California has more cattle feedlots than any state, new map shows
California also has the most feedlot acreage: over 85,000 acres, or 130 square miles, the majority of it for dairy cows. Tulare County has more than any county in the country — 304 operations. Were it a state, it would would rank No. 8, researchers at the University of Michigan and UC Santa Barbara found.
Until now, there has been no national database of animal feeding operations. The federal government doesn't keep one, and states tend to keep what information they have confidential.
The researchers say their data will allow local governments and non-governmental organizations to set targeted environmental, health and economic policies for their regions.
'It's really awesome research,' said Andrew deCoriolis, the director of FarmFoward, an anti-industrial agriculture group. 'This is by far the most comprehensive research I've seen, both in the map ... and the quantification of the number of operations.'
They also mapped the geography of hog raising. The U.S. is the world's second-largest livestock producer (behind China) — and most of the animals are raised in confined feeding operations: 70% of cattle and 98% of hogs.
The facilities pack many animals into relatively small areas where they are fed energy-dense diets and raised for milk or meat before they are eventually slaughtered.
In California the average dairy operation is 1,300 animals, but they range from a few hundred cows in the north coast, to more than 10,000 in the San Joaquin Valley.
For decades, such operations have been associated with degraded air and water quality. There is often little vegetation and animals kick up dirt and dried manure with their hooves when they move. Other research has found the industry workforce is often underinsured and economically disadvantaged. More than 50% of the nation's dairy workers may be undocumented.
The lack of precise location data has meant that local governments, academics and nonprofit organizations have struggled to document the effects of these facilities on the environment and community health.
So the researchers decided to build a database and map combining existing data sets — national, regional, business and crowd-sourced — that they cross-referenced with Google Earth. Then they scoured satellite imagery for more than two years, eventually pinpointing 15,726 cattle and hog feeding lots and their extent. The collective footprint exceeded 658,500 acres, or 1,000 sq. miles, slightly larger than Rhode Island.
The study was published Tuesday in the journal Communications Earth & Environment.
Seeing the amount of land dedicated to this use is important 'when you're thinking about how this affects communities living nearby, when you start to ask questions about water pollution, the size of the facility, questions about other health impacts,' said Joshua Newell, a geographer at the University of Michigan's School for Environment and Sustainability.
Once the researchers located the feed lots, they looked at local air quality and economic data, and found the operations are associated with degraded air quality, and the more land devoted to cattle and hog farms in a given census tract, the lower the social and economic well-being of people living nearby. A look at health-insurance coverage rates, for instance, shows they significantly drop in areas near cattle feeding operations.
Anja Raudabaugh, CEO of Western United Dairies — the state's largest dairy trade group — took issue with the study, and said the environmental and economic data were incorrect.
'The researchers either don't know, or failed to inquire, with the EPA or the local regulating air quality authorities about existing guardrails' on air pollution, she said.
She pointed out there are several other causes of or contributors to air pollution in the San Joaquin Valley, including Interstate 5 and Highway 99, as well as 'our significant and growing human population and geography that traps pollution in the valley.'
Newell responded that the analysis compared similar nearby tracts that are not right next to feeding operations — so other pollution sources were accounted for.
Last week, a federal court ruled animal feeding operations are exempt from reporting air emissions and dangerous 'pollutants' to local and state officials.
Raudabaugh also took issue with authors' claims about environmental justice, which she said were widely disputed in other research and analyses.
'We've discussed the real struggle of rural healthcare during recent viral outbreaks and how difficult it can be to service our communities,' she said, noting research about H5N1 bird flu and the vulnerability of a dairy workers to infection. 'But arriving at a single outcome, a production style of agriculture, is like saying L.A. has lots of cars and therefore a high homicide rate.'
Instead, she said, 'it would be nice to focus on increasing rural access to more healthcare where communities need it' instead of villainizing an industry that provides jobs and a 'major local tax base.'

A Surprising (and Easy) Way to Boost Your Attention Span
In 2008, 38 students at the University of Michigan set out on a walk. Half of them wound their way through the trees in Ann Arbor's Nichols Arboretum for 2.8 miles, while the other half navigated the same distance on the busy streets of downtown. A week later, the two groups swapped routes. Both times before they set out, the students took a test that challenged their attention and working memory, where they were given progressively longer sequences of numbers that they had to repeat back in reverse order. When they returned to campus, the students took the test again. Walking through town improved their performance slightly, but walking in nature boosted scores by nearly 20 percent. 'You didn't even need to like or enjoy the nature walk to get these cognitive benefits,' said Marc Berman, a professor of psychology at the University of Chicago, who conducted the study while he was a graduate student at Michigan. People who walked on a cold January day experienced just as much benefit as those who did the experiment in July. The effect that nature has on our minds has been studied many times before and since, and the research generally — though not always — finds that exposure to green spaces boosts our cognition and creativity, not to mention our mood. Many of us have experienced firsthand the natural world's ability to revitalize us — a moment of clarity after summiting a mountain, or renewed focus following a lunchtime stroll in the park. Scientists are trying to understand exactly why that happens. In his new book, 'Nature and the Mind,' Dr. Berman attributes the cognitive benefits of nature to 'attention restoration theory.' First proposed in the 1980s by Rachel and Stephen Kaplan (both of whom were psychology professors at the University of Michigan when Dr. Berman was a student there), the premise is that our ability to focus is a finite resource that gets easily used up, and being in nature is an effective way to replenish it.

