COVID-19 has disrupted our daily lives, and it is poised to completely disrupt the holiday season. As people make holiday plans and think about ways to reduce the risks to their loved ones, a strategy is essential.
Are masks really necessary at family gatherings?<p>If you're gathering with friends and family who don't live in your home, yes. Just because you're with people you know doesn't mean you're safe from the coronavirus. Infection rates are <a href="https://coronavirus.jhu.edu/data/new-cases-50-states" target="_blank" rel="noopener noreferrer">higher now than they have ever been</a> in the U.S., and <a href="https://youtu.be/ehdgceGzQxs" target="_blank" rel="noopener noreferrer">small gatherings have been a source</a> of viral spread. All it takes is one infected person who doesn't know they have the coronavirus to infect others.</p><p>Remember, people can be <a href="https://medical.mit.edu/covid-19-updates/2020/07/how-long-symptom-onset-person-contagious" target="_blank" rel="noopener noreferrer">contagious two to three days</a> before symptoms show – that's one thing that makes this virus so hard to stop. And it's why, even if you feel fine, you should wear a mask.</p><p>The Centers for Disease Control and Prevention now estimates that when both people are wearing masks, the <a href="https://www.cdc.gov/coronavirus/2019-ncov/more/masking-science-sars-cov2.html" target="_blank">likelihood of infection is low</a>.</p>
Who am I protecting when I wear a mask?<p>In a word: everyone. The coronavirus <a href="https://theconversation.com/aerosols-are-a-bigger-coronavirus-threat-than-who-guidelines-suggest-heres-what-you-need-to-know-142233" target="_blank">spreads through respiratory droplets</a> that you send out into the air when you talk, sing or even just breathe. The tiniest of these droplets can float on air currents for long periods.</p><p>Face masks stop many of those droplets, reducing the amount of virus in the air. That lowers your chances of getting infected, and it also lowers the chances that you'll infect someone else.</p><p><a href="https://www.cdc.gov/coronavirus/2019-ncov/more/masking-science-sars-cov2.html" target="_blank">Studies of people who had prolonged exposure</a> to others with COVID-19 have demonstrated how masks can reduce the chance of the virus spreading. In general, <a href="https://www.cdc.gov/coronavirus/2019-ncov/more/masking-science-sars-cov2.html" target="_blank" rel="noopener noreferrer">well-fitted cloth masks</a> made up of multiple layers can stop most large droplets and at least half of the tiny ones. Plastic <a href="https://doi.org/10.1101/2020.10.05.20207241" target="_blank" rel="noopener noreferrer">face shields</a> alone are far less effective. <a href="https://www.washingtonpost.com/health/2020/08/13/cdc-mask-guidance-masks-valves/" target="_blank" rel="noopener noreferrer">Face masks with valves or vents</a> might be good for construction work, but they don't stop the wearer from breathing out virus into the air.</p>
Can I reuse a mask and when should I replace it?<p>Reusable masks should be kept clean and dry. We're moving into cold and flu season, and noses get drippy. A rule of thumb: Anytime a mask is wet to the point that you can discern the wetness, it's time for a new one if it's disposable, or it's time to clean your reusable mask.</p><p>Wetness allows viruses to more easily move through paper or fabric because it allows the threads to move and may reduce the electrostatic charge in the masks that add extra protection with some fabrics.</p><p>In general, you can use a mask that stays clean and dry for about a week before you need to wash or discard it.</p>
How should I clean a cloth mask?<p>Washing your mask is like washing your clothes. You know when it is time.</p><p>In general, <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/how-to-wash-cloth-face-coverings.html" target="_blank">cleaning your mask weekly</a> should be sufficient. If odors develop before then, it's a good idea to wash it sooner. Odor generally means bacterial buildup.</p><p>Cleaning your mask by hand with soap and water is your best option. Using a general detergent on a gentle cycle in the washing machine is also fine, but that may increase the risk of damage, depending on the quality of the material. COVID-19 is not a hardy virus. Any soap or detergent should work fine. There's no need for special chemicals, bleach or harsh soaps.</p><p>Be careful to remove any inserts before washing. Inserted filters are generally not washable.</p><p>Air drying masks works best. Remember, masks should be completely dry before use. So be sure to have a replacement mask handy while the one you just washed dries.</p><p>Sunlight is always a great source of heat to dry your mask. Also, sunlight has ultraviolet radiation, which has been shown to <a href="http://doi.org/10.1111/php.13293" target="_blank" rel="noopener noreferrer">eliminate coronavirus</a> and is also known to have antibacterial properties.</p>
Can I wear the mask below my nose?<p>Wearing your mask below your nose is, frankly, ridiculous.</p><p>Think about it. If you are breathing through your nose and only covering your mouth, you are effectively eliminating the point of the mask. Properly wearing a mask requires covering both your nose and mouth at all times.</p><p>Studies show that wearing a proper cloth mask or surgical mask while exercising <a href="http://doi.org/10.1513/AnnalsATS.202008-990CME" target="_blank">doesn't affect the flow of oxygen</a> or carbon dioxide in any detectable way. So, unless you have serious heart and lung problems, that isn't an excuse.</p>
How do I safely remove my mask if I’m going to eat or drink?<p>When you <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/how-to-wash-cloth-face-coverings.html" target="_blank">take your mask off</a>, remove it carefully by the straps without touching anything else and put it somewhere safe, like wrapped in paper in a purse, bag or pocket. Then wash your hands or use hand sanitizer. When you put it back on, wash your hands again.</p>
