Maybe a gas station right around the corner? You likely already know many of the places that release air pollution near you.</p><p>When state or local regulators work with community members to find out what air pollution sources communities are worried about, the partnership can lead to a system that better <a href="https://doi.org/10.2190/D7QX-Q3FQ-BJUG-EVHL" rel="nofollow">serves the public and reduces injustice</a>.</p><p>For example, partnerships between community advocates, scientists and regulators in heavily polluted and marginalized <a href="https://doi.org/10.2190/D7QX-Q3FQ-BJUG-EVHL" rel="nofollow">neighborhoods in New York and Boston</a> have had big benefits. These partnerships resulted in both better scientific knowledge about how air pollution is connected to asthma and the placement of air monitors in neighborhoods impacted the most.</p><p>In Colorado, the process to choose the five priority air toxics included consulting with multiple stakeholders.

The act also regulates <a href="https://www.epa.gov/haps/what-are-hazardous-air-pollutants" rel="nofollow">188 hazardous air pollutants</a>.</p><p>Individual states are free to develop their own regulations, and several, including <a href="https://ww2.arb.ca.gov/resources/documents/ab-1807-toxics-air-contaminant-identification-and-control" rel="nofollow">California</a> and <a href="https://www.pca.state.mn.us/get-engaged/air-toxics-regulations" rel="nofollow">Minnesota</a>, already have. States can set standards that are more health-protective than those in place nationally.</p><p>Four of the five chemicals prioritized by Colorado are regulated federally. The fifth chemical, hydrogen sulfide, is not included on the U.S. Environmental Protection Agency’s <a href="https://www.epa.gov/haps/initial-list-hazardous-air-pollutants-modifications" rel="nofollow">hazardous air pollutant list</a>, but Colorado has decided to regulate it as an air toxic.</p><p>State-level regulation is important because states can focus on air toxics specific to their state to make sure that the communities most exposed to air pollution are protected. One way to do this is to place air pollution monitors in the communities experiencing the worst air pollution.</p><p>For example, Colorado is placing <a href="https://cdphe.colorado.gov/air-toxics/trends#COATTS" rel="nofollow">six new air quality monitors</a> in locations around the state to measure concentrations of the five priority air toxics. It will also use an existing monitor in Grand Junction to measure air toxics. Two of the new monitors, located in Commerce City and La Salle, began operating in January 2024. The remainder <a href="https://cdphe.colorado.gov/public-protections-from-TACs/monitoring" rel="nofollow">will start monitoring the air</a> by July 2025.</p><p>When Colorado chose the sites, it prioritized communities that are overly impacted by social and environmental hazards. To do this, officials used indexes like the <a href="https://cdphe.colorado.gov/enviroscreen" rel="nofollow">Colorado EnviroScreen</a>, which combines information about pollution, health and economic factors to identify communities that <a href="https://cdphe.colorado.gov/ej/learn" rel="nofollow">are overly burdened by hazards</a>.</p><p>The Commerce City monitor is located in Adams City, a neighborhood that has some of the worst pollution in the state. The site has <a href="https://www.cohealthmaps.dphe.state.co.us/COEnviroscreen_2/#data_s=id%3Awidget_304_output_config_1%3A0%2Cid%3AdataSource_1-1930c792877-layer-66%3A2358" rel="nofollow">air toxics emissions</a> that are worse than 95% of communities in Colorado.</p><h2>Air toxics and health</h2><p>The five air toxics that Colorado selected all have negative impacts on health.

The weight of the ice sheet created immense pressures that forced this sandy fluid into bedrock that had already been weakened over millions of years. Similar to fracking for natural gas or oil today, the pressure cracked the rocks and pushed the sandy meltwater in, eventually creating the injectites we see today.</p><p><strong>Clues to another geologic puzzle</strong></p><p>Not only do the new findings further cement the global Snowball Earth hypothesis, but the presence of Tava injectites within weak, fractured rocks once overridden by ice sheets provides clues about other geologic phenomena.</p><p>Time gaps in the rock record created through erosion and <a href="https://geology.utah.gov/map-pub/survey-notes/glad-you-asked/unconformity/#:%7E:text=Unconformities%2520are%2520a%2520type%2520of,the%2520deposition%2520of%2520sediments%2520anew" rel="nofollow">referred to as unconformities</a> can be seen today across the United States, most famously at the Grand Canyon, where in places, over a billion years of time is missing. Unconformities occur when a sustained period of erosion removes and prevents newer layers of rock from forming, leaving an unconformable contact.</p><p>Our results support that a Great Unconformity near Pikes Peak must have been formed prior to Cryogenian Snowball Earth. That’s at odds with hypotheses that attribute the formation of the Great Unconformity to <a href="https://doi.org/10.1073/pnas.1804350116" rel="nofollow">large-scale erosion</a> by Snowball Earth ice sheets themselves.</p><p>We hope the secrets of these elusive Cryogenian rocks in Colorado will lead to the discovery of further terrestrial records of Snowball Earth.

