Before I start to tell you (about what
I have been reading) —I want to talk about GMO's (Genetical
Modified Organisms)
There are 3 MAJOR kinds of GMO's.
Horizontal(good) and Vertical (Less good), and Chimera GMO's
(horrid!)
Horizontal GMO's have been around for
centuries. They are common even, in both plants and animals.
Start with seeds, plant them. When you
harvest them, save the best—with characteristic A
Plant the best. Save the best again
–only now select for characteristic A and B.
Repeat, and repeat, time and time
again.
Look for better yields, or stronger
(shorter) stalks, faster growing time (less likely to be lost to
frost or late season rains.) Over time, these efforts will result in
a GMO. Every time you grow and select, you are selection for a GMO of
the original crop. Over a thousand (or more years) you can create new
organisms.
As time moved on, farmers learned how
to IMPROVE by intentionally (controlled) cross pollinating one kind
of plant (be it peas, or wheat or what ever) with other plants (short
peas with tall peas, or plump peas with drought resistant peas, or
any sort of pea, with another sort).
INTENTIONALLY cross pollinated seeds
are technically GMO's!
We have a name for these horizontal
GMO's—HYBRIDS. They, too, have been around for centuries.
In animals, IN-LINE breeding is another
sort of GMO—since naturally, animals avoid mating with siblings
(or parents)But In-Line breeding is still Horizontal.
Vertical cross breeding has been going
on for a while, too. They are not uncommon at all. It most often
occurs between somewhat related animals. Crosses between horses and
donkeys (similar animals) result in MULES.
Mules are called mules because one
meaning of the word mule is “STERILE”, and Vertical cross
breeding MOST often results in sterile animals (and plants!) Mules
are simple vertical GMO's.--But each cross breeding is the end of the line.
There ARE other vertical cross breeds
(dogs with wolfs, or dogs with coyotes ) Some times these cross
breeds are viable (that is, they aren't sterile!) They can mate
successfully with other like themselves, or with dogs, or with
wolves)--but this is Uncommon.
Plants have been vertically crossed
with other (related plants) too.
Farmers in the fields have made 2
different kinds of plants cross breed—there is a new
grain-TRICICAL—which is a cross between wheat and rye.. (Wheat and
rye are both grain/grasses, but are as different as a donkey from a
horse.)--and at first, most of this new grain was sterile (the seeds
would not germinate.) But over time, a viable version emerged.
There have been other vertical crosses
- Some occur naturally, some helped out by controlled pollination)
citrus fruits, are one common example. Crosses between oranges and
grapefruits, or oranges and tangerines, exist (and are popular)
Most often the results are sterile,(the seeds, if any are produced,
are sterile) The plants can only be propagated by grafting.
SO—GMO's –whether Horizontal or
Vertical are not new, and not entirely evil.
But things have changed. NOW Vertical
cross breeding is not done with real live animals, or in the field,
or by nature, or with farmers hand pollinated plants to create
crosses. It's done in a lab, by intentionally mixing genes from
totally different organisms.
Now, companies (READ MONSANTO, for one)
are making vertical Chimera GMO's They are crossing plants with
animals. Potatoes with BT (a bacteria) or Corn with another bacteria.
Goats with spiders. Mice with humans (to produce human insulin)
These GMO's are not natural—( it is possible, that over the course of many thousand of years, some
of the chimera type crosses could occur naturally. (but it would be extremely
rare)--And it's likely the natural chimeras would be sterile. There
are certain viruses that can create Chimeras—but these rarely
infect humans.
Modern VERTICAL chimera GMO's are, as
the name chimera suggests, MONSTERS. They are not natural, and if in
a rare circumstance, they did occur, the result would be a sterile
mule.
The food we are eating (these
chimeraGMO's ) have been designed to be viable.
