Q.Discuss briefly the importance of animals to human kind.

Animals are far more than companions in our world — they are woven into the very fabric of human survival and progress. Their importance spans food, work, medicine, and culture, and each role is worth understanding clearly.

• Food and nutrition: Animals provide milk, eggs, and meat, which supply essential proteins, fats, and vitamins that plant-based diets alone cannot fully replace.
• Work and transport: For centuries, animals like oxen, horses, and donkeys have ploughed fields, carried loads, and moved people — still vital in many rural economies.
• Clothing and materials: Wool, leather, and silk come directly from animals, giving us warmth, protection, and durable goods.
• Medicine and research: Many life-saving drugs, from insulin to certain vaccines, are derived from animal sources or tested on animals to ensure safety before human use. …

Think about a single ordinary day. The milk in your tea, the leather on your shoes, the wool in your sweater, the vaccine that protected you as a child — each of these traces back to an animal. Long before we had machines, we had animals: they pulled our ploughs, carried our goods, guarded our homes, and warned us of danger. In many parts of the world, that partnership is not a memory but a daily reality. A farmer in rural India still depends on his bullocks for tilling, his cow for milk and dung, and his dog for protection. Remove animals from that equation, and the entire rural economy would collapse overnight.

Economically, animals are a living bank. Livestock provides a steady income through milk, eggs, wool, and meat, and acts as a safety net in times of crop failure — you can sell a goat or a buffalo when the harvest fails. The leather, silk, and honey industries employ millions. In India, animal husbandry is not a side activity; it is a major pillar of the rural economy, supporting landless labourers and small farmers who own just a few animals. The dung of cattle is not waste — it is fuel, fertilizer, and even a building material in many villages. Nothing is thrown away; everything is cycled back into human life.

Then there is the realm of health. Many life-saving medicines — insulin, certain hormones, vaccines, and antitoxins — are derived from or tested on animals. The snake that frightens us yields venom that becomes antivenom; the horseshoe crab's blood is used to test the safety of injectable drugs. Animals have served as models for understanding human diseases, from diabetes to heart conditions. Without them, modern medicine would be decades behind. This is not sentiment; it is a hard, practical dependence.

Culturally and psychologically, animals enrich us in ways that are harder to measure but no less real. They appear in our myths, our religions, our art, and our festivals — think of the elephant-headed deity, the cow as a symbol of motherhood, the eagle as a sign of freedom. Pets reduce stress, lower blood pressure, and give companionship to the lonely. For a child, a pet is often the first lesson in responsibility, empathy, and the cycle of life and death. These are not trivial benefits; they shape who we are as human beings. …
