Livestock provide food, income, education, cultural status…and hope.

African farmland

I took the photo above while travelling in South Africa last year. Whenever I’m faced with the inevitable “But we can just grow corn and soy to feed humans!” anti-livestock rhetoric (as seen in The Guardian this past week), I’m reminded of this picture. It shows tiny rural homes on the edge of a major road, upon which the majority of people walk to work, dodging the traffic as they go. The land is rocky, steep and lacks nutrients, the soil only capable of producing fibrous grasses that can’t be eaten by people. Yet, another few hundred yards down the road, we came across a goat.

African goat (straighter)

For many people in low-income countries, a goat is a lifeline. A source of food that improves the nutrition and health of young children, pregnant women and elderly people. A source of income to allow children to attend school and have a future career, rather than working to support their family before the age of 10. A source of security that allows for improved mental health, female independence and cultural status. Last week I spoke at a Cheltenham Science Festival panel entitled “Should we all become vegan?” It’s easy to suggest that many of us in the developed world could eat less meat. However, the myriad benefits provided by livestock to people in low-income regions should not be foregone on the grounds of foodie ideology bestowed by those of us living in developed regions.

I’m pleased to see Prue Leith, Jenny Eclair, Bob Geldof, Jonathan Dimbleby and others lending their support to Send a Cow’s #UnheardVoices campaign. Let’s recognise livestock’s role in giving hope to those who need it most – and make those voices heard.

One vegan does not a movement make – less than 3,000 omnivores confirmed to have been “converted” by #Veganuary

Burger grass-fed.jpg

Would a cheeseburger have tempted you away from #Veganuary?

Well, the official numbers have been published for #Veganuary, the 2018 attempt to entice people away from meat and towards the heady delights of almond juice and bean curd. The campaign has been cited as a magnificent success by such impartial publications as Plant Based News (has that been the guest publication on Have I Got News for You yet?) with 62% of survey respondents (who were not previously vegan) stating that they intend to continue with a vegan lifestyle.

On the face of it, that does sound impressive, admittedly slightly less so given that it means 38% of participants presumably thought “Sod that Veganuary lark, I’m off for a bacon sandwich with cheesy chips.”

Yet here’s the rub. Despite the claims of success, the survey was only sent to 50% of participants. That’s slightly odd given that, presumably, the majority signed up online with a valid email address. There was then a 14% response rate to the survey. That means that overall, only 7% of peoplea who undertook Veganuary actually completed the survey.

Let’s assume that those who replied and confirmed that they were going to continue a vegan lifestyle were a random sample of the Veganuary population. This is a bit of a stretch, as anybody who’d not enjoyed Veganuary and was happily chomping down on a bacon sandwich would be considerably less motivated to reply than somebody who thought it was the best thing since sliced tofu. The stretch is underlined by the fact that 99% of respondents would recommend Veganuary to others – so basically a sub-section of happy campers. However, we’ll give it benefit of the doubt.

40% of people who completed the survey had previously identified themselves as omnivores (compared to 16% pescatarian, 33% vegetarian and 11% vegan). If we extend that statistic out to all the people who undertook Veganuary (168,500 people), then 67,400 peopleb – just less than the population of Stafford in the West Midlands – were originally omnivores. So, if the assumptions made earlier hold true, 7% of those previously-known-as-omnivores replied to the survey (4,718 peoplec) and of those, 62% aimed to stay vegan.

So 2,925d omnivores have confirmed that they will remain vegan – are the rest enjoying a cheeseburger for lunch? Who knows. However, human nature being what it is, the “converted” number may be even smaller in a few months time.

Are vegan numbers increasing? Yes. Is it a massive trend? No. A fad prevalent in westernised society? Maybe. In 2016, 17.86 million babies were born in China. That’s 48,932 born per day, many of whom will choose to emulate the western diet. So, in just one day, 15.7-fold more babies are born in a country where meat and dairy consumption are predicted to increase over coming decades, than the number people who we know have actually pledged to stay vegan (having previously been omnivorous) after Veganuary. Was Veganuary a storm in a tea cup? Yes – with milk…and a cheese sandwich on the side.

Is your dinner more intelligent than a baby…and should you care?

Daisy the pig

If Daisy the pig can recognise herself in a mirror, does that mean she shouldn’t be turned into bacon?