So, how can I have a safe holiday gathering?<p>The safest way to celebrate this year is to do so with members only within your household. The <a href="https://www.cdc.gov/coronavirus/2019-ncov/daily-life-coping/holidays.html" target="_blank" rel="noopener noreferrer">CDC is now stressing that point</a>, as well. If you do celebrate with friends and relatives from outside your household, you need an action plan to reduce the risk of exposure.</p><p>Here are five recommendations:</p><ul><li>Limit the number of people – fewer people means fewer opportunities for exposure, and you'll have more room to spread out.</li><li>Require masks when not eating or drinking.</li><li>Use physical distancing when eating. Try to seat people <a href="https://doi.org/10.1136/bmj.m3223" target="_blank" rel="noopener noreferrer">at least 6 feet apart</a>. Eat outside if you can.</li><li>Consider being tested for COVID-19 before traveling or gathering. It's not a guarantee, but it can help flag illnesses. Remember to self-isolate between the test and the event.</li><li>Be prepared to self-isolate for 14 days after traveling or participating in any event that involves people from outside your home.</li></ul><p>[<em>Research into coronavirus and other news from science</em> <a href="https://theconversation.com/us/newsletters/science-editors-picks-71/?utm_source=TCUS&utm_medium=inline-link&utm_campaign=newsletter-text&utm_content=science-corona-research" target="_blank" rel="noopener noreferrer">Subscribe to The Conversation's new science newsletter</a>.]</p><p><em>The map has been updated with New Hampshire announcing a mask mandate effective Nov. 20.</em></p><p><em>Jason Farley is a professor, infectious disease-trained epidemiologist and nurse practitioner at the Johns Hopkins University School of Nursing.<br></em></p><p><em>Disclosure statement: Jason Farley, PhD, MPH, ANP-BC, FAAN receives funding from the National Institutes of Health on the Rapid Acceleration of Diagnostics for COVID-19 and Becton Dickinson for studies on SARS-CoV-2 diagnostics.</em></p><p><em>Reposted with permission from <a href="https://theconversation.com/why-face-masks-belong-at-your-thanksgiving-gathering-7-things-you-need-to-know-about-wearing-them-150130" target="_blank">The Conversation</a>. </em></p>

Masks slow the spread of SARS-CoV-2 by reducing how much infected people spray the virus into the environment around them when they cough or talk. Evidence from laboratory experiments, hospitals and whole countries show that masks work, and the Centers for Disease Control and Prevention recommends face coverings for the U.S. public. With all this evidence, mask wearing has become the norm in many places.
Exposure Dose Determines Severity of Disease<p>When you breathe in a respiratory virus, it immediately begins hijacking any cells it lands near to <a href="https://doi.org/10.1016/j.cell.2020.05.042" target="_blank">turn them into virus production machines</a>. The immune system tries to stop this process to halt the spread of the virus.</p><p>The amount of virus that you're exposed to – called the viral inoculum, or dose – <a href="https://doi.org/10.1038/nri2802" target="_blank">has a lot to do with how sick you get</a>. If the exposure dose is very high, the immune response can become overwhelmed. Between the virus taking over huge numbers of cells and the immune system's drastic efforts to contain the infection, a lot of damage is done to the body and a person can become very sick.</p><p>On the other hand, if the initial dose of the virus is small, the immune system is able to contain the virus with less drastic measures. If this happens, the person experiences fewer symptoms, if any.</p><p>This concept of viral dose being related to disease severity has been around for <a href="https://doi.org/10.1093/oxfordjournals.aje.a118408" target="_blank">almost a century</a>. Many animal studies have shown that the higher the dose of a virus you give an animal, the <a href="https://doi.org/10.1258%2Fla.2012.011157" target="_blank">more sick it becomes</a>. In 2015, researchers tested this concept in human volunteers using a nonlethal flu virus and found the same result. The higher the flu virus dose given to the volunteers, <a href="https://doi.org/10.1093/cid/ciu924" target="_blank">the sicker they became</a>.</p><p>In July, researchers published a paper showing that viral dose was related to disease severity in hamsters exposed to the coronavirus. Hamsters who were given a higher viral dose <a href="https://doi.org/10.1073/pnas.2009799117" target="_blank">got more sick than hamsters given a lower dose</a>.</p><p>Based on this body of research, it seems very likely that if you are exposed to SARS-CoV-2, the lower the dose, the less sick you will get.</p><p>So what can a person do to lower the exposure dose?</p>
Masks Reduce Viral Dose<p>Most infectious disease researchers and epidemiologists believe that the coronavirus is <a href="https://doi.org/doi:10.1001/jama.2020.12458" target="_blank">mostly spread by airborne droplets</a> and, to a lesser extent, tiny aerosols. Research shows that both cloth and surgical masks can <a href="https://dx.doi.org/10.7326%2FM20-2567" target="_blank">block the majority of particles that could contain SARS-CoV-2</a>. While no mask is perfect, the goal is not to block all of the virus, but simply reduce the amount that you might inhale. Almost any mask will successfully block some amount.</p><p>Laboratory experiments have shown that good cloth masks and surgical masks could block at least <a href="https://doi.org/10.1093/annhyg/meq044" target="_blank">80% of viral particles from entering your nose and mouth</a>. Those particles and other contaminants will get trapped in the fibers of the mask, so the CDC recommends <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/how-to-wash-cloth-face-coverings.html" target="_blank">washing your cloth mask after each use if possible</a>.</p><p>The final piece of experimental evidence showing that masks reduce viral dose comes from another hamster experiment. Hamsters were divided into an unmasked group and a masked group by placing surgical mask material over the pipes that brought air into the cages of the masked group. Hamsters infected with the coronavirus were placed in cages next to the masked and unmasked hamsters, and air was pumped from the infected cages into the cages with uninfected hamsters.</p><p>As expected, the masked hamsters were less likely to get infected with COVID-19. But when some of the masked hamsters did get infected, <a href="https://doi.org/10.1093/cid/ciaa644" target="_blank">they had more mild disease</a> than the unmasked hamsters.</p>
