Answer:
One with a wide variety of wildlife
Explanation:
Wildlife includes animals, plants, fungi and more. All those wildlife has their role to play in the ecosystem to maintain the balance and health of the environment. Without sufficient variety of wildlife that have specific niches to contribute to the environment, the environment will degrade and lose its balance, causing disasters like landslides, drought related floor cracks and more.
Hence, as the other 2 options of lacking wildlife variety and an environment that recently experienced Crown fires means that wildlife quantity and quality has decreased whereby the latter basically results in wildlife being burnt to death, the environment will no longer be healthy due to the huge decrease in wildlife with niches to contribute to the balance of the environment.
