The notion of reduction in pesticide use tonnage is a temporary effect and results in negatives akin to the effect of antibacterial soap. Over time you reduce the effectiveness of pesticides by increasing the resistance of pests. Same goes with herbicides. This effect has been well documented. You also create a situation where genetically identical and thus totally open to whatever weakness or environmental pressure crops are taking a huge if not total share of the local gene pool through cross pollination and more alarmingly through strong arming of producers. Which of course results in a rather scary situation where crops man depends on can be wiped out easily without the benefit of variation, which is of course the first line of defense in a species ability to resist a threat.
This isn't about some beneficent company desiring to "feed the world" or whatever...this is about agribusiness desiring to corner the market and control, with government support, both ends of the crop production cycle in a way ultimately dangerous to the health and food security of consumers. And no, obviously its not because the crops themselves are necessarily directly dangerous to consume (I'm not sure who came up with that idiocy...though, of course...we simply can't know for sure. I personally can't think of any reason why they'd be dangerous to consume.)...but because the gene pool is made far shallower and more open to eventual attack, and because frankly this an an extremely immature technology and we just can't know yet what the eventual ecological consequences might be. Just the realization that genes don't code for single proteins should cast some serious doubt on some of these practices, considering that a lot of the fundamentals behind some of these organisms are still based on the outdated theories from decades past that are based on the opposite.
This is clearly an ideological issue more than a scientific one to most people on the right...and as such can't be rationally debated. Conflating this with anti-vaccine movements it just such a mind numbingly ignorant....eh. Whatever. Internet.
Sad thing is that Jackson County is going to wind up cross pollinated no matter what it does.
