**Animals Used for Earning a Livelihood**

Animals have been used by humans for various purposes since ancient times. They have played a significant role in helping humans earn a livelihood in different ways. Let's explore some of the animals that have been traditionally used for this purpose.

**1. Cattle:**
Cattle, such as cows and buffaloes, have been used by humans for centuries to earn a livelihood. They are primarily used for milk production, which is a valuable source of nutrition and income. Milk is consumed by people directly or is processed into various dairy products like butter, cheese, and yogurt.

**2. Horses:**
Horses have been used for transportation, agriculture, and even in warfare. In the past, horses were used as a means of transportation before the invention of cars and motorcycles. They were also used for plowing fields and pulling heavy loads. Additionally, horses were an essential part of cavalry units in ancient armies.

**3. Donkeys and Mules:**
Donkeys and mules have been used in areas with rough terrains or in rural areas where motorized vehicles are not easily accessible. They are known for their strength and endurance, making them suitable for carrying heavy loads. Donkeys and mules are often used for transporting goods, especially in mountainous regions.

**4. Dogs:**
Dogs have been domesticated for thousands of years and have served humans in various ways. They have been used for hunting, herding, and guarding livestock. Dogs are known for their loyalty, intelligence, and ability to assist humans in different tasks. They continue to be used in various working roles, such as search and rescue, therapy, and even as guide dogs for individuals with visual impairments.

**5. Bees:**
Bees are not mammals, but they are also important for humans as they provide honey, beeswax, and pollination services. Beekeeping is a practice where humans maintain beehives to collect honey and beeswax. Honey is not only consumed as a sweetener but also has medicinal properties. Bees also play a crucial role in pollinating plants, which is essential for the growth of fruits, vegetables, and crops.

In conclusion, animals have been an integral part of human civilization and have been used for various purposes to earn a livelihood. From providing milk and transportation to assisting in farming and guarding, animals have played a vital role in supporting human activities and enhancing their quality of life.
