Sun Basket Meal Delivery Sets a High Bar for Healthy, Sustainable Eating
Sun Basket
There are a lot of meal delivery companies out there, and while most of them offer great food for a decent price, not all meal delivery companies are created equal with regard to sustainability practices. Enter Sun Basket, a meal delivery company that truly makes it easy to cook responsibly: Not only does the company offer a host of clean and organic food options, but they also set a high bar when minimizing their environmental footprint.
In this article, we'll tell you everything you need to know about the sustainable home cooking options that are available through Sun Basket.
Sun Basket Meal Delivery: Company Overview
It's impossible to talk about Sun Basket without mentioning Justine Kelly, aka Chef Justine. As Sun Basket's executive chef, she's the one who develops each recipe and ensures wholesome, delicious flavors in every box that's delivered.
Chef Justine has an amazing track record that includes a role at Slanted Door, an award-winning restaurant in the San Francisco area. From her time in the restaurant world to her current role at Sun Basket, Chef Justine has developed a strong reputation for championing the very best, most sustainably sourced produce, seafood, and meats.
She has brought her commitment to healthy, environmentally responsible, and farmer-friendly cuisine to Sun Basket, a meal delivery service that's defined by its very admirable corporate values:
- First and foremost, the company is devoted to meals that taste good, relying on clean and high-quality ingredients.
- Sun Basket is a certified organic handler, and is committed to providing patrons with ingredients that are well-sourced and 100 percent organic, all the time.
- The company offers meal plans that accommodate a range of lifestyles and dietary choices, including paleo, vegetarian, gluten-free, and more.
- Sun Basket champions sustainability, from its compostable packaging to its partnerships with eco-friendly farms and fishermen.
These are just some of the reasons why Sun Basket stands out from other meal delivery services. Now, let's take a closer look at how some of these values play out day-to-day.
Sun Basket’s Sustainability Practices
There are a number of ways in which Sun Basket proves its commitment to sustainability, starting with its partnerships with farmers, fishermen, and ranchers:
- Chef Justine has always been known for ensuring thoughtful partnerships with local agriculturalists, and she's brought that ethos to Sun Basket. The company is steadfast and judicious in sourcing farms, partners who pioneer sustainable practices such as crop rotation and water efficiency.
- Similarly, the Sun Basket team shows great care in the fishermen they choose to work with, only selecting seafood providers who ensure low-impact fishing methods that preserve natural populations and ecosystems.
- Sun Basket also sources its meat from ranches that treat animals with respect. (They provide only antibiotic- and hormone-free meat, and organic eggs).
These are just a few examples of how Sun Basket ensures that its wholesome and delicious meals also promote good stewardship of the environment.
Corporate Citizenship at Sun Basket
Additionally, make note of the ways in which Sun Basket demonstrates responsible corporate citizenship.
Specifically, Sun Basket does a lot to give back and to reinvest in local communities. It does so through a partnership with Feeding America, as well as key relationships with local food banks. They also have various employee programs that allow them to be a force of good in the world.
This, combined with their support for independent and sustainable farms, shows that Sun Basket is serious about modeling good corporate citizenship. Simply put, this is a company you'll likely be able to support without qualms of conscience.
Sun Basket Values
What About Packaging and Recycling?
One specific concern about sustainability is packaging. After all, Sun Basket delivers meals in a box, which can't help but produce a lot of physical waste. What steps do they take to ensure eco-friendly packaging?
- All Sun Basket packaging is recyclable and/or compostable.
- Sun Basket also lists a lot of ways in which their boxes can be reused around your home.
- Reclaimed denim is used as insulation.
- Ice packs may also be reused in various ways.
Another note: According to Sun Basket, making trips to the grocery store each week creates far more greenhouse gas emissions than using a meal delivery service. Also be aware that, by getting pre-set meals, the likelihood of food waste or ingredient spoilage is quite low.
Sun Basket Meal Delivery Pricing
A final topic for consideration is pricing.
- Recipes cost anywhere from $11 to $13 per serving; the price goes down depending on how many recipes you opt to get each week.
- You may also choose to get either two or four servings with each recipe.
- An order may be as low as $52 per week, or as high as $175; again, the price is determined by serving number and recipe number.
The Bottom Line
Over the past several years, home cooking has made a big resurgence… with a contemporary twist. Thanks to the rise of meal delivery services, anyone who wants to make their own meals at home can do so, with relative ease. Most of these services work in roughly the same way: They allow you to denote some basic dietary preferences, as well as the frequency with which you'd like to receive your meals. Each meal is then shipped in a box, with all the ingredients you need as well as clear, accessible instructions. You can then make your own delicious meals without the hassle of recipe sourcing, going to the market, or ensuring the right quantity of ingredients.
Sun Basket isn't the only meal delivery service out there, but it may be the most impressive with regard to its commitment to eco-friendliness, sustainable agriculture, and astute corporate citizenship. That their meals are also filling, delicious, creative, and reasonably priced only makes the company more appealing.
If you're looking for a way to cook at home more regularly, and with less impact on the environment, Sun Basket is a meal delivery service that deserves your attention.

Cities Can Help Migrating Birds on Their Way By Planting More Trees and Turning Lights Off at Night

Animals
By Frank La Sorte and Kyle Horton
Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean and South America.

<p>For many species, these journeys take place at night, when skies typically are calmer and predators are less active.

