Genetically Modified Crops Bring Predators!











I live on genetically modified food, and you do you, and we both have been for decades. Surely you don't think cows, chickens, sheep, corn, soy and apples are found in the wild producing at the rate they do on the farm?

Here's the thing that the fear mongers will not tell you: genetically modified foods boost production and therefore take pressure off of wild lands so forest does not have to fall to field, and field does not have to fall to factory.

Here's another thing the fear monkeys will not tell you: genetically modified foods allow predators to come back to out fields... predators like the lady bugs, spiders, lacewings, and praying manti. Why is that a bad thing? Answer: It's not!

But don't believe me. Discover magazine tells the story:

In China, with Bt cotton reducing the need for insecticides, pest-eating bugs have rebounded and brought natural pest control with them.

China’s genetically modified cotton is not new. Farmers used to spray their cotton with a protein, naturally produced by the Bacillus thuringiensis (Bt) bacteria, which is toxic to certain insects. As research into genetically modified crops advanced, scientists implanted the cotton itself with the Bt genes that code for production of the insect toxin, creating so-called “Bt cotton” and alleviating the need for the sprayed insecticide. Since China approved its use in 1997, Bt cotton has proved itself particularly effective against the cotton bollworm moth, reducing the costs and side effects of spraying pesticides, but it has also decreased the number of non-pest insects compared with organic fields.
