Climate change has a cow and worm problem

Published

on

Cows with tummy troubles could be a big problem for the climate, a new study finds. That’s because cattle and other livestock with worms and other parasites produce more of the super potent greenhouse gas, methane, than healthy animals. Methane is 28 to 36 times more powerful than carbon dioxide when it comes to heating up the planet.

The amount of methane coming from cattle and other livestock was estimated to grow 20 percent from 2017 to 2050 by the United Nations Food and Agriculture Organization. But when parasitic worm infections are taken into consideration, the increase in methane could jump as high as 82 percent, according to a new paper published today in Trends in Ecology & Evolution.

That’s a large discrepancy, especially given how much domesticated livestock is already contributing to climate change. Livestock make up 60 percent of all the mammal biomass on Earth, and livestock industries are responsible for more than 14 percent of human-caused greenhouse gas emissions. (For comparison, aviation only accounts for about two percent of global emissions.)

What’s even more worrying is that there could be a dangerous feedback loop between climate change, parasitic diseases, and higher methane emissions: Animals infected with parasitic worms and bacteria push out more methane over the course of their lives, which accelerates climate change. Parasites that infect livestock can thrive in warmer temperatures, infecting even more animals, and then the vicious cycle continues.

“That could be a really interesting phenomenon, or an important one that we’re not really considering,” says Vanessa Ezenwa, lead author of the paper and professor of ecology at the University of Georgia.

Infected or not, cows and other hoofed herbivores, called ruminants, are at the top of the methane-emitting heap. Other animals (including people) emit methane, too, but ruminants burp out more of the gas because of their four-chambered stomachs. They have an entire chamber for fermenting food, where microbes that help them digest tough foods pump out a lot of planet-heating gasses. “It’s magnified for them, compared to us,” Ezenwa says.

Parasitic infections can lead to a number of changes that could increase methane emissions from livestock. The animals grow more slowly, which leads to more lifetime emissions since it takes longer for them to develop enough to slaughter for meat. An infection can also reduce milk production, making dairy farming less efficient. Ranchers might decide to cull and replace their cattle more frequently, and evidence suggests that this usually leads to more animals (and more emissions) rather than less.

At the extreme end of the scenarios offered in the paper, if every animal got sick, methane emissions from livestock would rise by 52 percent globally, according to the study authors. To calculate this, Ezenwa and her colleagues reviewed existing research on the effects of parasitic infections on methane production in specific animals. They used those findings to figure out what the potential global impact is on methane emissions. Data from the UN Food and Agriculture Organization served as a baseline.

There are some limitations to the study, which provides estimates rather than hard figures. The researchers used a sliding scale of potential infection prevalence since they didn’t have an actual global rate for parasitic infections. The real-world numbers can vary dramatically from region to region and there are gaps in data.

The results of the new study aren’t necessarily surprising, according to Ermias Kebreab, director of the World Food Center at the University of California, Davis. Kebreab was not involved in the study. “It is common sense,” he says.

The research might be most helpful in low to middle-income countries where parasitic infections are more common, Kebraeb points out. North America and Europe have boosted the productivity of livestock by better controlling pathogens, he says.

“This is a good article to help us remember that there’s a compounding issue,” Kebraeb says.

Parasitic worms that cause problems for cows develop outside before infecting a host. Some of these worms need warmer temperatures to thrive, according to Ezenwa. As climate change makes winters milder and summers longer in some regions, these parasites have more time to develop and infect livestock, she says.

Ultimately, the new study shows the need for more research to inform efforts to tackle the climate crisis. That could have a string of benefits: healthier animals and a healthier world for all of us to live in.

Best Tech DealsBest Tech DealsThe best tech deals from around the web, updated daily.

Apple AirPods Pro | $200 | Amazon
Apple AirPods Pro | $200 | B&H Photo

If you’re an iPhone user with some cash to blow, skip the pretenders and even the lesser AirPods to go for something better. The AirPods Pro stepped the game up with rubber tips, noise cancellation, and better overall audio quality. They’re a bit expensive and the price has dropped bit by bit over time, leading up to today’s opportunity to save $50 on a pair of your own, complete with a wireless charging case. With active noise canceling, automatic pairing on iPhones and iPads, and water/sweat resistance, picking ‘em now is a no-brainer if you were already in the market for them.

We saw these drop just before Amazon Prime Day, and the price has held steady since. However, B&H Photo has a similar offer that’s set to expire October 30, which may be a signal that the opportunity is about to pass. Be sure to get your order in while there’s still time!

In his roundup of the best VPNs at Gizmodo, Andrew Couts called NordVPN “fast and easy to use,” citing accessibility and affordability as reasons to subscribe. Though it’s almost always marked down from its $287 list price, the 2-year plan is nonetheless the cheapest option to get started with the service and continue using it long-term. For a limited time only, though, it’s not only 68% off, bringing your total to just $89 for 730 days, but it also comes with an extra plan on top of that—chosen at random by the Nordic gods. Couts says in his abbreviated review:

No matter what you pay, you’ll get access to more than 5,400 servers in more than 60 countries, a bunch of features you may or may not want, and, because the company is based in Panama, assurances that your data—or lack of data, as the case may be—is outside of U.S. and European jurisdictions. Like every other VPN on this list, NordVPN claims to have a “strict no-logs policy,” so most of your data isn’t collected, the company says. It does still collect your email address, payment information, and the timestamp of the last time you launched the VPN.

But NordVPN isn’t without its downsized. “…some researchers have found that it sends your email address and Google Ad ID to a marketing company when you register through the Android app and contains some trackers,” Couts explains. “Another downside is that some of NordVPN’s servers are rented, which means another company you need to trust is in the mix. And yes, one of those servers got hacked in 2018.”

Still, if you want the one of the most reliable VPN clients, with the budget to support its robust infrastructure, you can’t go wrong with NordVPN. Plus, with availability on virtually every platform you can think of—from macOS to Android TV—it’s equal parts ubiquitous and acclaimed. Endorsed by PCMag, Wired, CNET, Business Insider, and more, it may be time to board the Nord hype train if you’re somehow unwedded to a VPN already.

Sony’s new WH-1000XM4 headphones are leading the way in their noise-cancellation technology, alongside the gestures that come with these new models. They were down to $298 during Prime Day and $284 at Newegg just a couple of weeks ago, but BuyDig is piledriving the competition with a $278 sticker price today.

They will pause the track once it detects you’re speaking, and will also switch off the noise-cancellation when a hand is put on the right-cup. They feature fantastic sound and are able to be paired for up to two devices, so you can switch between your phone and your tablet with ease.

Though they’re mostly for keeping things clean, even towels get dirty eventually. Sure, it might’ve started as a way to rinse off after a shower karaoke sesh, but eventually that white will start to fade and might not look as nice hanging up. Or maybe after a few too many pup accidents in the house, it’s just time for a new set of linens.

Huckberry’s Turkish towels usually sell for a bit over $40, but right now they’re down to just below $30, and you’re getting some pretty fancy looking towels for your money. The striped towels come in plenty of variants to match your decor, and their unique design will certainly earn a few compliments if we’re ever safe to have people over.