<p>We used this information to determine how the number of migratory bird species varies based on each city's level of <a href="https://www.britannica.com/science/light-pollution" target="_blank" rel="noopener noreferrer">light pollution</a> – brightening of the night sky caused by artificial light sources, such as buildings and streetlights. We also explored how species numbers vary based on the quantity of tree canopy cover and impervious surface, such as concrete and asphalt, within each city. Our findings show that cities can help migrating birds by planting more trees and reducing light pollution, especially during spring and autumn migration.</p>Declining Bird Populations
<p>Urban areas contain numerous dangers for migratory birds. The biggest threat is the risk of <a href="https://doi.org/10.1650/CONDOR-13-090.1" target="_blank">colliding with buildings or communication towers</a>. Many migratory bird populations have <a href="http://dx.doi.org/10.1126/science.aaw1313" target="_blank">declined over the past 50 years</a>, and it is possible that light pollution from cities is contributing to these losses.</p><p>Scientists widely agree that light pollution can <a href="https://doi.org/10.1073/pnas.1708574114" target="_blank">severely disorient migratory birds</a> and make it hard for them to navigate. Studies have shown that birds will cluster around brightly lit structures, much like insects flying around a porch light at night. Cities are the <a href="https://doi.org/10.1002/fee.2029" target="_blank" rel="noopener noreferrer">primary source of light pollution for migratory birds</a>, and these species tend to be more abundant within cities <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.13792" target="_blank" rel="noopener noreferrer">during migration</a>, especially in <a href="https://doi.org/10.1016/j.landurbplan.2020.103892" target="_blank" rel="noopener noreferrer">city parks</a>.</p><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ1OTYyNC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0Nzk5NTUwOH0.h8aA9ZJUJvLbHP82CVZAOkYcY54eljqMy4rrMaunO9M/img.jpg?width=980" id="608a8" class="rm-shortcode" data-rm-shortcode-id="3da85b14a1c03abfd4f95c00439fb36e" data-rm-shortcode-name="rebelmouse-image" data-width="1000" data-height="640" />

The Power of Citizen Science
<p>It's not easy to observe and document bird migration, especially for species that migrate at night. The main challenge is that many of these species are very small, which limits scientists' ability to use electronic tracking devices.</p><p>With the growth of the internet and other information technologies, new data resources are becoming available that are making it possible to overcome some of these challenges. <a href="https://doi.org/10.1038/d41586-018-07106-5" target="_blank">Citizen science initiatives</a> in which volunteers use online portals to enter their observations of the natural world have become an important resource for researchers.</p><p>One such initiative, <a href="https://ebird.org/home" target="_blank" rel="noopener noreferrer">eBird</a>, allows bird-watchers around the globe to share their observations from any location and time. This has produced one of the <a href="https://doi.org/10.1111/ecog.04632" target="_blank" rel="noopener noreferrer">largest ecological citizen-science databases in the world</a>. To date, eBird contains over 922 million bird observations compiled by over 617,000 participants.</p><span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="59e33da8efe0bf60f7bda00b06e1f4e2"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/StF19Qdgqn0?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p><em>Large clusters of birds (blue and green splotches) captured by weather radar during spring migration, April-May 2019.</em></p>
Light Pollution Both Attracts and Repels Migratory Birds
<p>Migratory bird species have evolved to use certain migration routes and types of habitat, such as forests, grasslands or marshes. While humans may enjoy seeing migratory birds appear in urban areas, it's generally not good for bird populations. In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. As scientists, we're concerned when we see evidence that migratory birds are being drawn away from their traditional migration routes and natural habitats.</p><p>Through our analysis of eBird data, we found that cities contained the greatest numbers of migratory bird species during spring and autumn migration. Higher levels of light pollution were associated with more species during migration – evidence that light pollution attracts migratory birds to cities across the U.S. This is cause for concern, as it shows that the influence of light pollution on migratory behavior is strong enough to increase the number of species that would normally be found in urban areas.</p><p>In contrast, we found that higher levels of light pollution were associated with fewer migratory bird species during the summer and winter. This is likely due to the scarcity of suitable habitat in cities, such as large forest patches, in combination with the adverse affects of light pollution on bird behavior and health. In addition, during these seasons, migratory birds are active only during the day and their populations are largely stationary, creating few opportunities for light pollution to attract them to urban areas.</p><span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="19d2d2bc77cd31e4374fd12cdadbe4bf"><iframe lazy-loadable="true" src="https://www.youtube.com/embed/08ET47-b13o?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p><em><strong></strong>Darkening skies at night during migration season makes it easier for birds to navigate.</em></p>
Trees and Pavement
<p>We found that tree canopy cover was associated with more migratory bird species during spring migration and the summer. Trees provide important habitat for migratory birds during migration and the breeding season, so the presence of trees can have a strong effect on the number of migratory bird species that occur in cities.</p><p>Finally, we found that higher levels of impervious surface were associated with more migratory bird species during the winter. This result is somewhat surprising. It could be a product of the <a href="https://www.epa.gov/heatislands" target="_blank">urban heat island effect</a> – the fact that structures and paved surfaces in cities absorb and reemit more of the sun's heat than natural surfaces. Replacing vegetation with buildings, roads and parking lots can therefore make cities significantly warmer than surrounding lands. This effect could reduce cold stress on birds and increase food resources, such as insect populations, during the winter.</p><p>Our research adds to our understanding of how conditions in cities can both help and hurt migratory bird populations. We hope that our findings will inform urban planning initiatives and strategies to reduce the harmful effects of cities on migratory birds through such measures as <a href="https://www.arborday.org/programs/treecityusa/index.cfm" target="_blank" rel="noopener noreferrer">planting more trees</a> and initiating <a href="https://aeroecolab.com/uslights" target="_blank" rel="noopener noreferrer">lights-out programs</a>. Efforts to make it easier for migratory birds to complete their incredible journeys will help maintain their populations into the future.</p><p><em><span style="background-color: initial;"><a href="https://theconversation.com/profiles/frank-la-sorte-1191494" target="_blank">Frank La Sorte</a> is a r</span>esearch associate at the </em><em>Cornell Lab of Ornithology, Cornell University. <a href="https://theconversation.com/profiles/kyle-horton-1191498" target="_blank">Kyle Horton</a> is an assistant professor of Fish, Wildlife, and Conservation Biology at the Colorado State University.</em></p><p><em></em><em>Disclosure statement: Frank La Sorte receives funding from The Wolf Creek Charitable Foundation and the National Science Foundation (DBI-1939187).

Editor's note: This story is part of a nine-month investigation of drinking water contamination across the U.S. The series is supported by funding from the Park Foundation and Water Foundation. Read the launch story, "Thirsting for Solutions," here.
In late September 2020, officials in Wrangell, Alaska, warned residents who were elderly, pregnant or had health problems to avoid drinking the city's tap water — unless they could filter it on their own.
