Pack animals are domesticated animals used to carry loads, making them essential for transportation and trade in many cultures. Common examples include horses, donkeys, mules, and camels. These animals are trained to carry heavy packs on their backs, allowing people to transport goods over long distances, especially in rugged terrains. Using pack animals can be more efficient than vehicles in certain environments, such as mountains or deserts. They can navigate narrow paths and rough landscapes where trucks or cars cannot go. This practice has been vital for communities that rely on agriculture and trade in remote areas.
