By 2050, there could be up to 10 billion people on Earth. Commercial agriculture allows for large quantities of crops to be grown and distributed worldwide. A company sells an herbicide called Gro-No-Mo, which kills all weeds in a grower's field but does not harm their crops. However, after three years of spraying the herbicide, the grower noticed that Gro-No-Mo was not as effective as when he started using it, and weeds seemed to be growing stronger.

Next to the grower's farm is a city water reservoir. Residents have started to notice an unusual odor and taste coming from their water faucets, and there has been a spike in children being hospitalized for digestive disorders. Populations of honeybees have fallen, and there are less beneficial insects and worms in the soil.

From the scenario, what is another consequence of spraying the herbicide Gro-No-Mo?
a. It makes the soybeans taste weird
b. There are no consequences
c. It may be the reason why other organisms may be dying
