Yes, it is so. Consider that corn was modified to be more resilient but its pollen may be compatible with nearby plants. Hybridization of transgenics with local flora may have unintended and far-reaching consequences. That's why the "Terminator" traits are typically outlawed. No one (eh...citation needed) desires a world where growing the food requires a proprietary compound. I doubt a civilization with a food supply like that could remain stable.

However! I read an interesting study that claimed Bt transgenics are better for food production & the environment because they kill crop pests but the carnivorous field fauna (spiders, horseflies, etc.) flourish with humankind's helping hand.

Whereas I typically purchase non-GMO foods, this revelation caused me to question, and to become ambivalent. No doubt pests would tolerate Bt with time, but in humans Bt is a non-toxic pesticide, and the germlines of the crop pests would probably never recover from the trait's proliferation. At the same time, the carnivorous "worker arthropods" which eat the crop pests would also experience a huge acceleration in their development.

Directed breeding in animals is an issue which has a tighter grip on my heart--some of the stuff that's been done to dogs and cats to "get them to look a certain way" is really messed up. Maybe some look at the fields the same way.

I do not know. It is not my choice. I am glad for that.