<p style="">More than 3,000 miles (4,800 kilometers) away, the people of <a href="https://www.documentcloud.org/documents/7208933-Scituate-Water-Notification-9-10-2020.html" rel="noopener noreferrer" target="_blank">Scituate, Massachusetts</a>, received a letter that same month cautioning about the same group of contaminants in their <a href="https://www.ecowatch.com/tag/drinking-water">drinking water</a>.</p>
<p>At issue wasn't any of the well-known and widely feared water infiltrators such as <em>E. coli </em>or <a href="https://ensia.com/features/drinking-water-contamination-pfas-health/" target="_blank">per- and polyfluoroalkyl substances (PFAS)</a>. The culprit chemicals tainting taps from <a href="https://www.floridatoday.com/story/news/local/environment/2016/05/31/elevated-disinfection-byproducts-taint-cocoa-water/85184636/" target="_blank">Cocoa, Florida</a>, to the <a href="https://auburnpub.com/news/local/several-cayuga-county-water-systems-violate-standard-for-chlorination-byproduct/article_d5568ecc-edd0-55b1-a858-37aaf2b1c82f.html" target="_blank">Finger Lakes of New York</a> to a correctional facility in <a href="https://www.jdsupra.com/legalnews/drinking-water-enforcement-tennessee-98500/" target="_blank">Only, Tennessee</a>, are, in fact, less recognized yet more ubiquitous: disinfection by-products.</p><p>"Take a glass of water. You may or may not have pesticides, pharmaceuticals, PFAS and lead in it. Usually not," says Susan Richardson, a professor of biochemistry at the University of South Carolina in Columbia. "But there's always something that is in your drinking water, and that's disinfection by-products."</p><p>Aptly named, the chemicals form in water when disinfectants that are widely used to kill pathogens in municipal drinking water facilities react with organic compounds. These compounds may be present in the water as a result of natural processes such as the decay of leaves and animal matter, as well as human activities that may release solvents, pharmaceuticals, pesticides and industrial chemicals. Exposure to disinfection by-products through drinking, bathing or <a href="https://pubs.acs.org/doi/abs/10.1021/acs.est.6b00808" target="_blank">swimming</a> has been linked to potential <a href="https://www.sciencedirect.com/science/article/abs/pii/S2213343720302876" target="_blank" rel="noopener noreferrer">increased risks</a> of <a href="https://www.ewg.org/childrenshealth/23264/study-disinfection-byproducts-drinking-water-may-increase-risk-low-birth" target="_blank" rel="noopener noreferrer">low birthweight babies</a>, birth defects, <a href="https://pubmed.ncbi.nlm.nih.gov/29676755/" target="_blank" rel="noopener noreferrer">miscarriages</a> and <a href="https://ehp.niehs.nih.gov/doi/full/10.1289/EHP4495" target="_blank" rel="noopener noreferrer">cancer</a>.</p><p>"Disinfection is hugely important. We've got to kill those pathogens," says Richardson. "We had millions of people dying from waterborne illnesses before we started disinfecting water in the 1800s."</p>

Still today, when concentrations of disinfectants fall too low, drinking water can become a breeding ground for dangerous pathogens such as <a href="https://ensia.com/features/legionella-pathogens-drinking-water/" target="_blank">Legionella</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/12638998/" target="_blank"><em>E. coli</em></a><em>, </em>even <a href="https://www.nytimes.com/1991/04/19/world/cholera-kills-1100-in-peru-and-marches-on-reaching-the-brazilian-border.html" target="_blank">cholera</a>.</p><p>"It's a trade-off between inactivating pathogens that are going to make people sick today versus the long-term, low-level risk of chemicals in the water," says Christy Remucal, an associate professor of civil and environmental engineering at the University of Wisconsin–Madison.</p><p><a href="https://www.sciencedirect.com/science/article/abs/pii/S2213343720302876" target="_blank">Striking a balance</a> may be even more challenging today as waters become increasingly compromised due to population growth, wastewater intrusion, energy exploration, climate change — and now the Covid-19 pandemic, according to Richardson.</p><p>During the pandemic, many places have increased use of chlorine for disinfection in indoor and outdoor settings and during wastewater treatment, resulting in the potential for higher levels of disinfection by-products. Authors of a <a href="https://pubs.acs.org/doi/10.1021/acs.est.0c04394" target="_blank" rel="noopener noreferrer">study</a> published in October warn that this "upsurge and overuse of chlorine-based disinfectants" may pose a threat to human health "by impacting water quality."</p><p>Concentrations of harmful chemicals have also likely increased in buildings left vacant during Covid-19 shutdowns. The longer that water sits in pipes, explains Richardson, the longer it has to react with disinfectants and form more by-products.</p><p>Still, Gregory Korshin, a professor of civil and environmental engineering at the University of Washington in Seattle, encourages perspective on the issue of disinfection by-products. The answer, he and others say, is not to stop disinfecting water, nor is it for everyone to buy bottled water.</p><p>"There is a dark side of disinfection," adds Korshin. "But this doesn't compromise the notion that drinking water in the U.S. is safe."</p>
Unintended Consequences
<p>Chemists first discovered disinfection by-products in treated drinking water in the 1970s. The trihalomethanes they found, they determined, had resulted from the reaction of chlorine with natural organic matter. Since then, scientists have identified more than 700 additional disinfection by-products. "And those only represent a portion. We still don't know half of them," says Richardson, whose lab has identified hundreds of disinfection by-products. </p><p>Identification of disinfection by-products is incredibly difficult, she explains, because these chemicals are not simply flowing down a river from an industrial site or running off a farm. "They didn't exist before," she adds. "It's a complete unknown — there's no preconceived idea of what these chemicals look like."</p><p>Another research team recently discovered more previously unidentified disinfection by-products. As they described in a January 2020 <a href="https://pubs.acs.org/doi/abs/10.1021/acs.est.9b04926" target="_blank">study</a>, potentially carcinogenic chemicals are formed through the interaction of chlorine and not only organic matter in the environment but also manmade materials that include phenols such as <a href="https://ensia.com/features/what-will-it-take-to-rid-our-store-shelves-of-bpa/" target="_blank" rel="noopener noreferrer">bisphenol A (BPA)</a> and other plasticizers, as well as sunscreen agents and antimicrobials.</p><p>"These phenol compounds are incredibly widespread because of their properties," says Carsten Prasse, a coauthor on the study and an assistant professor of environmental health and environmental engineering at Johns Hopkins University. He highlights their use in both plastic pipes and plastic bottles, which frequently carry drinking water.</p>
What’s Regulated and What’s Not?