According to&nbsp;<a href="https://www.ohchr.org/en/documents/country-reports/nepal-conflict-report" target="_blank" rel="nofollow">United Nations estimates</a>, the conflict resulted in the deaths of 13,000, with 1,300 people still missing and an unknown number of torture and conflict-related sexual violence victims.</p><p>The People’s War ended with the signing of the&nbsp;<a href="https://peaceaccords.nd.edu/accord/comprehensive-peace-agreement" target="_blank" rel="nofollow">Comprehensive Peace Accord</a>&nbsp;that, among other obligations, required the Nepal government to create a high-level truth commission.</p><p>To date, the commissions have completed two rounds. The first, which collected the majority of the victim cases, began with a two-year mandate in 2015 that the government extended by an additional year three times. The second round, mandated from 2020 to 2022, was shut down for months due to COVID-19.</p><p>The commissions were tasked with three main objectives: to reveal the truth about gross human rights violations; to create an environment of peace, trust and reconciliation; and to make legal recommendations for victim reparations and perpetrators from the conflict.</p><p>However, despite seven years of work, little progress toward any of these objectives has been made. No case investigations have been completed, no perpetrators have been held accountable, and no victim reparations have been distributed. Reconciliation in a country that still bears the scars of conflict remains a distant thought.</p><p>From 2022 to 2023, I conducted research in Nepal about the country’s transitional justice process. During my research, I heard people refer to Nepal’s prolonged process as “a judicial merry-go-round,” “Groundhog Day” and “<a href="https://nepalitimes.com/opinion/transitional-injustice-in-nepal" target="_blank" rel="nofollow">transitional injustice</a>.”</p><p>Many Nepali people I spoke to believe that the government has strategically prolonged the transitional justice process to avoid accountability, hoping that people will eventually tire of the process and forget. Indeed, a heavy cloud of hopelessness and frustration had settled over the commissions as legal and resource limitations and political biases plagued the first two rounds, severely slowing progress and impairing the commissions’ functionality and local trust.</p><p><strong>Justice ‘adjourned’</strong></p><p>In 2022, I interviewed a conflict victim in the rolling hills of Rolpa, in the country’s west, where&nbsp;<a href="https://www.recordnepal.com/a-journey-through-the-maoist-heartland" target="_blank" rel="nofollow">the conflict began</a>. She had submitted her case to the Truth and Reconciliation Commission seven years before but had heard nothing since. “In a way, our complaints are in adjournment,” she said. “They have not ended, yet they are not being forwarded either.”</p><p>She was one of approximately&nbsp;<a href="https://kathmandupost.com/national/2023/04/29/absence-of-law-is-denying-conflict-victims-of-sexual-violence-access-to-justice-report" target="_blank" rel="nofollow">300 women</a>&nbsp;who officially submitted a case of conflict-related sexual violence to the TRC.</p><div class="feature-layout-callout feature-layout-callout-xlarge"> <div class="ucb-callout-content"><div class="image-caption image-caption-"><p> </p><div class="imageMediaStyle medium_750px_50_display_size_"> <img loading="lazy" src="/asmagazine/sites/default/files/styles/medium_750px_50_display_size_/public/article-image/woman_on_nepal_rooftop.jpg?itok=32cVLCeZ" width="750" height="482" alt="Woman sitting on roof in Nepal"> </div> <p>A woman looks over the village of Thabang, Rolpa, Nepal.

