Cultured Meat: An Ethical AlternativeTo Industrial Animal Farming

Policy paper

Industrial livestock production presents a growing problem on a global scale in terms of

animal welfare, environmental sustainability, and human health. One solution might be

cultured meat, in which animal tissue is grown in a controlled environment using cell cul-

ture technology, thereby making the raising and killing of animals for food unnecessary.

This approach shows great potential of meeting all the requirements of a humane, sustain-

able and healthy form of meat production. However, a great deal of scientific, technical,

cultural and legislative challenges must be overcome before cultured meat can reach cost-

competitiveness. Lack of funding is the main barrier to further development, and consid-

erable upfront investment is needed for cultured meat to attain commercially viable retail

prices. We therefore strongly support increased funding of cultured meat initiatives. This

entails, in order of priority: research and development of technology suitable for mass pro-

duction, promoting fact-based public discussion regarding the technology and its societal

implications, and eventual marketing of end products to consumers.

Cultured Meat: An Ethical Alternative To Industrial Animal Farming

Introduction

Each year, more than �� billion sentient animals � arereared in industrial conditions in order to produce meat.This global enterprise is currently the planet’smain sourceof human pandemic diseases�–� and likely among itsgreatest concentrations of human-inflicted su�ering.�–�

Curbing this ongoing moral catastrophe should thus be ofhigh concern for people aiming to e�ectively help asmanysentientbeingsaspossible.�,�–��Moreover, animal agricul-ture contributes to climate change and makes ine�icientuse of a significant portion of our available resources. ��

Addressing this massive challenge would ideally in-volve a worldwide shi� to a vegetarian lifestyle, but sucha shi� is unlikely to take place in our lifetimes. Humansaround the world namely place a high value on meat interms of taste, nutrition, and tradition, evidenced in partby a clear rise in global meat consumption over the pasthalf century—a trend strongly associated with economicgrowth in newly industrializing countries. ��–�� Despite thevegetarian movement having witnessed steady growth inrecent years, its growth pales in comparison to the globaldemand for meat, which is predicted to increase by ��%within ����. �� Meanwhile, plant-based meat substitutesmay, despite decades of costly improvements, not be suf-ficiently e�ective at replacing meat in people’s diets. �� Itwould thus be a significant gain if we were able to intro-duce a cruelty-free replacement for meat with the abilityto rival conventional livestock-production.

Enter cultured meat, an innovative way of synthesiz-ing meat from animal tissue samples. Compared withconventionalmethods ofmeat production—which involvethe breeding, raising, feeding, and slaughter of livinganimals—culturedmeat instead involves using a cell sam-ple to grow desired tissue in a controlled environment,making use of biotechnology originally developed formedical research and organ transplants. Proponents ofcultured meat argue that this technology holds consid-erable promise as a replacement for conventional meat.Indeed, cultured meat seems likely to o�er vast benefitsin terms of animal welfare, ��,�� environmental impact��–��

and human health.

The concept of producing meat intended for humanconsumption independent of a complete living organismhas been a subject of speculative interest since at least����,�� but proof of concept has existed in various formsonly since the early ����’s.�� Culturedmeat technology isstill in its experimental stage and has so far been limited toproducing a small number of processedmeat items in lab-oratory settings for demonstrative purposes.��,�� Currentresearch is focused on refining production methods in or-der to lower cost, improve scalability andminimizedepen-dence on animal sources.

In this paper, we begin by presenting the rationale be-hind developing animal-free meat products. Moving on,we explore cultured meat and its ethical, economic, envi-ronmental, and human health implications. We then re-view the most pressing challenges facing public accep-tance and technical feasibility of cultured meat produc-tion, and conclude by proposing a number of funding rec-ommendations.

