than driving cars. Consuming steak regularly
might be considered more environmentally-del-
eterious than driving an SUV.
The Green Revolution which began after World
War II has allowed the consumption of meat to
reach these unsustainable levels. It doubled crop
yields around the world but depended on finite
fossil fuels: herbicides and pesticides are by-
products of oil; synthetic fertiliser is produced
by burning natural gas; the harvesting, planting
and drying of grain all demand significant energy
inputs.
Much of what is cultivated is not consumed
directly: 80% of US grain is fed to animals. Since
the 1960s, average per capita meat consumption
in many countries, including Ireland, has doubled.
On average 6 grams of plant protein is required
to yield 1 grams of meat protein. Beef along with
meat from other ruminants is the least efficient.
With a rising population and peak oil on the hori-
zon a calamitous future may await, especially as
Third World diets converge with those in the First.
Vaclav Smil estimates that if the world’s growing
population decides to eat the same amount of
meat that the world’s affluent minority now con-
sumes, we would need 67 percent more land than
the earth actually contains.
In his book ‘Just Food’, agricultural historian
James E McWilliams reaches a stark conclusion:
“every environmental problem related to contem-
porary agriculture that I’ve investigated ends up
having its deepest roots in meat production …
Monocropping, excessive applications of nitrogen
fertilizer, addiction to insecticides,
rainforest depletion, land degrada-
tion, topsoil runoff, declining water
supplies, even global warming – all
these problems would be consider-
ably less severe if global consumers
treated meat like they treat caviar,
that is, something to be eaten rarely,
if ever”. Howard F Lyman goes so far
as to say: “To be an environmentalist
who happens to eat meat is like being
a philanthropist who doesn’t happen
to give to charity”.
Green Delusions
It is incorrectly assumed that Irish
beef is a pure product of terroir. In
reality, grain, most of it imported
and one million tonnes of it geneti-
cally modified, forms, on average, nearly 40%
of their diet. Synthetic fertiliser boosts the grass
they graze and pollutes the water. But apart from
external inputs, grass-fed cattle actually produce
four times more methane through enteric fermen-
tation than their feedlot cousins.
Teagasc, the Irish Agriculture and Food
Development Authority admits: “Ireland is unique
among the EU countries for the proportion of its
greenhouse gas (GHG) emissions which origi-
nate from agriculture, representing 29.1% of
national and 40% of the non-Emissions Traded
Sector (non-ETS) emissions”. This is compared to
an EU average of 9%.
Among developed economies only that other
island of livestock, New Zealand, has a higher pro-
portion of emissions associated with agriculture.
Teagasc’s submission to the derailed Climate
Change Bill disclaims any responsibility for Irish
agriculture: “the impact of rising food demand
means, other things being equal, that a reduc-
tion in food production in Ireland to
meet national GHG reduction targets
would result in increased food pro-
duction elsewhere.
This can result in a net increase
in global GHG emissions, if the coun-
tries expanding food production were
unable to produce food with an emis-
sions intensity that is as low as in
Ireland”. But this argument ignores
that the production of Irish beef is
heavily subsidised. McDonalds pur-
chases Irish beef because it is cheaper
than the alternatives, not because it
is has a better environmental record
or is higher quality. An artificial-
ly-low price increases demand for
hamburgers. Moreover, Irish beef
is aggressively marketed at home
and abroad. The Minister for Agriculture Simon
Coveney is currently attempting to bypass the EU
and sell directly to the Chinese market.
With each new trade deal his popularity rises
and he is seen by many as a future
leader of Fine Gael. The EU could
curb demand for beef by increas-
ing tariffs to take account of its
contribution to global warming. In
certain scenarios embargos could
be applied. Third World production
can be curbed by reducing demand
in the First. Europe can be a beacon
of responsibility.
Teagasc also ignores how, if we
move away from livestock produc-
tion, we could plant more forests
thereby off-setting our emissions and
satisfying long-term energy require-
ments with carbon-neutral fuel; we
would also increase biodiversity and
make the country more attractive to
tourists; while forest-gardening and
permaculture offer sustainable sources of food.
Furthermore it seems likely that consumers,
in the developed world at least, will alter their
consumption to take greater account of beef’s
environmental impact and health consequences.
Our agriculture model may become obsolete just
as British coal mines did.
Alternatives
The option of developing our dairy sector at
the expense of beef production offers some
encouragement but the same environmental haz-
ards apply, albeit with greater energy yields. In
bygone times, when dairy formed an important
component in the diet, the population was below
one million and most consumption was on a sub-
sistence level; low level production preserved
many of our woodlands.
We can certainly maintain that sector but
instead of moving towards mass production we
should focus on quality, nutritious produce: arti-
san cheeses and non-homogenised,
even raw, milk should be promoted
instead of being stymied by over-
regulation. These will have more
value added and can create greater
employment than the powdered milk
produced by multinationals that our
government flogs to the Chinese.
Cattle should be integrated into
agriculture, allowing their manure to
be used as fertiliser in mixed farms,
rather than generating further meth-
ane as it decays in feedlots.
Diversifying production would
certainly benefit our tourist sector:
a recent poll found that only four per-
cent of visitors come to Ireland for
its food.
Perhaps in this time of economic
hardship we should not reform a profitable sec-
tor. But it is important to analyse wider costs. The
government’s promotion of domestic beef con-
sumption is potentially injurious to the health of
the population, thereby increasing medical costs
and reducing productivity.
The author of a recent study of the Harvard
School of Public Health featuring 100,000 men
and women concluded that “regular consumption
of red meat, especially processed meat, contrib-
utes substantially to premature death”.
Human health will not suffer if we abandon
meat consumption altogether. On the contrary,
the China Study (2005), a comprehensive epi-
demiological survey conducted over twenty years,
revealed that a plant-only, wholefood diet min-
imises or reverses the development of chronic
diseases. Contrary to the nutritional myths that
abound, plants provide ample protein sources.
In Ireland we should grow crops for human
consumption. The challenge is to re-think the
whole model of food production in Ireland. The
UN has declared 2013 the year of Quinoa; known
as Mayan gold, it contains all our essential amino
acids and grows well in temperate conditions just
like the potato, another Andean crop.
We should embrace it. Without an awareness
of methane emissions or health studies our ances-
tors seem to have developed a taboo against beef
consumption. In our complex and unsustainable
world that taboo would be wiser still.