Masks Increase Rate of Asymptomatic Cases<p> In July, the CDC estimated that around <a href="https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scenarios.html" target="_blank">40% of people infected with SARS-CoV-2 are asymptomatic</a>, and a <a href="https://doi.org/10.7326/M20-3012" target="_blank">number of other studies</a> have <a href="https://theconversation.com/can-people-spread-the-coronavirus-if-they-dont-have-symptoms-5-questions-answered-about-asymptomatic-covid-19-140531" target="_blank">confirmed this number</a>. </p><p> However, in places where everyone wears masks, the rate of asymptomatic infection seems to be much higher. In an <a href="https://www.msn.com/en-us/travel/news/greg-mortimer-passengers-to-be-evacuated-after-almost-60-test-positive-for-coronaviru/ar-BB12ie3v" target="_blank">outbreak on an Australian cruise ship</a> called the Greg Mortimer in late March, the passengers were all given surgical masks and the staff were given N95 masks after the first case of COVID-19 was identified. Mask usage was apparently very high, and even though 128 of the 217 passengers and staff eventually tested positive for the coronavirus, <a href="https://doi.org/10.1136/thoraxjnl-2020-215091" target="_blank">81% of the infected people remained asymptomatic</a>. </p><p> Further evidence has come from two more recent outbreaks, the first at a <a href="https://apnews.com/4b9d38f206db9ce5267a5898ac24f238" target="_blank">seafood processing plant in Oregon</a> and the second at a <a href="https://www.tysonfoods.com/news/news-releases/2020/6/tyson-foods-inc-releases-covid-19-test-results-northwest-arkansas" target="_blank">chicken processing plant in Arkansas</a>. In both places, the workers were provided masks and required to wear them at all times. In the outbreaks from both plants, nearly <a href="https://doi.org/10.1007/s11606-020-06067-8" target="_blank">95% of infected people were asymptomatic</a>. </p><p> There is no doubt that universal mask wearing slows the spread of the coronavirus. My colleagues and I believe that evidence from laboratory experiments, case studies like the cruise ship and food processing plant outbreaks and long-known biological principles make a strong case that masks protect the wearer too. </p><p> The goal of any tool to fight this pandemic is to slow the spread of the virus and save lives. Universal masking will do both. </p><p> <a href="https://theconversation.com/profiles/monica-gandhi-1080710" target="_blank">Monica Gandh</a> is a Professor of Medicine, Division of HIV, Infectious Diseases and Global Medicine at the University of California, San Francisco. </p><p> Disclosure statement: Monica Gandhi does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. </p><p> <em>Reposted with permission from <a href="https://theconversation.com/cloth-masks-do-protect-the-wearer-breathing-in-less-coronavirus-means-you-get-less-sick-143726" target="_blank">The Conversation</a>.</em><em></em> </p>
Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.

The COVID-19 pandemic has disrupted the U.S. recycling industry. Waste sources, quantities and destinations are all in flux, and shutdowns have devastated an industry that was already struggling.

Recyclers Under Pressure<p>Since March 2020, when most shelter-in-place orders began, sanitation workers have noted massive increases in municipal garbage and recyclables. For example, in cities like Chicago, workers have seen up to <a href="https://chicago.suntimes.com/coronavirus/2020/4/7/21212543/coronavirus-chicago-garbage-pickup-streets-sanitation-masks" target="_blank">50% more waste</a>.</p><p>According to the <a href="https://swana.org/" target="_blank">Solid Waste Association of North America</a>, U.S. cities saw a <a href="https://swana.org/news/swana-news/article/2020/06/17/swana-submits-statement-on-recycling-challenges-for-u.s.-senate-hearing" target="_blank">20% average increase</a> in municipal solid waste and recycling collection from March into April 2020. Increased trash can be attributed partly to spring cleaning, but most of it is due to people spending greater time at home. Restaurants struggling to survive under COVID-19 restrictions are contributing to the rise in plastic and paper waste with <a href="https://theconversation.com/using-lots-of-plastic-packaging-during-the-coronavirus-crisis-youre-not-alone-135553" target="_blank">takeout packaging</a>.</p><p>Although higher volumes of recyclables are being set on the curb, budget deficits are squeezing recycling programs. Many municipalities are struggling with <a href="https://www.ketv.com/article/omaha-mayor-health-officials-to-provide-covid-19-update-friday-afternoon/32498068#" target="_blank">multimillion-dollar shortfalls</a>. Some communities, such as Rock Springs, Wyoming, and East Peoria, Illinois, <a href="https://resource-recycling.com/recycling/2020/05/27/budget-shortfalls-threaten-local-recycling-programs/" target="_blank">have cut recycling programs</a>.</p><p>And these stresses are testing a business already faced uncertainty.</p>
While bottle deposit stations remain closed, recyclables pile up in basements and garages. David Rieland / CC BY-ND
Turmoil in Scrap Markets<p>The global recycling economy has suffered since 2018 as first China and then other Asian nations <a href="https://theconversation.com/as-more-developing-countries-reject-plastic-waste-exports-wealthy-nations-seek-solutions-at-home-117163" target="_blank">banned imports of low-quality scrap</a> — often meaning improperly cleaned food packaging and poorly sorted recyclable materials. As in any business, the value of raw recyclables is linked to supply and demand. Without demand from nations like China, which formerly took up to 700,000 tons of U.S. scrap annually, recyclers have scrambled to stay in business.</p><p>The pandemic has boosted prices for some materials. One industry leader told us that between February and May 2020, prices doubled for recycled paper and tripled for recycled cardboard. These shifts reflect higher demand for tissue products and shipping packaging under shelter-in-place orders.</p><p>However, he also reported that prices for the most-recycled categories of reclaimed plastics — PET (#1) and PE (#2 and #4) – were at 10-year lows. An influx of cheap oil has driven the raw material cost of oil-derived virgin plastics to their lowest levels in decades, <a href="https://millerrecycling.com/oil-prices-recycling#:%7E:text=Higher%20oil%20prices%20can%20also,robust%20market%20for%20recycled%20plastic." target="_blank">outcompeting recycled feedstocks</a>.</p>
Difficult Economics<p>Ideally, revenues from recycling offset municipalities' costs for collecting and disposing of solid wastes. However, given worker safety concerns, low market prices for scrap materials, a slowed economy and cheaper alternatives for disposal, many communities and businesses across the U.S. have <a href="https://www.wastedive.com/news/recycling-mrfs-prison-labor-suspensions-coronavirus-covid-19/574301/" target="_blank">temporarily suspended</a> collection of recyclables and bottle deposits.</p><p>Meanwhile, as the commercial sector slowed, the distribution of waste generation changed. As people have spent more time producing waste at home, waste collectors implemented <a href="https://www.wastedive.com/news/coronavirus-covid-waste-recycling-safety-collection-mrf/574359/" target="_blank">new procedures</a> to protect their employees from infection.</p><p>Recycling is a very hands-on process that requires workers to manually sort out items from the collection stream that are unsuitable for mechanical processing. Workers and waste collection companies have <a href="https://www.wastedive.com/news/coronavirus-covid-waste-recycling-safety-collection-mrf/574359/" target="_blank">raised many safety questions</a> about recycling during the pandemic.</p><p>Precautions like social distancing and use of personal protective equipment have become commonplace among waste collectors and sorters, though concerns remain. Sorters are increasingly relying on automation, but implementation can be costly and takes time.</p>