Current impacts of livestock-basedmeat

Environmental

Greenhouse gas emissions: The main causes of climatechange are usually attributed to transportation andhousing. This, however, ignores another significantcontributor: according to the UN Food and Agri-culture Organization (FAO), animal agriculture is re-sponsible for ��.�% of the world’s total greenhousegas (GHG) emissions.�� It is therefore as bad for theenvironment as the combined impact of every mo-tor vehicle in the world, which collectively repre-sent at ��%.�� Methane, whose global warming po-tential is �� times greater than that of carbon diox-ide,�� makes up ��% of the animal industry’s totalemissions. Most of this methane is emitted by ru-minants such as cows, sheep and goats as a naturalby-product of their digestive processes. The UnitedNations Environment Programme (UNEP)maintainsthat a reduction of greenhouse gas emissions of at

Cultured Meat: An Ethical Alternative To Industrial Animal Farming

least ��%by ���� is necessary in order to avoid theworst impacts of climate change.��

Resource ine�iciency: The global surface area requiredfor livestock farming—including land used for graz-ing and feed production—currently takes up around��% of all arable land on the planet, and ��% of itstotal ice-free land surface.� The rate at which live-stock animals convert feed to energy and protein,meanwhile, is extremely ine�icient; cows, for exam-ple, normally convert less than �% of their proteinand energy intake into ediblemeat. �� Taking into ac-count the water consumption for production, morethan ��,���L ofwater are needed for �kg of beef.��,��

Water pollution: The livestock sector uses a great deal ofwater for feed production, animal rearing, and sani-tation. Water recycled from livestock manure is cur-rently responsible for around ��%of global nitrogenand phosphorous pollution, ��% of antibiotic pol-lution, and ��% of toxic heavy metals contaminat-ing theworld’s freshwater. Additionally, around��%of pesticides that end up in global freshwater sup-plies have their origin in the production of animalfodder.�

Human health

Infectious disease transmission: Livestock pose a signif-icant disease risk to humans. Around ��% ofall known human diseases and ��% of the mostdamaging emerging diseases are zoonotic (animal-transmitted) in origin.�,� Most pathogens of recentconcern—including mad cow disease (called newvariantCreutzfeldt–Jakobdisease in humans) andallforms of influenza (swine, avian, etc.)—are transmit-ted through livestock in particular.�,� Increases inglobal demand for animal products have already ledto intensification of industrial livestock farming,�,��

and this trend is expected to magnify as millions ofhouseholds are li�ed out of poverty in developingcountries. �� This has greatly increased overall riskof zoonotic disease transmission between livestockand humans.�,��

Antibiotic resistance: In animal agriculture, antibioticsare widely used in sub-therapeutic doses in orderto promote animal tissue growth, and as a low-cost preventative bio-security measure intended tocopewith the aforementioned disease transmissionproblem. However, this practice – which has re-sulted in substantial antibiotic contaminationofwa-

terways�� – is now considered a leading cause of theglobal rise of antimicrobial-resistant (multiresistant)pathogen strains.��–�� The World Health Organiza-tion considers this one of today’s biggest threats toglobal health.��,��,��

Animal welfare

Non-human sentience: There is a scientific consensus re-garding animal sentience and their capacity to suf-fer�� and this is o�icially recognized in EU legisla-tion.�� The opposing view that conscious experi-ence is only possible in human brains is not sup-ported by current evidence.��,�� It follows that anyneedless su�ering inflicted upon animals under hu-man care, whether through direct action or inac-tion/neglect, is ethically unacceptable and must bestopped.

Su�ering in factory farms: Intensiveanimal farming is in-escapably associated with systematic disregard fortheir welfare.��–�� Animal farming is already veryine�icient in terms of land and sustenance re-sources,��,�� andhighmarket demand formeat thusresults in farmers striving tomake all aspects of pro-duction more cost-e�ective. Maintaining the well-being of animals is o�en time-consuming, yet notstrictly necessary to produce meat at an a�ord-able level. The result is that animal welfare mea-sures are commonly reduced to an absolute mini-mum or largely ignored in factory farms.�,��–��,��–��

An example of this e�ect is the “broiler chicken”,a chicken breed optimized for morbid obesity andrapid maturation. Kept in intensive farming con-ditions throughout the industrialized world, thesebirds frequently experience lifelong su�ering��,��

from their legs collapsing under their own morbidweight ��,�� and from chronic sickness due to poorlyventilated, overcrowded and/or tightly confined liv-ing conditions.��

Poor legal protection: Despite U.N. and EU guidelines toensure animal welfare,��,�� actual legislation ona national level is o�en weak and/or poorly en-forced.��,��Moreover, established laws are routinelydisregarded by manufacturers;�� in Europe alone,at least ��% of piglets are routinely subjected topainful mutilations like tail amputations and castra-tion— both without anesthesia.��,�� This ignores EUdirectives requiring that member states “... shall,since animals are sentient beings, pay full regard

Cultured Meat: An Ethical Alternative To Industrial Animal Farming

to the welfare requirements of animals”, includingtheir freedom from pain, injury, discomfort and dis-tress.�� It is not uncommon for largemeatproducersto resist public inspection of their farms and slaugh-terhouses, and part of what is currently knownabout animal abuse in the meat industry is thus aresult of investigations by animal charities, both un-dercover��,�� and in cooperation with farming con-tractors.��

Culturedmeat in comparison

Environmental impact

Predictive environmental analyses: Assessing the re-source e�iciency of industrial processes that don’tyet exist involves making many informed assump-tions, many of which will later turn out incorrect.Life cycle analyses have so far predicted that cul-tured meat would require ��% lower land use and�� – ��% lowerwater use than its animal agricultureequivalents.�� Subsequent analyses haveplaced en-ergy use predictions much higher due to the largeamounts of electrical energy that would be neededto provide su�icient heat to the culturing process.��

Overall, however, cultured meat is expected to besignificantly more resource e�icient than animalagriculture, especially when predictions of futuremeat consumption are taken into account.��

Environmental pollution: The aforementioned life cycleanalyses predict that cultured meat would produce�� – ��% less greenhouse gas (GHG) emissions thanconventionalmeat.�� Replacing all meat productionwith cultured meat could reduce EU emissions bytwo orders of magnitude.�� Excluding animals frommeat production would also eliminate the needfor manure disposal and management, which cur-rently involves the use of manure lagoons.�� Cul-tured meat would replace these highly problem-atic sources of pollutionwith closelymonitored andquality-controlled filtration systems.�� Again, theseare speculative figures and should be regarded assuch.

Human health

Sterile production: Due to the aseptic and strictly con-trolledenvironment required for itsproduction, pro-ducing meat from cell cultures is safer than con-ventional production through animal husbandry.��

Conventional risks of zoonotic infection are by-passed when no live animals are directly involvedin production.��–�� Theonly current producer of cul-tured meat reports that antibiotics are not requiredduring production.�� In line with current medicalstandards, initial tissue samples from biopsies re-quire screening for infectious agents before even-tual use in culturedmeat production. The end prod-uct is thus saferduring storage, preparationandcon-sumption than its conventional counterparts.

Composition of end product: Another benefit of strictmanufacturing control is that it allows for significantmodification of the final product during production(as opposed to relying mainly on post-productionprocessing) at levels currently unattainable in con-ventional meat production.�� A wide range of alter-ations to the final product’s nutritional composition,taste, and texture is thus made available by e.g. co-culturing with other cell types or introducing addi-tives during the culturing process.�� Geneticmodifi-cation�� can be used for the same purpose, but runsthe risk of rejection by consumers due to public con-cern over safety.

Commercial

Product safety: The fact that it is virtually impossible togrow culturedmeat outside of a sterile environmentcould make it a preferred alternative for many con-sumers who are worried about food safety.�� In par-ticular, the roughly ��% of European consumerswho are worried about biological risks (contamina-tion from antibiotics and zoonotic diseases) mayprefer culturedmeat over other options.�� However,the same surveys also showed technological risks(chemical additives and cloning) as being of higherconcernamongconsumers thanbiological risks. It istherefore uncertain whether promoting food safetywill benefit cultured meat acceptance among con-sumers.

Innovative product attributes: Strict control over themanufacturing process would allow for products tobe nutritionally fortified��,��,��,��,�� and contain lessunhealthy fat.�� Thismay present an opportunity tomeet consumerdemand for healthier foods�� and tohelp prevent undernourishment in poorer popula-tions. Producers could also experiment with a rangeof characteristics that consumers would find inter-esting, such as novel flavors, colors and textures.��

�

Cultured Meat: An Ethical Alternative To Industrial Animal Farming

Culturing also allows for the production of exotic orotherwise rare animal meats��,�� which, in additionto being of potential commercial interest, may re-place much of the legal�� and illegal�� markets forexotic animals.

