Why is it important to collect and destroy carcasses of target animals?

Collecting and destroying carcasses of target animals is crucial to avoid secondary poisoning hazards to non-target animals. When target animals are poisoned, their carcasses can still contain toxic substances. These toxins can be ingested by scavengers or other animals that consume the carcass, leading to unintended poisoning and potential death of these non-target species. This practice helps maintain the balance within the ecosystem by preventing harm to beneficial wildlife that may rely on these areas for food.

In this context, while preventing disease spread among animals is significant, the foremost concern in the scenario of carcass management is the risk to non-target animals. The other options touch on important pest management and environmental concerns but do not directly address the immediate issue of secondary poisoning, making them less relevant to the specific question about the importance of carcass management in this situation.