<p>The U.S. Environmental Protection Agency (EPA) currently regulates 11 disinfection by-products — including a handful of trihalomethanes (THM) and haloacetic acids (HAA). While these represent only a small fraction of all disinfection by-products, EPA aims to use their presence to indicate the presence of other disinfection by-products. "The general idea is if you control THMs and HAAs, you implicitly or by default control everything else as well," says Korshin.</p><p>EPA also requires drinking water facilities to use techniques to reduce the concentration of organic materials before applying disinfectants, and regulates the quantity of disinfectants that systems use. These rules ultimately can help control levels of disinfection by-products in drinking water.</p><a href="https://www.ewg.org/tapwater/reviewed-disinfection-byproducts.php" target="_blank"><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ1OTg1OC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0MzYyNTAwNX0.1IaCMF-b4X9jtCSFsZuQfRvQCO54EqgfRcGulUoMP10/img.jpg?width=980" id="36d2f" class="rm-shortcode" data-rm-shortcode-id="e8502b4c0de9cbd99651d4978548af81" data-rm-shortcode-name="rebelmouse-image" data-width="1144" data-height="1036" /></a>

<p>Still, some scientists and advocates argue that current regulations do not go far enough to protect the public. Many question whether the government is regulating the right disinfection by-products, and if water systems are doing enough to reduce disinfection by-products. EPA is now seeking public input as it considers potential revisions to regulations, including the possibility of regulating additional by-products. The agency held a <a href="https://www.epa.gov/dwsixyearreview/potential-revisions-microbial-and-disinfection-byproducts-rules" target="_blank">two-day public meeting</a> in October 2020 and plans to hold additional public meetings throughout 2021.</p><p>When EPA set regulations on disinfection by-products between the 1970s and early 2000s, the agency, as well as the scientific community, was primarily focused on by-products of reactions between organics and chlorine — historically the most common drinking water disinfectant. But the science has become increasingly clear that these chlorinated chemicals represent a fraction of the by-product problem.</p><p>For example, bromide or iodide can get caught up in the reaction, too. This is common where seawater penetrates a drinking water source. By itself, bromide is innocuous, says Korshin. "But it is extremely [reactive] with organics," he says. "As bromide levels increase with normal treatment, then concentrations of brominated disinfection by-products will increase quite rapidly."</p><p><a href="https://pubmed.ncbi.nlm.nih.gov/15487777/" target="_blank">Emerging</a> <a href="https://pubs.acs.org/doi/10.1021/acs.est.7b05440" target="_blank" rel="noopener noreferrer">data</a> indicate that brominated and iodinated by-products are potentially more harmful than the regulated by-products.</p><p>Almost half of the U.S. population lives within 50 miles of either the Atlantic or Pacific coasts, where saltwater intrusion can be a problem for drinking water supplies. "In the U.S., the rule of thumb is the closer to the sea, the more bromide you have," says Korshin, noting there are also places where bromide naturally leaches out from the soil. Still, some coastal areas tend to be spared. For example, the city of Seattle's water comes from the mountains, never making contact with seawater and tending to pick up minimal organic matter.</p><p>Hazardous disinfection by-products can also be an issue with desalination for drinking water. "As <a href="https://ensia.com/features/can-saltwater-quench-our-growing-thirst/" target="_blank" rel="noopener noreferrer">desalination</a> practices become more economical, then the issue of controlling bromide becomes quite important," adds Korshin.</p>Other Hot Spots
<p>Coastal areas represent just one type of hot spot for disinfection by-products. Agricultural regions tend to send organic matter — such as fertilizer and animal waste — into waterways. Areas with warmer climates generally have higher levels of natural organic matter. And nearly any urban area can be prone to stormwater runoff or combined sewer overflows, which can contain rainwater as well as untreated human waste, industrial wastewater, hazardous materials and organic debris. These events are especially common along the East Coast, notes Sydney Evans, a science analyst with the nonprofit Environmental Working Group (EWG, a collaborator on <a href="https://ensia.com/ensia-collections/troubled-waters/" target="_blank">this reporting project</a>).</p><p>The only drinking water sources that might be altogether free of disinfection by-products, suggests Richardson, are private wells that are not treated with disinfectants. She used to drink water from her own well. "It was always cold, coming from great depth through clay and granite," she says. "It was fabulous."</p><p>Today, Richardson gets her water from a city system that uses chloramine.</p>Toxic Treadmill
<p>Most community water systems in the U.S. use chlorine for disinfection in their treatment plant. Because disinfectants are needed to prevent bacteria growth as the water travels to the homes at the ends of the distribution lines, sometimes a second round of disinfection is also added in the pipes.</p><p>Here, systems usually opt for either chlorine or chloramine. "Chloramination is more long-lasting and does not form as many disinfection by-products through the system," says Steve Via, director of federal relations at the American Water Works Association. "Some studies show that chloramination may be more protective against organisms that inhabit biofilms such as Legionella."</p><p>If a drinking water facility fails to meet EPA regulations for disinfection by-products, one relatively easy and cheap modification is to add ammonia to the existing treatment, turning chlorine to chloramine. Many large community water systems in the U.S. now use chloramine. By doing so, according to Richardson, they have dropped levels of regulated disinfection by-products by up to as much as 90%.</p><p>However, there is one major drawback to this shift: the creation of potentially more harmful by-products. "It might push down on regulated disinfection by-products, but then other things pop up that are even more toxic," says Richardson, whose research team discovered previously unknown disinfection by-products in chloraminated drinking water. One of those finds, <a href="https://pubs.acs.org/doi/10.1021/es304786b" target="_blank">iodoacetic acid</a>, is the <a href="https://pubmed.ncbi.nlm.nih.gov/30919613/" target="_blank" rel="noopener noreferrer">most DNA-damaging disinfection by-product</a> known to date.</p><p>Prasse underscored the concern: "From a regulatory perspective, we could say we're fine. But it's a false sense of security."</p><p>Rather than continuing on the toxic treadmill of replacing one potentially toxic chemical for another, a more effective solution may be to focus upstream in the treatment process — such as keeping organics out of the system in the first place. "That requires engineers, chemists, toxicologists and regulators to come together and figure something out," says Prasse.</p>
