Agreed. With any new technology, we should have learned caution by now. Medicine is constantly changing. As is all science.
Think of the guy who developed String Theory - he was laughed out of the scientific community in the 50s or 60s. After his death, the theory was recognized as valid, and he is now lauded. That is the nature of science. It's being curious! What is the most important question in science? It is Why?
Yes, as I see it, the biggest concerns (for environmentalists of every stripe) are with the prevalence of corn sugars, soy and other products - even without the GMO discussion, this is a serious issue, because it's not good nutrition. Chemicals are not good for us .. antibiotic resistance is a good example. It's become a big problem, since the baby boomers (my generation) was the first to consume mostly antibiotic-fed livestock. It's just 'something to think about'. I can't eat commercial eggs - I am allergic to cephalosporins - which is the antibiotic fed to chickens, and gets concentrated in the eggs. No turkey, either. Now, this is what the alergy specialist confirmed when I got tested for penicillin allergy (a close cousin to cephalosporins - if the spelling is wrong, one drug is called "Keflex").
So, proof positive that we are not aware of what these changes in our food may do to future generations, just as medicine did not know that viruses existed until very recent history. It's science - progressing, and a "Candle in the Dark".
Caution is the word I would use. I really dislike "fear factor" tactics, whether they are used by the left or the right... whether it's about terror or food activists gone rampant. I think we would agree on that, and look forward to more lively discussion in the future. : )) Perhaps we have similar leanings, I am just an a somwhat opinionated, old, hippie anarchist, and that can be a bit challenging to deal with, at times. Ayup.
