is likely already in the tens of millions of dollars. Some of the most severe subsidence, NASA found, occurred along the California Aqueduct, damaging a network of canals, pipelines, and tunnels that carries water collected from the Sierra Nevada Mountains to the southern Central Valley's farms. Subsidence also permanently reduces the underground aquifers' water storage capacity, NASA adds.</p> <p><strong>&bull; Climate change is making the whole situation worse. </strong>In addition to an epochal drought&mdash;driven mainly by lack of winter snows in the Sierra Nevada mountains, the engine of California's water system&mdash;the state is also experiencing <a href="http://www.bloomberg.com/news/articles/2015-04-10/california-s-new-era-of-heat-destroys-all-previous-records#media-3">historically warm temperatures</a>. And while climate change&nbsp; isn't likely the main factor behind the precipitation drop, it does likely drive the current heat wave. This year, California and much of the western US have endured record-high temperatures, the National Oceanic and Atmospheric Administration <a href="http://www.ncdc.noaa.gov/sotc/service/national/regionaltavgrank/201501-201507.gif" target="_blank">reports</a>.</p> <div class="inline inline-center" style="display: table; width: 1%"><img alt="" class="image" src="/files/201501-201507%20copy.jpg"><div class="caption">NOAA</div> </div> <p>Hot weather, of course, <a href="http://geochange.er.usgs.gov/sw/changes/natural/et/">compounds the impact of droughts</a>: It accelerates the loss of water stored in soil, vegetation, aqueducts, and reservoirs, a process known as evapotranspiration. In a just-published <a href="http://onlinelibrary.wiley.com/doi/10.1002/2015GL064924/full" target="_blank">paper</a>, researchers from Columbia University and the University of Idaho looked at temperature and precipitation data gathered between 1901 and 2014 and compared them to climate change models. They concluded that California's recent dearth of precipitation can be explained mainly by natural variability, but that that climate change-induced evapotranspiration has contributed dramatically to the drought's severity. Think of it like this: Lack of precipitation has severely limited new water coming into California, and climate change has hindered the landscape's ability to hold onto what little water is available. Over all, increased evapotranspiration is responsible for as much as 27 percent of the state's current water shortage, they calculated. Worse, going forward, "anthropogenic warming has substantially increased the overall likelihood of extreme California droughts," they concluded.</p></body></html> Tom Philpott Food and Ag Thu, 20 Aug 2015 22:04:47 +0000 Tom Philpott 282431 at http://www.motherjones.com New Monsanto Spray Kills Bugs by Messing With Their Genes http://www.motherjones.com/tom-philpott/2015/08/coming-farm-field-near-you-gene-silencing-pesticides-RNA-RNAi <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body><p>In a <a href="http://www.technologyreview.com/featuredstory/540136/the-next-great-gmo-debate/">fascinating long piece</a> in <em>MIT Technology Review,</em> <a href="http://www.technologyreview.com/contributor/antonio-regalado/">Antonio Regalado</a> examines the genetically modified seed industry's latest blockbuster app in development&mdash;one that has nothing to do with seeds. Instead, it involves the industry's other bread-and-butter product: pesticide sprays. But we're not talking about the poisonous chemicals you convinced your dad to stop dousing the lawn with. The novel sprays in question are powered by a genetic technology called RNA interference, which promises to kill specific insects and weeds by silencing genes crucial to their survival, while leaving nontarget species unscathed.</p> <p>RNAi, as it's known, is an emerging science; the two US researchers who discovered it <a href="http://www.nobelprize.org/nobel_prizes/medicine/laureates/2006/" target="_blank">brought home a Nobel Prize</a> in 2006. Regalado describes the process like this:</p> <blockquote> <p>The cells of plants and animals carry their instructions in the form of DNA. To make a protein, the sequence of genetic letters in each gene gets copied into matching strands of RNA, which then float out of the nucleus to guide the protein-making machinery of the cell. RNA interference, or gene silencing, is a way to destroy specific RNA messages so that a particular protein is not made.