Collections on Pause<p>Based on monitoring since 2017 by the trade publication <a href="https://www.wastedive.com/news/curbside-recycling-cancellation-tracker/569250/" target="_blank">Waste Dive</a>, nearly 90 curbside recycling programs had experienced or continue to experience a prolonged suspension over the past several years. About 30 of these suspensions have occurred since January 2020.</p>
Like many bottle deposit programs, Kroger's Ann Arbor, Mich. drop-off center shut down on March 23. Michigan bottle deposits across the state resumed on June 15, 2020 with new safety protocols. Brian Love / CC BY-ND<p>On a broader scale, it's not clear how much more waste Americans are currently producing during shutdowns. Commercial and residential waste aren't directly comparable. For example, a granola bar wrapper thrown away at the office is tallied differently than if discarded at home.</p><p>It is also challenging to quantify the effects of the pandemic while it is still unfolding. Historically, waste output from the commercial and industrial sectors has far outweighed the municipal stream. With many offices and business closed or operating at low levels, total U.S. waste production could actually be at a record low during this time. However, data on commercial and industrial wastes are not readily available.</p><p>At the California-based <a href="https://resource-recycling.com/recycling/2020/04/28/city-data-shows-covid-19-impacts-on-recycling-tonnages/" target="_blank">Peninsula Sanitary Service</a>, which serves the Stanford University community, total tonnage was down 60% in March. The company attributes this drop to reduced commercial waste, particularly from construction. Similarly, the city of Vancouver, British Columbia, noted a <a href="https://www.cbc.ca/news/canada/british-columbia/metro-vancouver-garbage-decrease-covdi-19-1.5544942" target="_blank">10% decrease</a> year over year of waste collection levels for April.</p>
Expected sectors of plastic waste increase due to COVID-19, based on 2018 plastic usage distribution data from PlasticsEurope and Klemes et al., 2020. Brian Love and Julie Rieland / CC BY-ND
More Plastic Trash<p>As cities and industries reopen in the coming months, new data will show the pandemic's effects on consumer habits and waste generation. But regardless of total volume, the mix of materials in household wastes has shifted given the new ubiquity of single-use plastic containers, online shopping packaging and disposable gloves, wipes and face masks. Many of these new staples of pandemic life are made from plastics that are simply not worth recycling if there are any other disposal options.</p><p>Today Americans are trying to balance their physical well-being against ever-mounting piles of plastic waste. At a time when reducing and reusing could be dangerous, and recycling economics are unfavorable, we see a need for better options, such as more <a href="https://theconversation.com/bio-based-plastics-can-reduce-waste-but-only-if-we-invest-in-both-making-and-getting-rid-of-them-98282" target="_blank">compostable packaging</a> that is both safer and more sustainable.</p>

With the advent of an infectious disease outbreak, epidemiologists and public health officials quickly try to forecast deaths and infections using complex computer models. But with a brand new virus like the one that causes COVID-19, these estimates are complicated by a dearth of credible information on symptoms, contagion and those who are most at risk.
This simple actuarial model uses general guidelines, rather than data and assumptions about COVID-19 specifically, to simulate the effect of safety protocols. Here, a hypothetical group of 100 infected people out of a population of 1,000, with 10% observing good safety protocols, leads to hundreds of infections and deaths after three months. Goldenson Center at the University of Connecticut, Author provided
This simulation shows the effect on the same hypothetical group of 100 infected people out of a group of 1,000 where 80% of people wear masks and practice social distancing, which slows the infection rate to almost zero after two months. Goldenson Center for Actuarial Research, CC BY-NC-ND
Why it Matters<p>By inputting different assumptions, people can see how their community's personal actions can change the course of this pandemic — and how poor protocols can trigger <a href="https://theconversation.com/coronavirus-cases-are-growing-exponentially-heres-what-that-means-135181" target="_blank">exponential spread</a> of the virus.</p><p>For example, let's assume that 100 people are infected out of a population of 1,000, with one in 10 wearing masks, keeping appropriate distance and quarantining if necessary. The model shows that 30 days later, the virus would have killed 156 people. After three months, the death toll reaches 460 — with 510 now infected.</p><p>However, our model shows that if half the population practices safe protocols, infections after 90 days drop to 293 and deaths drop even more dramatically, to 149 — about one-third of the lives lost under looser measures.</p><p>The main takeaway is that safety measures that are within our control have significant impact — and ignoring those protocols can have dire consequences.</p><p>If a state opens up and maintains safety measures for at least three months, the virus will be contained and possibly eliminated. On the other hand, if a state opens up too soon and its residents ignore safety protocols, there could be an exponential increase in COVID-19 deaths within months. It's important for the public to realize that spread of the virus is impacted only by personal behavior.</p>
What’s Next?<p>Our model shows that there must be continued emphasis on maintaining necessary safety measures as we relax shelter-in-place rules and get people back to work. Practicing common-sense social distancing, wearing masks in public and quarantining when necessary is a small inconvenience for a limited amount of time — that will contain the devastation of this virus and ensure that our economy is restored.</p>

It started with Eve donning a black mask against a backdrop of wisteria flowers, hashtagging her efforts #MaskingForAFriend. Sophia Bush, Matt McGorry, and Mayim Bialik soon followed, with others quickly joining the cause launched by the Pandemic Action Network.
