The following passage discusses the climate in northern regions and its impact on wildlife:
In the harsh climates of northern areas, where winters last long and temperatures can plummet drastically, various species of wildlife have adapted unique traits to survive. These adaptations include thicker fur coats in mammals, changes in feeding habits, and even altered migration patterns.
Despite such adaptations, many of these species face increasing threats due to climate change. As the climate shifts, their habitats are changing too, often resulting in food scarcity and increased competition among species.
Which of the following revisions to the last sentence of the passage most effectively clarifies the connection between climate change and the challenges faced by wildlife?
