What is the potential environmental impact of improper pesticide disposal?

Improper pesticide disposal can lead to soil and water contamination, making this the correct answer. When pesticides are disposed of inappropriately—such as pouring them down drains, onto the ground, or in regular household garbage—they can leach into the soil and eventually seep into groundwater or surface water bodies. This contamination can harm aquatic ecosystems, disrupt food chains, and pose health risks to humans and wildlife through exposure to toxic chemicals.

Additionally, the chemicals in pesticides can alter soil chemistry and affect beneficial microorganisms, which play crucial roles in maintaining soil health. This could result in diminished soil fertility over time. Drinking water sources can also be affected, creating potential health hazards for communities that rely on those resources.

The other options do not reflect the serious consequences that can arise from improper pesticide disposal. While it may seem tempting to think that such actions could enhance soil health or have no significant impact, both notions are misleading. Similarly, the idea that it only affects indoor plants ignores the broader implications for environmental health and safety.