In the wake of a seriously busy #Februdairy, where activist rhetoric was thrown around like confetti at a summer wedding (my personal favourite activist claim – milking cows just promotes patriarchal societies in which females are treated like objects…), this little gem just arrived in my Twitter messages.

It’s a interesting little animation, probably aimed at giving food for thought (groan…), with the premise that if the animals that we eat for dinner (pigs, octopi, etc) are more intelligent than something that we wouldn’t eat (a human infant*), then should we be thinking twice about eating them?

There’s just one fatal flaw in this analogy – most livestock species are precocial. That means that when they’re born, they can quickly get up, feed and, if necessary, run away from predators. Not surprisingly, that can be essential for herbivorous prey animals in the wild. Animals that are not precocial are altricial – young are relatively undeveloped and helpless when born and tend to be hidden away in nests until they’ve gained maturity (e.g. mice).

Humans fall between these two extremes – gestation length is relatively long compared to other mammals, which favours increased foetal development and a higher birthweight, but human infants have smaller brains (29% of adult size compared to 40-45% in African apes) and have extremely immature motor skills. A significant amount of brain growth and development therefore occurs between birth and adulthood. Can an infant take the top off a child-proof medicine container? No. Can an adult? Absolutely. Does that mean that human infants lack intelligence? Not in the slightest. They just haven’t formed all the necessary brain and motor connections yet.

To try and compare the “intelligence” of a human infant with a fully-grown pig, octopus or sheep and draw any meaningful conclusion about whether or not we should eat the “intelligent” animal is an utterly futile comparison. Not quite apples to oranges, but close – after all, even the smartest apple can’t recognise itself in a mirror – or can it?

*Note that infanticide and cannibalism is practiced by some primates.

 

How to Argue with Vegans – A Cut-Out-and-Keep Chart (new and improved!)

I will never criticise anybody for being vegan, vegetarian, pescetarian, flexitarian or any other diet. Always put popcorn on top of tomato soup (don’t knock it till you’ve tried it…) or fancy a pickled onion and herring cocktail for breakfast? No problem, we’re all entitled to choose the foods that suit our lifestyle.

Although I often promote dairy and meat production, I would never demand that somebody eat a steak or a cheese sandwich – it’s entirely their choice. Yet, with the rise of social media, a growing proportion of people feel entitled to criticise other’s diets, to the point where logic, science and civilised debate are lost in a rampant outpouring of emotive language and misinformation.

Having been engaged in countless online conversations with vegans, it appears that a handbook must exist, as the debate follows an identical pattern. The same inevitably tedious questions posed and claims made, often without any regard for the responses from the other side. In case you decide to argue with a vegan, I therefore present you with my updated handy flow-chart for how the conversation may go. Note that I do not intend to mock and I’m sure that there are many vegans who are both eloquent and well-informed, but, if you are vegan, perhaps consider whether you always rely on these rather asinine claims, without broadening your argument?

Screen Shot 2017-11-13 at 17.39.03For example, is suggesting that we shouldn’t drink milk past-weaning because other animals do not, either upheld by science (no, it’s not) or a sensible criticism? After all, humans also wear expensive anoraks, use iPads and write books on the intricacies of rugby – should we forgo these activities because they are exclusive to homo sapiens?

It’s absolutely true that some people cannot digest lactose. Furthermore, a proportion of the population have adverse reactions to gluten, some people have life-threatening allergies to strawberries, others break out in a rash after eating scallops. Does that mean that we should all remove these foods from our diets in somewhat misguided sympathy? No.

It should be obvious that using overly emotive language or suggesting that farmers are guilty of obscene acts with farm animals detracts from your message. Nobody takes Boris Johnson seriously when he makes outrageous claims or shows utter disregard for cultural and social norms – why should anybody embrace a lifestyle choice where the messaging suggests that eating cheese is equivalent to drinking breastmilk or implies that artificial insemination of cattle is morally, physically and emotionally equivalent to serious sexual assault in humans?

I don’t converse with vegans in order to try and change their opinions, but to show all the others who are listening in the background that it’s possible to have congenial, polite and scientific debate on these topics without resorting to insults, foul language or suggestions that the opponent should “get their fist out of a cow’s rectum”.

