Top 10 Vegan-Friendly Cities of 2016
1. Portland, Oregon
This year, Portland, Oregon, takes the top spot on People for the Ethical Treatment of Animals (PETA) list, thanks in part to its array of vegan and vegan-friendly restaurants. For example, Back to Eden Bakery serves up egg- and dairy-free baked goods and ice cream sundaes. Vtopian Cheese Shop & Deli offers more than 20 vegan artisan cheeses, plus vegan pepperoni melts, paninis and cheesecake. Homegrown Smoker Vegan BBQ features meat-free barbecue and cheesesteak subs, tempeh ribs and Mac No-Cheese. Portobello Vegan Trattoria prepares lobster mushroom potato cakes, ravioli, tiramisu and house-made coconut ice cream—all-vegan, of course. Petunia’s Pies & Pastries serves everything from vegan biscuits and gravy and Belgian waffles to blue corn tacos and vegan grilled cheese. Even Portland’s iconic Voodoo Doughnut now offers vegan doughnuts.
In addition to many meat-free restaurants, Portland’s all-vegan enterprises include a bed and breakfast, a summer camp, a punk-metal bar, a strip mall, a tattoo shop and even a strip club for those seeking a bit more excitement!
And that’s not all. It’s fairly easy to find vegan family medical practitioners, vegan counselors, vegan real-estate agents and other lifestyle services offered by vegans in Portland.
2. Los Angeles
The City of Angels has more listings on HappyCow—a website that lists regional vegan and vegan-friendly eateries and events—than any other U.S. city. LA is home not only to an animal rights–related museum but also to PETA’s West Coast headquarters, so you can rest assured that the vegan options have been thoroughly, um, tested.
Crossroads is a star-studded vegan restaurant that serves mouthwatering fare, including Scaloppini Marsala and artichoke oysters, prepared by celebrity chef Tal Ronnen. PETA’s pal Moby recently opened little pine, a Mediterranean-inspired vegan restaurant and donates a portion of proceeds to support our work. Gracias Madre, eLOVate Vegan Kitchen & Juicery, Ramen Hood and Sage Organic Vegan Bistro are just a handful of other popular vegan eateries in the city. Locals also love Mohawk Bend, where all menu items are vegan unless marked “NV” for “not vegan”; the all-vegan Japanese restaurant Shojin; and Spork Foods, a vegan food company and culinary school that conducts cooking demonstrations and in-home teaching. It also provides vegan culinary services, as does Veggie Fixation.
Looking for vegan guilty pleasures? Stop by Donut Friend, which offers a wide variety of unique vegan doughnuts and vegan fillings, such as coconut cream, cream cheese and more. Erin McKenna’s Bakery LA, Scoops and Donut Farm are just a few others that offer mouthwatering vegan desserts. Anyone looking for late-night vegan cheeseburgers and chili cheese fries can head over to Doomie’s Home Cookin’.
It would take ages to mention all the vegan-friendly spots in the city, but BuzzFeed’s “21 Vegan Places in Los Angeles That’ll Make You Want Seconds” should help convince you that vegan options abound in LA.
3. New York City
Is it any surprise that the Big Apple made the list again this year? In 2014, PETA named the city the most vegan-friendly spot in the nation and actor Alan Cumming presented the mayor with a sculpture of the New York skyline made entirely of vegetables.
In addition to Candle 79, Blossom and the other restaurants mentioned in PETA’s 2013 list of top vegan-friendly cities, there is by CHLOE, a vegan restaurant featuring locally obtained ingredients and Franchia Vegan Cafe, which is one of the best Asian-fusion restaurants in the country. VSPOT, which has a location right next to New York University, serves scrumptious Latin fare and Blossom du Jour, V Burger, VLife and Terri have locations throughout the city where diners can get an inexpensive and delicious vegan lunch.
Plant-based eating has become so popular that famed restaurant owner Ravi DeRossi is making his 15 bars and restaurants vegan! Vegan pop-ups appear throughout the city as chefs rent out locations to try cutting-edge new vegan fare. New York City has a plethora of animal advocates who routinely speak out against horse-drawn carriages, fur and using animals for food. There’s even a Veggie Pride Parade each April.
