"She said if the moose cow had been killed under natural circumstances she would understand the park's stance. But she doesn't think that applies in this situation. "Since it was a human being that killed the mother, it's a human being that should take care of the calves," Parslow said."

Newsflash, human beings are part of the natural ecosystem. We're often  bad actors, but we are just as much a "natural circumstance" as any other predatory attack. Our actions do seem deplorable to those gazing upon an adorable orphaned moose, but scavengers have been living off humanity's actions for thousands of years.
