There is always a certain percentage of people who are skeptical about any new technology. We are routinely being warned about various things that are supposed to be extremely harmful to our health. Examples:
1. Swine flu, bird flu, Asian flu---These were supposed to become pandemics and wipe out billions of people.
2. Y2K---The computers were all supposed to crash at the turn of the century, and life as we know it was supposed to cease.
3. Global cooling---in the 70's, we were being warned about the beginning of another "ice age". Never happened.
4. When I was in elementary school, we had "atomic bomb" drills, where we were instructed to cover our heads and get under our desks.
5. Artificial sweeteners---Every one of them is supposed to cause a malady of some kind.
6. Ozone layer---The ozone layer above the earth is being depleted, which will cause all kinds of trouble.
7. Global warming---May or may not be true, but in my many years of life, I have seen hot summers, cool summers, early falls and springs, late falls and springs, cold winters, warmer than usual winters (I like them best), wet years, dry years, snowy winters, open winters, normal years, etc. Add them all up, and I'd bet that there is no year that is not "abnormal" in some way.
What I'm trying to convey to everyone is that we humans always seem to be in the process of being warned about some kind of crisis that is supposed to be catastrophic. Most of the time these things are overblown, and don't warrant the amount of resources that are expended to nullify them.
Perhaps I'm just too old and set in my ways to worry about such things, but it sure has made my life more enjoyable since I learned to be skeptical about all these crises. I feel the same way about these roundup scares. My poultry has been free ranging over our land that has been sprayed with roundup for over a decade. None of these birds have shown any ill effects. We have lots of frogs and toads, and they have not shown any problems either. Neither have we noticed any "super weeds".