Improved ethical profile: European consumers expressan increasing concern over the impacts ofmeat pro-duction on food safety, the environment, and ani-malwelfare.��,��,��–�� There is someevidenceof con-sumers being willing to pay extra for safety-labelledproducts due to this concern, particularly regardingproducts fromwell-knownbrands.�� In recent years,animal welfare in particular is identified as a decid-ing factor for consumers in evaluating the ethicalprofile of brands, with cost being the main barrierto buying more products regarded as ethical in thisregard.��–�� Thus, already-establishedmeatproduc-ers may find a chance to improve public perceptionof their brand, in terms of food safety and animalwelfare, by adopting cultured meat technology.��

Indeed, at leastone leading internationalbrand isal-ready considering this opportunity.��

Market expansion potential: In the event that culturedmeat overtakes normal production methods interms of production cost-e�ectiveness, we shouldalso expect a proportional decrease in the mar-ket value of meat products, opening up for signifi-cantly lower retail prices on meat products.�� Thispresents apotentialwin-win: more low-incomecon-sumers would be able to a�ord meat products witha higher nutritional and caloric density than manystaple foods currentlyprovide, andproducerswouldin turn benefit from the increased revenue followingexpansion into this huge new target market.

Animal welfare

No need for slaughter: Perhaps cultured meat’s greatestpotential benefit over conventional production isthe fact that it does not rely on slaughtering animalsat any point in the manufacturing process. Each ofthe individual parent cells involved in culturedmeatproduction canmultiply a vast number of times, andeach donor animal possesses billions of such cells intheir body. The number of animals required for tis-sue samples are thus orders of magnitude less thanfor conventional meat production. Depending onthe method and type of cell used, a single “parentcell” could theoretically supply the annual global

demand for meat products before needing replace-ment.�� However, natural variations in characteris-tics between cell samples (i.e. those extracted fromliving animals) renders them impractical for use inearly phases of basic research. It is therefore morelikely that genetically modified cell lines would beused during the initial research phase, as these cellsare more homogeneous between batches. Theywould not, however, be necessary for use in actualfood production. Even so, a genetically altered cellline could be made physically immortal, meaningthat a single tissue sample from one livestock ani-mal would theoretically be enough to meet endlessfuture demand.

Minimal harm: Cells can be collected by drawing a smallamount of stem cells from an animal using a biopsyneedle, a typeof syringe. This commonmedical pro-cedure takes only a few minutes, can be performedunder local or full anaesthesia, and poses little riskof long-term complications�� — altogether causingnegligible harm compared to what animals in themeat industry are normally forced to endure on alifelong basis.

Concerns over culture medium: "Feeding" nutrients tocell cultures is achieved by means of a culturemedium, a sterile liquid containing essential macro-nutrients (sugars, amino acids) and micro-nutrients(vitamins,minerals) for the growing cells. At themo-ment, foetal bovine serum (FBS) is a key compo-nentof the standardculturemediumused inbiotechlabs all over the world. Since obtaining this ingredi-ent requires slaughtering a pregnant cow and drain-ing blood from the heart of its live, un-anesthezisedfetus—a decidedly inhumane process��—it has sofar posed a major problem for the ethical profile ofcultured meat. Its use in biomedical tissue engi-neering so far, however, has largely been a resultof its abundance as a by-product of animal agricul-ture, and it would simply not be practically feasi-ble to use it for mass production of cultured meateven if one wanted to. Ideal culture media should,in any case, be completely freeof animal-sourced in-gredients, and prototypes of FBS-free culturemediabased on plants, fungi and microalgae have alreadybeen demonstrated.��,��–�� Microalgae productionhas also been accounted for in speculative life cy-cle analyses of large-scale cultured meat produc-tion systems.��,��While further refinement isneeded

�

Cultured Meat: An Ethical Alternative To Industrial Animal Farming

for plant-based media to compete with the e�ec-tiveness of FBS, they nonetheless prove that ingre-dients sourced from slaughtered animals are not arequirement for cultured meat production. More-over, the fact that FBS is used in practically all theworld’s biotech labs in spite of its o�en heteroge-neous composition between batches (which o�enleads to inconsistent data if more than one batch isused in a given study) means that there is already astrong incentive in the biotech industry to develophighly consistent culture media which can bemass-produced from rawmaterials.��

Challenges to cultured meat develop-ment

Current status

Funding for basic research: Much of the basic biotech-nology research needed to mass produce culturedmeat has yet to be done, including studies on op-timal cell lines and culture media.�� As of Septem-ber ����, there exists only one specialized labora-tory devoted to developing culturedmeat, operatedby the non-profit New Harvest in Leiden, NL.�� Be-yond this, there are as yet no scientific disciplines,departments or institutes devoted entirely to the re-search and development of “biofabrication” or “cel-lular agriculture” as distinct areas of study.�� Mostresearch into cellular agriculture to date has thusbeen undertaken as isolated projects and have con-sequently not been met with widespread academicinterest. This point is illustrated by the fact thatall cultured animal products of recent fame (groundbeef, leather, milk, etc.) have been manufacturedin laboratory conditions, using costly techniquesadapted ad-hoc from related fields in biotechnologythat normally exist in relative isolation. Ongoing ini-tiatives with promising long-term strategies are cur-rently held back by a severe lack of funding.

Few researchers: Contrary to what is o�en portrayed innews media coverage, very little scientific attentionis being given to the research and development ofcellular agriculture—including cultured meat—as ofMarch ����. One expert estimate places the num-ber of entirely devoted researchers at about � indi-viduals worldwide, with another ��-��� known re-searchers in related fields expressing varying de-

grees of interest inworkingon cellular agriculture.��

Lack of regulatory preparedness: Although some Euro-peancountrieshavementionedculturedmeat in thecontext of novel foods,��–��� the relative infancy ofthe science behind itmeans that current food indus-try regulations are generally not prepared for com-mercial production at any significant scale.

Genetic modification: Genetic modification (GM) is notstrictly necessary at any point in the production ofcultured meat. It may, however, be needed duringinitial phases of research (see: Concerns over culturemedium), as well as potentially ensuring economicviability at somepoint in the future, and should thusnot be ruled out as a potential tool.�� Any use of GMin the production of culturedmeat should necessar-ily involve rigorous transparency and openness topublic inquiry to alleviate any concerns related tothe safety of GM foods.

Product mimicry: Twoculturedmeatproductshavebeenpublicly demonstrated so far: one hamburger ���

and one meatball. ��� Both were made from beefcells; however, the team behind the meatball arealso developing pork cells, ��� and another team inIsrael are working on avian cells from chickens. ���

The twobeefproductsweredescribedasunambigu-ously meat-like in taste, yet lacking in certain qual-ities like moisture and fat. The teams behind eachdemonstration report that existing technology canbe used to improve taste, texture and nutritionalcomposition.��,�� Di�iculties in replicating complextextures such as steak, chicken breast, and baconhave so far limited textures to that of mince meat.Significant improvements are needed to overcomethese di�iculties, yet only one study is going on atthe moment. ��� Improving ground beef products tothe point ofmarket-competitive texture ismuch lesschallenging and therefore remains the primary fo-cus for now.��,�� This approach seems most likelyto secure cultured meat a place among popularmeatproducts on store shelves,whichwill be crucialin gaining acceptance for all subsequent culturedproducts as soon as they are introduced.

Culture medium: Althoughprototypesof animal-free cul-ture media exist and have been used to producemuscle tissue,��,��,��,��,�� progress in this area isseverely hindered by the fact that optimal cell lineshave not yet been found, as individual cell lines of-ten require distinct medium formulations to prolif-

erate.��,��� Biomass frommicroalgae seems the pre-ferred source for the nutrients needed in culturemedia; however algae production at scales largeenough to meet the requirements of cultured meatposes a number of technical challenges, many ofwhich (including the scaling up of bioreactors) arecurrentlybeing tackled forapplications in seeminglyunrelated fields such as biofuels ���,��� and animalfeed. ���

Energy requirements: One recent life cycle analysis (LCA)of cultured meat production found that, while landand water use are expected to be far lower than allother forms of meat production, its energy require-ments would be extremely high compared with pre-vious estimates.�� However, the analysis extrapo-lated data based on assumptions of technology thatdoes not yet exist and contradicts previous findings,making it far from conclusive. ��� Whether or not theenergy requirements present a problemdepends onthe e�iciency of renewable energy sources, whichmay improve in the future thanks to rapid develop-ments in solar power and other renewable energysources.��,���,���

Cost: The only private company making cultured beef asof June ���� reports a production cost of about€��,���/kg,�� representing an ��-fold price reduc-tion compared with the €���,���/kg burger un-veiled in ����. One leading researcher announcedin late ���� that, under ideal conditions, combin-ing pharmaceutical bioreactor technology to exist-ing tissue culture techniques can already reducecosts to €��/kg of cultured ground beef.�� It shouldbenoted that,while thecostof culturedmeat shouldaim to match that of regular meat, the current mar-ket average of meat ��� is artificially low as a resultof heavy government subsidizing of animal agricul-ture.

Public perception

Media coverage: News media have generally presentedcultured meat in a positive light, and have tendedto highlight its environmental benefits. ��� The sum-mer of ����witnessed three highly publicized, inde-pendent promotion events: in June, a TED talk onculturedmeat and leather; ��� in August, a public en-dorsementand$���,��� fundingannouncementbyGoogle co-founderSergeyBrin, ��� followedbya tele-vised broadcast of the first public tasting of cultured

meat. ��� Cultured meat has since been presentedat the World Economic Forum in ����,��,�� and aUS-based cultured meat start-up was launched inearly ���� to widespread interest from news and so-cialmedia alike. ��� However, news stories o�en por-tray incorrect stages of development, giving unreal-istic impressions of the extent of progresswithin thefield.�� An Israel-based cultured meat start-up waslaunched in April ����, ��� and as of September, ithad managed to raise double its initial crowdfund-ing goal of $���,���. ���

Consumer attitudes: A small-scale survey of Dutch con-sumers found that, when asked if they were will-ing to try cultured meat once it becomes available,being given information about its environmentalbenefits caused positive responses to increase from��% to ��%, a near-doubling compared with ba-sic informing about the technology itself. ��� Recentonline polls conducted on social and news mediasites have shown that � out of every �� respondentswould like to try cultured meat once it becomesavailable. ���–��� E�orts are being made to re-brandculturedmeat as "cleanmeat" inorder tobetter con-vey important qualities of cultured products, espe-cially its prospective environmental impact and lackof animal pathogens and drug residues. ���

Common objections to culturedmeat

“Cultured meat is unnatural, and therefore un-healthy/dangerous/undesirable.”

This argument rests on the assumption that what isnatural is good, and what is unnatural is bad. However,examples such as natural disasters and surgery show thatthis equalization is dubious: Something can be naturaland bad, or unnatural and good. Thus, calling culturedmeat "unnatural" does not imply that it is undesirable.Also, it is unclear why culturedmeat in particular is unnat-ural, but animal agriculture is not. There is currently verylittle resemblance between nature and industrial meatproduction in terms of how animals are bred, housed, fed,and slaughtered. Arguments of this kind may thus be bet-ter understood as critiques against inherent qualities ofindustrialization itself, rather than any of its specific uses.Althoughculturedmeatmaybe“artificially”produced, theend result is just as “real” as conventionalmeat, andposesno greater health risk; on the contrary, since it is manufac-tured in a controlled environment, cultured meat is farless likely to contain any of the the food-borne pathogens,

�

Cultured Meat: An Ethical Alternative To Industrial Animal Farming

pharmaceutical residues, and/or unhealthy fats of "regu-lar" meat.

“Culturedmeat representsnoethicalprogressas longas fetal bovine serum is used.”

This is correct; only cultured meat that is producedwithout the use of animal-derived culture media is eth-ically acceptable. Scientists working in the field of bio-fabrication agree that FBS has no place in the future ofcultured meat.�� Its use so far is a result of its abundanceas a by-product of livestock production, and the fact thatits applications in biomedicine have been several ordersof magnitude smaller than what will be needed for cul-tured meat. We consider the development of animal-freeculturemedia a necessity for culturedmeat development,and we strongly promote all e�orts to achieve this goal.