How Do Masks Protect People From COVID-19?<p>There's been a lot of confusion surrounding the benefits of using masks in the battle against COVID-19, and even the U.S. government has sent <a href="https://www.post-gazette.com/opinion/editorials/2020/04/22/Mask-confusion-Health-officials-give-conflicting-messages/stories/202004170049" target="_blank">conflicting messages</a>.</p><p>But now, thanks to evolving science and a better understanding of exactly whom masks protect, most health officials seem to finally be on the same page.</p><p>"<a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/cloth-face-cover.html" target="_blank">CDC</a> recommends that people wear a cloth face covering to cover their nose and mouth in the community setting," said <a href="https://www.cdc.gov/media/spokesperson/bell/index.html" target="_blank">Dr. Mike Bell</a>, deputy director of the Centers for Disease Control and Prevention (CDC) Division of Healthcare Quality Promotion. "This is to protect people around you if you are infected but do not have symptoms by blocking your respiratory droplets."</p><p>Bell has been working to provide the necessary medical perspective for the #MaskingForAFriend campaign, explaining that masking for others is what scientists and medical experts refer to as source control.</p><p>"If everyone does this, the amount of infection being spread in our communities can be greatly reduced," he said.</p>
What Else Might Masks Protect Against?<p><a href="https://providerdirectory.uabmedicine.org/provider/Kierstin+Kennedy/574872" target="_blank">Dr. Kierstin Kennedy</a>, chief of hospital medicine at the University of Alabama at Birmingham, said, "Masks can protect against any infectious illness that may be spread by droplets. For example, the flu, pertussis (whooping cough), or pneumonia."</p><p>Bell agrees, adding that wearing a cloth mask has benefits beyond slowing the spread of COVID-19, and that source control can reduce the transmission of many other easily spread respiratory infections — the kind that typically render people infectious even before they display symptoms, like influenza.</p><p>"Some international reports have noted a lower impact of flu related to the uptake of measures to prevent COVID-19," Bell said.</p><p>But that doesn't necessarily mean masks are for everyone.</p><p>"Cloth face coverings should not be placed on young children younger than 2 years of age, anyone who has trouble breathing, or anyone who is unconscious, incapacitated, or otherwise unable to remove the cover without assistance," Bell explained.</p>
Could Face Masks Become an Ongoing Trend?<p>The experts we spoke with agree that until the threat of this pandemic has been neutralized, people should embrace the protection masks allow them to provide to those around them.</p><p>After all, it's not necessarily about you — it's about everyone you come in contact with.</p><p>It's not at all uncommon to be an asymptomatic carrier of the new coronavirus — which means that even if you have no symptoms at all, you could potentially transmit the virus to someone who could then become gravely ill or even die.</p><p>A mask, alongside frequent handwashing and physical distancing measures, like staying at least 6 feet (2 meters) apart, reduces that risk.</p><p>But could this be a trend that continues even after COVID-19? And perhaps the more important question: Should it?</p><p>"As we start to navigate life beyond the stay-at-home orders, we likely will need to continue to use face masks if we want to prevent continued transmission," Kennedy said.</p><p>But she's unsure of what the future may hold beyond that.</p><p>"Once the threat of COVID-19 is gone, I don't think that ongoing use of face masks in public has to continue, though it remains to be seen whether we will adopt ongoing face mask use just as we have seen in Asian countries," Kennedy said.</p>
Being Honest About the Drawbacks of Face Masks<p>While wearing a face mask in public is one more way we can help protect our friends, loved ones, and community, that doesn't mean doing so is without sacrifice.</p><p>"Face masks certainly impact the way that we interact socially," Kennedy said. "You lose the ability to connect with others in the nonverbal ways that are customary."</p><p>As an example, she says before COVID-19 you may have flashed a warm smile to someone you were rushing past in the street — a way to convey you weren't trying to be rude and to pass along a nonverbal hello.</p><p>"We will likely have to find a new normal as it relates to expected social interactions," she said.</p><p>Face masks also affect individuals with hearing disabilities, who often rely on lip reading to some extent to effectively communicate with others.</p><p>However, for those who are simply struggling with embarrassment over wearing a mask when others are not, she pointed out, "There is nothing awkward or embarrassing about protecting your health or the health of those around you. Find a mask that fits and wear it proudly."</p><p>Bell agrees. "The good thing about everyone wearing a cloth face cover when they're out in public is that it sends the message that we're all in this together, and there's no reason to be embarrassed about wearing one," she said.</p><p>In other words, the more people who take that step, the more united we will be.</p><p>But there's one more complaint about face masks that may present a bigger challenge: For some people, breathing behind the mask has proven to be difficult. And for those with anxiety or other respiratory conditions, restricted breathing can become a quality of life issue.</p><p>If you're having a hard time breathing behind your mask, Kennedy said, "The size or style of the mask may be the issue."</p><p>She encourages people to try different types of face coverings to find what works for them.</p><p>"The ideal mask is snug enough to fit close to the face (no gaps) to prevent droplets from entering or exiting around the sides, but large enough that it is not restrictive or negatively impacting your ability to breathe," Kennedy said.</p><p>As part of Ivanitskaya's work, she's actually been experimenting with different materials and varying numbers of layers required to help people be comfortable in their masks while providing the most amount or protection possible.</p><p>Her team has even produced <a href="https://cutt.ly/EN-MyMaskSavesLives" target="_blank">science-based resources</a> regarding best practices for sewing washable face masks, for those interested in achieving the balance between comfort and protection.