Detroit is going through a revitalization and vegans are being welcomed with open arms. Residents rave about Detroit Vegan Soul, which offers mac and “cheese,” “catfish” tofu, barbecue tofu sandwiches, collard greens and okra stew, among other vegan dishes. Seva serves vegan buffalo tempeh wings and Thai noodles. Whether you live in this former “meat and potatoes town” or are just passing through, be sure to check out these noteworthy vegan-friendly spots:
- Russell St. Deli offers vegan options, including a TLT—a tofu, lettuce and tomato sandwich with house-made vegan mayo. Brooklyn Street Local has a vegan Reuben with house-made seitan and vegan poutine (a Canadian dish that’s typically made with French fries and cheese curds topped with a light brown gravy).
- Detroit is known for its bar scene, so we have to mention that dive bars and fancier establishments alike are offering up delicious fare—like beloved PJ’s Lager House, which offers up vegan fried pickles, veggie burritos with spicy vegan queso and po’ boys. And popular bars Jolly Pumpkin, HopCat, Green Dot Stables and others have vegan options.
- Pizza fans can get vegan pies at well-known Buddy’s Pizza, the Majestic’s Sgt. Pepperoni’s Pizzeria & Deli and metro Detroit’s Hippies Pizza.
- Nearby Om Café serves a Quinoa Protein Salad and Loaded Vegan Mac and Chive Kitchen focuses on fresh and local products.
- You can get sweet potato–black bean chili and vegan nachos at the Shimmy Shack, among other yummy dishes and the Mac Shack will make mac ‘n’ cheese and French fries with vegan cheese sauce, upon request.
- Avalon International Breads offers several vegan items, including savory sweet potato bánh mì sandwiches; a variety of vegan muffins; and more.
5. Nashville, Tennessee
Nashville, Tennessee, is perhaps best known for country music and vegan country star Carrie Underwood has helped put vegan living on the map. It’s now easier than it’s ever been to find vegan options in the Grand Ole Opry state, which is why Nashville is on our list for the first time. You can find vegan offerings everywhere, from Vegan Vee bakery to Avo, a new vegan restaurant that offers vegan wine and tree nut cheeses. Coco Greens café went from vegetarian to vegan in 2014 and the ever-popular vegan-friendly Sunflower Vegetarian Cafe has “more vegan and gluten-free options than you can shake a stick at!” Frothy Monkey lists tofu as a meat, The Urban Juicer is one of the many spots offering almond and soy milk and Mad Donna’s offers a vegan black-bean burger.
You can get vegan cheese pizza at many pizza places, including Five Points Pizza, Mellow Mushroom and Two Boots. You can find vegan offerings at other restaurants, too. Bagel Face Bakery offers agave and vegan sausage. The Post East offers a chickpea salad sandwich, vegan Caesar salad, buffalo-style tofu and vegan ranch dressing. Sloco serves a vegan meatball sub and a seitan sandwich. And MyVeggieChef is Nashville’s popular plant-based meal-delivery service.
6. San Diego
Los Angeles isn’t the only vegan-friendly city in California. A lot of restaurants in San Diego now offer vegan options. Take, for example, Civico 1845 in Little Italy, which offers an entire vegan menu, including desserts. And if dessert is your thing, you’ll probably also like Moncai Vegan, a vegan restaurant and bakery that sells vegan cupcakes, vegan cinnamon rolls and vegan doughnuts. Speaking of vegan doughnuts, they can also be found at Donut Panic.
Who’s up for Mexican? Ranchos Cocina is a vegan-friendly Mexican restaurant that offers vegan cheese and a variety of faux meats and be sure to check out Casa de Reyes, a restaurant in Old Town. Pokez Mexican eatery also offers various vegan options. If you’re in the mood for Thai, try Veganic or the vegan-friendly Plumeria. If you’re looking for vegan fast food, try Evolution and Plant Power Fast Food. Want fresh fruits and veggies? Check out Sol Cal Cafe, a vegan-friendly market and juice joint, which was created in part by former NFL great Jacob Bell.