</p> </blockquote> <p>If you can nix RNA messages that exist to generate crucial genes, you've got yourself an effective bug or weed killer. And GMO seed and pesticide behemoth Monsanto thinks it has just that. Robb Fraley, the company's chief technology officer and a pioneer in creating GM seeds, told Regalado that within a few years, RNA sprays would "open up a whole new way to use biotechnology" that "doesn't have the same stigma, the same intensive regulatory studies and cost that we would normally associate with GMOs." Fraley described the novel technology as "incredible" and "breathtaking."</p> <p>It's not hard to see why the veteran agrichemical and biotech exec is so amped for something new to load into a crop duster. Monsanto's GM herbicide-resistant and insecticidal traits still dominate the highly lucrative US corn, soybean, and cotton seed markets, but these cash-cow products are victims of their own success, so widely used that <a href="http://www.iowafarmertoday.com/news/crop/agronomist-even-good-farmers-get-resistant-weeds/article_0e1566f2-4075-11e5-86e3-6b337b379b32.html">weeds</a> and <a href="http://www.agriculture.com/crops/corn/entomologist-bt-effectiveness-to-cn_136-ar49674">pests</a> are rapidly developing resistance to them. The company's flagship herbicide, Roundup, still generates about <a href="http://www.monsanto.com/investors/documents/annual%20report/2014/2014_monsanto_annualreport.pdf">$5 billion in sales annually</a>, but it went off-patent years ago, and it was recently declared a <a href="http://www.motherjones.com/tom-philpott/2015/03/monsanto-herbicide-cause-cancer">"probable carcinogen"</a> by the World Health Organization&mdash;a finding Monsanto <a href="http://www.reuters.com/article/2015/03/24/us-monsanto-herbicide-idUSKBN0MK2GF20150324">disputes</a>.</p> <p>Such concerns are widely seen as the reason Monsanto is <a href="http://www.motherjones.com/tom-philpott/2015/05/monsanto-syngenta-merger-45-billion-pesticides">so hotly pursuing a takeover</a> of its rival, Syngenta, which focuses much more on pesticides than novel seeds. Syngenta, too, is developing RNAi technology, reports Regalado&mdash;back in 2012, it spent $523 million to <a href="http://www.bloomberg.com/news/articles/2012-09-21/syngenta-agrees-to-buy-biotech-rival-devgen-for-523-million-1-">buy Devgen</a>, a company that had been developing the novel sprays.</p> <p>However, there's no reason to assume crop dusters will be strafing farm fields with gene-silencing sprays anytime soon. As Regalado notes, they're very little studied outside of corporate labs. "So far, only a few scientific publications even mention the idea of RNA sprays," he writes. "That makes it hard to judge companies' claims."</p> <p>The first obstacle is technological&mdash;the problem of "how to get a large, electrically charged molecule like RNA to move through a plant's waxy cuticle and into its cells," Regalado writes. That's crucial, because the technology works like this: A targeted bug&mdash;the one drawing attention now from Monsanto is the Colorado potato beetle&mdash;chomps on a leaf that's been sprayed by RNA solution and then, fatally, gets critical genes turned off. To make that happen, you have to get the RNA material into the leaf.</p> <p>The most promising solution so far is to "encapsulate the RNA in synthetic nanoparticles called lipidoids&mdash;greasy blobs with specialized chemical tails," Regalado reports. "The idea is to slip them into a plant, where the coating will dissolve, releasing the RNA."</p> <p>This nanotech booster to Monsanto's new bug killer won't likely raise red flags from government overseers. As I've shown before, both <a href="http://www.motherjones.com/tom-philpott/2014/05/regulation-nanoparticles-workplace-exposure-hazards">nanotechnology</a> and <a href="http://www.motherjones.com/tom-philpott/2015/07/are-farmers-using-nanotech-fight-superweeds">adjuvants</a>&mdash;the compounds mixed with pesticides to help them break into plants&mdash;are lightly regulated.