BUT—worse than being viable, —the
process that make chimera GMO's possible,--is a process that makes
the chimera plant DNA (or other DNA) less resistant to 'infection”
by other (foreign DNA) These new Chimera GMO's have a tendency to
share DNA—all on there own. The tendency (rare in nature) to
create chimera GMO's has been bred into the plant.
The chimera GMO DNA is designed to be
less resistant (even one could say EAGER) to swap its DNA with
others—be they other plants, or insects, bacteria, or for all we
know, animals (like our selves!)
Every time you eat a Chimera GMO, you
risk YOUR DNA.
Since the Chimera GMO “wants” to
swap its DNA with yours--That is-- the chimera wants to add HUMAN
DNA to itself, and it can also transfer it's DNA into yours. Maybe
not frequently—but if you eat food ever day, (3 times a day), every
year, you are taking over 1000 chances--Every year. Over the course
of a lifetime, MILLIONS of chances. Chimera GMO's are everywhere!
Every meal is full of them. Even if the chance of Chimera GMO
infection you is small with each exposure, you are subjecting
yourself to thousand and thousands of exposures.
Take Corn.
90% of US crop is Chimers GMO corn.
(and corn? You might not eat visible corn (on the cob, or as corn
flakes) but on average, 40% of caloric intake is corn. In corn
syrup, in HFCS, in corn starch or modified corn starch, in vegetable
protein, and hundreds of other food “Products”.
Soy? Even worse! 99% of US crop of soy
is Chimera GMO. And again, soy is hidden in many food—as an
emulsifier (soy lecithin,) or 'vegetable oil” or vegetable protein,
--Soy is every where. You can skip the soy sauce, and still eat lots
of soy every day.
The US potato crop is an other Chimera
GMO. Every french fry, every potato chip is a gamble.
These are just the big 3. Chimera GMO
foods are the foods we eat, every meal, every day.
And because of the Chimera GMO tendency
to swap genes, Chickens that eat Chimera GMO corn, become Chimera GMO
Chickens. Same too, for cattle, or for pigs. Slowly but surely,
Chimera GMO is working its way into every organism. We are becoming
less ourselves, and more and more monsters.
And no one knows what kind of monsters
we will become. There is some evidence that Chimera GMO's will turn
us all into MULES(sterile). Perhaps not in one generation, or two.
(Perhaps never.) But right now, no one knows for sure.
Non-GMO (OK, hybrid) foods crops are
becoming Chimera GMO –YOU can plant non GMO corn, but if your
neighbor plants Chimera GMO corn, it's likely a percent of your crop
will become INFECTED with Chimera GMO DNA via natural cross
pollination. . No crop is save.
We all know the expression, YOU ARE
What YOU EAT—Every day, in every way, as we eat, we are becoming
less of our selves, and more of a Chimera. A scary thought.
Tomorrow I will review a book about a
scientist who's life work is creating GMO's—the good old fashioned
kind—Hybrids. There is the occasional Vertical GMO (simple cross
breeding of similar organism—as has occurred with citrus fruit)
involved, too, At the same time, he works very hard to save the
simple plants that created the hybrids. Saving pure DNA examples of
plants is almost as much as his mission as is creating hybrids.
It is a fascinating book—but
understand what he does, why he does it, and how it does it, is
essential.
Other wise, you just might think him to
be a GMO monster maker, too.

Wow! That was so fabulous! DH read it, too.
I'm linking back to this post in my side bar under the tomato plant button. Thank you for sharing this.
And, Welcome back. I've missed you!
I'm as horrified as anyone by Monsanto--maybe more horrified, because I worked in the molecular genetics field, motivated by a desire to help agriculture control pests through biological control rather than toxic pesticides.
However, chimeric genetic modification exists in nature, and need not be the train wreck agribusiness has made. Bacterial species are constantly swapping genes between species via plasmids. They are able to adapt to changes in their environment by getting new metabolic processes through gene exchange.
Like selective breeding and hybridization, it's a natural process. Its moral value depends on how it's used. (And I think we agree on not liking the way Monsanto is using it.)
