I've listed it like 3 times now. 1) That "harmful" GMO corn only fit for cattle was getting into the human food supply.
...
The real issue is that the GMO is suitable for direct human consumption while the previously used cattle feed is not. I thought the real issue was that cattle should not eat any food fit for human consumption. The big issue is that the farmers were using a human consumable to feed cattle. The GMO is an issue only when the GMO facilitates the replacement of grass by a food that can be directly eaten by a human being.
Cattle should be eating food fit only for cattle, such as grass. Grass can't be consumed by directly human beings, and grows largely without using up irreplaceable resources. So raising cattle on grass doesn't require as much human resources. Corn, on the other hand can be directly consumed by human beings. Humans have to exhaust a lot of resources
Part of this is thermodynamics. The more animal links between plants and human beings, the more resources wasted. Plants absorb a certain amount of free energy from the sun. This is true both for corn kernels and meadow grass. However, a human that eats a corn kernel uses a greater part of the free energy than when a humans eats a cow that eats the corn kernel. Calories from the sun are used up in keeping the cow alive.
The use of human food for raising cattle is environmentally bad. The GMO is bad ecologically only to the extent that it is good for human consumption.
Basically, this is the similar to the problem of ethanol for automobiles. Sure, the sugar from sugar cane and corn are replaceable resources in the sense that the sun and soil are replaceable. However, humans eat sugar from sugar cane and corn. There is only so much fertilizer and sun light one can get per years to raise the sugar cane and corn. So the ethanol fuel ends up being taken from humans.
Although GMOs can make ethanol fuel less expensive, the use of ethanol itself is not ecologically sound. The problem is not that the GMO is bad for direct consumption. The problem is that the use of ethanol fuel is ecologically bad.
What would be nice if one could use the cellulose in the crop to feed cattle or make ethanol fuel. Perhaps someone could develop a GMO crop that makes less cellulose and more sugar. Or best of all, a GMO bacterium that breaks down cellulose into ethanol. That would come with its own threats of course.
The other ecological issue is the use of insecticides on crops. GMOs are used to replace one insecticide by another. The farmer uses less of a highly toxic insecticide by replacing it with a lot of less toxic insecticide which the GMO is resistant to. A farmer that doesn't use the GMO can end up using a small amount of the highly toxic insecticide.
Taco Bell is not promising to avoid foods with a lot of insecticide. They aren't using 'organic' crops. They are not making a guarantee of avoiding insecticides, which can be measured using chemical techniques. Instead, they are promising to avoid the use of GMOs.
Does Taco Bell even have the means to make good their promise? How do they even know their product doesn't have a GMO? Could anyone sue them if there was a GMO in their food? Promises are rather cheap.
The suspicion that I have is that they are choosing to ban something that is not easy to monitor. The food that you eat at Taco Bells may have insecticides, antibiotics and hormones in it. Although it may cost, there are means to monitor these items. However, how other than the farmers word can a buyer know he is not using a GMO?
Taco Bell could do other things that would make their food safer. Taco Bell should avoid crops made with herbicides. The herbicides are dangerous to humans and wildlife. Taco Bell would be making a clearer statement if they said that their meat came from cattle which have not been treated with hormones or antibiotics.
The direct challenge to public health is the grease and sugar in food. The avoidance of GMO crops does not decrease the grease and sugar in food. They sell grease and sugar.
Hormones and antibiotics are known hazards in meat. Hormones have developmental effects on people. Antibiotics make cattle bacteria develop antibiotic resistance that can pass on to human pathogens. So why doesn't Taco Bell ban meat made with hormones and antibiotics?
I think this antiGMO campaign is smoke and mirrors. I notice that these other health issues have sort of disappeared from public view.
Okay, I will say it. The only long term solutions to most of these health concerns involve slowing down and reversing population growth. The antiGMO campaign is a red herring, raised with hormones and antibiotics.
