Why do elks deer and antelopes have to protect themselves?

Elks, deer, and antelopes must protect themselves primarily to survive against natural predators, such as wolves and big cats. Their survival adaptations, including speed, agility, and keen senses, help them evade threats in their environments. Additionally, they face risks from human activities, such as hunting and habitat loss, which necessitate further protective behaviors. Overall, self-defense is crucial for their longevity and reproductive success.
