What
is Biotech?
Biological Technology, Biotech is a general "umbrella" term referring
to technologies that are applied to biological precessies. For purposes of this
paper it is the study and application of gene manipulation between and among
living organisms. (Genomics or marker assisted breeding, which does not involve
gene insertions, would be another; and cloning would be another). Basically,
we are looking at the altering of an organism's DNA by imposing, splicing or
inserting genetic material from another species or form of life (animal to plant,
human to animal, another plant family, etc.), or the altering of DNA by cutting
and "re-connecting" an organism's DNA into a different order. The
discipline for this is referred to as Genetic Engineering, or GE. It is little
known that the technique has been in use for over 20 years and that our lives
are touched and influenced by it every day.
How
is Genetic Modification done?
The nucleus of a cell, animal or plant, insect or bacteria or submicroscopic
microbe and fungi, contains the DNA which determines the function and characteristics
of that body of which it is a part. Genetic Engineering alters that DNA, either
by "inserting" some portion of a foreign DNA into that nucleus, thereby
initiating some change in the function and/or characteristic of the body (animal
or vegetable) of which it is a part, or removing some portion of the DNA so
that it reconnects with a changed purpose. (Organisms that have been "engineered"
in this way are known as Genetically Modified Organisms", or GMO's).
The "Vector": The method for doing the "insertion"
requires that the cell be "invaded" (cells do not like to be invaded
and they are programmed to reject foreign materials). Since we know that viruses
are capable of invading cells then why not use a virus to help us do the invading.
Makes a lot of sense, scientifically, and that is exactly what is used in the
most common method for genetic modification. The virus, in this case referred
to as a "Vector", has the desired genetic material attached to it
with the idea that the vector will invade the cell and permit the desired gene
to insert itself and bring about the desired modification. The common virus
used is Cauliflower Mosaic Virus.
The "Marker": Some way to determine the success of the modification
is now necessary. An additional material is placed into this mass that is being
inserted. This material, in this case called the "marker", is something
that can be tested for and, if present, indicates that the modification has
taken place successfully. The material used for the marker is an antibiotic.
The Modification: Not one, but usually several different antibiotics
are plugged into the cell along with the desired gene and the vector. When the
process is successful every cell in the resultant organism contains, to some
degree, the sought for characteristic as well as the antibiotic(s) and the virus.
The DNA string has been irreversibly altered, often containing more or less
chromosomes than the normal, natural organism.
Rate of Success: The rate of success is very low and it varies with the
individual application. Published figures indicate that the rate of success
is as good as one chance in fifty to as poor as one chance in thousands.
The "Gene Gun": Another technique used in commercial applications,
is the "Gene Gun". This device, developed (with funding from the Biotech
industries) at Cornell University, is actually a form of shotgun that fires
the material into the cell. The technique utilizes minute metal "shot"
which have had the genetic material, markers, etc., coated on the surface. The
shot are loaded into the gun and fired, at high velocity, into the cell. The
hope is that one of the coated shot pieces will penetrate the cell nucleus and
start the modification. The gun is loaded with literally thousands of these
minute metal shots, and the rate of accuracy is even lower than the common technique
of vectoring. It has been described as like using a slingshot to hurl a refrigerator
at a 10-story building and hoping it goes through the right window.
Some of the Myths About Biotech:
"GE is not new, it is simply selective breeding (hybridizing) speeded
up"
It can be agreed that GE is certainly a faster method of breeding something
new. It cannot be agreed that it is the same as developing a hybrid as an intentional
act, or through nature.
"Biotech
will feed the world"
The
truth is that over 30% of the food produced around the world is wasted, most
of it never reaching the dinner tables. There are over 3500 daily calories per
person available right now in grains alone. Add fruits and vegetables to that
and there are over 4 pounds of food available for each and every person on the
earth, every day. And that doesn't include meats. The countries where hunger
is the most severe are, most of them, exporting much of the food produced there
rather than giving it to the people who need it. One reason for this is that
these countries, most of them developing nations, need the revenue to pay off
the development loans to the wealthier nations. Also, most of the starving people
are too poor to even buy food. Some countries are so corrupt that any aid or
agricultural product is usurped and sold on the black market or kept for the
privileged few, never getting to the needy.
Proponents of GE point to the fact that the world population is increasing at
an alarming rate and, now at about 6 billion people, will reach 10 billion by
2050. The implied assumption in the Biotech industry claim is that there cannot
be enough food produced for that number of people unless we adopt GE foods.
Alternatives are being ignored for the sake of profit.
"GE foods will give higher yields (and cost less to produce, etc, etc.)"
The truth of this is that studies, like one done at the University of Nebraska,
show that yields are actually reduced. Side by side GE crops and those grown
either organically or conventionally prove that the non-GE crops out produce
the GE crops, acre for acre. It is a known fact that GE seeds are more expensive
than conventional seeds. In an attempt to build more appeal the Biotech companies
said it would result in maximization of yields on arable land and reduce the
pressure to use marginal land, thus contributing to wildlife habitat.
"GE foods are good for you"
"GE
foods will result in a reduction of the use of (toxic) chemicals in conventional
farming"
Studies over the several years that GE products have been grown show that there
has not been any reduction is the use of these chemicals. Rather, there has
been an increase in the application of many. Statistics published by our own
government agencies are proving this. We use over 8 billion pounds of just the
active ingredients in chemicals every year, 20 pounds for every man, woman and
child in this country
"GE
production is more efficient (in use of resources, etc.)"
There is no proof that this is anywhere near the realm of truth. As a matter
of fact, farmers who have been raising insect resistant varieties of some crops
are reporting a new phenomenon, a secondary wave of harmful insects, which appear
impervious to the genetically spliced in toxin, are further reducing their yields.
Also, certain so-called "super weeds" are cropping up due to unintended
cross pollination with the engineered resistant crops.
"GE
is a controlled, reliable process"
Scientists on both sides of the issue admit that the technique is far from reliable,
let alone predictable. The ratio of "successful" modification is extremely
low and, particularly in experiments to make "better" animals, many
gross and inhuman mutations have occurred. The description of the process that
was explained earlier pretty much verifies that it is an unpredictable, unreliable
process.
"GE
foods will be able to deliver vitamins and medicines, particularly important
in countries where known deficiencies are causing high mortality and illnesses"
The truth is that in the nearly 20 years that the Biotech research around the
world has been working on this, there is not one development, not one crop that
can successfully do this. Also, most of the medicines are (or need to be) administered
on an individual basis. Does a child require the dosage of an adult? What is
the risk to an elderly person or a pregnant woman, in a country where the literacy
rate is very low?
"GE
will give you more choices"
The only choices arising out of this so far is a proliferation of brand and
variety names, nothing one would consider a bonafide choice.
"GE
is safe"
Nothing in the eminent domain is a safe thing if it contains the slightest risk
of being used carelessly or for the wrong reasons. There is a played down concern
that some sociopath with the technology could do irreparable harm to people
or the environment. The more present threat; however, is that which has arisen
from the greed of the proponents. As for the resultant effect on our health
for our consumption of GE foods, there has been little independent testing.
The proponents, the large companies who have spent billions of dollars in development,
claim to have done testing and they claim that it is safe.
