What might be an immediate consequence of pesticide drift?

The immediate consequence of pesticide drift is the exposure of non-target organisms to pesticides. Pesticide drift occurs when pesticides are carried away from the intended application area by wind or other environmental factors, resulting in unintentional exposure to plants, animals, and even humans that were not meant to be part of the treatment.

When non-target organisms come into contact with these chemicals, it can lead to harmful effects such as toxicity, behavioral changes, or disruption of local ecosystems. This is a significant concern for environmental health advocates and regulatory agencies, as it poses risks not only to wildlife but also to beneficial insects that might be critical for pollination or pest control.

The other options do not accurately reflect the scenario: improved health for nearby plants is unlikely if they are exposed to harmful pesticides; increased pest populations might occur over time due to resistance but is not an immediate consequence; and while there may be instances of no observable effects, lingering effects or toxicity can often be seen after drift occurs, making this option less plausible.