While Lama was&nbsp;<a href="https://www.theguardian.com/law/2016/sep/06/nepalese-officer-col-kumar-lama-cleared-torturing-maoist-detainees" target="_blank" rel="nofollow">acquitted there due to a lack of evidence</a>, the threat of universal jurisdiction for war crimes perpetrators in Nepal&nbsp;<a href="https://myrepublica.nagariknetwork.com/news/leaders-may-face-arrest-abroad-if-tj-issues-not-resolved-australia-envoy/" target="_blank" rel="nofollow">still looms</a>&nbsp;for those in positions of power during the civil war.</p><p><strong>A contested step forward</strong></p><p>But a&nbsp;<a href="https://www.reuters.com/world/asia-pacific/nepal-pm-dahal-loses-parliamentary-vote-confidence-2024-07-12/" target="_blank" rel="nofollow">recent change in the political leadership of Nepal</a>&nbsp;and the passing of the new law, which amended the&nbsp;<a href="https://missingpersons.icrc.org/library/enforced-disappearances-enquiry-truth-and-reconciliation-commission-act-2071-2014-nepal" target="_blank" rel="nofollow">Enforced Disappearances Enquiry, Truth and Reconciliation Commission Act</a>, mark an opportunity for the government to move beyond transitional justice lip service.</p><p>Under the amended law, a third round of appointed commissioners will operate for a period of four years – hopefully enough time to complete their unaccomplished mandates. A government committee is&nbsp;<a href="https://kathmandupost.com/politics/2024/09/04/ground-laid-to-begin-transitional-justice-work-before-dashain" target="_blank" rel="nofollow">working to appoint</a>&nbsp;new truth commissioners before the country’s major holiday Dashain in October 2024. The amended act also provides for creating specialized subunits within the TRC—concerning truth-seeking and investigations, reparations, sexual violence and rape, and victims coordination—that could potentially improve the streamlining of resources and move some of these stalled parts of the commissions forward.</p><div class="feature-layout-callout feature-layout-callout-xlarge"> <div class="ucb-callout-content"><div class="image-caption image-caption-"><p> </p><div class="imageMediaStyle medium_750px_50_display_size_"> <img loading="lazy" src="/asmagazine/sites/default/files/styles/medium_750px_50_display_size_/public/article-image/maoist_victims_protest.jpg?itok=Dk1DHV1u" width="750" height="466" alt="Protesters in Nepal"> </div> <p>Maoist victims protest&nbsp;in Kathmandu, Nepal, in 2023.

Pyakurel stressed the need for Nepali civil society, alongside the international community, to pressure the government to fulfill its promises of a victim-centric implementation.</p><p>“You can make whatever law you want, but it is how you implement it that really matters,” Pyakurel told me. “Although the law is different, if the mentality remains the same, then nothing will change.”</p><p>The revival of Nepal’s truth commissions provides the government a chance to demonstrate a commitment to a transparent and legitimate process. But I believe it must move beyond the transitional justice ritualism of the previous two commissions to actually provide justice and acknowledgment for the country’s civil war victims.</p><p><em>Top image:&nbsp;A Nepali&nbsp;man looks at photographs of people 'disappeared' during Nepal's civil war in Kathmandu Aug.&nbsp;30, 2017.

In June and July 2024, in cooperation with the Kyiv International Institute for Sociology (<a href="https://www.kiis.com.ua/?lang=eng" target="_blank" rel="nofollow">KIIS</a>), we conducted a telephone public opinion survey of 2,200 respondents representative of the adult population of government-controlled areas of Ukraine.