Screen Shot 2017-11-13 at 15.12.35

I stopped engaging in a recent Twitter conversation when a vegan posted a screenshot of my Twitter bio and claimed that, as a breast cancer survivor, I was foolish to consume a “hormone cocktail” (milk). I may be biased, but using cancer, still a life sentence for far too many, as a tool for trying to promote veganism, utterly lacks the human compassion that the same person claimed should be extended to farm animals.

Screen Shot 2017-11-13 at 14.45.04

Let’s get real. If artificial insemination, housing cattle, removing the calf from the cow and all the other practices that are apparently abhorrent to vegans were outlawed, would those opposed to meat and dairy production on the grounds of exploitation and slaughter be appeased? No.

So, here’s the challenge to angry vegans. Blow away the smoke, mirrors and pseudo-animal welfare outrage, and ask the real question: Are you prepared to let animals be killed in order to enjoy meat? If the answer is yes, then move on, there’s nothing for you to tweet about here.

From The Archers to Antibiotic Resistance – Has BBC Radio 4 Lost the Plot?

ResistanceAfter some excellent commentaries on future food production and Brexit on Farming Today last week, it seems that, not content with domestic violence, miscarriage and admitting women to the Ambridge cricket team (the horror of it!) on The Archers, BBC Radio 4 has dived into modern agricultural issues with a vengeance. However, their latest venture has all the balance and perspective of Nigel Farage faced with a chicken vindaloo and a team of migrant NHS workers.

Developed through the Wellcome Trust Experimental Stories Unit and written by Val McDermid, well-known for her crime novels, “Resistance” describes the impact of an outbreak of antibiotic-resistant swine erysipelas, which passes swiftly from contaminated sausages at a music festival to the general public exhibiting dreaded “purple spots” and collapsing at the supermarket checkout.

Alas, having listened to the first two episodes with more than a passing interest (after all, antibiotic resistance is a huge issue for our industry, both from an animal and human health perspective), it’s clear that an aluminium helmet and a “meat is murder” sign may be required listening accessories. The main protagonist is a slightly holier-than-thou vegetarian who was turned away from meat by the animal rights activists with whom she worked on a story and is currently scratching around to find freelance work after her editors became afraid of “real investigative journalism.”

Cue a cliched storyline, lined up in true pantomime fashion with neon signs alerting the listener to every plot development. The contaminated meat is traced back to a “factory” farm in an urban location, with pigs kept in “tiny pens with no room to lie down or turn around.” A specialist (non-local) vet throws antibiotics at the animals and a surly, secretive, Eastern-European-accented farm manager doesn’t seem keen on a journalist sniffing around.

The  racial stereotyping is unfortunate given how much UK agriculture relies on workers from Europe and beyond, and the farm portrayed as secretive, polluting water and soil, and utterly lacking transparency. By contrast, organic systems with “humanely-farmed” animals, and “well-scrubbed, rare breed pigs” are the dramatic ideal. Yet in real life, farm assurance schemes such as Red Tractor (which covers >80% of UK pork) ensure that pigs are kept in environments that provide sufficient space; are given suitable, healthy feed; and that waste is managed to prevent water or soil contamination. Does that mean that every pig farm is perfect? No. So does it mean that poor husbandry, environmental pollution and rampant overuse of pharmaceutical drugs is the norm? Absolutely not.

The casual listener might be horrified by the implications of antibiotic resistance for human health, but never fear, the drama suggests all will be well as long as your sausage comes from an organic Berkshire pig hand-raised on acorns. However, bacterial resistance to antibiotics occurs naturally and can be maintained or increased by any antibiotic use – in people, livestock or companion animals – not simply by use on conventional farms. Indeed, it’s vital to remember that organic operations are permitted to use antibiotics (as per the Soil Association organic standards), especially if they are the “best way to reduce suffering, save life or restore your animal’s health.” There is no blanket antibiotic prohibition on organic operations, as is often assumed.

Still more rhetoric invades the human health side of the drama – doctors try to dismiss and cover-up the public health implications, antibiotic researchers are hampered by lack of funds (possibly the most crucial but least discussed issue of the entire drama) and “big pharma” is lambasted for being more interested in developing drugs that generate long-term profit (e.g. diabetes or high blood pressure medication) than antibiotics that only need to be used once.

