Uh Oh; The Bugs Are Eating Those "Pest Killing" Crops

Two research teams in England and Venezuela have discovered something
alarming about the new genetically modified crops filled with
insecticide. The insects not only eat them, they seem to thrive on
them.

Scientists at Imperial college in London and the Universidad Simon
Rodrigues in Caracas found that the insects that the chemical additive
was supposed to kill were not only feeding on the poison, but the
stuff seems to help them thrive.

That the biotech companies added genes from a naturally occurring
poison, Bacillus thuringiensis (Bt), which is widely used as a
pesticide by organic farmers, means that the mutation by insects to
survive the poison is a potential threat to the organic farming
industry.

Environmentalists believe the resistance developed quickly because the
insects are constantly exposed to the chemical in the plants, instead
of being subjected to occasional spraying.

This is bad news for not only the struggling agricultural industry but
for over 6 billion world food consumers as well. With the world
population exploding and the instability of weather because of global
warming, world agriculture is in danger of falling short of producing
enough food for everybody.

The GMO experimentation with Bt fell under fierce criticism by growers
world-wide who warned that the excessive use of the chemical would
eventually generate stronger chemical-resistant pests. Not even the
strongest critics dreamed that the insects would be feeding and
thriving on the plants engineered with Bts.

But there is more bad news about those modified crops. Lots of it.

Prominent scientists from seven countries recently produced an
Independent Report on GM agricultural practices during a public
conference in London. The report, titled The Case for a GM-free
Sustainable World, called for a ban on GM crops.

The conclusions:

--GM crops failed to deliver the promised benefits. There have been
shown no increase in yields or a significant reduction in herbicide
and pesticide use. In fact the United States lost an estimated $12
billion over GM crops because of worldwide rejection of them.

--The GM crops are posing escalating problems on the farm. The group
found that transgenic lines are unstable. Triple herbicide-tolerant
volunteers and weeds have now emerged in North America, creating
severe problems for farmers who suddenly have no inexpensive solution
to weed and pest control. The fear is that superweeds and bt-resistant
pests have been created.

--Further extensive transgenic contamination, especially for corn,
seems to be unavoidable. It has been found in maize even in the remote
regions of Mexico. Tests showed that 32 out of 33 commercial seed
stocks in Canada, where GM corn is prohibited, were contaminated
anyway. Corn pollen remains airborne for hours and can be carried by
the winds for miles. Thus there can be no co-existence of GM and
non-GM crops.

--GM crops are not proven safe. In fact, its regulation was fatally
flawed from the start. The principle of "substantial equivalence," a
vague and ill-defined rule, gave companies like Monsanto complete
license in claiming GM products equal and as safe as non-GM.

--Dangerous gene products are incorporated into the food crops. For
example, Bt proteins, added to 25 percent of all GM crops, are harmful
to many non-target insects, and some are potent allergens for humans
and other mammals.

--GM foods are increasingly used to produce pharmaceuticals and drugs.
These include cytokines, known to suppress the immune system and are
linked to dementia, neurotoxicity and mood swings; vaccines and viral
sequences like as the 'spike' protein gene of the pig coronavirus, in
the same family as the SARS virus; and glycoprotein gene gp120 of the
AIDS virus that could interfere with the immune system. The fear is
that this last gene could recombine with viruses and bacteria to
generate new and unpredictable pathogens.

--Crops engineered with suicide genes for male sterility, promoted as
a means of preventing the spread of transgenes, actually spread both
male sterility and herbicide tolerance traits via pollen.

--Broad-spectrum herbicides are found to be highly toxic to humans and
other species of animals. Glufosinate ammonium and glyphosate, used
with herbicide tolerant GM crops that currently account for 75% of all
GM crops worldwide, are both systemic metabolic poisons. Glufosinate
ammonium is linked to neurological, respiratory, gastrointestinal and
haematological toxicities, and birth defects in humans and mammals;
also toxic to butterflies and a number of beneficial insects.
Glyphosate is the most frequent cause of complaints and poisoning in
the UK. Its exposure nearly doubled the risk of late spontaneous
abortion. Children born to users of glyphosate had elevated
neurobehavioral defects. It caused cell division dysfunction that may
be linked to human cancers.

The report warns that genetic tampering with foods may be
inadvertently creating super-viruses and bacteria that could spark
unstoppable world-wide plagues. "Newer techniques, such as DNA
shuffling, allow geneticists to create in a matter of minutes in the
laboratory millions of recombinant viruses that have never existed in
billions of years of evolution," the report warns.

The report concludes: "sufficient evidence has emerged to raise
serious safety concerns, that if ignored could result in irreversible
damage to health and the environment."

Ur, do you suppose these might be the SAME pest species whose natural
numbers used to be thinned by natural encounters with Bt toxin in the
environment and now will never be held in check again by those natural
bug poisons?

I think gallows are appropriate discussion topic for people who rushed
to market something without full-scale environmental issues discussions
with the world's INDEPENDENT ecologists. This was PREDICTED and WARNED
about years ago -- I know my comments are on file in archives to be
introduced in court trials of environmental criminals -- so they can't
say "nobody had any idea this could happen".