But our survey findings suggest people are worried about war weariness among their fellow Ukrainians. It also suggests that there is growing, if reluctant, support for negotiations and territorial concessions.</p><p><strong>Open to compromise</strong></p><p>Attitudes among Ukrainians toward territorial concessions have also started to shift—but only slightly. Most people have opposed giving up land since 2014, but&nbsp;<a href="https://kiis.com.ua/?lang=eng&amp;cat=reports&amp;id=1421&amp;page=1" target="_blank" rel="nofollow">KIIS’s own regular omnibus survey</a>&nbsp;provides evidence of growing recognition, now shared by one-third of Ukrainians, that territorial concessions may be necessary.</p><p>In June-July 2024 we repeated a question we asked in Oct. 2022 on territorial concessions, shown in the figure below. “All choices about what to do during this current Russian aggression have significant, but different, costs. Knowing this, which of the following four choices should the Ukraine government take at this time?”</p><p>The biggest change was this: in 2022, 71% of respondents supported the proposition to “continue opposing Russian aggression until all Ukrainian territory, including Crimea, is liberated," but in 2024 the support for that option had dropped to 51%.</p><p>In 2022, just 11% agreed with “trying to reach an immediate ceasefire by both sides with conditions and starting intensive negotiations." In 2024, that share had increased to 31%.</p><p>But there are differences in how people look at these choices. Much depends on whether they have been displaced (though whether they lost family members or friends does not seem to make a difference), whether they worry about war fatigue among their fellow Ukrainians, and whether they are optimistic or pessimistic about western support.</p><p>There is more at stake in this war than territory—not least, saving lives, ensuring Ukraine’s sovereignty, and protecting the country’s future security. KIIS’s own recent research has shown that in a&nbsp;<a href="https://kiis.com.ua/?lang=eng&amp;cat=reports&amp;id=1421&amp;page=1" target="_blank" rel="nofollow">hypothetical negotiation scenario</a>, people’s views on the importance of preserving territorial integrity might depend on how any possible deal might safeguard other things they care about.</p><p>For two and a half years, the brutal war has affected everyday&nbsp;<a href="https://www.nytimes.com/2024/07/31/world/europe/ukraine-russia-peace-mood.html?unlocked_article_code=1._U0.ndHL.XwhmgrySahWP&amp;smid=url-share" target="_blank" rel="nofollow">lives of Ukrainians</a>, and many (43%) believe that the war will last at least another year. Most of the respondents in our survey had not been physically injured in Russian violence (12% had), but about half had witnessed Russian violence, and most had lost a close family member or friend (62%). About one-third had been displaced from their homes.</p><p>Consistent with an increasing number of reports, the survey shows growing recognition of war fatigue. Rather than asking directly about whether respondents felt this themselves, we asked whether they worried about it among fellow Ukrainians. The results were revealing: 58% worry “a lot” and 28% worry “a little," whereas only 10% report that they do not worry about war fatigue.</p><div class="feature-layout-callout feature-layout-callout-xlarge"> <div class="ucb-callout-content"><div class="image-caption image-caption-"><p> </p><div class="imageMediaStyle medium_750px_50_display_size_"> <img loading="lazy" src="/asmagazine/sites/default/files/styles/medium_750px_50_display_size_/public/article-image/ukraine_memorial.jpg?itok=-XSA0GfL" width="750" height="422" alt="Ukrainians marking second anniversary of war"> </div> <p>People in Ukraine mark the second anniversary of the beginning of the war in February.

About 19% believe western support will grow (down from 29% in 2022), while 35% believe it will stay the same (41% in 2022). Almost a quarter (24%) believe it will continue but at a lower level than now (up from 16% in 2022), and 13% believe it is unlikely to continue (up from 3% in 2022).</p><p><strong>Life or death</strong></p><p>Research from early on in the war showed that Ukrainians strongly preferred strategies that preserved the country’s political autonomy and restored the entirety&nbsp;<a href="https://theconversation.com/ukrainians-are-not-willing-to-give-up-territory-or-sovereignty-new-survey-190309" target="_blank" rel="nofollow">of its territory</a>. This would hold, “even if making concessions would reduce projected civilian and military deaths, or the risk of a nuclear strike over the next three months."</p><p>As the authors of the study pointed out: “Russian control of the government in Kyiv or of territories in the east would put the lives of many Ukrainians at risk, as it is well documented that Russia has committed widespread human rights violations in temporarily occupied territories.”</p><p>Given the war’s accumulating death toll, in our 2024 survey we designed a simple framing experiment that can give us an indication of whether considerations about loss of life may shape people’s views on negotiations. We asked half of the respondents, randomly selected, if they would accept that “Ukraine concede some of its territories to end the war”. About 24% said yes.</p><p>For the other half, we asked if they would accept that “Ukraine concede some of its territories to save lives and end the war." In that case, 34% said yes. So, if—rightly or wrongly—territorial concessions are associated with saving lives, it increases support for them.</p><p>But when asked directly in the 2024 survey if they agreed with the statement “Russia should be allowed to control the territory it has occupied since 2022," 90% disagreed. So, while there is still majority—if diminished—support for fighting to restore full territorial integrity, there is growing support for negotiations.</p><p>What we also know from our surveys is that there is very little evidence that Russia’s territorial annexations will ever have any legitimacy among Ukrainians.</p><hr><p><em><a href="/geography/john-oloughlin" target="_blank" rel="nofollow">John O'Loughlin</a> is a professor&nbsp;in the&nbsp;<a href="/geography/" target="_blank" rel="nofollow">Department of Geography</a>&nbsp;at the&nbsp;<a href="https://theconversation.com/institutions/university-of-colorado-boulder-733" target="_blank" rel="nofollow">91</a>.