There is an immediate and definite need to develop new antibiotics both for animal and human health, yet if effective new drugs are found they’re unlikely to be distributed widely, but stored in case of an epidemic. Livestock farmers and vets have a huge responsibility in protecting both animal and human health, but so do doctors, food processors and ultimately all of us – simple hygiene measures, including effective hand-washing, are key to preventing the spread of disease.

Both national and global programs have been implemented to quantify, assess and reduce antimicrobial use; veterinary scientists are actively involved in on-farm research and interventions to reduce both antimicrobial use and resistance; and animal health companies (so-called”big pharma”) have joined with food processors, retailers, charitable foundations and human/veterinary medicine associations in taking a One Health approach (incorporating the health of people, animals and their environments) to making sure that antibiotics that are critically important for human medicine are withdrawn from animal use, and that the speed and spread of antibiotic resistance is reduced. Unless the rabid journalist has a serious epiphany in the third episode (to which I have not yet listened) it seems that facts are going to be overwhelmed by fiction as the efforts and advances made by global livestock producers are ignored.

I’m not suggesting that all drama should be absolutely true to life, but when real-life, topical, scientific issues are discussed, surely broadcasting agencies have a responsibility to be factual rather than alarmist? It’s unfortunate that this drama, written by a famous author and advised by a Professor of Microbiology at the University of Warwick, seems to have been developed without input from experts in veterinary science, animal production or on-farm antibiotic use. Furthermore, given the Wellcome Trust’s role as a global medical charity, one would assume that they have a responsibility to provide factual information, especially when their sponsorship must ultimately have been publicly funded. Instead, as with so many sensationalist dramas, it seems the world is going to end and we are the innocent victims of others greed for profit. Better switch to the organic sausage, or better still, the tofu surprise.

Jamie Oliver Should Be Presenting Friday Night Farming Facts – Not Feasting On Foodie Fiction

img_4311

Commercial dairy cows in Cumbria – should they be “retired” before slaughter?

Good grief. Just when I think I’ve heard it all, another food pundit comes up with an idea so daft that you could bottle it and sell it as vegan, gluten-free, dairy-free, humanely-reared organic water. The latest brainwave from Jamie Oliver is to “retire” old dairy cows onto pasture, where they can graze for four years before producing highly-marbled beef. Contrary to most of the breed-related marketing, Holstein beef is pretty good, so it’s a mouth-watering concept until we take a step back and think about the actual sustainability impacts.

Producing beef from cull dairy cattle? Excellent idea. I once had a heated argument with an activist protestor outside the Smithsonian Museum in Washington DC who seemed surprised that, when he told me that most cull dairy cows end up as burgers, I didn’t renounce my heathen ways and immediately seek out the nearest tofu burrito. It makes perfect sense – where would be the logic in discarding an entire cow’s worth (~301 kg) of nutritious, delicious beef simply to bury, burn or use the meat for non-food purposes? Indeed, ~50% of the UK (and ~24% of the US) beef supply comes either from cull dairy cows or dairy calves reared for beef.

Is there an argument for giving extra feed to cows that are going to be culled so that they get a little fatter and produce tastier beef? Yes indeed, adding value to cull dairy cows is a great idea, especially when the beef price is high. But here’s the rub. The average dairy cow in the U.K. is culled at 6.4 years of age. By that time she should have reached her mature weight, which means that the majority of extra weight she puts on in “retirement” is fat. Although we love the streaks of intramuscular fat that we see in a steak (marbling) and enjoy the depth of flavour that gives to the meat, the vast majority of fat on a carcass isn’t particularly edible. So we’re feeding a cow for four years of retirement in order to discard (or rather render into tallow – perhaps to make some £5 notes?) a significant proportion of the weight that she gains.

A cow will eat 2-2.5% of her body weight in dry matter every single day. Four years of feeding a 700 kg cow = 4 x 365 days x 700 kg x 0.025 = 25,550 kg of feed dry matter, or 106,458 kg of fresh grass given that it’s only ~24% dry matter. Plus 4-years worth of drinking water, manure and greenhouse gas (GHG) emissions. A hefty environmental impact compared, for example, to rearing two beef steers on the same amount of pasture over a 4-year period, in addition to culling the dairy cow when she leaves the herd (sans retirement). That scenario would provide 200% more beef (~900 kg total, even allowing for the lighter weight for grass-finished vs. grain-fed steers) from the same amount of pasture and with a smaller total quantity of manure and GHG emissions because the growing animals are lighter in weight throughout, therefore excrete and emit less*.

