Why can walls that block wildlife movement harm conservation?
Answer and explanation
Correct answer: They can block access to food, breeding sites and other populations, reducing genetic exchange
Walls can fragment habitats and prevent animals from reaching food, water, breeding sites and other populations. This reduces breeding opportunities and gene flow, and may increase the risk of inbreeding in small populations. Option B is incorrect because walls block rather than improve wildlife corridors. Exam tip: habitat connectivity and wildlife corridors are key ideas in conservation.