“Although cultured meat may be a short-term solu-tion, it doesnot changeunderlyingattitudes towards an-imals or the environment, and is therefore bad in thelong term.”

It is indeed important to address underlying speciesistattitudes, as this determines how nonhuman animals willbe treated in the future. However, the development of cul-turedmeatdoes in fact indirectly contribute to a long-termchange in social normsandattitudes. Thebehavioural factof meat eating is an obstacle to unbiasedmoral reasoningthat cultured meat could greatly reduce. By eliminatingthe need to defend everyday behaviour, cultured meatmakes it psychologically easier to care about nonhumananimals both on an individual and on a political level.Thus, cultured meat could facilitate the transition fromtoday’s heavily speciesist society to a more antispeciesistone in the future. In general, however, any ideal solutionwould need to combine attitude- and behavior-improvingapproaches with technological ones in order to ensurelasting change.

“There is no need to develop cultured meat whenplant-basedmeat alternatives already exist."

Significant progress is indeed being made in the fieldof plant-basedmeat alternatives, andmany suchproductsare rising in popularity in theWest. However, this is not thecase in countries such as China, where the traditional useof plant-based protein sources are rapidly being replacedby meat, particularly from pigs and chickens. ��,���,���

Conclusions

It appears that, by gradually replacing animal agriculture,large-scale production of cultured meat could greatly re-duce animal su�ering, human disease risk, and environ-mental problems. Achieving this will nevertheless be anextremely di�icult, costly and time-consuming challenge,requiring several years’ worth of concerted e�ort acrossmultiple disciplines before cultured meat can rival con-ventional meat products. However, cultured meat re-search has received very little attention so far, makingit relatively easy to conduct basic research that may laterprove catalytic to further development. This, in combi-nation with its potentially extraordinary return on animaland human welfare in the long term, convinces us thataccelerating cultured meat is a worthwhile investment atthis time.

We therefore strongly support e�orts to:

�. Fund and promote academic interest in cellularagriculture

Due to its high uncertainty, pioneer-ing science should ideally take placewithin the low-risk research climate ofacademia, with funding provided by gov-ernments and non-profits to ensure thatfindings become publicly available. Thiswill enable widespread adoption and re-finement of techniques across scientificdisciplines worldwide. It is our under-standing that, at this time, the followingresearch focuspoints are of particular im-portance: optimal cell lines, plant-basedculture media, scaling-up of bioreactors,and perfusion systems for growing com-plex muscle tissue.

�. Increase public awareness about the benefits ofculturedmeat

Once a solid research foundation exists,entrepreneurs will be able to experimentwith scaling and marketing of culturedproducts to consumers. It is possible thatthe ensuing market could expand rapidlyif significant public interest in cellularagriculture already exists by this time.

�

Cultured Meat: An Ethical Alternative To Industrial Animal Farming

�. Facilitate culturedmeatdevelopment throughpol-icy changes

It is possible that government subsidiesand increased national budgets for bio-and agrotechnology research can accel-erate the development of cultured prod-

ucts. Once economically viable, cellularagriculture will also require new regula-tory frameworks in each country whereproduction is to take place. Early involve-ment from political organizations mayease the intricate political work that isneeded in both cases.

Sentience Politics is an anti-speciesist political think-tank. We advocate a society which grants moral

consideration to all sentient beings, regardless of their species membership. Our activities include

political initiatives and the composition of scientific position papers, in order to encourage rational

discussion on important issues.

Our philosophy is based on e�ective altruism: How can we use our limited resources (time and

money) to reduce as much su�ering as possible? Sentience Politics uses rationality and empirical

science in order to identify and implement the most e�ective strategies. We also use this approach in

order to select and prioritize the causes that we work on.

Sentience Politics was founded as a project of the E�ective Altruism Foundation (EAF) in ����. EAF is

an independent think tank and project overseer founded at the intersection of science and ethics by

a team of young, interdisciplinary individuals. It is a part of the fast-growing E�ective Altruism

movement, and aims to improve the lives of as many sentient beings as extensively as possible. In

order to achieve this goal with limited resources, EAF uses rational thinking and evidence-based

approaches.
