With all the background information we have gathered over
the last few weeks, we can finally kick-start the review of modern food
production practices, by looking at the global impacts of intensive livestock farming.
I must stress that I have tried hard to look at the evidence with unbiased eyes,
ditching any preconceptions I may have previously held. However, this is,
admittedly, no piece of cake! We’ve all heard horror stories of the factory
farming industry, and the internet does not fail to keep them coming, by
hosting a wide inventory of sensationalist articles, videos and pictures that
will put you off meat for good... Well, until you’ve miraculously forgotten
about it a few minutes later… (Guilty!) So, to avoid being misinformed, I have largely structured
my reading on scientific papers, research and well-cited articles, whilst still
considering some element of opinion
from credible organisations, albeit with a pinch of salt.

Now let’s start with the bare facts. This year, the Food and
Agriculture Organisation (FAO) estimated the global average meat consumption to be 41.30kg per capita, with the average consumption in industrial countries
(e.g. European countries, USA and Australia) to be 2.32 times this figure, roughly
equivalent to 262g of meat per person per day. For comparisons sake, this is
equates to eating about 9 rashers of bacon, or 3-4 sausages, or 2⅓ quarter-pounder
burgers each day. However, if we revisit the FAO’s figures we see that, since
1964/66, the average consumption in industrial countries have increased by a
factor of 1.56, whereas in developing countries this is a factor of 3.10! Despite
this, western countries still devour a heck of a lot more meat than developed
countries, by over threefold!
Why is this an issue? What’s so bad about meat? Despite the
recent connection found between cancer and processed/red meat, in
moderation, meat can contribute as part of a healthy, balanced diet, providing protein,
minerals (e.g. iron) and vitamins (e.g. B12). Yet, with plenty of other
non-animal sources of these essential nutrients, the question stands: are we
consuming and producing more meat than necessary? Current estimates suggest
that livestock production is responsible for approximately 14.5% of global Anthropogenic greenhouse gas emissions (FAO, 2013). Shockingly, 61% of these emissions were generated by cattle alone via both the meat and dairy industries, whilst
poultry (incl. meat and eggs) and piggies only generate 8% and 9% respectively… So, what’s going on here? Where are all these emissions coming from? Before
we look at the environmental implications, we must first consider the current
methods of practice that put the meat on our plates.
I’m not sure about you, but when I think of meat production,
my thoughts immediately turn to factory farming, characterised by large numbers
of animals crammed into restricted space and requiring substantial quantities
of food, water and antibiotics. This comes as no surprise as, globally,
factory farming contributes to about 72% of poultry production, 43% of egg production, and 55% of pork production, with suggestions that figures for cattle are slightly lower (although this is not conclusive). These percentages
are pretty high, but are honestly a bit lower than I anticipated! Saying that,
in countries like the USA these figures are generally greater than 90%, with
exception to cattle with approximately 78% raised from factory farms,
which probably explains my initial perception of the situation.

Regardless, intensive livestock farming is the dominant
method of meat and dairy production in the world, and continuously raises
ethical concerns for animal welfare, such as, the confinement to metal cages to
restrict movement, reduced (or lack of) access to fresh air and natural light,
and removal of tails and beaks to reduce loss of livestock through aggressive
behaviour (most likely due to heightened tensions caused by poor living
conditions). Additionally, the desire to boost productivity of the end “product”
which can cause adverse effects, for example, increased growth rates of
chickens leads to higher risk of lameness, increased egg yield in laying hens
can lead to osteoporosis, and greater number of offspring can lead to higher
infant mortality. Not to forget concerns over human welfare… With large
agribusinesses on the rise, small farmers are on the decline, as some are
unable to compete with these vast, industrial practices at the same low
cost.To some, this may seem like fair game, but this produces a net
decline of labour force, thus resulting in less available jobs.
Most of this is probably nothing new to you. We all know
this stuff, to a degree, and since it’s incredibly easy to detach yourself from
the reality, it becomes very easy to ignore. You don’t often see the
industrial process. You can’t truly measure an animal's emotional response. Plus, meat
is so readily available, it doesn’t take a second thought. However, the
environmental implications are a lot harder to ignore, or at least will be as
time goes on. Deforestation, greenhouse gas emissions, water source contamination…
The list is endless! Yet, a lot of us still aren’t that clued up about the full
extent of the impacts in an environmental context. So, instead of shying away, join me for part 2, as I explore the major impacts
that meat production is having on our planet, and how we can predict the future effects using modelling.
