Answer:
BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops
Step-by-step explanation:
The correct answer is BT-modified crops may kill pollinators, reducing crop fertility in seed and fruit crops. People would prefer that beneficial pollinator species become BT-immune. There is little concern about cross-genus exchanges of genetic material leading to BT-toxic bee stings, or that pollinating species will come to prefer BT-modified crops and ignore natural, unmodified crops.
