Fact Sheet on Genetically Engineered Foods & Crops
by Brian Tokar

What is Biotechnology?

Biotechnology involves the simulation in a laboratory or industrial setting
of basic life processes at the cellular and molecular level.1 It is also a
growing industry, through which a small number of agrochemical and
pharmaceutical companies are seeking to reshape agriculture, medicine,
animal husbandry, and perhaps the future of life on earth. Biotechnology
encompasses such emerging technologies as genetic engineering, cloning of
animals, enzyme engineering and test-tube breeding of animals and humans.2

Effects on the environment

Over 3000 varieties of genetically engineered plants, animals and bacteria
have been developed and field tested in the U.S.3 Genetically engineered
plants resist high doses of herbicides, manufacture insecticidal toxins,
resist viruses, ripen more slowly or more uniformly, and display altered
chemical compositions.

These plants can become invasive weeds, or pass on to native plants
combinations of genetic traits not previously found in nature.4 Virus
genes added to plant cells can create new strains of plant viruses.5
Pesticide-secreting crops, such as Monsanto's "New Leaf" potatoes are
likely to impair beneficial insects as well as common crop "pests."6 The
most common type of genetically engineered crops are those designed to
resist toxic herbicides such as Monsanto's Roundup (glyphosate) and Rhone
Poulenc's Buctril (bromoxynil). Biotech companies claim to have grown some
30 million acres of genetically engineered crops in the U.S. in 1997, with
unknown environmental consequences.7 Researchers in Germany have shown
that genetically altered bacteria and viruses can persist in water, soil
and even clothing.8

Fish have also become frequent subjects of genetic engineering research,
with efforts in the U.S., China and elsewhere to make commercially
important fish species grow larger and resist environmental changes.9
Human growth hormone genes have been added to goldfish, trout genes to
carp, and cold-resistance genes from flounder have been added to Atlantic
Salmon on an experimental basis. Ecologists are already concerned about
"genetic drift" from farm-raised fish populations into the wild;
biotechnology only heightens this concern. In a further assault on
wildlife, European officials have been loading bait for wild foxes with a
genetically engineered rabies protein that stimulates their immunity, but
is also closely related to smallpox and a number of other animal poxes.10
The environmental consequences of increasingly frequent releases of
genetically engineered bacteria, mites and other organisms have barely
begun to be studied.11

Effects on health

There is serious cause for alarm about the effects of biotech products on
both humans and animals:

* Monsanto's "Posilac" brand of bovine growth hormone (rBGH) is associated
with high incidence of udder infections, internal bleeding, stress-related
wieght loss and severe reproductive disorders in cows.12 Cows injected
with rBGH secrete high levels of IGF-1, a hormone that is tied to increased
growth of cancer cells.13 Pigs altered to produce human growth hormone for
leaner meat have underdeveloped muscles and often cannot even stand up.

* Plants containing genes from other species are likely to transmit
allergens or toxic alkaloids, and can have altered nutritional
compositions.14 Herbicide-tolerant crops will likely lead to increased use
of toxic herbicides in agriculture, contrary to industry claims.

* Nearly all genetically engineered cells contain antibiotic resistance
genes, incorporated as a "genetic marker" to make it easier to pick out
these cells in the laboratory.15 These antibiotic resistance genes can be
passed on to numerous strains of bacteria, including disease-causing
bacteria.

* The cloning of sheep and other animals is being advanced by companies in
Europe and the U.S. that seek to turn animals into "bioreactors" for the
production of drugs and other useful proteins.16

Biotechnology in forestry

Biotechnology research in trees generally lags behind other areas, but
multinational corporations and university and government laboratories are
seeking to develop genetically altered nursery stock that grows faster,
resists insects, viruses, frost or drought, and produces wood that is
easier to process into lumber or pulp. As with agricultural products,
research on the possible environmental consequences of genetically
engineered tree plantations lags far behind the development of the
engineered varieties.

The Canadian Forest Service (CFS), which is actively field testing
genetically altered varieties of poplar, spruce and larch (including the
introduction of various corn and wheat genes) acknowledges that such
varieties should be made sterile to minimize the effect on native forests,
but has not committed to this in practice. The CFS is also actively
pursuing biotechnology research on several insect viruses, and on
herbicides derived from fungi.17

Trees raised for the timber industry's "reforestation" projects are
increasingly produced from laboratory cell cultures rather than from seeds.
This results in large plantations of trees that are genetically uniform,
and thus are more susceptible to various genetic manipulations. However,
they are also more susceptible to widespread outbreaks of disease.

Researchers at Oregon State University have demonstrated that genetically
engineered bacteria developed to digest crop wastes can severely alter the
properties of soils. They encourage the spread of root-feeding nematodes
and suppress populations of beneficial soil fungi, which impart disease
resistance and aid metabolism in many native species, including old-growth
trees.18

The Department of the Interior reached a secret deal with a San Diego-based
biotech firm called Diversa, to allow them to study and patent
heat-resistant bacteria from deep within the geysers of Yellowstone
National Park. A recent lawsuit by two public interest groups seeks the
withdrawal of this "bioprospecting" contract, as it violates the integrity
of the National Parks as a public trust.19
