Answer: Greater use of pesticides destroys the crops and useful organisms.
Step-by-step explanation:
The loss of non targeted organism leads to increased use of pesticides because the targeted organism will still be there to harm the crops.
Again the pesticide will be used until the targeted organism dies. But there is no guarantee that the target organism will die if they are not targeted.
So, more and more pesticides will be harmful for the crops and other useful insects and pests.