Kindred is a vegan death-metal cocktail bar that serves everything from Seared Cauliflower Steak to Memphis BBQ Jackfruit sandwiches and Peace Pies is a vegan spot that practices a “strict zero waste” policy. Other vegan-friendly places in San Diego include The Purple Mint Vegetarian Bistro and Sipz Vegetarian Fuzion Cafe.
Because California has had a drought for so long, local activists persuaded many “meaty” restaurants in town to put up signs encouraging customers to choose their vegan options as a way to help conserve water. Vegan food is everywhere you look in San Diego, including at Petco Park, which made PETA’s annual list of vegan-friendly stadiums last year and peta2 named the University of California–San Diego a vegan-friendly campus in 2015.
What’s paradise without vegan food? Hawaii’s capital is becoming more and more vegan-friendly every year and it’s currently home to these and other vegan-friendly restaurants:
- Simple Joy is all-vegan and offers barbecue drumsticks, vegetable lasagne and more.
- Greens & Vines is a gourmet vegan restaurant offering vegan sushi, “living” lasagne, vegan cheesecake and more.
- Peace Cafe is an all-vegan café serving up curry egg-free salad, teriyaki tempeh sandwiches, vegan Caesar salad, homemade vegan ice cream and more.
- Govinda’s Under the Banyan is an inexpensive vegetarian buffet with many vegan options and a botanical atmosphere.
- Downbeat Diner & Lounge is a sports bar that offers vegan hot wings, vegan barbecue wings, a vegan burger and more. The place isn’t exclusively vegan, but every menu item can reportedly be made vegetarian or vegan.
- Ruffage Natural Foods is a casual spot that offers vegan chili, a tofu scrambler and other healthful vegan options.
- Blue Tree serves several vegan options, including a tofu curry wrap and oatmeal made with almond milk.

8. Austin, Texas
It may be in cattle country, but Austin, Texas, has plenty of places that serve cow-free food. It even took the top spot on PETA’s list of vegan-friendly cities in 2013. In addition to all the vegan food trucks, vegan-friendly restaurants and the vegan ice cream parlor that we raved about in 2013, there is now Counter Culture restaurant, which serves meat-free and dairy-free food featuring produce from local farmers. Locals love vegan food trucks, The Vegan Yacht, The Vegan Nom, Guac N Roll and BBQ Revolution. And there are even more all-vegan businesses: Arlo’s, Bistro Vonish, Capital City Bakery, Casa de Luz, Cool Beans, Happy Vegan Baker, Rabbit Food Grocery, Skull and Cakebonesand Unity Vegan Kitchen.
Not only is Seattle full of vegan-friendly coffee houses and cafés, including 701 Coffee and Chaco Canyon Organic Café, it also has an all-vegan grocery store called Vegan Haven. Vegan options are available throughout the city, including at Pizza Pi, the country’s first vegan pizza place; Plum Bistro; Cycle Dogs, a bicycle-pulled vegan hot dog cart; Wayward Vegan Cafe; and Thrive, which serves raw and vegan food that’s gluten- and peanut-free. It’s clear that no amount of rain can dampen Seattle’s hard-core vegan spirit!
10. Richmond, Virginia
Virginia’s “River City” is packed with many vegan-friendly eateries. Among them is Strange Matter, a popular hangout that has vegan nachos, vegan mac ‘n’ cheese, vegan chicken cheesesteak sandwiches and much more. Phoenix Garden, a Vietnamese noodle house featuring plenty of filling vegan food is another not-to-be-missed restaurant. Harrison St. Café, Ipanema and 821 Café all offer mouthwatering vegan options. For the Love of Chocolate even caters to vegan chocoholics.