Alternative Approaches
<p>When he moved to the U.S. from Germany, Prasse says he immediately noticed the bad taste of the water. "You can taste the chlorine here. That's not the case in Germany," he says.</p><p>In his home country, water systems use chlorine — if at all — at lower concentrations and at the very end of treatment. In the Netherlands, <a href="https://dwes.copernicus.org/articles/2/1/2009/dwes-2-1-2009.pdf" target="_blank">chlorine isn't used at all</a> as the risks are considered to outweigh the benefits, says Prasse. He notes the challenge in making a convincing connection between exposure to low concentrations of disinfection by-products and health effects, such as cancer, that can occur decades later. In contrast, exposure to a pathogen can make someone sick very quickly.</p><p>But many countries in Europe have not waited for proof and have taken a precautionary approach to reduce potential risk. The emphasis there is on alternative approaches for primary disinfection such as ozone or <a href="https://www.pbs.org/wgbh/nova/article/eco-friendly-way-disinfect-water-using-light/" target="_blank" rel="noopener noreferrer">ultraviolet light</a>. Reverse osmosis is among the "high-end" options, used to remove organic and inorganics from the water. While expensive, says Prasse, the method of forcing water through a semipermeable membrane is growing in popularity for systems that want to reuse wastewater for drinking water purposes.</p><p>Remucal notes that some treatment technologies may be good at removing a particular type of contaminant while being ineffective at removing another. "We need to think about the whole soup when we think about treatment," she says. What's more, Remucal explains, the mixture of contaminants may impact the body differently than any one chemical on its own. </p><p>Richardson's preferred treatment method is filtering the water with granulated activated carbon, followed by a low dose of chlorine.</p><p>Granulated activated carbon is essentially the same stuff that's in a household filter. (EWG recommends that consumers use a <a href="https://www.ewg.org/tapwater/reviewed-disinfection-byproducts.php#:~:text=EWG%20recommends%20using%20a%20home,as%20trihalomethanes%20and%20haloacetic%20acids." target="_blank" rel="noopener noreferrer">countertop carbon filter</a> to reduce levels of disinfection by-products.) While such a filter "would remove disinfection by-products after they're formed, in the plant they remove precursors before they form by-products," explains Richardson. She coauthored a <a href="https://pubs.acs.org/doi/10.1021/acs.est.9b00023" target="_blank" rel="noopener noreferrer">2019 paper</a> that concluded the treatment method is effective in reducing a wide range of regulated and unregulated disinfection by-products.</p><br><img lazy-loadable="true" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ1OTg2MC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0MjI3OTk2NX0.XuxufjUTyOygRCpgnG2jXqOIy4isl7Vz1QlnMmKSyHM/img.jpg?width=980" id="003a3" class="rm-shortcode" data-rm-shortcode-id="0da178217c0a9dd4c3c880e1c05a86f9" data-rm-shortcode-name="rebelmouse-image" data-width="1144" data-height="312" />
Greater Cincinnati Water Works installed a granulated activated carbon system in 1992, and is still one of relatively few full-scale plants that uses the technology. Courtesy of Greater Cincinnati Water Works.
<p>Despite the technology and its benefits being known for decades, relatively few full-scale plants use granulated active carbon. They often cite its high cost, Richardson says. "They say that, but the city of Cincinnati [Ohio] has not gone bankrupt using it," she says. "So, I'm not buying that argument anymore."</p><p>Greater Cincinnati Water Works installed a granulated activated carbon system in 1992. On a video call in December, Jeff Swertfeger, the superintendent of Greater Cincinnati Water Works, poured grains of what looks like black sand out of a glass tube and into his hand. It was actually crushed coal that has been baked in a furnace. Under a microscope, each grain looks like a sponge, said Swertfeger. When water passes over the carbon grains, he explained, open tunnels and pores provide extensive surface area to absorb contaminants.</p><p>While the granulated activated carbon initially was installed to address chemical spills and other industrial contamination concerns in the Ohio River, Cincinnati's main drinking water source, Swertfeger notes that the substance has turned out to "remove a lot of other stuff, too," including <a href="https://ensia.com/features/drinking-water-contamination-pfas-health/" target="_blank" rel="noopener noreferrer">PFAS</a> and disinfection by-product precursors.</p><p>"We use about one-third the amount of chlorine as we did before. It smells and tastes a lot better," he says. "The use of granulated activated carbon has resulted in lower disinfection by-products across the board."</p><p>Richardson is optimistic about being able to reduce risks from disinfection by-products in the future. "If we're smart, we can still kill those pathogens and lower our chemical disinfection by-product exposure at the same time," she says.</p><p><em>Reposted with permission from </em><em><a href="https://ensia.com/features/drinking-water-disinfection-byproducts-pathogens/" target="_blank">Ensia</a>. </em><a href="https://www.ecowatch.com/r/entryeditor/2649953730#/" target="_self"></a></p>

Eat Just's cell-based chicken nugget is now served at Singapore restaurant 1880. Eat Just, Inc.
At a time of impending global food scarcity, cell-based meats and seafood have been heralded as the future of food.
