Environmental toxins, such as heavy metals and pesticides, significantly impact wildlife populations. These substances can cause physiological and reproductive harm, often leading to population declines. Wildlife exposed to toxins may exhibit weakened immunity, reduced fertility, and developmental issues in offspring. Additionally, bioaccumulation can occur, where toxins concentrate in the food chain, affecting top predators most dramatically. The long-term consequences include altered ecosystem dynamics and loss of biodiversity, indicating a pressing need for conservation efforts and stricter regulations on toxins.