</p><p>"It's a very real issue," Ivanitskaya said. "I'm with a group of researchers who have been developing mask construction advice, and we are suggesting materials and mask designs. One of the masks we made that seemed very reasonable, I pretested on myself, wearing the mask uphill as I rode my bike."</p><p>But the same mask Ivanitskaya was able to wear without issue turned out to be impossible for her 88-year-old neighbor to keep on.</p><p>In fact, he told her he was choking inside of it. After another older neighbor reported the same experience, Ivanitskaya turned to the research and discovered evidence of diminished lung capacity among older adults.</p><p>That was when she started experimenting with finding the sweet spot between protection and tolerability for those who may not be able to breathe as easily from behind a mask.</p><p>What she discovered is that different people have different levels of tolerability when it comes to mask wear — and factors like outside temperatures, whether the wearer also uses glasses, and even nose size can all play a role.</p><p>Finding a mask you can comfortably keep on should be the ultimate goal, even if it doesn't provide exactly the same level of protection as someone who may be able to tolerate more layers and a tighter seal.</p>
Functional — and Fashionable<p>But it's not just improving comfort that face mask designers are now focusing on. Many are also trying to create masks people actually want to wear — masks others might find as an aesthetically pleasing and fun way to accessorize.</p><p>If you think that sounds crazy, just remember: Sunglasses and hats once started out as items meant to simply protect the wearer from the sun.</p><p>They've now evolved into fashion accessories providing countless options to choose from.</p><p>"Many businesses, small and large, have taken the opportunity to make and sell cloth face covers. A wide variety of styles and designs are already available," Bell said. "We're already seeing a lot of people not only wearing cloth face coverings, but making a design or fashion statement with their choice of cover."</p><p>Whether it's the design you choose or the way you fasten your mask to your face (with a popular debate now ensuing over whether ear loops or clasps behind the head are better), you have an opportunity to make a statement with the mask you wear — and protect others in style.</p>

Should people be forced to wear face masks in public? That's the question facing governments as more countries unwind their lockdowns. More than 30 countries have made masks compulsory in public, including Germany, Austria and Poland. This is despite the science saying masks do little to protect wearers, and only might prevent them from infecting other people.
The Great Shutdown<p><a href="https://www.oxfordscholarship.com/view/10.1093/oso/9780198819660.001.0001/oso-9780198819660" target="_blank">In the U.S.</a>, no disease in history led to such intrusive restrictions as the great influenza. These included closures of schools, churches, soda fountains, theatres, movie houses, department stores and barber shops, and regulations on how much space should be allocated to people in indoor public places.</p><p>There were fines against coughing, sneezing, spitting, kissing and even talking outdoors — those the Boston Globe called "big talkers." Special influenza police were hired to round up children playing on street corners and occasionally even in their own backyards.</p><p>Restrictions were similarly tough in Canada, Australia and South Africa, though much less so in the UK and continental Europe. Where there were such restrictions, the public accepted it all with few objections. Unlike the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4422154/" target="_blank">long history of cholera</a>, especially in Europe, or <a href="https://www.jstor.org/stable/312523" target="_blank">the plague</a> in the Indian subcontinent from 1896 to around 1902, no mass violence erupted and blame was rare — even against Spaniards or minorities.</p><p>Face masks came closest to being the measure that people most objected to, even though masks were often popular at first. The Oklahoma City Times in October 1918 described an "army of young women war workers" appearing "on crowded street cars and at their desks with their faces muffled in gauze shields." From the same month, The Ogden Standard reported that "masks are the vogue," while the Washington Times told of how they were becoming "general" in Detroit.</p>
Shifting Science<p>There was scientific debate from the beginning about whether the masks were effective, but the game began to change after French bacteriologist <a href="https://www.famousscientists.org/charles-nicolle/" target="_blank">Charles Nicolle</a> discovered in October 1918 that the influenza was much smaller than any other known bacterium.</p><p>The news spread rapidly, even in small-town American newspapers. Cartoons were published that read, "like using barbed wire fences to shut out flies." Yet this was just at the point that mortality rates were ramping up in the western states of the U.S. and Canada. Despite Nicolle's discovery, various authorities began making masks compulsory. San Francisco was the first major U.S. city to do so in October 1918, continuing on and off over a three-month period.</p><p>Alberta in Canada did likewise, and New South Wales, Australia, followed suit when the disease arrived in January 1919 (the state basing its decision on scientific evidence older than Charles Nicolle's findings). The only American state to make masks mandatory was (briefly) California, while on the east coast and in other countries including the UK they were merely recommended for most people.</p>
San Francisco gathering, 1918. Wikimedia<p>Numerous photographs, like the one above, survive of large crowds wearing masks in the months after Nicolle's discovery. But many had begun to distrust masks, and saw them as a violation of civil liberties. According to a November 1918 front page report from Utah's Garland City Globe:</p><blockquote>The average man wore the mask slung to the back of his neck until he came in sight of a policeman, and most people had holes cut into them to stick their cigars and cigarettes through.<br></blockquote>
