One concern regarding transgenic crops that produce pesticides is that this trait may:

The concern surrounding transgenic crops that produce pesticides primarily focuses on their potential ecological impact, particularly concerning non-target organisms. When transgenic crops are engineered to produce specific pesticides, those chemicals may not only affect the intended pest species but also harm beneficial insects that play crucial roles in ecosystems, such as pollinators and natural pest regulators. This is particularly worrying because the loss of these non-target species can lead to longer-term ecological imbalances, resulting in reduced biodiversity and the breakdown of natural interactions within ecosystems.

If beneficial insects are impacted by these pesticides, it could lead to increased pest populations over time, as their natural predators are diminished. Such unintended consequences can undermine the goals of using genetically modified organisms (GMOs) for pest management and raise concern about the long-term sustainability of agricultural practices. This ecological concern highlights the importance of evaluating the broader effects of transgenic crop technology beyond just pest control efficiency.