A Pilot Is Pretty Sure He Found Amelia Earhart's Plane
Here's what you'll learn when you read this article: A pilot perusing Google Earth may have stumbled across the remnants of Amelia Earhart's plane. Inspired by a documentary on the Earhart's final flight, Justin Myers compared the measurements of anomalies in a Google Earth image to the components of her plane. So far, no major institutions have made any effort to investigate his claims. This story is a collaboration with Popular Mechanics. What would you do if you thought you'd cracked an unsolved mystery, but nobody wanted to listen? That's the predicament pilot Justin Myers currently finds himself in. With nearly a quarter-century in the air himself, he believes he's uncovered the answer to one of aviation's most enduring mysteries: Where is the wreckage of Amelia Earhart's Lockheed Electra 10E, the final plane she ever flew? All it took was Google Earth and a little curiosity. Unlike some who have tried to find the wreckage from Earhart and Fred Noonan's ill-fated final flight in 1937, Myers was not a life-long Earhart obsessive. 'To be totally honest,' Myers told Popular Mechanics, 'my interest started after watching a documentary on the National Geographic Channel. It was the next day when curiosity about Nikumaroro Island took me to looking on Google Earth.' Nikumaroro Island is often posited as a final resting place for, if not Earhart and Noonan themselves, than at least the Electra they were flying in. As Biography previously noted, 'This theory is based on several on-site investigations that have turned up artifacts such as improvised tools, bits of clothing, an aluminum panel and a piece of Plexiglas the exact width and curvature of an Electra window.' When Myers first looked up Nikumaroro, he wasn't initially looking for a plane at all. 'I was just putting myself in Amelia and Fred's shoes,' he told PopMech. But as he stared at those overhead images, he started to employ his own experience as a pilot, to think about 'where I would have force landed a light twin aircraft in their position, lost and low on fuel.' That's when Myers noticed what he felt were some anomalies on the map. He detailed his observations in a blog post: 'I picked an area which would probably have been what I thought to be best considering the circumstances. I zoomed in and there was a long sandy-looking shape... I measured the sandy section, which was over 50ft long, looked up the specifications of the Electra, and that measured 39ft.' Next to the sandy section, however, was a dark, straight object that was exactly 39 feet long. 'It looked man-made,' Myers noted as he continued to examine the object, 'it looked like a section of aircraft fuselage.' As Myers poured over the images more, he made out what appeared to him to be even more airplane debris, including what looked like a partially exposed radial engine, and his approximate measurements all aligned with the dimensions of the corresponding parts of the Lockheed Electra 10E that Earhart and Noonan had flown. But if these airplane parts could be seen from Google Earth images, why hadn't anyone seen them before? Myers suggested to PopMech that 'there was an element of luck in spotting that aircraft debris, as Mother Nature had revealed what had been buried on the reef for a long time. I managed to catch some photos before being covered over again by passing weather systems.' So, Myers assembled his images and his measurements, and was ready to present his findings. But just who do you present such a case to? 'I didn't know really where to go with this,' Myers wrote in his blog post. 'I wrote to the NTSB in the U.S., and they emailed me back saying it was not there [sic] jurisdiction, it was the ATSB, Australian Transport Safety Bureau. So, I filed an official report with the air crash investigation team in Brisbane.' But in the years since, there has been no real movement to take Myers' theory beyond the theoretical. 'I did have some communication with an expedition company in California,' Myers said to PopMech. 'However, I haven't heard anything in a long time. I also contacted Purdue University a few years ago and recently, but unfortunately they never responded.' So if Myers has found the solution to an enduring aeronautical quandary, why isn't anyone inquiring further? Well, in the case of Purdue University, it's not as though they're not pursuing answers to Earhart's disappearance at all. PopMech reported in July that they had announced their own expedition to investigate an anomaly known as the Taraia Object, often speculated to be the downed Electra. But it's also an impediment to Myers' outreach efforts that he is hardly alone in thinking he has found the final piece of the proverbial puzzle. If you had a dollar for every person who claimed to have found Amelia Earhart's plane, you'd probably have enough money to fund an expedition to try and find it. Hopes for answers have hinged on everything from old photographs to the promise of modern-day technology. In the process, some people with wildly different theories have become prominent figures in the aircraft recovery community, which has resulted in bitter feuds and sometimes even lawsuits. And of course, there's the risk of getting it wrong. In 2024, images from underwater drones operated by Tony Romeo's Deep Sea Vision showed 'contours that mirror the unique dual tails and scale' of the Lockheed Electra. At the time, Romeo had confidently stated that 'you'd be hard-pressed to convince me that this is not an airplane and not Amelia's plane.' But after another expedition was launched to more closely examine that anomaly, Romeo discovered that it was not an airplane but rather an ordinary rock formation. 'I'm super disappointed out here,' Romeo remarked after the fact, 'but you know, I guess that's life.' For his part, Myers isn't challenging others to convince him he's wrong, though he does feel confident, based on his measurements, that what he's found is more than just a naturally occurring phenomenon. 'The bottom line is,' he told PopMech, 'from my interests from a child in vintage aircraft and air crash investigation, I can say that is what was once a 12-metre, 2-engine vintage aircraft. What I can't say is that is definitely Amelia's Electra.' And if it isn't Amelia's place, PopMech asked, would Myers be disappointed? 'If this is not Amelia's Electra 10 E,' he said, 'then it's the answer to another mystery that has never been answered. This finding could answer some questions to someone who disappeared many years ago.' If Myers found Amelia Earhart's plane, it could bring him acclaim. But if it's a different downed plane he's found, it could at least bring closure to the family of whoever piloted it. Only time will tell if anyone with the funds to launch a search will take the leap of faith to see if there truly is a plane there at all.

California has more cattle feedlots than any state, new map shows