A key part of the United States' clean energy transition has started to take shape, but you may need to squint to see it. About 2,000 wind turbines could be built far offshore, in federal waters off the Atlantic Coast, in the next 10 years. And more are expected.
Threats to Birds<p>One of the gravest threats facing birds is climate change, according to Audubon, which found that rising temperatures threaten <a href="https://www.audubon.org/2019climateissue" target="_blank" rel="noopener noreferrer">nearly two-thirds of North America's bird species</a>. That's why the impending development of offshore wind is a good thing, says Shilo Felton, a field manager in the organization's Clean Energy Initiative, but it also comes with dangers to birds that need to be better studied and mitigated.</p><p>The most obvious risk comes from birds colliding with spinning turbine blades. But offshore wind developments can also displace birds from foraging or roost sites, as well as migratory pathways.</p><p>Along the Atlantic Coast four imperiled species are of top concern to conservationists: the endangered piping plover, red knot, roseate tern and black-capped petrel, which is being considered for listing under the Endangered Species Act.</p><p>"Those four species are of utmost importance to make sure that we understand the impacts," says Felton. "But beyond that there are many species that are protected under the Migratory Bird Treaty Act and the Fish and Wildlife Conservation Act that could potentially see more impacts from offshore wind."</p><p>Northern gannets, for example, are at risk not just for collision but <a href="https://www.researchgate.net/publication/308703197_Possible_impacts_of_offshore_wind_farms_on_seabirds_a_pilot_study_in_Northern_Gannets_in_the_southern_North_Sea" target="_blank">habitat displacement</a>.</p>
A northern gannet flying along Cape May, N.J. Ann Marie Morrison / CC BY-NC-ND 2.0<p>"There's <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320716303196" target="_blank">some evidence</a> that they just won't use areas where turbines are, but that also excludes them from key foraging areas," says Felton. Researchers are still studying what this may mean for the birds. But a <a href="https://www.sciencedirect.com/science/article/pii/S0141113620305304" target="_blank">study</a> published in December 2020 conducted at Bass Rock, Scotland — home to the world's largest northern gannet colony — found that wind developments could reduce their growth rate, though not enough to cause a population decline.</p><p>Other birds, such as great cormorants and European shags, are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320716303196" target="_blank">attracted to wind developments</a> and use the infrastructure to rest while opening up new foraging areas farther from shore.</p><p>"There's plenty of potential for a bird to use a wind farm and still to avoid the turbines themselves," says Felton.</p><p>Birds like pelicans, however, are less versatile in their movements and are at particular risk of collision because of their flight pattern, she says.</p><p>But how disruptive or dangerous offshore turbines will be along the East Coast isn't yet known.</p><p>Federal and state agencies, along with nongovernmental organizations, says Felton, have done good research to try to better understand those potential impacts. "But these are all theoretical, because we don't have a lot of offshore wind yet in the United States."</p>
Threats to Ocean Life<p>Birds aren't the only wildlife of concern. More development in ocean waters could affect a litany of marine species, some of which are already facing other pressures from overfishing, pollution, habitat destruction and climate change.</p><p>Scientists have found that marine mammals like whales and dolphins could be disturbed by the jarring sounds of construction, especially if pile driving is used to hammer the steel turbine platform into the seafloor.</p><p>The noises, though short-lived, could impede communication between animals, divert them from migration routes or cause them to seek less suitable areas for feeding or breeding. Research from Europe found that harbor porpoises, seals and dolphins may avoid development areas during construction. In most, but <a href="https://iopscience.iop.org/article/10.1088/1748-9326/7/4/045101" target="_blank">not all cases</a>, the animals were believed to have returned to the area following construction.</p><p>The biggest concern for conservation groups in the United States is the critically endangered North American right whale. There are fewer than 400 remaining, and the species' habitat overlaps with a number of planned wind development areas along the East Coast.</p><p>"Offshore wind is in no way the cause of the challenges the whales face, but it's going to be another pressure point," says John Rogers, senior energy analyst for the Union of Concerned Scientists.</p><p>Researchers aren't sure how right whales will respond to the noise from pile driving.</p><p>"But we are concerned, based on what we know about how whales react to other noise sources, that they may avoid [wind development] areas," says Kershaw.</p><p>And if that displacement causes them to miss out on important food resources, it could be dangerous for a species already on the brink.</p><p>There are a few other potential threats, too.</p><p>Ships associated with the development — more plentiful during construction — also pose a danger. In the past few years cargo ships, fishing boats and other vessels have caused half of all deaths of North Atlantic right whales.</p>