Disobedience Aplenty<p>San Francisco saw the creation of the <a href="https://www.theguardian.com/world/2020/apr/29/coronavirus-pandemic-1918-protests-california" target="_blank">anti-mask league</a>, as well as protests and civil disobedience. People refused to wear masks in public or flaunted wearing them improperly. Some went to prison for not wearing them or refusing to pay fines.</p><p>In Tucson, Arizona, a banker insisted on going to jail instead of paying his fine for not masking up. In other western states, judges regularly refused to wear them in courtrooms. In Alberta, "scores" were fined in police courts for not wearing masks. In New South Wales, reports of violations flooded newspapers immediately after masks were made compulsory. Not even stretcher bearers carrying influenza victims followed the rules.</p><p>England was different. Masks were only advised as a precautionary measure in large cities, and then only for certain groups, such as influenza nurses in Manchester and Liverpool. Serious questions about efficacy only arose in March 1919, and only within the scientific community. Most British scientists now united against them, with the Lancet calling masks a "dubious remedy."</p><p>These arguments were steadily being bolstered by statistics from the US. The head of California's state board of health had presented late 1918 findings from San Francisco's best run hospital showing that 78 percent of nurses became infected despite their careful wearing of masks.</p><p>Physicians and health authorities also presented statistics comparing San Francisco's mortality rates with nearby San Mateo, Los Angeles and Chicago, none of which had made masks compulsory. Their mortality rates were either "no worse" or less. By the end of the pandemic in 1919, most scientists and health commissions had come to a consensus <a href="https://theconversation.com/should-everyone-be-wearing-face-masks-its-complicated-135548" target="_blank">not unlike ours</a> about the benefits of wearing masks.</p><p>Clearly, many of these details are relevant today. It's telling that a frivolous requirement became such an issue while more severe rules banned things like talking on street corners, kissing your fiancé or attending religious services — even in the heart of America's Bible belt.</p><p>Perhaps there's something about masks and human impulses that has yet to be studied properly. If mass resistance to the mask should arise in the months to come, it will be interesting to see if new research will produce any useful findings on phobias about covering the face.</p>

If you're one of those people cooped up safely at home, with creative energy and free time to spare—count yourself lucky. Here, we've rounded up a list of two dozen environmental projects that can make your time indoors, or right outside, a little brighter. Whether you're ready to start rescuing more of your kitchen scraps, sewing your own cloth napkins, or documenting those backyard butterflies, we hope these simple green ideas will provide a calming means of coping during these unprecedented times. Have fun and stay safe.
Experiment in the Kitchen<p><strong>Spice up mealtime with recipes from </strong><a href="https://savethefood.com/recipes/" target="_blank">Save the Food</a> that will also help prevent your food from going to waste. Make a fromage fort to spread on your crackers, or "scraps falafel" to use up wrinkly onions and wilted herbs. And for dessert, how about some <a href="https://savethefood.com/recipes/leftover-mashed-potato-apple-cider-donuts" target="_blank">leftover mashed potato apple cider donuts</a>? </p><p><strong>Rescue wilting herbs.</strong> Make <a href="https://savethefood.com/storage" target="_blank">herb oil ice cubes</a><a href="https://savethefood.com/storage" target="_blank"> by </a>packing diced herbs into an ice cube tray, covering with olive oil, and freezing. Thaw for ready-made flavor in your next dish. You can also transform less-than-fresh herbs into sauces, like chimichurri or pesto, or roast them and mix with salt to create longer-lasting seasonings. </p><p><strong>Start a windowsill herb garden. </strong>You'll need some seeds or a small plant, an upcycled container like a coffee canister that leaves room for growth and drainage, and a sunny ledge. (The Herb Society of America can help you determine <a href="https://www.herbsociety.org/hsa-learn/intro-to-herbs/hsa-gardening-for-kids/light-indoor-gardens.html" target="_blank">the right dose of light and water for each species</a>.) In a few weeks' time, you'll be ready to add a sprig of fresh basil to your bowl of pasta or diced cilantro to your batch of guac.</p><p><strong>Arrange a plant-based recipe swap</strong> with friends and family, which will reduce your diet's climate impacts while creating some virtual community. (Remember: If <a href="https://www.nrdc.org/experts/sujatha-bergen/saving-planet-starts-our-plates" target="_blank">every American cut just one hamburger</a> or about a quarter pound of beef out of their diet each week, we could reduce emissions by as much as taking about 10 million cars off the road each year.)</p>
Enjoy a Dose of Nature<p><strong></strong><strong>Make your own basic bird feeder</strong> using pine cones, twine, nut butter, and birdseed. <a href="https://www.instagram.com/p/B-rxsVfAvaa/" target="_blank">This video from the Feminist Bird Club shows you one way to do it.</a> Hang it on a nearby tree you can spot through your window, then grab a pair of binoculars and do some armchair birding!</p><p><a href="https://www.nrdc.org/stories/how-and-why-be-seed-savior" target="_blank"><strong>Create an herbarium</strong></a>—a scrapbook of pressed, dried flowers or other plants. To prepare your samples, press the plant matter in a large book or between sheets of newspaper and place a weight on top. When the leaves are dry, mount them on acid-free paper to preserve them, and label each specimen on the page. You can also include illustrations, photographs, seed packets, and notes.</p><p><strong>Sharpen your naturalist ID skills.</strong> Try to identify every species of plant in your backyard or on a neighborhood walk. You can do the same for wildlife—and share your findings through <a href="https://www.projectnoah.org/" target="_blank">Project Noah</a>, a citizen science platform to discover, share, and identify wildlife.