Final answer:
Euthanasia of large animals can prevent hazards related to zoonotic diseases, which are diseases that can be transmitted from animals to humans, especially when human-animal interactions increase due to habitat loss and encroachment.
Step-by-step explanation:
The euthanasia of large animals can help prevent specific hazards related to zoonotic diseases. Zoonotic diseases are those that can be transferred from animals to humans. Situations causing an increase in the interaction between wildlife and humans, such as habitat loss and settlement of wild areas, can elevate the risk of disease transmission.
When considering large animals, overpopulation can contribute to an increase in direct human contact from encroachment into wilderness areas or through vectors such as mosquitoes. Moreover, overpopulation of large animals like elephants can lead to ecological imbalances, contributing to increased conflict with humans and potential spread of diseases.
Additionally, when ecosystems are altered and large mammals disappear, disease transmission risks can change, and other consequences, such as trophic cascade effects, can occur.
