What is one consequence of overusing pesticides?

One significant consequence of overusing pesticides is the development of pesticide-resistant pest populations. When pesticides are applied frequently or in high doses, some pests may survive the exposure due to genetic variations that confer resistance. These surviving pests then reproduce, leading to a new generation that is largely resistant to the pesticide used. This dynamic creates a cycle where farmers may need to use even stronger or different pesticides to manage these pests, potentially leading to increased chemical use and environmental impact.

Additionally, the resistance can limit the effectiveness of essential pest management strategies and can jeopardize agricultural productivity, posing a significant challenge to sustainable farming practices. As resistant populations grow, it becomes harder to control pest outbreaks, necessitating further intervention which can lead to a greater reliance on chemical solutions rather than integrated pest management practices.