</p> <p>However, the RNAi compound itself will have to be reviewed by the Environmental Protection Agency, which vets new pesticides before they reach farm fields. Early indications suggest the going will be bumpy. Last year, the EPA convened a <a href="http://www.epa.gov/scipoly/sap/meetings/2014/january/012814minutes.pdf">scientific advisory panel</a> to assess the human health and ecological risks posed by emerging RNAi crop technologies.</p> <p>The panel concluded there's "no convincing evidence" that RNAi material poses a threat to humans or other animals&mdash;the digestive process likely destroys it before it can do harm. But for nontarget insects in the field, they concluded, it's a different story. The technology's boosters claim the technology can target particular pests and leave everything else in the ecosystem alone. The independent scientists on the EPA panel were not convinced. They noted "uncertainties in the potential modes of action in non-target species, potential for chronic and sublethal effects, and potential unintended consequences in the various life stages of non-target organisms." As a result, they found &nbsp;"sufficient justification to question" whether the EPA's current methods of evaluating new pesticides, which were designed to vet chemicals, apply to these gene-altering treatments.</p> <p>And the technology is so novel that figuring out what those tests should be will be hard&mdash; it "cannot be done without a better understanding" of exactly how the technology works, the panel concluded. US Department of Agriculture entomologists Jonathan Lundgren and Jian Duan raised similar concerns in a <a href="http://www.bioone.org/doi/abs/10.1525/bio.2013.63.8.8">2013 paper</a>.</p> <p>One particular concern for the EPA panel was the amount of time RNAi material stays intact after it's sprayed. Monsanto says not to worry, because "when the company doused dirt with RNA, it degraded and was undetectable after 48 hours," Regalado reports. But he adds that Monsanto "wants to develop longer-lasting formulations," noting that another RNAi spray it's developing for trees was shown to persist for months. "What's more," Regalado&nbsp;notes, "Monsanto's own discoveries have underscored the surprising ways in which double-stranded RNA can move between species"&mdash;not exactly a comforting aspect of a technology Monsanto hopes to see widely used on farm fields.</p> <p>A Monsanto geneticist told Regalado that the company hopes to get its first RNAi spray, one targeting potato beetles, into the market by 2020. The company is also working on an RNAi product to add to its failing Roundup herbicide&mdash;one it hopes can turn off the resistant genes in the superweeds now rampant on US farm fields. But that's well behind the potato beetle product in Monsanto's development timeline, a company spokeswoman told me.</p> <p>In addition to its sprays, Monsanto has an RNAi-enhanced corn crop in the pipeline: a corn type engineered to contain RNA that was designed to kill a common pest called the rootworm. It's "currently pending approval from the EPA," the Monsanto spokeswoman said. "We are planning for a full commercial launch by the end of the decade, pending key regulatory approvals."</p> <p>Doug Gurian-Sherman, a plant pathologist by training who covers biotechnology for the Center for Food Safety, echoed the EPA panel's concerns."These are very complex biological systems,&nbsp;and their interactions evolve, and are not static," he said. "So it is really impossible to predict all the things that could go wrong. That does not mean we should be paranoid about them, but we should be at least reasonably cautious and skeptical about claims of both safety and efficacy, since there is little experience or research to rely on."</p> <p>He also questioned Monsanto's claim, reported by Regalado, that insects won't likely develop resistance to the RNAi treatments, as they have to most chemical treatments in the past. "This is&nbsp;surprisingly reminiscent of <a href="http://www.motherjones.com/tom-philpott/2012/03/monsanto-scientists-superweeds-NPR">Monsanto's</a> <a href="http://www.aphis.usda.gov/brs/aphisdocs/93_25801p.pdf">assurances</a> in the '90s that weeds would be very unlikely to develop resistance to the glyphosate [Roundup] herbicide&hellip;and now we have an epidemic of glyphosate resistant weeds," Gurian-Sherman said.