</p><p><strong>Grow new indoor plants</strong> with the use of stems and leaves, rather than seeds. Though it <a href="https://www.bbg.org/gardening/article/how_to_propagate_houseplants" target="_blank">depends on your individual plant</a> species, propagating houseplants is often as easy as cutting off a stem or leaf from an existing plant and sticking it in soil or fresh water. If it takes, a new root system should form within a few weeks—leaving you with a hearty second plant within a few more months. (Pro tip: This works for green onions too! Nearly submerge their sliced-off roots, end down, into a glass of water that you change every few days. Voilà: a nearly endless supply of scallions.)</p><p><strong>Observe monarch butterflies</strong> in your backyard and share your findings with Monarch Watch, an organization devoted to their <a href="https://www.nrdc.org/stories/monarch-butterflies-get-head-start-schoolyard" target="_blank">conservation</a>. Each year, monarchs make a remarkable 3,000-mile trek from as far north as the southern parts of Canada to the mountains of Mexico and back—but these pollinators are <a href="https://www.nrdc.org/experts/sylvia-fallon/monarch-butterfly-numbers-fall-again" target="_blank">in danger</a>. Register as one of Monarch Watch's citizen scientists to <a href="https://monarchwatch.org/calendar/?fbclid=IwAR1bawlAoraeMokwdiZa_GVONQqtDnqQxc_EM_UwzbO0zhq733PT6CQIgLc" target="_blank">help track the population's health</a>.</p><p><strong><a href="https://www.nrdc.org/stories/how-turn-your-patch-earth-barren-bountiful" target="_blank">Boost your backyard biodiversity</a>. </strong>Plant some milkweed—the main food source for monarch caterpillars and egg-laying habitat for the butterflies. Hang a bee nesting box somewhere it can get sunlight and warmth. Add a barn owl box or attach a simple roosting perch to a pole. For reptile enthusiasts, set up a small wood pile, using brush or old logs as shelter for lizards and snakes (plus fungi).</p>
Do Some Handiwork and Art Projects<p><strong>Make face masks </strong>for your friends, family, and workers on the frontlines. This <a href="https://www.cdc.gov/coronavirus/2019-ncov/downloads/DIY-cloth-face-covering-instructions.pdf" target="_blank">Center for Disease Control guide</a> breaks down different techniques. If you're comfortable sewing, you'll just need two 10-by-6-inch rectangles of fabric, two pieces of elastic, and a needle and thread for each mask. The no-sew option only requires a T-shirt and scissors. Remember: Cloth masks should be cleaned regularly (the CDC says a washing machine is sufficient) in order to remain effective.<strong></strong></p><p><strong>Get your crayons out </strong>and do some therapeutic coloring. In honor of the 50th anniversary of Earth Day and as part of a collaboration with NRDC, Studio Number One and its creative director, artist Shepard Fairey, have converted some of its archival activist artwork into <a href="http://www.studionumberone.com/free-downloads" target="_blank">black-and-white printouts for at-home coloring.</a></p><p><strong>Tackle your plastic bag stash</strong>, especially if your city or town is among those that recently banned the bag. Since current conditions may eliminate collection and recycling programs for plastic bags in your area, consider upcycling them instead. There are plenty of online tutorials for how to make outdoor pillow cushions stuffed with plastic bags, weave bags into <a href="https://www.instructables.com/id/Make-a-basket-out-of-plastic-bags/" target="_blank">sturdy baskets</a>, or wind them into jump ropes.</p>
Build Your Community<p><strong></strong><strong>Start an environmental movie club.</strong> Various apps let you host movie nights with friends online, so you can chat while you watch. You can find our recs for standout environmental films on <a href="https://www.instagram.com/p/B-QNBxqJAUR/" target="_blank">Instagram</a>—including <em>Poisoning Paradise</em>, <em>Virunga</em>, and <a href="https://www.nrdc.org/stories/how-turn-your-patch-earth-barren-bountiful" target="_blank"><em>The Biggest Little Farm</em></a>—with short summaries and tips on where you can find them online.</p><p>Document the environmental changes in your community<strong>, as they relate to climate change, through the </strong><a href="https://earthchallenge2020.earthday.org/" target="_blank"><strong>Earth Challenge </strong>2020's online portal</a>. The project will collect billions of observations in air quality, plastic pollution, and insect populations, and your insights will help promote policy change to address our warming world.</p><p><strong>Tune in to a new podcast</strong>. We recommend <a href="https://www.stitcher.com/podcast/range/hot-take-4#/" target="_blank"><em>Hot Take</em></a>, featuring NRDC's own Mary Heglar and her cohost Amy Westervelt, which takes a critical but constructive, intersectional look at how climates issues are being covered in the media.

Over a month into the lockdown and the usually bustling streets of Kalamata, a Greek city southwest of Athens traditionally known for its olives, are largely empty.
Impact on wildlife<p>Gloves, masks and other personal protective equipment (PPE) are critical for those fighting the pandemic but are also widely used by the public. Still, because they're not always disposed of properly, environmentalists fear negative consequences for wildlife and the fight against plastic pollution.</p><p>"If they're thrown on the streets, when it rains the gloves and masks will eventually end up in the sea," said Anastasia Miliou, a marine biologist and research director with the Archipelagos Institute of Marine Conservation based in Greece.</p>
How to properly recycle masks? It's a problem<p>PPE items not left to float about in the environment and the sea are not necessarily easy to deal with either, explained Joan Marc Simon, executive director of Zero Waste Europe, a Brussels-based NGO.</p><p>He points to the European recycling scheme under which retailers and producers pay for the collection and treatment of plastic packaging. As gloves aren't considered packaging, they cannot be put into household recycling bins, explained Simon.</p>
What are the sustainable choices in this pandemic?<p>The World Health Organization (WHO) told DW that regular hand-washing offers more protection against catching COVID-19 than wearing rubber gloves while out in public areas, while the <a href="https://www.cdc.gov/coronavirus/2019-ncov/prevent-getting-sick/diy-cloth-face-coverings.html" target="_blank">US Centers for Disease Control and Prevention</a> says that for the public, washable cloth masks will offer the necessary protection.</p><p>And while PPE used in medical facilities is largely non-recyclable or non-reusable, sustainable innovations are emerging.</p>
