Question: 1 / 400

What is the greatest impact of humans on wildlife populations?

Introduction of new diseases

Habitat change and influence

Humans have the greatest impact on wildlife populations through habitat change and influence. This includes deforestation, urbanization, and land development, which destroy and fragment natural habitats, forcing wildlife to adapt or move to new areas. This can lead to competition for limited resources, reduced genetic diversity, and altered ecosystems. While options A, C, and D can also have an impact on wildlife populations, they are not considered the greatest impact compared to habitat change and influence. Introduction of new diseases, pollution, and noise creation can all have significant consequences for wildlife populations, but their effects are usually more localized and specific. For example, disease outbreaks may affect certain species or populations, pollution may affect only certain habitats, and noise creation may only impact wildlife in the immediate vicinity of human activities. Therefore, these options are not deemed as the greatest impact of humans on wildlife populations.