<p>This cell-based industry is where scientists, environmentalists and food technology companies intersect to offer more sustainable ways to feed the world's growing population. The high-tech food innovations take "the animal out of the meat" and create "seafood without the sea," respectively coined by <a href="https://newatlas.com/lab-grown-meat-public-attitudes/48921/?itm_source=newatlas&itm_medium=article-body" target="_blank">New Atlas</a> and <a href="https://www.npr.org/sections/thesalt/2019/05/05/720041152/seafood-without-the-sea-will-lab-grown-fish-hook-consumers" target="_blank">NPR</a>. These products — real meat and seafood — are originally cultured from animal cells but made without the actual animal. Because of this, many of the personal and global concerns about safety, ethics and the environment can be avoided without sacrificing food preferences.</p><p>Two leading industry examples are Eat Just and BlueNalu. Last month, Singapore issued San Francisco-based Eat Just the <a href="https://www.ecowatch.com/lab-grown-chicken-approved-singapore-2649108790.html" target="_self">world's first regulatory approval for cell-based meat</a>. The "chicken nuggets" are now available at downtown Singapore restaurant 1880. Meanwhile, San Diego's BlueNalu has pioneered "cellular aquaculture" to create cell-based seafood fillets from fish, including yellowtail, mahi-mahi, red snapper and tuna. In mid-2020, the company increased its research and development facilities six-fold after completing a $20 million funding round, <a href="https://thefishsite.com/articles/blue-nalu-set-for-6-fold-expansion" target="_blank">The Fish Site</a> reported. These two companies are pushing the industry to the next level with key regulatory developments and new innovations.</p><h3>The Science Behind Cell-Based</h3><p>In a nutshell, this is how cell-based food works: muscle stem cells are obtained from an actual animal, like chicken or fish, and cultivated in steel tanks with the same nutrients that living animals consume. The goal is not to grow a full animal, so the end result doesn't include the head, tail or heart, for example, while the original cell donor isn't sacrificed. The harvested cells multiply and are shaped to form meat or fish that cooks, looks and tastes just like its real counterpart.</p><p>"The process is somewhat like culturing a beer. At the end of the process, you have chicken meat," Eat Just CEO Josh Tetrick told <a href="https://www.bloomberg.com/news/videos/2021-01-11/would-you-eat-lab-grown-meat-video" rel="noopener noreferrer" target="_blank">Bloomberg</a>.</p><p>BlueNalu's President and CEO Lou Cooperhouse agreed, telling EcoWatch, "We aren't making a living being, it's just a fish fillet. It's live tissue until we freeze it. Then it's no longer live; it's the product you might have and consume every day."</p>
<h3>The Taste</h3><p>But how does it really taste? Identical to what consumers are used to, both companies told EcoWatch.</p><p>Cooperhouse described how his company mimics the "mouth feel" of conventional fish by recreating the same proportions of muscle, fat and connective tissue in their cell-based fillets. The company uses starter cells to grow all three types of tissue and then combines them to create the same exact product that consumers are used to eating.</p><p>"We're creating identical mahi-mahi to conventional mahi-mahi, from a sensory perspective and a functional perspective," Cooperhouse told EcoWatch. "When you cook it, it smells like fish. You can fry it, bake it, saute it. It caramelizes. It has all the same characteristics as fish, because it is fish. We just made it out of the body. We made it in steel tanks."</p><p>Andrew Noyes, head of global communications for Eat Just, similarly said that their chicken product "cooks, looks and tastes like chicken," including the flavor profile and texture, "because it is chicken."</p>
<h3>The Many Advantages of Cultured Foods</h3><p>Both companies emphasized how cell-based foods don't require killing animals or adding growth hormones or antibiotics. Cell-based food also removes the environmental impact of industrial farming and commercial fishing. This "critical overlay of benefits at every level" creates a new solution for global supply chains that supports biodiversity and the planet's health, Cooperhouse said.</p><p>"We want consumers to know our fillets are different in these ways," Cooperhouse added. "They're not wild, not farmed." On a <a href="https://medium.com/eat-blue/not-wild-not-farmed-but-what-should-we-call-our-seafood-made-from-fish-cells-136fa0343b4d" rel="noopener noreferrer" target="_blank">company blog</a>, Cooperhouse said that BlueNalu's products are a third alternative way to enjoy fish that is "as delicious and nutritious as their wild-caught or farm-raised counterparts... but without the mercury, microplastics or other pollutants that might be associated with conventional seafood."</p><p>Tetrick also emphasized the safety advantage of cultured meat over conventional. "This way of making meat radically decreases the probability of zoonotic diseases through our food system," he told Bloomberg, because it avoided pathogens like E. coli and salmonella, as well as sanitization concerns.</p><p>The environmental benefits of cell-cultured meat also mean less environmental destruction. Conventional <a href="https://www.ecowatch.com/tag/meat-consumption" target="_self">meat production</a> requires massive amounts of land for grazing and food production. Just growing feed for livestock <a href="https://www.ecowatch.com/meat-consumption-2021-2649770271.html">uses 71 percent of global arable land</a> and <a href="https://www.ecowatch.com/amazon-rainforest-collapse-2649776959.html#:~:text=The%20future%20of%20the%20world's,dry%2C%20shrubby%20plain%20by%202064." target="_self">drives Amazonian deforestation</a>.</p>
<p>"Chicken is the world's most consumed (and fastest growing) meat," Noyes told EcoWatch. "Chickens also consume more feed collectively than other farmed animals. Today, more than one-third of the ice-free land on Earth and tens of millions of acres of rainforest teeming with our planet's most diverse life forms have been replaced with fields of chicken feed."</p><p>According to the <a href="http://www.fao.org/documents/card/en/c/I9540EN" rel="noopener noreferrer" target="_blank">Food and Agriculture Organization of the United Nations</a>, 60 percent of the world's fisheries are fully fished, or at maximum output capacity, and 33 percent are overfished. Additionally, in the last half-century, oceanic <a href="https://www.ecowatch.com/tag/dead-zones" target="_self">dead zones</a> have quadrupled due to fishing and the <a href="https://www.ecowatch.com/climate-change/" target="_self">climate crisis</a>, reported <a href="https://bigthink.com/technology-innovation/lab-grown-fish?rebelltitem=2#rebelltitem2" rel="noopener noreferrer" target="_blank">Big Think</a>. <a href="https://www.ecowatch.com/tag/fish-farms" target="_self">Fish farming</a>, once thought to be a solution to declining wild fish populations, <a href="https://www.ecowatch.com/industrial-agriculture-problems-boycott-2554509022.html" target="_self">brings its own issues</a>, including the loss of critical mangrove habitat and the proliferation of sea lice and other diseases from farms, which escape and kill wild fish, <a href="https://www.seafoodwatch.org/seafood-basics/sustainable-solutions/preserve-habitats#:~:text=The%20exponential%20growth%20of%20aquaculture,the%20local%20people%20and%20ecosystems." rel="noopener noreferrer" target="_blank">Seafood Watch</a> reported.</p><p>Cell-based seafood won't put pressure on these depleted stocks and fragile habitats and will also avoid bycatch, a serious threat to biodiversity when unintentionally fished creatures are injured or killed.</p><p><a href="https://www.ecowatch.com/beef-and-climate-change-2634244134.html" target="_blank">Meat production</a> is also energy-intensive and generates vast amounts of methane and other greenhouse gases. Cell-based foods are more carbon efficient and climate-friendly than conventional meat and seafood because of production efficiency and a localized distribution plan.</p><p>"If you look at climate change, this way of making meat is 90 percent more carbon-efficient than the typical approach," Tetrick told Bloomberg.</p><p>BlueNalu is preparing to scale for global cities to house 150,000-square-foot facilities, each capable of producing enough cell-based seafood to feed more than 10 million local residents, NPR reported. This way, cell-based seafood will avoid greenhouse gas emissions caused by shipping.</p>