Florida Fish and Wildlife Conservation Commission / NOAA Research Permit #775-1600-10<p>And after construction, the noise from the spinning turbines will be present in the water at low decibels. "We don't quite know how the great whales will react to those sounds," says Jeremy Firestone, the director of the Center for Research in Wind at the University of Delaware.</p><p>Other marine mammals may also perceive the noise, but at low decibels it's unlikely to be an impediment, <a href="http://www.int-res.com/abstracts/meps/v309/p279-295/" target="_blank">research has found</a>.</p><p>And it's possible that wind development could help some ocean life. Turbine foundations can attract fish and invertebrates for whom hard substrates create habitat complexity — known as the "reef effect," according to researchers from the University of Rhode Island's <a href="https://dosits.org/animals/effects-of-sound/anthropogenic-sources/wind-turbine/" target="_blank" rel="noopener noreferrer">Discovery of Sound in the Sea</a> program. Exclusion of commercial fishing nearby may also help shelter fish and protect marine mammals from entanglements in fishing gear.</p>
Ensuring Safe Development<p>Despite the potential dangers, researchers have gathered a few best practices to help diminish and possibly eliminate some risks.</p><p>When it comes to ship strikes, the easiest thing is to slow boats down, mandating a speed of <a href="https://biologicaldiversity.org/w/news/press-releases/vessel-speed-limits-sought-protect-endangered-north-atlantic-right-whales-2020-08-06/" target="_blank">10 knots</a> in wind development areas, and using visual and acoustic monitoring for whales.</p><p>Adjusting operations to reduce boat trips between the shore and the wind development will also help. A new series of service operating vessels can allow maintenance staff to spent multiple days onsite, says Kershaw, cutting down on boat traffic.</p><p>For construction noise concerns, developers can avoid pile driving during times of the year when whales are present. And, depending on the marine environment, developers could use "quiet foundations" that don't require pile driving. These include gravity-based or suction caisson platforms.</p><p>Floating turbines are also used in deep water, where they're effectively anchored in place — although that poses its own potential danger. "We have concerns that marine debris could potentially become entangled around the mooring cables of the floating arrays and pose a secondarily entanglement risk to some species," says Felton, who thinks more research should be conducted before those become operational in U.S. waters — a process that's already underway in Maine, where a <a href="https://composites.umaine.edu/2020/08/05/diamond-offshore-wind-rwe-renewables-join-the-university-of-maine-to-lead-development-of-maine-floating-offshore-wind-demonstration-project/" target="_blank" rel="noopener noreferrer">demonstration project is being built</a>.</p><p>If loud noises are unavoidable during construction, noise-reducing technologies such as bubble curtains can help dampen the sound. And scheduling adjacent projects to conduct similar work at the same time could limit the duration of disturbances.</p>

Vattenfall / Ulrich Wirrwa / CC BY-NC-ND 2.0<p>Once turbines become operational, reducing the amount of light on wind platforms or using flashing lights could help deter some seabirds, NRDC <a href="https://www.nrdc.org/sites/default/files/harnessing-wind-advance-wind-power-offshore-ib.pdf" target="_blank" rel="noopener noreferrer">researchers reported</a>. And scientists are exploring using ultrasonic noises and ultraviolet lighting to keep bats away. "Feathering," or shutting down the turbine blades during key migration times, could also help prevent fatalities.</p><p>"We need to make sure that offshore wind is the best steward it can be of the marine ecosystem, because we want and expect it to be a significant part of the clean energy picture in some parts of the country," says Rogers. "We also have to recognize that we're going to learn by doing, and that some of these things we're going to figure out best once we have more turbines in the water."</p><p>That's why environmental groups say it's important to establish baseline information on species before projects begin, and then require developers to conduct monitoring during construction and for years after projects are operational.</p><p>Employing an "adaptive management framework" will ensure that developers can adjust their management practices as they go when new information becomes available, and that those best practices are incorporated into the requirements for future projects.</p>
