I love meat! I love vegetables! But I prefer them to be derived from natural processes. Nobody can tell me with any certainty that some artificial fertilizer or hormone or genetic modification won't prove to be very bad for me in the long run.
None of us would be surprised if tomorrow morning a study proves some new chemical or genetic modification process to cause cancer, or worse! Maybe more of the cancer or heart disease seen today are attributable to that than anyone has (yet) noticed. Maybe some kind of superbug will evolve under the conditions created so artificially.
Now, mother nature's way (even with natural selection, human influenced breeding, etc.) won't gum up nature's finely tuned clockworks as quickly or unpredictably as "mostly random" guesses by "mostly ignorant of what they're REALLY doing in such a complex system" scientists. It's a field of science they're only barely scratching the surface of. It would be like randomly injecting bytes into a huge executable and running it to see if it works. Even with the help of an ML monitor, debugger (roughly equivalent to methods current GMO technology offers) you KNOW as well as I do that it would be nearly impossible to predict the outcome, or even notice the potential for a "fatal crash" in the unknown future.
I also grew up as a rancher and farmer, and we all know how those guys suffered due to the likes of Monsanto and others' GMO seeds pushing others out of the market, but making it impossible to plant their own the next year. Most families I used to know who had been farming and ranching since the 1800s have been pushed out of business now. But you can't tell me we have lower demand for the food they used to produce. The land isn't even used for farming in most cases, just wasted.
Sure, some of these things save starving people's lives, but so could almost rotten food. I'm more content spending a little more for food I can trust, and keeping the *real* farmers and ranchers in business. Thank you very much.
