pays the true price of cheap meat?
Meat has become a ubiquitous part of our diet. In the last thirty
years global meat production has nearly doubled and is projected
to further increase drastically. People in western societies often
eat meat three times a day, with the average yearly consumption
of 90 kg of meat per person. Many believe meat is an essential source
of protein and its daily intake is important in a well balanced
diet. Yet, doctors are warning that the current level of meat consumption
is unhealthy. High meat consumption is related to higher gastric-cancer
risks, higher rates of cardiovascular diseases, and increased cholesterol
People having a
diet rich in animal instead of vegetable fats are also nine times more
likely to develop Alzheimers disease. In fact, during most of
human history our diet was based on grains and vegetable protein, meat
being consumed only occasionally.
While the direct health risks are worrying, there are broader implications
of the ever-growing addiction to meat. Here are a few simple facts:
1) About 70% of the entire worlds agricultural land is in some
way used for farming animals, either as grazing land or as crops for
fodder. Worldwide 80% of all soybeans, valuable source of proteins for
people, are used as animal feed.
2) Today, animal farming produces 18% of greenhouse gas emissions. For
comparison, the entire worlds transport system combined (including
all cars, planes and ships) produces 13.5%.
3) Animal farming is one of the main forces driving deforestation. About
70% of Amazon rainforest has been cleared to produce land for new pastures
or land for livestock fodder crops. The meat produced in these lands,
however, contributes little to the diets of Brazilians, and mostly ends
up in the USA and Europe. Given that deforestation is responsible for
a further 20% of greenhouse gas emissions and combined with emissions
from animal farming, meat consumption clearly is a major contributor
to global warming.
4) Animal farming requires vast amounts of water, an increasingly precious
resource. Depending on species and farming type, a kilogram of beef
requires between 13 000 and 100 000 litres of water to produce. By comparison,
a kilogram of wheat requires just 1 000-2 000 litres.
5) Most of the animal farming in Europe and North America is conducted
in factory farms, and rising demand for meat will increase this practise.
Factory farming, in turn, brings with it a long list of environmental,
public health and ethical issues associated with growing animals as
quickly and cheaply as possible and keeping them crowded, without sunlight,
possibility to move, and in suffering.
6) Large quantities of antibiotics are used in factory farms as a "prophylactic"
measure to prevent diseases; their use in the Netherlands increased
by nearly 30% from 2003 to 2005. This provides ample opportunity for
bacteria to develop antibiotic resistance. Such antibiotic resistant
bacteria (also called "superbugs") have now been found in
20% of Dutch pigs, 21% of chicken and 3% of cows; the situation in other
countries is likely to be similar. The bacteria are transmitted to humans
and potential harmful impacts of their spread are hard to overstate.
In Dutch hospitals farmers are already kept in isolated rooms. The meat
they grow is exported all around Europe and beyond.
7) Despite antibiotics densely packed animal farms provide a perfect
place for creating new strains of viruses and bacteria. Moreover, traditional
animal breeds are now replaced by fast-growing varieties, wiping out
the genetic diversity of the entire livestock industry, a legacy of
thousands of years of careful breeding. Because animals are now so alike
all around the world, diseases can spread particularly fast. The appearance
and spread of avian influenza and mad cow disease is believed to be
facilitated by factory farms. During the previous epidemic of foot-and-mouth
disease in the United Kingdom 600 000 cattle and more than 3 million
sheep have been slaughtered and burned, causing billions of euros losses
for the meat-industry, but also taxpayers.
These are only a few illustrative facts. The full list is much longer:
pollution of water and atmosphere by billions of tons of manure, emissions
of nitrous oxide which contributes to acid rain, intensive use of pesticides
and fertilizers and overfishing to produce fodder, driving indigenous
peoples off their land to raise export crops for animal fodder
The globalisation of the meat industry has resulted in less awareness
about the true price and quality of meat we are buying. We often assume
meat in our shops comes from local sources, but large quantities of
meat to Europe are imported from Brazil and New Zealand.
Fish, while promoted as a healthy meat substitute, is unfortunately
not necessarily a good option either. First, nowadays marine fish often
have excessively high levels of organic pollutants and toxic metals
such as mercury. Second, most of current industrial fishery and aquaculture
cause grave environmental problems, with nearly 80% of world fish stocks
being depleted and marine ecosystems damaged.
Albert Einstein once famously predicted that the largest step in human
evolution will be the change to a vegetarian diet. And that is happening.
There is also an alternative approach animals grown locally and
grazed outside in low densities. This is also the best source of diary
products. First, meat and milk from animals that are growing at their
normal pace and eat their usual food is healthier and tastier. Second,
raising animals in small densities outside can even benefit the environment,
as moderate grazing intensity helps to create rich biodiversity in meadows,
that might otherwise become overgrown with shrubs; small amounts of
manure in turn naturally fertilizes the soil. Sure, such meat costs
more. Yet, the misleadingly low price of meat in shops today hides the
true cost of the associated health problems, climate change, deforestation,
water pollution and "superbugs" costs not visible on
the price tag. We are all paying the latter.
