The Essential Role of Animals in Human Life

Animals in Human Nutrition

• Animals are a primary source of protein in human diets, with meat, dairy, and eggs providing essential amino acids.
• Livestock, such as cattle, pigs, and chickens, are raised for meat consumption, while aquatic animals, like fish and shrimp, are harvested for seafood.
• Animal products, like milk and eggs, are rich in micronutrients, such as calcium, vitamin D, and B vitamins.

Animals in Medical Research

• Animals are used as models in medical research to study human diseases, test treatments, and develop new medicines.
• Similarities between animal and human physiology enable researchers to draw conclusions about human health from animal studies.
• Animal testing helps to ensure the safety and efficacy of new drugs and treatments before they are approved for human use.

Animals in Agriculture

• Animals are used for labor in agriculture, such as oxen and horses for plowing and transportation.
• They provide manure, a natural fertilizer, which enriches soil and promotes plant growth.
• Bees and other pollinators are essential for crop reproduction, increasing yields and food quality.