Putting Research Into Action<p>Advancing these conversations at the federal level during the Trump administration, though, has been slow going.</p><p>"We didn't really have any productive discussions with the administration in the last four years," says Kershaw.</p><p>And when it comes to birds, Felton says the Bureau of Ocean Energy Management's recently completed "draft cumulative environmental impact statement" covering offshore wind developments had a lot of good environmental research, but little focus on birds.</p><p>"Part of that comes from the current administration's interpretation of the Migratory Bird Treaty Act," she says.</p><p>President Trump has been hostile to both wind energy <em>and</em> birds, <a href="https://www.nytimes.com/2021/01/05/climate/trump-migratory-bird-protections.html" target="_blank">and finished gutting the Migratory Bird Treaty Act</a> in his administration's the final days, removing penalties for companies whose operations kill migratory birds.</p><p>There's hope that the Biden administration will take a different approach. But where the federal government has been lacking lately, Kershaw says, they've seen states step up.</p><p>New York, for example, has established an <a href="https://www.nyetwg.com/" target="_blank" rel="noopener noreferrer">Environmental Technical Working Group</a> composed of stakeholders to advise on environmentally responsible development of offshore wind.</p><p>The group is led by the New York State Energy Research and Development Authority, but it isn't limited to the Empire State. It's regional in focus and includes representatives from wind developers with leases between Massachusetts and North Carolina; state agencies from Massachusetts to Virginia; federal agencies; and science-based environmental NGOs.</p><p>New York's latest solicitation for clean energy projects includes up to 2,500 megawatts of offshore wind and <a href="https://www.nyetwg.com/announcements" target="_blank" rel="noopener noreferrer">requires developers</a> to contribute at least $10,000 per megawatt for regional monitoring of fisheries and other wildlife.</p><p>Environmental groups have also worked directly with developers, including an agreement with Vineyard Wind — an 800-megawatt project off the Massachusetts coast that could be the first utility-scale wind development in federal waters — to help protect North Atlantic right whales.</p><p>The agreement includes no pile driving from Jan. 1 to April 30, ceasing activities at other times when whales are visually or acoustically identified in the area, speed restrictions on vessels, and the use of noise reduction technology, such as a bubble curtain during pile driving.</p><p>"The developers signed the agreement with us, and then they incorporated, most, if not all of those measures into the federal permitting documents," says Kershaw. "The developers really did a lot of bottom up work to make sure that they were being very protective of right whales."</p><p>Environmental groups are in talks with other developers on agreements too, but Felton wants to see best practices being mandated at the federal level.</p><p>"It's the sort of a role that should be being played by the federal government, and without that it makes the permitting and regulation process less stable and less transparent," she says." And that in turn slows down the build out of projects, which is also bad for birds because it doesn't help us address and mitigate for climate change."</p><p>Kershaw agrees there's a lot more work to be done, especially at the federal level, but thinks we're moving in the right direction.</p><p>"I think the work that's been done so far in the United States has really laid the groundwork for advancing this in the right way and in a way that's protective of species and the environment," she says. "At the same time, it's important that offshore wind does advance quickly. We really need it to help us combat the worst effects of climate change."</p><p><em><a href="https://therevelator.org/author/taralohan/" target="_blank" rel="noopener noreferrer">Tara Lohan</a> is deputy editor of The Revelator and has worked for more than a decade as a digital editor and environmental journalist focused on the intersections of energy, water and climate.

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.
Blackpoll warbler. PJTurgeon / Wikipedia<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>

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>
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>
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.

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.
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>
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>

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>
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>
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>
