Free Term Paper on Biotech Foods
| In Michael Pollan’s essay, “Playing God in the Garden”, we are introduced to
the New Leaf Superior, a genetically engineered potato. This is not the first of
its kind, for it is only one of the many foods that are products of an emergent
development here in the United States. Monsanto and other giant transnational
companies are carrying out a dangerous global experiment by introducing large
numbers of
genetically engineered foods into our diet. Genetic manipulations can
result in unanticipated harmful effects, and because genetically engineered
foods are not sufficiently tested, this experiment not only jeopardizes the
health of individuals, but also affects the natural flow of nature.

In the past few years the way we eat and live
our lives has become a extremely important topic, there has been massive
scares with such things such as CJD and issues with factory farming. However
there are so many terms thrown around about farming now a days it is hard to
keep up with what it all means.Before the 1950’s, "farming" was largely
applied to all agricultural activity whether it was practised on a prairie
or a peasant scale. However, since then, various new terms have evolved and
it may be useful to clarify, as much as possible, what is understood by
them. 1. Traditional farming This is the type of farming carried out
throughout the world for millennia past. It is characterised by
self-sufficiency, age-old traditions of husbandry and natural methods of
fertilizing (e.g. recycling animal and vegetable waste) weed and pest
control. On the whole, early, traditional farming was environmentally
friendly and sustainable but there were periods when mistakes were made and
over-use and deforestation resulted. Some desertification, as in the Sahara,
the Middle East, Peru and the US are examples of such early environmental
disasters. 2. Modern farming Modern farming, as we know it, began to
develop, particularly in the West, from the 1920’s. It is typified by a more
intensive use of land and buildings, mechanisation and the use of artificial
chemical fertilizers and weed and pest control. Labour was increasingly
being replaced by machines and chemicals. Specialisation in crops and
animals became the norm and a reliance built up on bought-in chemical and
processed inputs. This was farming becoming industrialised and large
companies developed to stimulate and supply its needs. 3. Factory farming In
the last half of the 20th Century certain areas of modern farming have
become even more intensive and farm animals are now being mass-produced in
industrial conditions. The most extreme example would be poultry where in
some units millions of birds are kept in small, individual cages. Pigs are
probably the next most intensively produced farm animal with units of
hundreds of thousands (and in the US, millions) housed in factory-like
buildings. Beef and other farm animals are also produced in large feed lots
and in slatted-floor housing. High-protein rations (including until
recently, meat and bone meal) artificial hormones and antibiotics are fed to
improve productivity. 4.Biotech farming This controversial type of farming
has developed mainly in the last 20 years. The technology is designed to
increase agricultural productivity by genetically engineering or
manipulating (GM ) genes in plants sometimes by adding animal genes. GM
crops have been developed to be resistant to specific herbicides and pests.
In one case seed was designed so that it could not germinate the following
year. Although millions of acres are grown it seems as if the AgBiotech
industry is in trouble. Governments are insisting on labelling or in some
cases even banning GM foods, farmers are angry as productivity and profit
targets have not been met and public and scientific distrust of the
technology is growing. 5. Sustainable farming This is a term that needs some
standardising. Organic and sustainable are often used interchangeably. Yet
organic can be unsustainable in certain circumstances, and sustainable need
not be organic. Sustainable farming as described by Prof. Pretty *seems to
be emerging as the standard explanation of the term. In many respects, as he
describes it, it is similar to organic farming. Sustainable agriculture
encourages the recycling of natural wastes as manures and encourages
appropriate technology, such as surface cultivation, rather than deep
ploughing. It is different from organic farming in that it doesn’t exclude
artificial fertilisers and chemicals but attempts instead to optimise their
use. Recent reports show that thousands of communities and millions of acres
are now involved and are showing dramatic increases in productivity combined
with increasing soil fertility and an improved environment. * Prof.Jules
Pretty is Director of the Centre for Environment and Society at the Univ. of
Essex. A world expert on sustainable agriculture he is the author of a
world-wide report launched in Jan ’01. 6. Biointensive Farming Biointensive
gardening, sometimes called mini-farming is a combination of Irish lazy-bed,
19th C. French raised-bed, and Chinese traditional methods of farming. It
claims enormous outputs from a very small area - enough to feed a family
from a few hundred square feet - whilst building uo the soi.More about this
method developed by American, John Jeavon, based on the work of English
gardener, Alan Chadwick at; www.growbiointensive.org 7. Vegan organic
farming www.veganvillage.co.uk Promotes vegan organic farming.. "Can’t feed
two populations, animals and people…" they argue. Vegans criticise
extensive, organic, animal husbandry systems as, "disastrous" and
"irresponsible". It takes, they say, 85% of UK farmland to feed the one
billion animals slaughtered there each year. 8. Biodynamic farming Basically
the same as organic farming but with a more esoteric and philosophical base.
Part of the anthroposophic teaching of Austrian, Rudolf Steiner, it purports
to help the health-giving forces of nature with special methods and
preparations. Steiner admirably emphasised the absurdity of agricultural
economics being determined by people who have never farmed.

times as a response to what was perceived to be the polluting of our food
supply by modern and factory farming methods and the ensuing degradation of
the environment with chemical and other by-products of the industry.