I can’t decide whether the increasingly asinine proposals for sustainable food production propounded by Jamie Oliver’s “Friday Night Feast” programme, which recently left the casual viewer with the impression that welfare of housed dairy cows is equivalent to that of battery hens are serious, or simply a way to court fame through controversy. However, the number of tweets lauding the programme’s food philosophy is alarming given the amount of time devoted to non-sustainable ideology. Time for TV programmers to redress the balance with some Friday Night Facts vs. Fiction?

*Note that I have not accounted for the beef cows needed to produce the steers, nor for the cost of rearing the dairy cow or the heifer needed to replace her in dairy herd. This is not a full system assessment, but simply about the best use of a unit of pasture area – adding fat to a mature cow (less efficient) or adding muscle and fat to growing animals (more efficient)

Low Meat, Faux Meat or No Meat – Should Retailers Really Reward Us for Buying Vegetarian Foods?

All food have an environmental impact

There’s no doubt that eating more fruit and vegetables is a positive idea. Nationally we still don’t hit our 5-per-day and lifestyle diseases are major causes of premature death. However, as Sainsbury’s redesigns aisles to try and convince shoppers to swap meat for vegetables and plans to issue extra loyalty points to customers choosing vegetarian foods, are we in danger of applying myopic solutions to a seriously complex issue?

Most people in developed countries eat more than the recommended 70 g of meat per day. If (and this is debatable) the researchers who claim that meat consumption is linked to lifestyle disease are correct, then reducing the amount that we eat may be a positive step. However, much of the justification for cutting meat consumption appears to be on the basis of reducing environmental impacts.

So how do we ensure that we eat a diet with a low carbon footprint? It’s very simple. Drewnowski et al. (2015) showed that grains, syrups and sugars had the lowest carbon emissions per kg of food – considerably lower than meat and dairy products. So we simply reduce the proportion of meat and increase the quantity of sugar that we eat each day. Just replace meat products with Mars bars and golden syrup and we’ll save the planet, albeit in conjunction with a spike in type II diabetes and a significant protein deficit.

If Sainsbury’s is determined to reward consumers for making healthier choices, why not do so based on the proportion of fruit, vegetables, lean protein and dairy purchased vs. cakes, biscuits and crisps; rather than giving extra loyalty points for vegetarian products? After all, a snickers bar or a packet of oven chips are both vegetarian, but meat-free foods are not inherently healthy choices. Furthermore, where do fish and dairy fit into the new regime? Given the low nutritional value of soy and oat juices per unit of greenhouse gas emissions compared to dairy, the potential for child malnourishment is considerable if plant-based foods are mis-sold as being nutritionally-equivalent to animal products.

Bipolar “A is bad, B is good” panaceas do nothing to improve consumer knowledge of food production or environmental impacts. Strawberries may have a lower carbon footprint than beef, but cannot be grown on a rocky slope in Scotland. Pork may have a relatively high water footprint, but almonds use even more. Lettuce is a great source of fibre, but provides very little additional nutrients per kg compared to meat. In my experience as an ex-vegan, the majority of vegan restaurant dishes are largely reliant on pasta or rice to bulk out the vegetables. Is this really a healthier choice than lean meat and vegetables? Given that many young people have little or no interest in cooking, is the presence of spiralised courgettes or cauliflower rice at the end of the aisle going to engender a sudden interest in all things gastronomic?

Most people’s diets are led (to a greater or lesser extent) by the foods available in the local supermarket, therefore retailers have huge opportunities to educate, encourage and improve our food choices. It’s not clear why Sainsbury’s would choose to launch this initiative, but it appears to be a box-ticking exercise, designed to address a single minor issue while ignoring the bigger problem.

The Future’s Bright; The Future’s…Meaty? A Response to Breakthrough’s Essay on Meat Production

jims-charolais-in-feedyardThis week I was asked to respond to an excellent Breakthrough article on the environmental impacts of beef production. As ever, I hope the comments below provide food for thought (pardon the pun) and I urge you to read the full Breakthrough article as well as the other comments by Jayson Lusk, Maureen Ogle and Alison van Eenennaam.

Every food has an environmental impact, whether it’s cheeseburgers or tofu, coffee or corn.

