Bob is absolutely full of shit.
He is speaking with the air of authority on something he knows less than nothing about. That is, he has so much misinformation that he would actually be better off being completely ignorant.
Let's review the errors.
Selective breeding is NOT the same thing as genetic engineering. Genetic engineering involves using viruses (or other small carriers, such as needles) to modify a species using genetic material from a completely different species. In other words, two species that could NEVER breed in the wild can have materials combined. Viruses can move genetic material around in the wild "naturally," but, in multicellular organisms, this is an incredibly rare event that has only been theorized to have occured. In other words, this is NOT a natural event. In fact, you take genetic traits from plants and fungi and add them to animals. The organisms don't even have to be in the same kingdom.
Bob implied that this was only turning on and off existing traits.
In this, Bob is a liar.*
In comparison to crossbreeding, Bob calls using genetic engineering, "simplifying." By his bullshit logic, invasive surgery is the same thing as taking an herbal supplement.
And oh, let's not hear the "it all exists in nature" canard from some of the posters. Cyanide is naturally occuring -- I invite you to try some. The fact of the matter is, a protein that is excellent in corn won't necessarily be healthy in a trout. Biological systems are exceptionally complex -- they are likely the most complex thing known to man -- and extensive testing would be needed to be certain the chimeric animal is healthy and safe to eat -- testing that Monsanto and the like are dedicated to avoiding.
By the way, the relevant term here is chimera, NOT a hybrid Bob -- and if you don't know what a chimera is, you shouldn't even be in this discussion. Seriously, this is like discussing the Middle East without knowing what Jew, Arab, oil, and the U.S. mean.
But back to that earlier point, it is not the mere existence of a biological agent that makes it "natural," but its relationship with the organism. I can assure you that an octopus contains plenty of chemicals that, if placed in the human bloodstream, would sicken it, and vice-versa. Saying that something is "natural" because it's found in nature is like claiming it's okay to stab you in the head with an icicle. Water is natural, after all, and you're full of it already, right?
It gets worse. The problem with genetic engineering -- which Bob doesn't even understand -- is that it is being used without proper controls and with complete disregard to environmental laws and human saftey. Monsanto, the biggest and most well-known perpetrator, made its fortune by doing the following:
a) Invent a highly toxic weed killer.
b) Genetically modify seeds with material outside the seeds' species to resist the weed killing toxin.
c) Modify the seeds further for other uses.
d) Fail to test the food on animals -- or test the food badly, obscuring animal harm such as increased rate of cancer. (Yep, they'll lie about their own results.)
e) Sell the seed to farmers where the plants will interbreed with wild species, contaminating them.
And the real doozy:
f) If some of Monsanto's seeds get onto your property and you've refused to buy their seed, they will claim your ENTIRE FARM as their own and take the plants you developed via decades of actual cross-breeding, patent the plants, and steal your livelhood.
I'm not kidding. They did this to farmers in Canada and are pulling the same crap in India.
Oh, by the way: if you're in the third world, they'll refuse to let you save your seeds -- you know, what farmers have done for over 20 thousand years. That way you have to buy from them ever year. And they jack the price up. Not that you needed to buy their seed before they started polluting your crops with their seeds.
Needless to say, contamination of some of the oldest crops of mankind could lead to some pretty serious devastation. Monsanto and similar companies are using the entire planet as a laboratory and have no experimental controls. (And again, if you don't know what a scientific control is, you have no business saying anything about genetic engineering. Just to be sure, I'm not saying you shouldn't talk about this: you should. You should look up your terms first, however -- and not spew a bunch of poisonous lies on a popular media site while ridiculing hundreds of millions of people fighting to preserve their lives and jobs.)
It is not genetic engineering to improve crops. It's genetic engineering to exploit the trademark system, a legal system that the framers of the Constitution never expected to be employed as we do today. It is supposed to be illegal to patent living things; Monsanto's bribes changed that.
And, oh, Bob -- that carrot? The one you thought you were so clever about? Yeah, we know it was genetically engineered due to activists telling us. It wasn't mentioned in the supermarket. In fact, Monsanto and its allies work hard to obscure all genetic engineering information and hope to make its disclosure illegal. This is despite the fact that some of their additions can trigger allergic reactions in humans.
So, if you're allergic to peanuts, imagine it being illegal to label something as containing peanut products. That's you're future.
Seriously, Bob, that carrot gag did nothing to ridicule your target and simply made you look like an ass.
Hell, even his non-science discussion is a doughy pantload. Frankenstein's lack of scientific credentials in the novel was basically irrelevant since accredidation didn't mean much in the 19th century -- but, zounds, it was a big deal in the 20th, hence the change to the movie.
You'd think he'd know that, being a movie critic.
*The vehemence of this reply is due to the fact that Bob was contemptuous of people who have a valid, important concern with the state of the FDA. In short, Bob was belittling people who are working their asses off to save lives and livelihoods in the face of ridiculously irresponsible and, frankly, antiscientific mismanagement. And he did so using out-and-out lies, some of which parallel the lies used by the industries breaking the laws and bribing congress as we speak. I call him a liar because of his confidence; he made blanket, untrue declarations with the intent to persuade.
