A New and Alarming Reason Why GM Crops Are A Very Bad Idea...

I've devoted a number of pages to studies warning you about all the healthy reasons you and your family should be staying away from genetically modified foods, even though it's getting harder to do with crops hitting the billion mark.

If that isn't bad enough, consider this: A mistake in "engineered" crops growing too close together could breed insects that develop a resistance to all the proteins meant to kill them. Scientists and critics have been concerned the widespread use of Bacillus thuringiensis (Bt), a soil bacterium whose genes are inserted into crop plants (maize, cotton), could create an environment in which insects develop a resistance.

Although no crop failures or insect resistance have been reported, researchers discovered the concurrent use of single- and dual-gene Bt plants can put the dual-gene plants at risk if single-gene plants are deployed in the same area simultaneously based on lab tests. In fact, cabbage loopers -- a moth whose larvae feed on plants in the cabbage family -- have already shown resistance to Bt sprays in commercial greenhouses.

Considering the amount of GM crop coverage worldwide -- more than 85 million acres -- it isn't a stretch to imagine the kind of devastation that could happen to our food supplies if toxin-resistant insects evolve and multiply. All the more reason for you to be ever vigilant about where your foods come from.

Just a reminder, the worst place to find them is your neighborhood grocery store, considering you have a 75 percent chance of choosing a processed food product made from GM ingredients there.