This beautiful subalpine meadow, bursting with wildflowers and just 40 minutes from campus, fit the bill perfectly.</p><p>Since 2015, often joined by members of my lab, I have made weekly hikes to Elk Meadow. We visit from the first flower in May to the last in October. We observe pollinators visiting flowers at plots scattered throughout the meadow, walking the periphery to minimize trampling. The morning is the best time to visit because pollinator activity is high and thunderstorms often roll in at midday during the summer in the Rocky Mountains.</p><p><strong>Observing the network</strong></p><p>Elk Meadow is rich in biodiversity. Over the years, we have observed 7,612 interactions among over 1,038 unique pairs of species. These pairings were made by 310 species of pollinators and 45 species of plants.</p><p>Pollinators include not only a wide variety of bees, but also flies, butterflies, beetles and the occasional hummingbird.

The newfound mobility of these early riders,&nbsp;<a href="https://press.princeton.edu/books/paperback/9780691148182/the-horse-the-wheel-and-language" target="_blank" rel="nofollow">the story goes</a>, helped catalyze huge migrations across the continent, distributing ancestral Indo-European languages and cultures across Eurasia.</p><p>But what’s the actual evidence supporting the Kurgan hypothesis for the first horse domestication? Many of the most important clues come from the bones and teeth of ancient animals, via a&nbsp;<a href="https://academic.oup.com/edited-volume/28022/chapter-abstract/211834206?redirectedFrom=fulltext" target="_blank" rel="nofollow">discipline known as archaeozoology</a>.