That shouldn’t come as a surprise to any of us and, as a scientist, sustainability consultant and parent, I don’t have a problem with food production being one of the biggest contributors to global environmental impacts. Why? Because food production is one of the few industries that are absolutely essential for human life. However, it’s clear that we need to take steps to reduce environmental impacts from human activity, and as such, the livestock industry is often criticised for both resource use and greenhouse gas (GHG) emissions.

Although meat production is predicted to increase from now until at least 2050, it should be noted that the trends for improved productivity and efficiency within global livestock industries also reduce environmental impacts. As described in Marian Swain’s essay on meat production, the US beef industry cut resource use and greenhouse emissions considerably between 1977 and 2007. Meanwhile, the rise of modern feedlot-finishing systems cuts land use, water use, and emissions per unit of beef compared to grass-finished meat.

These findings may seem intuitively incorrect as we’re constantly exposed to marketing and media messages suggesting that only grass-fed meats are environmentally sustainable, and that intensive livestock systems are undesirable. The data speak for themselves however—the majority of extensive systems finish cattle at lighter weights (thus requiring more total animals to maintain beef supply), have lower growth rates (so cattle take longer to grow to their finish weight) and often have lower reproductive performance in female cattle.

All these factors combine to increase environmental impacts. But when I presented this data to a group of French Masters-level Livestock Engineering students earlier this month, they were (in their own words) shocked. Even among experts and students, there remains a great deal of misunderstandings when it comes to meat production.

Does this mean that every beef producer worldwide should embrace feedlot-finishing and reduce pasture use? Absolutely not. One of the major benefits of cattle compared to swine and poultry is that they digest and use human-inedible forages, such that dairy and grass-fed beef cattle actually produce more human-edible protein in the form of milk and meat than they consume; and feedlot-finished beef cattle have a ratio of human-edible feed intake to human-edible protein output similar to that of swine, despite their greater overall land use. In keeping with the themes discussed in the Swain’s essay, there is no magic bullet—it is essential to fit production systems to the cattle, climate, market, and culture within each region and to improve productivity within each and every system.

So rather than reducing animal protein consumption as we move towards 2050, we might ponder keeping total consumption relatively stable, with a more equitable distribution across the globe? This would allow for a decrease in over-consumption in high-income regions, while providing a greater quantity of milk, meat, and eggs to those who have dire need for adequate animal proteins to maintain health and to promote adequate child growth and development. While the environmental impact of beef production is a key concern, we also have to examine the role of livestock in economic and social sustainability.  For billions of small-scale farmers, cattle provideeconomic viability, improved nutrition, social status and a means to diversify agricultural production as well as tangible benefits in terms of fertilizer, hides and other by-products.

Should we insist that global beef production is abandoned in favour of increased legumes, nuts or lab-created proteins? No. We simply need to give producers worldwide the education, tools and technologies to make the best and most efficient use of their resources. Only then will we have a truly sustainable (environmentally responsible, economically viable and socially acceptable) global meat industry.

Having Your Beef and Spending It? Don’t Let Moral Indignation Overcome Common Sense.

My Twitter feed has lit up like a firework this week with the news that cows are being murdered to produce the new plastic British £5 notes. Or, to correct the sensationalism with science, the notes contain a trace of tallow in the polymer that’s used to make them. Tallow is a by-product of beef production – it’s effectively the fat on the animal that we don’t want to eat, and has been used for centuries in a myriad of products.

Let’s be very clear here. No cows are being slaughtered (murdered!) to make £5 notes. Cattle are either slaughtered for meat or euthanised due to illness – there are no Bank of England-sanctioned posses stringing up helpless cattle as a license to print money (literally). Fortunately, we are able to use the portion of the animal’s carcass that we can’t (or won’t) eat to manufacture products that would otherwise rely on synthetic chemicals.

Not surprisingly, the majority of the outcry has come from vegetarians and vegans. While I will defend the right of anybody to choose what they eat or wear (note that I am not criticising or denouncing anybody’s religious beliefs here), the current protests seem to be slanted towards choosing to be offended by a minor point, rather than any semblance of logic.

According to a rather nifty (yet accurate) calculation by the guys at Vice, it would take 23 kg of tallow to make all the new £5 notes that will be in circulation by the time the old ones are phased out. The total tallow yield per animal is ~40 kg, so it would take just over half of one animal (23/40 = 0.58) to produce all the tallow for the UK’s total £5 note requirements.