&nbsp;</p></body></html> Tom Philpott Food and Ag Science Top Stories Wed, 19 Aug 2015 10:05:11 +0000 Tom Philpott 282186 at http://www.motherjones.com How the Midwest's Corn Farms Are Cooking the Planet http://www.motherjones.com/tom-philpott/2015/08/how-midwests-corn-farms-are-cooking-planet <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body><p>I've been thinking a lot recently about how fertilizer from the Midwest's big corn farms seeps into streams and causes trouble&mdash;fouling water supplies in <a href="http://www.motherjones.com/tom-philpott/2015/06/attention-viagra-users-columbus-dont-drink-water">Columbus</a>, <a href="http://www.motherjones.com/tom-philpott/2015/08/giant-toxic-algae-bloom-haunts-toledo">Toledo</a>, <a href="http://www.desmoinesregister.com/story/money/agriculture/2015/05/28/water-works-nitrate-removal-hits-record-days/28095517/">Des Moines</a>, <a href="http://www.desmoinesregister.com/story/money/agriculture/2015/07/04/high-nitrates-iowa-cities/29720695/" target="_blank">and 60 other towns in Iowa</a>, and generating a <a href="http://www.noaanews.noaa.gov/stories2015/080415-gulf-of-mexico-dead-zone-above-average.html">Connecticut-sized dead zone</a> at the heart of the continental United States' most productive fishery, the Gulf of Mexico. (Farms in the region also plant soybeans, but <a href="http://www.ers.usda.gov/amber-waves/2011-september/nitrogen-footprint.aspx#.VcpuSRNVikp" target="_blank">corn is by far the bigger fertilizer user</a>.) But there's another way the Corn Belt's fertilizer habit damages a common resource: by releasing nitrous oxide (N<sub>2</sub>O), a <a href="http://www.epa.gov/climatechange/ghgemissions/gases/n2o.html">greenhouse gas with nearly 300 times the heat-trapping power of carbon dioxide</a>.</p> <p>It turns out that the region's farms are likely generating much more nitrous oxide than scientists previously thought, according to a new <a href="http://www.pnas.org/content/early/2015/07/21/1503598112">peer-reviewed study</a> by a team of researchers from the University of Minnesota, Yale, and the US Department of Agriculture.</p> <p>Scientists had assumed that most nitrous oxide emissions from farming occurred at the soil level&mdash;some of the nitrogen fertilizer applied onto farmland vaporizes into nitrous oxide. But as citizens of Des Moines, Columbus, and the Gulf coast know well, nitrogen fertilizer doesn't stay in soil; a portion of it&nbsp;leaches into streams. And some of that escaped nitrogen, too, transforms into nitrous oxide.</p> <p>To measure how much, the team, led by University of Minnesota researcher Pete Turner measured N<sub>2</sub>O emissions at 19 streams over a two-year period in ag-intensive southeastern Minnesota. They found that standard greenhouse gas emission measures, such as those used by the Intergovernmental Panel on Climate Change (IPCC), have been undercounting these "riverine" emission&nbsp;sources by a factor of nine; and overall N<sub>2</sub>O emissions from the area are underestimated by about 40 percent.</p> <p>While they only took measurements in one small part of the US Midwest, the researchers write that other regions of the globe have similar conditions: large swaths of land dominated by fertilizer-intensive farming. Such areas include the rest of the US Corn Belt plus parts of China, Europe, and India. These industrial-scale farming regions, which together make up a landmass of about 580 million acres (nearly six times the size of California), are the globe's most potent sources of nitrous oxide, and we're likely drastically undercounting their total emissions, the study suggests.</p> <p>Altogether, the paper estimates, typical assessments undercount nitrous oxide emission in the Corn Belt by about 25 gigagrams annually. According to my back-of-the-envelope calculation, that's the equivalent of about 1.6 million cars on the road over a year (<a href="http://www.epa.gov/climatechange/ghgemissions/gases/n2o.html" target="_blank">assuming</a> that 1 gram of nitrous oxide has the heat-trapping power of about 300 grams of carbon dioxide, and that the average passenger car burns through <a href="http://www.epa.gov/cleanenergy/energy-resources/refs.html" target="_blank">4.75 metric tons of CO2 equivalent each yea</a>r).</p> <p>So efforts to rein in fertilizer runoff in the Corn Belt aren't just about cleaner water and lower filtration bills for the area's urban residents, or a more vibrant Gulf of Mexico fishery. They're also about stabilizing the climate.

