It depends. If your open pollinated seed produced $200 worth of corn per acre, and purchased hybrid corn produced $260 of corn per acre, and the hybrid corn seed cost $10 per acre of corn planted, you're actually losing money to use open pollinated seed.
(Numbers used for dramatic purposes. Actual numbers would include cost of spraying for weeds and plowing for non-roundup ready seeds, plus the decreased yield, plus other stuff.)
Round up ready crops are causing round up resistant weeds, this is a fact.
Errr. No. It's not the GMO crops, it's the use of roundup. And it's the use of roundup - including its generic alternatives - by anyone. Round up is NOT in the GMO round up ready corn or other crops, until the crop has been sprayed by the farmer.
Use of any chemical - by farmer, gardener, animal or plant - creates an incentive for another organism to become resistant to it. And some weeds (including pig weed, which most everyone already hated a good bit) are showing signs of roundup resistance. Still shovel-liable.
Another fact is that, due to the monoculture of weed free fields, we are losing habitat for valuable and endangered species of birds and insects. ... Because a field of round-ready corn or soy has so many fewer weeds than traditionally planted soy or corn, there are less native weeds for butterflies, pollinators, predatory insects and birds.
Hogwash. Firstly, the weeds would be dealt with in SOME manner - either roundup, or a much nastier chemical, or extra cultivation with a petroleum fueled tractor, or some poor soul hoeing the crop. Claiming that native weeds in a crop field were significant supports for, well, much of anything - I would REALLY love to see the study showing this.
Secondly, an increase in weeds in the field increases the amount of weeds in the crop when harvested - which includes toxic seeds mixed into the wheat and corn and ground into bread for people and feed for geese. Not a good thing by me.
Thirdly - Roundup ready increases yields. Increased yields means less acres need to be planted to produce the same amount of bread and geese grain. This means less wilderness land needs to get plowed up to be planted for grains.
Monarch butterflies have dropped drastically in number since the increase in GMO crops.
