Pesticides, rodenticides, and other chemicals poison wildlife directly and through secondary toxicity. Understanding these pathways helps identify the most impactful welfare interventions.
Wildlife poisoning is a welfare crisis that is largely invisible because affected animals typically die out of sight, and sublethal effects are difficult to detect without systematic monitoring. The mechanisms are well understood, and the interventions — alternative rodenticide approaches, restrictions on harmful pesticides, lead shot phase-out — are technically and economically feasible. The barrier is primarily regulatory and political. Consumer and advocacy pressure for restrictions on the most harmful chemicals is an important complement to regulatory action.
