What could potentially cause disease in wild bunnies?

Famine and drought can significantly impact the health and survival of wild bunnies. When food sources become scarce due to famine, bunnies may experience malnutrition, leading to weakened immune systems, making them more susceptible to diseases. Drought can reduce the availability of both food and water, further exacerbating the health risks for these animals. Adequate nutrition is vital for maintaining a robust immune response, and when bunnies cannot obtain sufficient resources, they face an increased likelihood of illness.

The other factors, while they can influence the environment and habitat of wild bunnies, are not as directly tied to disease causation. For instance, excessive rainfall might lead to habitat changes but doesn’t necessarily induce disease unless it causes conditions for a specific pathogen. High temperatures can impact behavior and availability of resources but, much like rainfall, don’t have a direct correlation to disease. Overpopulation could lead to increased competition, and potential stress, but the primary concern related to disease emergence often centers on resource availability, which famine and drought directly provoke.
