Final answer:
The statement is true as a healthy presence of wildlife generally indicates a healthy environment with well-functioning ecosystems that benefit human health and psychological well-being, per studies in Environmental Biology and the work of E. O. Wilson.
Step-by-step explanation:
The statement that a healthy presence of wildlife also means a healthy environment is generally true. Wildlife health is a strong indicator of the overall health of an ecosystem. A biodiverse environment with a robust population of various species suggests that essential abiotic factors such as water quality, air quality, and nutrient cycles are functioning properly. Additionally, biodiversity is crucial for ecosystem productivity, where each species, no matter how small, has an important role to play. Environmental Biology studies show that the health of human populations is closely related to the health of our environment, which includes the wildlife present. A healthy natural environment provides many benefits, including adequate nutrition from a diverse and natural diet, and psychological well-being derived from interacting with a biodiverse world. The concept, championed by entomologist E. O. Wilson, emphasizes that human evolutionary history is closely linked to natural environments and that urban environments lacking biodiversity can contribute to stress and harm to human health and well-being.
