scientists have genetically engineered crops to be resistant to herbicides. this allows farmers to kill weeds with small doses of herbicides that don’t harm the crops. why, then, are people concerned that transgenic plants may lead to an increase in the use of herbicides?
cross-pollination could cause the crops to lose their herbicide resistance.
weeds may naturally develop herbicide resistance with each dose.
herbicide-resistant crops may grow out of control and become weeds.
cross-pollination could pass herbicide-resistant genes to the weeds.
