Final answer:
Arguments for closing elk feed grounds include overpopulation, disease spread, and alteration of natural behaviors, while reasons to keep them open involve supporting recreation, protecting elk from winter, and managing human-elk conflicts.
Step-by-step explanation:
Arguments for closing elk feed grounds might include concerns about overpopulation, disease transmission, and disruption of natural behavioral changes and migration patterns. Overpopulation can lead to habitat degradation and increased competition for resources. Congregation of elk at feed grounds can facilitate the spread of diseases like chronic wasting disease. It can also disrupt natural behaviors related to seasonal and physiological changes, which are important for maintaining ecological balance.
On the other hand, arguments for keeping the feed grounds open might focus on the states' interest in maintaining high elk populations for hunting and viewing, protecting the elk from harsh winter conditions, and potentially decreasing human-elk conflicts by providing a controlled environment for feeding.
