What statement is correct regarding the impact of pesticides on surrounding ecosystems?

The statement regarding the impact of pesticides on surrounding ecosystems that is correct is that pesticides can harm beneficial organisms. Pesticides are designed to control or eliminate targeted pests, but their chemical properties often do not discriminate between harmful and beneficial organisms. For instance, pollinators like bees, beneficial insects that control pest populations, and organisms that contribute to soil health can be negatively affected by pesticide use. The residues from pesticides can drift from treated areas, leading to unintended contact with non-target species, which can disrupt ecological balance and biodiversity.

In contrast, the other statements are misleading or inaccurate. The assertion that pesticides have no effect is incorrect because there is extensive evidence showing their broader impact on ecosystems. Claiming that pesticides only impact targeted pests overlooks the reality that many substances harm a range of organisms. Additionally, the idea that pesticides should only be used indoors disregards their extensive application in outdoor environments, which is often necessary for managing pests affecting crops, lawns, and ornamental plants. Thus, the correct interpretation highlights the potential for pesticides to also unintentionally harm beneficial organisms within the ecosystem.
