Which of the following is a potential consequence of improper pesticide use?

The potential consequence of improper pesticide use is environmental contamination. This outcome can arise when pesticides are applied incorrectly—whether through overapplication, drift, or improper handling and disposal. Such practices can lead to pesticides entering soil, water sources, and air, adversely affecting ecosystems, wildlife, and human health. Contamination can result in long-term ecological damage, affecting not just the immediate area but also distant environments through water runoff and air currents.

In contrast, options like increased crop yield, cost savings for farmers, and enhanced soil fertility typically relate to responsible and effective pesticide use rather than improper application. While it might be possible to temporarily achieve higher yields or save costs through reckless pesticide practices, the long-term ramifications often include negative impacts that far outweigh any short-term benefits.