From the outset, several studies showed that the mix of horse remains found at Botai were unlike those found in most later pastoral cultures: Botai is evenly split between male and female horses, mostly of a healthy reproductive age. Killing off healthy, breeding-age animals like this on a regular basis would devastate a breeding herd. But this demographic blend is common among animals that have been hunted. Some Botai horses even have projectile points embedded in their ribs, showing that they died through hunting rather than a controlled slaughter.</p><p>These unresolved loose ends loomed over a basic consensus linking the Botai culture to horse domestication.</p><p><strong>New scientific tools raise more questions</strong></p><p>In recent years, as archaeological and scientific tools have rapidly improved, key assumptions about the cultures of Botai, Yamnaya and the early chapters of the human-horse story have been overturned.</p><p>First, improved biomolecular tools show that whatever happened at Botai, it had little to do with the domestication of the horses that live today. In 2018, nuclear genomic sequencing revealed that Botai horses were not the ancestors of domestic horses but of&nbsp;<a href="https://www.scientificamerican.com/article/przewalskis-horses-are-finally-returning-to-their-natural-habitat/" target="_blank" rel="nofollow">Przewalski’s horse</a>, a wild relative and denizen of the steppe that has never been domesticated, at least in recorded history.</p><p>Next, when my colleagues and I reconsidered skeletal features linked to horse riding at Botai, we saw that&nbsp;<a href="https://doi.org/10.1038/s41598-021-86832-9" target="_blank" rel="nofollow">similar issues are also visible in ice age wild horses</a>&nbsp;from North America, which had certainly never been ridden. Even though horse riding can cause recognizable changes to the teeth and bones of the jaw, we argued that the small issues seen on Botai horses can reasonably be linked to natural variation or life history.</p><p>This finding reopened the question: Was there horse transport at Botai at all?</p><p><strong>Leaving the Kurgan hypothesis in the past</strong></p><p>Over the past few years, trying to make sense of the archaeological record around horse domestication has become an ever more contradictory affair.</p><div class="feature-layout-callout feature-layout-callout-xlarge"> <div class="ucb-callout-content"><div class="image-caption image-caption-"><p> </p><div class="imageMediaStyle medium_750px_50_display_size_"> <img loading="lazy" src="/asmagazine/sites/default/files/styles/medium_750px_50_display_size_/public/article-image/botai_horsemen.jpg?itok=7yRxxAmC" width="750" height="474" alt="Re-enactment of Botai horsemen"> </div> <p>A re-enactment of Botai hunter-herders (Photo: <a href="https://handfuloffilms.ca/about/niobe-thompson/" target="_blank" rel="nofollow">Niobe Thompson</a>)</p></div></div> </div><p>For example, in 2023, archaeologists noted that human hip and leg skeletal problems found in Yamnaya and early eastern European burials looked a lot like problems found in mounted riders, consistent with the Kurgan hypothesis. But problems like these can be caused by other kinds of animal transport, including the&nbsp;<a href="https://doi.org/10.1016/j.jchb.2017.05.004" target="_blank" rel="nofollow">cattle carts found in Yamnaya-era sites</a>.</p><p>So how should archaeologists make sense of these conflicting signals?</p><p>A clearer picture may be closer than we think. A detailed genomic study of early Eurasian horses, published in&nbsp;<a href="https://doi.org/10.1038/s41586-024-07597-5" target="_blank" rel="nofollow">June 2024 in the journal <em>Nature</em></a>, shows that Yamnaya horses were not ancestors of the first domestic horses, known as the DOM2 lineage. And Yamnaya horses showed no genetic evidence of close control over reproduction, such as changes linked with inbreeding.</p><p>Instead, the first DOM2 horses appear just before 2000 BCE, long after the Yamnaya migrations and just before the first burials of horses and chariots also show up in the archaeological record.</p><p>For now, all lines of evidence seem to converge on the idea that horse domestication probably did take place in the Black Sea steppes, but much later than the Kurgan hypothesis requires. Instead, human control of horses took off just prior to the explosive spread of horses and chariots across Eurasia during the early second millennium BCE.</p><p>There’s still more to be settled, of course. In the latest study, the authors point to some funny patterns in the Botai data, especially fluctuations in genetic estimates for generation time – essentially, how long it takes on average for a population of animals to produce offspring. Might these suggest that Botai people still raised those wild Przewalski’s horses in captivity, but only for meat, without a role in transportation? Perhaps. Future research will let us know for sure.</p><p>Either way, out of these conflicting signals, one consideration has become clear: The earliest chapters of the human-horse story are ready for a retelling.</p><hr><p><em><a href="/anthropology/william-taylor" target="_blank" rel="nofollow">William Taylor</a> is an assistant professor of anthropology</em><em>&nbsp;in the&nbsp;<a href="/anthropology/" target="_blank" rel="nofollow">Department of Anthropology</a>&nbsp;at the&nbsp;<a href="https://theconversation.com/institutions/university-of-colorado-boulder-733" target="_blank" rel="nofollow">91</a>.</em></p><p><em>This article is republished from&nbsp;<a href="https://theconversation.com/" target="_blank" rel="nofollow">The Conversation</a>&nbsp;under a Creative Commons license.

Buchdahl has an Ashkenazi Jewish father, meaning that his ancestors came from Central or Eastern Europe, and a Korean Buddhist mother.</p><p>Raised in a synagogue that her Jewish grandparents helped to found, Buchdahl has written and spoken publicly about the pain that she experienced as a teen and young adult when she was the only Asian person in Jewish spaces. At other times, she was not recognized as Jewish – for instance, by the&nbsp;<a href="https://www.youtube.com/watch?v=FNhG8aW6gbI" target="_blank" rel="nofollow">Chabad rabbis on her undergraduate campus</a>.</p><p>She has also talked about moments when her family blended their heritages. During Passover, for example, the traditional plate for the Seder meal includes “maror”: bitter herbs to remind Jews of the pain of slavery. Many families use horseradish, but one year,&nbsp;<a href="https://www.facinghistory.org/resource-library/kimchee-seder-plate" target="_blank" rel="nofollow">Buchdahl’s mother swapped in kimchee</a>.</p><p>When the rabbi appeared on the PBS program “<a href="https://www.pbs.org/weta/finding-your-roots/about/meet-our-guests/angela-buchdahl" target="_blank" rel="nofollow">Finding Your Roots</a>,” she talked about the resonances that she sees between Jewish and Korean Buddhist culture, such as respect for elders and education.</p><p>It is this type of experience – growing up the child of an interfaith, interracial marriage – that sociologists&nbsp;<a href="https://www.whitman.edu/academics/majors-and-programs/sociology/faculty/helen-kim" target="_blank" rel="nofollow">Helen Kim</a>&nbsp;and&nbsp;<a href="https://www.whitman.edu/career-prep/career-and-community-engagement-center/our-staff/noah-leavitt" target="_blank" rel="nofollow">Noah Leavitt</a>&nbsp;focus on in their 2016 book “<a href="https://www.nebraskapress.unl.edu/nebraska/9780803285651/" target="_blank" rel="nofollow">JewAsian</a>,” the first major study of Asian American Jews.</p><p><strong>‘You’re Jewish?’</strong></p><p>Other Asian American Jews were adopted into Jewish families, most of whom are white and Ashkenazi – an experience studied by&nbsp;<a href="https://adoptionandjewishidentity.org/" target="_blank" rel="nofollow">the Adoption and Jewish Identity Project</a>.

