What can be a long-term consequence of applying pesticides?

Applying pesticides can lead to the long-term consequence of their persistence in the environment. Many pesticides are designed to be effective over a certain period, but this can mean they remain active long after their initial application. This prolonged presence can have various ecological impacts, such as contaminating soil and water sources and disrupting local ecosystems.

In contrast to the other options, which suggest that pesticides unconditionally improve soil quality, have no impact on wildlife, or are always non-harmful to humans, the reality is much more complex. Pesticides can degrade soil health, affect biodiversity, and pose risks to human health due to exposure to residual chemicals. The information about their lingering effects highlights the need for careful management and consideration of alternatives in pest control to mitigate these long-term environmental consequences.