<p>Finally, waste is reduced because these companies are only growing the animal parts to be consumed. Traditionally, cattle are inefficient, requiring five to 20 pounds of plant-based feed to create one pound of conventional beef, <a href="https://www.cnet.com/news/beyond-the-impossible-meat-grown-from-cells-better-for-planet-if-you-will-eat-it/" rel="noopener noreferrer" target="_blank">CNet</a> reported. <a href="https://www.scientificamerican.com/article/lab-grown-meat/" target="_blank">Scientific American</a> estimated that one tissue sample from a cow could yield enough muscle tissue to make 80,000 quarter-pounders.<br></p><p>Cooperhouse estimated that a typical fish would produce a 60 percent yield after cutting off the head and tail and removing the skin and bones, whereas his fillets yield 100 percent.</p><p>"It's a total paradigm shift from an environmental and sustainability perspective," he told EcoWatch. "All that freight, oil, labor, dry ice, foam coolers — all goes away."</p><p>The consistency of quality, readily available products has also garnered interest from foodservice operators, Cooperhouse said. Having a stable supply available year-round will help restaurants combat the variability they currently experience.</p>
<h3>Challenges</h3><p>The big question is whether or not the general public will eat the products, once available.</p><p>"If there's an ick factor to cell-based fish, remember that most processed foods are already created in laboratories," argued Big Think. "There are no Oreo trees or ketchup plants to harvest."</p><p>A University of Queensland survey found that a majority of respondents would try the products, but less would eat them regularly or see them as conventional meat replacements, <a href="https://newatlas.com/lab-grown-meat-public-attitudes/48921/?itm_source=newatlas&itm_medium=article-body" rel="noopener noreferrer" target="_blank">New Atlas</a> reported. Respondents reported that taste would be a driving factor in favor of cell-based foods.</p><p>Cost is the other issue. For Eat Just, their products are competitively priced with premium chicken, although they foresee a pathway for a cheaper price within the next five years, Tetrick told Bloomberg. BlueNalu doesn't yet have a price point for their inaugural mahi-mahi fillet, but are aggressively partnering with known brands and distributors to lower costs.</p><h3>What's Next</h3><p>Singapore's approval of Eat Just's nugget is paving the way for other companies and nations to follow suit, <a href="https://www.theguardian.com/environment/2020/dec/02/no-kill-lab-grown-meat-to-go-on-sale-for-first-time" target="_blank">The Guardian reported</a>. Both Eat Just and BlueNalu are actively engaging regulators in the U.S. and other countries to bring their products online as quickly and safely as possible. Since the products are not genetically modified, "the approval will be about whether this is safe, clean, and are the manufacturing processes reliable and accountable," Cooperhouse told NPR.</p><p>While not a substitute for all conventional food, if cell-based meats and seafood are scaled up and accepted, <a href="https://www.ecowatch.com/meat-consumption-predictions-vegan-lab-2638801931.html" target="_self">many hope to feed the world's anticipated 9.5 billion people</a> without stripping the planet bare and ruining the climate.</p><p>"The simplest way to think about it is it allows all of us to consume meat, the good part, the nutritional composition, the taste, and do away with the bad part, which is the killing, the environmental deforestation, the acceleration of zoonotic disease, and we can still have a fried chicken," Tetrick told Bloomberg.</p>

New Zealand sea lions are an endangered species and one of the rarest species of sea lions in the world. Art Wolfe / Photodisc / Getty Images
One city in New Zealand knows what its priorities are.
Dunedin, the second largest city on New Zealand's South Island, has closed a popular road to protect a mother sea lion and her pup, The Guardian reported.
<p>"We've closed John Wilson Ocean Drive to vehicles for the next month to allow some special residents to use the road safely - a New Zealand sea lion and her pup have taken up residence at the golf course next door and are regularly crossing the road to get to the beach," the Dunedin City Council wrote in a <a href="https://www.facebook.com/DunedinCityCouncil/posts/3687384977973820" rel="noopener noreferrer" target="_blank">Facebook Post Monday</a>.</p>
<div class="rm-shortcode" data-rm-shortcode-id="30b8c8ee5783728b66f03a8cd2d1ab14"><div class="fb-post" data-href="https://www.facebook.com/DunedinCityCouncil/photos/a.226655984046754/3687384087973909/"></div></div>
<p>The council said that residents could still walk or ride bikes in the area, but should stay at least 20 meters (approximately 66 feet) away from the sea lions at all times and keep any dogs on a leash.</p><p>The mother sea lion, named Hiriwa, was first spotted on the Chisholm Links golf course about a week ago and is now nesting with her pup in a bush near the 13th hole, <a href="https://www.rnz.co.nz/news/national/434504/sea-lion-makes-itself-at-home-on-dunedin-golf-course" target="_blank">Radio New Zealand reported</a>.</p>

<p>This is her fifth pup, Department of Conservation (DOC) coastal Otago <a href="https://www.ecowatch.com/tag/biodiversity" target="_self">biodiversity</a> ranger Jim Fyfe said.<br></p><p>"She has come up John Wilson Drive and into the golf course to have her pup in some bushes there," he told Radio New Zealand.</p><p>Fyfe also told the <a href="https://www.nzherald.co.nz/nz/dunedin-road-temporarily-closed-for-sea-lion-and-pup/XMOZAJTUISN7OCIRS6H7OSGPHY/" rel="noopener noreferrer" target="_blank">New Zealand Herald</a> that the pup was born Thursday, Jan. 7 and immediately made its presence known by making lots of noise.</p><p>The mother and pup will now spend about a month nesting before heading out to sea, Fyfe explained. During that time, the mother will need to walk 500 meters (approximately 1,640 feet) to the beach each day to feed. On these journeys, she will think to avoid male sea lions, but she won't be thinking about cars, people or dogs. That is why the road closure is so important, Fyfe explained.</p>
<p>Local residents have responded favorably to the council's decision, The Guardian reported.</p><p>"Awesome! Love our little country in this way," one commenter wrote on Facebook.</p><p>The golf course has also welcomed its new residents.</p><p>"We're lucky to have marine mammals on our coastline and we need to share the space with them, as this is what makes our coastal Links and Dunedin's coastline so unique!" it wrote in a <a href="https://www.facebook.com/ChisholmLinks/posts/3417932631666520" target="_blank">Jan. 5 Facebook post</a>.</p>

<p>New Zealand sea lions are an <a href="https://www.ecowatch.com/tag/endangered-species" target="_self">endangered species</a> and one of the rarest species of sea lions in the world, the city council noted. There are around 12,000 left in the world, according to DOC figures reported by <a href="https://www.cnn.com/travel/article/new-zealand-sea-lions-road-closure-scli-intl/index.html" target="_blank">CNN</a>. Killing one can bring a penalty of up to two years in prison or a fine of up to $178,000.</p><p>Dunedin's 120,000 residents are used to road closures to protect <a href="https://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a>, but usually these closures last for a day rather than a month, The Guardian explained. The city is also used to welcoming breeding sea lions since 1993, and their numbers in the city have increased since <a href="https://www.ecowatch.com/tag/conservation" target="_self">conservation</a> efforts intensified.</p><p>Despite this, the overall breeding population of New Zealand sea lions is still falling. The main threats to the species are fishing, disease, human activity and lack of food.</p><p>Still, this is shaping up to be a good year for sea lions in Dunedin.</p><p>"This year we expect 20 sea lions around Dunedin to give birth. This is going to be a record number for us," Fyfe told Radio New Zealand. "New Zealand sea lions are a threatened species that is just recovering on the mainland coastline, so it's really good news."</p>

In an alarming new study, scientists found that climate change is already harming children's diets.