In fact, in my hometown when I was growing up, they were at the same time and in the same place, such that there was a Hebrew School-Chinese School car pool – but also such that no one could participate fully in both programs.</p><p>In addition, Asian Jewish adoptees and other Jews of color face assumptions from many white Jews that Jews of color&nbsp;<a href="https://www.timesofisrael.com/new-major-study-on-jews-of-color-highlights-experiences-of-discrimination/" target="_blank" rel="nofollow">are not Jewish</a>&nbsp;or are converts. Usually, children adopted into Jewish families do undergo a formal conversion. They grow up in Jewish homes, as familiar – or not – with Jewish traditions as people born into Judaism.</p><p><strong>Converting to Judaism</strong></p><p>Some Asian American Jews are adult converts to Judaism, like SooJi Min-Maranda, the Korean American executive director of&nbsp;<a href="https://aleph.org/" target="_blank" rel="nofollow">Aleph: the Alliance for Jewish Renewal</a>, a movement that trains and ordains Jewish leaders from a range of Jewish backgrounds. So am I, a half-South Asian&nbsp;<a href="/jewishstudies/samira-mehta-0" target="_blank" rel="nofollow">scholar of American Jewish religious history</a>.</p><p>I usually do not look for ways to combine my Indian heritage and my Jewish religious life, but every now and then I find myself doing so – as at Hanukkah, when I have&nbsp;<a href="https://theconversation.com/untraditional-hanukkah-celebrations-are-often-full-of-traditions-for-jews-of-color-191318" target="_blank" rel="nofollow">celebrated with deep-fried Indian food</a>, and&nbsp;<a href="https://theconversation.com/on-sukkot-the-jewish-festival-of-booths-each-sukkah-is-as-unique-as-the-person-who-builds-it-213201" target="_blank" rel="nofollow">during the festival of Sukkot</a>, when I have imagined making the holiday’s signature booths out of Indian bedspreads.</p><p>As with all people who choose to live Jewish lives, Asian Americans convert to Judaism for many reasons. After conversion, we often find ourselves fending off the assumption that either we are not Jewish or that our conversions were motivated exclusively by marriage.</p><p>In fact, there are enough Asian American Jews out there that several organizations serve them. For instance, the&nbsp;<a href="https://www.weareasianjews.org/about" target="_blank" rel="nofollow">Lunar Collective</a>&nbsp;“cultivates connection, belonging and visibility for Asian American Jews.” They host Seders and Friday night Shabbat events for Asian American Jews, along with a range of other programming. Other organizations, such as&nbsp;<a href="https://mitsuicollective.org/" target="_blank" rel="nofollow">the Mitsui Collective</a>, founded by Chinese American Jewish activist Yoshi Silverstein, address a broader range of the Jewish community but carefully include and make space for Asian Jewish experiences.</p><p>Asian American, Native Hawaiian and Pacific Islander Heritage Month and Jewish American Heritage Month come every May. They offer us a moment to remember that both of those communities are far more diverse than one might initially imagine, that they overlap, and that in their overlap, there is truly amazing diversity.</p><hr><p><em><a href="/jewishstudies/samira-mehta-0" target="_blank" rel="nofollow">Samira Mehta</a> is director of the <a href="/jewishstudies/" target="_blank" rel="nofollow">Program in Jewish Studies</a> and an assistant professor of&nbsp;<a href="/wgst/" target="_blank" rel="nofollow">women and gender studies</a>&nbsp;at the&nbsp;<a href="https://theconversation.com/institutions/university-of-colorado-boulder-733" target="_blank" rel="nofollow">91</a>.</em></p><p><em>This article is republished from&nbsp;<a href="https://theconversation.com/" target="_blank" rel="nofollow">The Conversation</a>&nbsp;under a Creative Commons license.