The bad news is that death rates from neurological diseases like Alzheimer's have soared&mdash;and Americans are much likelier to die from these diseases than their peers in most other developed countries.</p> <p>To get their results, researchers from Bournemouth University in the United Kingdom looked at World Health Organization mortality statistics for 21 developed nations, comparing the 1989&ndash;91 period with the 2008&ndash;10 time frame.</p> <p><iframe allowfullscreen="allowfullscreen" allowtransparency="true" frameborder="0" height="550" mozallowfullscreen="mozallowfullscreen" msallowfullscreen="msallowfullscreen" oallowfullscreen="oallowfullscreen" src="//mjdwcharts.s3.amazonaws.com/1R2ma/2/index.html" webkitallowfullscreen="webkitallowfullscreen" width="100%"></iframe></p> <p>For adults between the ages of 55 and 74, overall neurological death rates barely budged, rising 2 percent for men and 1 percent for women. But here in the United States, things got dramatically worse&mdash;death rates from dementia and other brain-related illnesses like&nbsp;Parkinson's disease and motor neuron disease spiked, jumping 82 percent for men and 48 percent for women. American men and women in this age group now have the second-highest neurological death rates in the developed world, behind Finland. In the earlier period, they ranked 17th and 11th, respectively.</p> <p>For the elderly (aged 75 and up), the situation is even more dire. Overall, the neuro-related death rate jumped 114 percent for men and 185 percent for women. Here in the United States, elderly death rates from neurological causes leapt more than twofold (368 percent) for men and more than fivefold (663 percent) for women. Neurological causes now kill more elderly American women than cancer does.</p> <p>Over the same time frame, death rates from cancer and cardiovascular disease dropped, both in the developed world overall and in the United States in particular. For 55- to 74-year-olds, male cancer death rates fell 20 percent overall, and US rates dropped 36 percent. Women in that age group showed a 16 percent reduction in cancer deaths throughout the developed world and an 18 percent reduction in the United States. Similar trends held true for heart-related diseases.</p> <p>When you look only at Alzheimer's isolated from other neurological diseases, you'll also see a relative spike in deaths, as this <a href="http://www.alz.org/facts/downloads/facts_figures_2015.pdf">chart</a> from a 2015 report by the US-based Alzheimer's Association shows.</p> <div class="inline inline-center" style="display: table; width: 1%"><img alt="" class="image" src="/files/chart_8.jpg"><div class="caption">Alzheimer's Association</div> </div> <p>What gives? Why are so many Americans so much more at risking of dying of neurological diseases like Alzheimer's, even as other threats recede? And in the developed world as a whole, why are neurological-related death rates rising for people over the age of 75?</p> <p>One obvious factor is that medical science has come up with all sorts of treatments to prolong the lives of people with cancer and cardiovascular conditions, while treatments for Alzheimer's have proven elusive. It could be simply that Alzheimer's and other neurological diseases are "diseases of the elderly"&mdash;that our brains are doomed to decline past a certain age, and more and more people are surviving cancer and heart disease only to "develop diseases that they would not have lived long enough to have acquired in previous times," as the authors of the UK study put it. But that probably doesn&rsquo;t fully explain the findings, particularly since some countries, like the United States, have fared so much worse than others.</p> <p>The study's authors don't speculate much on what's driving the trends they identified; they suggest that lifestyle factors might play a role. Heather Snyder, director of medical and scientific relations at the Alzheimer's Association, told me that there are significant but still-inconclusive links between cognitive decline and diet-related maladies like obesity and diabetes. A 2015 <a href="https://www.motherjones.com/files/baumgart_et_al_2015.pdf" target="_blank">paper</a> she co-authored delivers a broad state-of-the-science view on the relationship.
