T
he figures were so astounding that I refused
to believe them. I found them buried in a foot-
note, and assumed at first that they must
have been a misprint. So I checked the source,
wrote to the person who first published them,
and followed the citations. To my amazement, they
appear to stand up.
A kilogramme of beef protein reared on a British hill
farm can generate the equivalent of 643kg of carbon
dioxide. A kilogramme of lamb protein produced in the
same place can generate 749kg. One kilo of protein
from either source, in other words, causes more green-
house gas emissions than a passenger flying from
London to New York.
This is the worst case, and the figure comes from a
farm whose soils have a high carbon content. But the
numbers uncovered by a wider study are hardly reas-
suring: you could exchange your flight to New York for
an average of 3kg of lamb protein from hill farms in Eng-
land and Wales. You’d have to eat three hundred
kilograms (300kg) of soy protein to create the same
impact.
In choosing what we eat – or making any other choice
– we appear to take informed and rational decisions.
But what looks and feels right is sometimes anything
but. In this case, the very features we have been led to
see as virtuous – animals wandering freely across the
mountains, tended by horny-handed shepherds, no
concrete and steel monstrosities or any of the other
ugliness of modern intensive farming – generate aston-
ishing impacts.
The figures are so high because this form of hus-
bandry is so unproductive. To produce one lamb, you
need to keep a large area of land bare and
fertilised. The animal must roam the hills
to find its food, burning more fat and pro-
ducing more methane than a stalled
beast would.
Yes, there are payoffs here. What is
good for farmed animals is often bad for
the natural world. The cruelties of inten-
sive indoor production are matched by
the wreckage of extensive outdoor pro-
duction. Free-range pig and chicken
farming, practised on the current scale,
can be environmentally disastrous.
Nitrates and phosphates sometimes pour
from their paddocks and into the rivers. Unless they are
kept at low densities or on well-drained fields, pigs tend
to mash the soil: a friend describes some of the farm-
ing he’s seen as opencast pig mining.
You can raise production – which means fewer green
-
house gases per kilo of meat – by dosing your animals
with hormones and antibiotics. But this too has a cost.
It’s now almost too late, the director of Antibiotic
Research UK warned this week, to prevent a global
superbug crisis. This is partly because unscrupulous
farmers have been chucking shedloads of the antibiotic
colistin – the last great hope of killing resistant bacte-
ria – at their animals, as it raises their weight.
But of all forms of production, the most attractive is
one of the worst. Hill farming not only makes a wildly
disproportionate contribution to climate change; it also
trashes our watersheds, increasing the chances of dan
-
gerous floods, and destroys what would otherwise be
our wildlife refuges: the great empty uplands, in which
economic activity is sustained only through lavish farm
subsidies. It is hard to think of any human activity with
a higher ratio of destruction to economic product.
My friends in the industry accuse me of being anti-
farmer. Its true that I emphasise the dark side, largely
because so few other journalists seem prepared to
cover these issues. But I have no visceral dislike of
farming – quite the opposite. Visiting a farm on Exmoor
last week, I was reminded of all that is beautiful about
keeping sheep. The Arcardian idyll, a conception of the
shepherd’s life (in both Old Testament theology and
Greek pastoral poetry) as the seat of innocence and
purity, a refuge from the corruption of the city, reso-
nates with us still. But in the midst of a multifaceted
crisis – the catastrophic loss of wildlife, devastating
but avoidable floods, climate breakdown – entertaining
this fantasy looks to me like a great and costly
indulgence.
As for eating local food, well in some cases it makes
sense. It helps to engender a sense of place and belong-
ing, which should not be lightly dismissed. When we buy
seasonal fruit and vegetables from local farmers, it
works environmentally as well. But we’ve tended to over
emphasise food miles and to under emphasise other
impacts. On average, transport accounts for just 11% of
the greenhouse gas emissions caused by the food indus-
try. Pulses shipped from the other side of the world can
cause far lower impacts than meat produced here.
A paper published in December suggests that switch-
ing from meat to green vegetables would be
environmentally damaging. Per calorie, growing let
-
tuces produces more greenhouse gases than rearing
pork. But all this establishes is that lettuces are low in
calories. You would need to eat 15kg of lettuce to meet
your daily energy requirement, which might be reason-
able if you were a 200kg rabbit. As another study
remarks, “20 servings of vegetables have less green-
house gas emissions than one serving of beef.
As the world’s people adopt the Western diet, a paper
in Climatic Change estimates, the methane and nitrous
oxide produced by farming could rise to the equivalent
of 13 billion tonnes of carbon dioxide per year by 2070.
This is more than all human activities combined can
safely produce without exceeding two degrees of global
warming. Climate breakdown looks inevitable – unless
we change our diets.
This, above all, means swapping most of the animal
protein we eat for vegetable protein. It’s not painful,
unless we make it so. Many British people used to eat
dhal every day. They called it pease pudding, pease
pottage or pea soup. As in South Asia, its ingredients
varied from place to place and season to season. It’s
just one component of a diet that offers plenty of vari-
ety – without trashing the great variety of life.
I’m not suggesting that you eat no meat or other
animal products. I am suggesting that we should all eat
far less.