<p>It has long been understood that climate change will impact diet and food security globally. But up until now, little research proved how diet diversity is impacted by climate change outcomes, like warmer temperatures and increased precipitation, over a span of geographical areas.</p><p>Led by researchers at the University of Vermont, the study surveyed the diets of more than 107,00 children under the age of five, across 19 countries in Asia, Africa, and South America, with 30 years of precipitation and temperature data, according to the <a href="https://iopscience.iop.org/article/10.1088/1748-9326/abd0ab" target="_blank">study</a>.</p>
<p>Higher, long-term temperatures were associated with decreased diet diversity among children. "It surprised us that higher temperatures are already showing an impact," Meredith Niles, the study's lead author and an assistant professor of Nutrition and Food Sciences at the University of Vermont, said in an <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank">article</a>.</p><p>In 2019, over 144 million children under the age of five were malnourished, <a href="https://data.unicef.org/topic/nutrition/malnutrition/#:~:text=In%202019%2C%2021.3%20per%20cent,5%20worldwide%20had%20stunted%20growth.&text=Between%202000%20and%202019%2C%20stunting,199.5%20million%20to%20144.0%20million." target="_blank">according to data by the UNICEF</a>. This number could have grown by an additional 6.7 million in 2020 alone, exacerbated by the COVID-19 pandemic, according to a <a href="https://www.unicef.org/press-releases/unicef-additional-67-million-children-under-5-could-suffer-wasting-year-due-covid-19" target="_blank" rel="noopener noreferrer">report published in July</a>.</p>
<p>In the study, researchers used a scale developed by the United Nations to understand intakes of micronutrients like iron, folic acid, zinc and vitamins A and D.</p><p>On average children ate 3.2 out of 10 food groups. But in "emerging economies" like in China, children ate 6.8 out of 10 food groups, more than doubling the overall average, according to the <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank" rel="noopener noreferrer">University of Vermont</a>. Household wealth, consequently, was the biggest factor in children's diet diversity, <a href="https://www.reuters.com/article/global-climate-food/scientists-warn-climate-change-is-harming-childrens-diets-idUSL8N2JO4P4" target="_blank" rel="noopener noreferrer">Reuters reported</a>.</p><p>"These results suggest that, if we don't adapt, climate change could further erode a diet that already isn't meeting adequate child micronutrient levels," Brendan Fisher from UVM's Rubenstein School of Environment and Natural Resources <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank">said</a> about children's diets in developing countries.</p>
<p>Although the study proved what researchers had long expected regarding warming temperatures, they did find surprising results on how precipitation alters diet diversity.</p><p>Higher precipitation, linked to countries in West and Southeast Africa and Central America, was associated with higher diversity in children's diet, the University of Vermont <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank">reported</a>.</p><p>"Higher rainfall in the future may provide important diet quality benefits in multiple ways, but it also depends on how that rain comes," Molly Brown, a co-author of the study <a href="https://www.uvm.edu/gund/news/climate-change-hurting-childrens-diets-global-study-finds-0" target="_blank" rel="noopener noreferrer">said</a>. "If it's more erratic and intense, as is predicted with climate change, this may not hold true."</p><p>Changes in the agriculture and the food industry can also be linked to worsening diets, Paolo Vineis of Imperial College London, who studies the effects of climate change on the disease, <a href="https://www.reuters.com/article/global-climate-food/scientists-warn-climate-change-is-harming-childrens-diets-idUSL8N2JO4P4" target="_blank" rel="noopener noreferrer">told Reuters</a>.</p><p>By 2050, global demand for food may increase by 59 to 98 percent from a larger population. Although this will require major agricultural and food industries to rapidly expand their production, droughts and higher temperatures will threaten their ability to do so, <a href="https://blogs.ei.columbia.edu/2018/07/25/climate-change-food-agriculture/" target="_blank" rel="noopener noreferrer">Columbia University's Earth Institute reported</a>.</p>
<p>In the United States alone, for example, the production of corn, which is used to feed livestock, could decrease by 50 percent if the planet warms by four degrees Celsius, <a href="https://www.pnas.org/content/115/26/6644" target="_blank" rel="noopener noreferrer">a study found</a>, a likely temperature increase predicted for 2100.</p><p>So what kind of solutions can help?</p><p>Educating investors on the financial risks and potential opportunities of the climate crisis could help the food industry adapt to the climate impacts already being felt, Columbia University's Earth Institute <a href="https://blogs.ei.columbia.edu/2018/07/25/climate-change-food-agriculture/" target="_blank" rel="noopener noreferrer">reported</a></p><p>"Food security is going to be one of the most pressing climate-related issues, mainly because most of the world is relatively poor and food is going to become increasingly scarce and expensive," Peter De Menocal, founding director of Columbia's Center for Climate and Life, <a href="https://blogs.ei.columbia.edu/2018/07/25/climate-change-food-agriculture/" target="_blank" rel="noopener noreferrer">told Columbia's Earth Institute</a>.</p><p>As for improving diets globally, researchers at the University of Vermont <a href="https://iopscience.iop.org/article/10.1088/1748-9326/abd0ab" target="_blank" rel="noopener noreferrer">stress</a> the need for more research aimed at protecting children's nutrition especially for "vulnerable populations in low and middle-income countries across the tropics where the most profound climate changes are expected."</p>
