Opposition to hunting is espoused by people or groups who object to the practice of hunting, often seeking anti-hunting legislation and sometimes taking on acts of civil disobedience, such as hunt sabotage. Anti-hunting laws, such as the English Hunting Act 2004, are generally distinguishable from conservation legislation like the American Marine Mammal Protection Act by whether they seek to reduce or prevent hunting for perceived cruelty-related reasons or to regulate hunting for conservation, although the boundaries of distinction are sometimes blurred in specific laws, for example when endangered animals are hunted.
