The main impact of pesticide use on wildlife includes toxicity, the disruption of food chains, and the decline of biodiversity. Pesticides can adversely affect non-target species, including insects, birds, and aquatic life, leading to population declines and ecosystem imbalances. Furthermore, bioaccumulation and biomagnification can occur, where toxins concentrate in the food web, harming predators and reducing species resilience. The long-term consequences of pesticide use highlight the need for sustainable agricultural practices that minimize chemical reliance while promoting ecosystem health.
