Dick, it's all too common for us to only consider how something immediately affects us. In the case of GMO, it really is more than immediate health risks... it is what is happening to the surrounding environment ... the unexpected consequences.

The most compelling issue is the placement of genes into corn - a wind pollinated crop that has quirky genetics to begin with. How do you protect your non-GMO corn from being fertilized/contaminated by the farmer a quarter mile down the road. The seed producers have sued farmers who used their "contaminated" seed corn for the next year's planting - claiming that the farmer was depriving the company of their proper payment.

Some genes allow the use of pesticides that couldn't be used on the crop before, while others insert genes that may actually increase resistence in target pest populations.

Organic farmers have issues with using the Bt gene, one of the few pest controls that meet organic standards when using the original baterium, in such a widespread fashion that threatens to increase the likelihood of resistent pest populations. Remember - the rat race of "resistence" is all part of evolution and natural selection.

If increased pesticide use causes increased mortality in bees and other pollenators, I don't care if it doesn't affect my immediate health. It's screwing up the rest of my envirnment that I do care about.

We improved the sanitation in cities, which did improve human health... at the expense of the water bodies that ended up taking in the waste. Now we have cleaner city streets... but polluted water bodies that can't support aquatic/marine life the way they did before.

Everything has a cost... the smart thing is to figure out that cost BEFORE committing yourself to a course of action.
