Passionate about sustainability and livestock production, dedicated to giving farmers and food industry stakeholders the data and messages to explain why we do, what we do, every single day.
The Chipotle short film “Back to the Start” which was featured in a commercial break during the GRAMMY awards on Sunday has been one of the most discussed topics on Facebook and Twitter in the past week.
It is incredibly powerful film. Beautifully animated and featuring Willie Nelson singing Coldplay’s “The Scientist”, the cartoon pigs are pink and symmetrical; the dairy cattle graze green grass (before their incarceration in a barn) and antibiotics come in cute little capsules. It’s even more potent because it represents a classic human theme – a mistake followed by redemption. Walking alone in the cold winter night, the farmer realizes his mistake in intensifying his production system, tears down his barns and lets his animals roam free. Who doesn’t love a classic redemption film?
Many of my agricultural friends have responded to this film with the entirely valid argument that Chipotle lack integrity by producing this film as they only source natural or local-produced meat where available. This marketing strategy therefore condemns a significant proportion of their suppliers who produce conventional meat and dairy. However, the average consumer, who only sees the film because they’re waiting to watch Adele’s latest GRAMMY acceptance speech, don’t read about the integrity conflict, and if they do, may assume it’s a reactive response by the ‘inherently biased’ animal agriculture industry.
The question then becomes, how do we overcome this powerful, yet discriminatory message with the fact that all systems have a valid place in food production? Bill Donald (Immediate Past President of NCBA) attended the World Food Prize in Des Moines this week and told me that the hot topic was the concept of future farms with ‘circular economies’. This means taking the ‘reduce, reuse, recycle‘ concept of a circular economy and incorporating it into agriculture, so that the consumer can see that every stage within the process reduces waste, saves resources and produces both nutritious food and useful by-products. It’s a huge hit with consumers in China who are becoming more concerned about environmental issues.
Ironically, this is nothing new – it’s the basis upon which beef production is founded. We take a human-inedible product such as grass, feed it to animals that provide us with meat, leather, pharmaceuticals and other by-products, use their manure to fertilize and grow the grass, produce more beef… It’s a closed and continuous circle of life that has used fewer resources and emitted less greenhouse gases year on year. Yet that’s a very different image to the intensive, inefficient system portrayed by the Chipotle film.
Agriculture is not and never has been a collection of factories pumping in antibiotics, churning out identical widget animals and releasing toxic green waste into rivers. The challenge ahead of us is to be proactive and to demonstrate beef’s circle of life to consumers – not only the 3 R’s (reduce, reuse, recycle), but the 4 F’s – food, fertilizer and fuel for the future.
A recent article by Andrew Jack in the Financial Times (the iconic pink-colored newspaper carried by all self-respecting business men on London tube trains each morning) reports that developing countries in Africa will be responsible for the greatest increases in population growth over the next 90 years, with the global population predicted to hit 10 billion by 2100. Given the number of dire predictions currently being bandied around regarding population increases, food demand and climate change it’s easy to become blasé and dismiss it as just another issue that will be solved by the next generation. After all, what difference can we possibly make to rural communities in developing countries?
Rises in per capita are predicted for developing countries over the next century and as Andrew Jack notes, increasing affluence results in improved healthcare, urbanisation and a decline in birth rates. Nonetheless, this pattern is not being currently being exhibited by regions in Africa and S. Asia, which are unable to improve per capita income as population increases overcome economic growth.
So how do we curtail the rise in population growth? Even in a developed country such as the USA, mentioning the politically-charged phrase “population control” often leads to an uncomfortable silence, images of an Orwellian constraint on family size (1 child good, 2 children bad?) or debate over the rights and wrongs of abortion. Yet simply providing access to contraception, considered to be an inherent human right by many women in the developed world, could conceivably (pardon the pun) improve future sustainability.
Reducing the number of children born in developing countries would improve female health and lessen the burden on economic and environmental resources placed by increasing population size. This would be a crucial step forwards in mitigating future food shortages, yet it does not solve the underlying problem. One of the major drivers behind population growth is parental reliance on support from the younger generation. As discussed in Jared Diamond’s excellent book “Guns, Germs and Steel“, higher birth rates potentially allow for a greater number of children to work on the land and improve societal stability. However, the promise of future affluence is a major stimulant that causes young people to migrate from rural areas to urban regions that are already suffering from significant overcrowding.
A considerable yield gap exists between developing and developed countries, both in terms of animal and crop production. If productivity could be improved and the yield gap reduced, food security would improve in rural areas with positive effects on per capita income and infrastructure, and potential reductions in the number of inner-city migrants. Nonetheless, the major question remains unanswered – how to improve productivity?
If we use dairy farming as an example, a recent report from the Food and Agriculture Organisation noted a negative relationship between productivity and carbon footprint – as we move across the globe from developed to developing regions, productivity decreases and the carbon footprint per kg of milk increases (see graph). Carbon can also be considered a proxy for land, water and energy use, thus reduced productivity increases both resource use and environmental impact. The logical conclusion would therefore be to implement systems and management practices currently seen in N. America, Europe and Australasia in an attempt to educate farmers in S. Asia and Africa. However, sustainability cannot be improved by implementing a one-size-fits-all solution, but calls for a region-specific approach.
Identifying traits within indigenous and imported animal breeds and plant varieties that will make the best use of available resources allows development of production systems that match environmental, social and economic demands. Further implementation of continuous improvement and best management practices in developing countries is crucial in order to improve affluence, reduce population growth and mitigate environmental impact both now and in future. However, this is not a situation that can simply be solved by improving yield per acre, but requires a multifactorial approach coordinating population control, education, food security and human health and welfare. Providing contraception without a concurrent effort to improve agricultural productivity will fail in its prophylactic intent to control either population growth or world hunger.
