Answer: Claim - Wolf populations close to human populations can decline.
Explanation: Wolves are top level predators and even today, humans are fearful of contact with such animals. Modern humans routinely kill wolves, due to the threat they pose to human populations and their livestock. For this reason, wolf populations close to human populations can decline.
As the human population continues to expand, the area habituated by humans expands as well. As humans inhabit more and more of an established ecosystem, the flora and fauna suffer. Humans interrupt migration patterns, loss of living habitats, and loss of food for Grey wolves.