5-noteMany of those who are protesting are vegetarian (as opposed to vegan), thus still consume milk, eggs, honey and other non-meat animal products. Given that 20% or more of the cattle slaughtered in the UK are adult cows and bulls (i.e. they have reached the end of their productive life in the dairy or beef herd rather than being specifically reared for meat), it makes sense to utilise whatever components of their carcasses are suitable for industrial purposes rather than diverting them into landfill or incinerators. If dairy consumption is acceptable to vegetarians, can it really be claimed that bank notes containing a fraction of the spent dairy cow’s carcass as tallow are not?

by-products-from-animal-agAs I have mentioned in previous blog posts, myriad everyday products contain by-products from cattle. Given the current outcry, once can only assume that those who shun the new £5 notes also refuse to travel in cars, buses or on bicycles (as (t(as tyres contain stearic acid, again from tallow); do not drink from bone china mugs; or disavow beer filtered through isinglass. Or, as with so many other issues, is it an opportunity for a small minority to protest and promote their personal dietary choices behind the guise of population-wide offence?

The online petition against the new £5 notes currently has >129,000 signatures. Obviously we all have the right to protest against issues that alarm, anger or offend us, and social media gives those opinions far greater weight than we had in the past. Yet is this really an issue that is more important (as judged by media coverage) than 11-year-old girls being forced into marriage? Or livestock being slaughtered without first being stunned? Or asylum seekers being refused entry? Perhaps in this case, the moral minority need to examine the bigger picture, and consider the issues that really matter.

 

 

 

Where’s the Beef? Not in Danish Diets.

Culvers burgerFor those of us in the UK, mentioning Danish livestock production almost inevitably leads to thoughts of Danish bacon (be still my beating heart) – a considerable proportion of their 90% of domestic pork products that are exported. However, any beef lovers in Denmark may be in trouble, as recent news articles suggest that red meat (beginning with beef) will soon be taxed in order to cut consumption and meet greenhouse gas targets.

Despite the number of voices clamouring for reduced meat consumption, it seems clear that the average consumer isn’t going to forgo meat and dairy simply because a new study is publicised in the lay press. I’m firmly of the opinion that the only way that meat consumption will decline is if it becomes too expensive to include in the weekly shopping basket. Indeed, although meat consumption per capita has declined in the USA over the past 10 years, demand (as measured by the price that the consumer is willing to pay) has increased over recent years.

So will taxing meat lead to a reduction in consumption? For those who routinely order a 16 oz (454 g) steak in a restaurant or think nothing of tucking into a chateaubriand, probably not. High end cuts of beef are associated with celebrations and luxury dining, and going out for a broccoli pasta bake just doesn’t have that same ring to it.

However, we live in a world where 793 million people (10.7 % of the global population) are undernourished – and that isn’t simply confined to people in developing regions. That means that almost 1 in 9 people do not have enough food. To low-income consumers, food availability isn’t simply a function of what is on the shelf in the supermarket, it’s directly related to economic cost and convenience. If red meat is taxed, it will still be eaten, but there will be a disproportionate shift towards consumers with a greater income and away from those who are in most need of affordable high-quality protein, including growing children.

Do beef alternatives exist? Absolutely – protein can be supplied from other meats, fish or vegetable-based foods. Yet here’s where the convenience aspect comes in – most of us can probably think of a quick and easy recipe involving beef, but how many can you think of involving tofu or lentils? That’s not to say that we shouldn’t expand our cooking repertoires, but when time is at a premium, quick easy recipes that will feed a family win every time.

If beef becomes unaffordable, it will have to be replaced by another protein – but this substitution does not occur at zero cost. Can tofu or lentils be produced on low-quality pastureland where we can’t grow other human food or fibre crops? Do pork or poultry make such efficient use of forages, pastures and by-products from human food and fibre production that, far from competing with humans for food, the animals produce more human-edible energy or protein than they consume? No. The only livestock that do this are those pesky greenhouse gas-belching bovines.

Greenhouse gases are important, but they are not the only factor that we should consider when advocating for sustainable dietary choices. In a world where millions of people are food-insecure, removing a protein choice from the table of those with low incomes simply adds to the problem of how to feed the world – sustainably.
