Study: GM Crops, Touted For Pest Resistance, Rapidly Breed Resistant Pests
A new study, funded by the U.S. government and published in the journal Nature Biotechnology, has added to the evidence that pest resistance to genetically modified (GM) crops has been rising dramatically for decades. The study, which examines 20 years of data, focused on a specific class of GM crops that have been bioengineered to produce insect-killing proteins naturally produced by the Bacillus thuringiensis (Bt) bacterium.
