The Mutant Strength of GMO Corn: Even if GMO corn were safe on all other fronts (and research suggests it’s not), using the uber-tough corn is a calculated risk. Super-strong corn stalks are wreaking havoc on tractor tires by poking into their surfaces. The laboratory corn is so strong that farmers are resorting to kevlar, the material used in bullet-proof vests, for their tractor tires!
Farmers might see fewer crops lost to bugs and drought, but they’ll pay for it in farm equipment - tires cost, on average, a couple of a hundred dollars apiece. Mark Newhall, editor of Farm Show magazine, says that the stalks are so tough that “when you cut them off to harvest them, it’s like having a field of little spears.”