Would you replace your hamburger with a soy burger?
Ah, the power of a report from an earnest non-governmental organization, out to save the consumer from themselves. Destined to be selectively quoted for the next 20 years and to prove once and for all that, as the comedian Ron White would say: “You can’t fix stupid”.
Released this week, the Environmental Working Group’s report, claimed not only that everybody should eat less meat, but that “Meat, eggs and dairy products that are certified organic, humane and/or grass-fed are generally the least environmentally damaging…Overall, these products are the least harmful, most ethical choices.” This is a surprisingly intuitive conclusion in that it utterly contradicts the body of scientific knowledge to date, and as the report doesn’t contain any data on anything other than conventional production systems, let alone ethics.
The requisite environmental activist components are there: stylized pastoral scene on the cover and such a liberal sprinkling of emotive words such as “confined” and “polluting” it seems like an ice-cream sundae assembled by a small child with a sugar addiction. It’s even been peer-reviewed by “experts” (as you may have gathered, when reading this post, words in quote marks should be accompanied by an ironic raised eyebrow).
It’s a bona-fide report with colorful graphs, acknowledgements, a whole separate report on the methodology (which guarantees nobody will read it) and data! As we all know, data is powerful. According to their “calculations”, lamb has the greatest impact, generating 39.3 kg (86.4 lbs) of carbon dioxide equivalents (CO2e) for each kilo eaten, and beef has the second-highest emissions, generating 27.1 kilos (59.6 lbs) of CO2e per kilo consumed. Cheese generates the third-highest emissions, 13.5 kilos (29.7 lbs) of CO2e per kilo eaten. Everybody knows that data doesn’t lie. Cold hard numbers are based on science. Yet just as I can replace ground beef with tofu and make something that looks like a burger, yet tastes like… soy, so has the EWG have used poor-quality data and erroneous assumptions to create a vegetarian ideology that is a poor substitute for real science.
They claim that if everyone in the U.S. chose a vegetarian diet, it would reduce US carbon emissions by 4.5%. This is an impressive achievement since the Environmental Protection Agency cites livestock production (including dairy, eggs and horses) in the US as accounting for 3.12% of total emissions. Who knows where that extra 1.4 percent comes from?
The animal component of the report shows a lamentable lack of basic livestock production knowledge. In the beef example, the cow-calf and stocker operations are based on a lot feeding system in Nebraska rather than rangeland production and by-product/forage feeding. All the animals raised are steers (what on earth happens to the heifers?) and there appear to be no bulls in the system, not to mention the lack of dairy calves entering the feedlot and cull beef or dairy cows entering the production chain. Crucially there is no data on herd dynamics, bodyweights, growth rates, and total time required for animals to reach slaughter weight – the most important factors that affect the carbon footprint of a unit of beef.
The lamb system does contain rams as well as ewes, but there is no data relating to the flock, and most crucially, to the lambing rate. US farm flocks average 1.5 to 2.5 lambs per ewe per year whereas range flocks average 1.0-1.5 lambs per ewe. If we compare this to the US average for beef according to the most recent USDA/NAHMS report of 87% of cows producing a live calf, that means we need roughly twice as many beef cows to produce offspring as we do ewes, even considering the fact that lamb produce slightly less meat per carcass on a percentage basis (for a more realistic estimate of meat yields than those quoted in the EWG report, the University of KY have a nice extension publication on the subject).
So here it is, the issue that every single life cycle assessment involving animals and executed by LCA engineers to date misses – the fact that for every day an animal is alive, it needs a certain amount of energy and protein (and therefore feed, land, fertilizers, fossil fuels etc) simply to stay alive. This is called the maintenance requirement and it’s exactly the same principle that leads to that nifty “The average woman requires 2,000 calories, the average man requires 2,500 calories” credo that’s on almost every nutritional label. It doesn’t take a giant deductive leap to realize that if a certain amount of feed is needed to maintain an animal, there’s going to be a certain amount of waste too – which means manure and greenhouse gases. Breeding animals in meat production are the biggest contributors to the total carbon footprint precisely because they consume resources and emit greenhouse gases each day, yet only end up in the human food chain after a number of years, if at all.
If I’m making a bun for my tofu burger, it’s more efficient to cook it in an oven that can produce two or three buns rather than one. Exactly the same analogy applies to breeding herds – a larger breeding herd with reduced reproductive efficiency (i.e. fewer offspring per female), means more resources and a greater carbon footprint per unit of milk or meat. Lamb’s carbon footprint would be expected to be approximately half to two-thirds that of beef given the greater reproductive efficiency, yet the EWG’s estimation has lamb at 44% higher – a clear reflection of the invalidity of their results.
Comparing the carbon footprint of different meat products is an elegantly futile competition in which nobody wins. According to their “data” beef is a better choice than lamb, chicken is better than pork. Yet who fancies chicken Wellington for dinner? Or egg pot pie? Or a pea McMuffin? The idea that we should be happy, saving the world on a diet of tofu and lentils is somewhat ironic given their propensity to produce increased methane from the human gastro-intestinal tract.
Are all 311 million people in the US going to rush to the grocery store and fulfill the EWG’s somewhat desperate cry for Meatless Mondays? Until all human activity can be put into context and the effect of driving to work vs. buying French wine vs. eating an 18-oz T-bone vs. having a third child can be compared objectively, this report is simply another one-week-wonder, destined to be quoted in every vegetarian manifesto and vegan twitter post (presumably vegans don’t tweet, as that would be exploiting birds?) but forgotten as soon as Katherine Middleton wears a new dress on a royal visit or yet another politician demonstrates their indirect support for the pork industry by increasing Google searches for “wiener”.
For a little light relief, here’s Ron White’s take on “Stupid” (please do not watch if easily offended)
