4. Medicine extraction

Animals are used to extract useful medicinal molecules. In recent times, this method is mostly replaced by biotechnology. Still, some drugs are especially obtained from animals. Ex. Heparin, an anti-coagulant used to control clots in the blood, is collected from ox lungs and pig intestines. Even insulin was previously isolated for people with diabetes from buffalo and pigs pancreatic cells. Similarly, we obtain vitamin-D from shark liver oil.

5. Leather

Animals are a great source of leather. This leather is used for making footwear, belts, wallets, bags, furniture, etc. The animals used for extracting their hide for leather include buffaloes, cows, ox, etc. This leather is tanned and made suitable for making the above articles after obtaining it from animal hide.

In developing countries still, animals are used in large numbers for farming. They are specifically used for farming the land, transport by bullock-carts by farmers.

They are also used for pumping the water from the river and ponds into the farms.

Natural farming experts also recommend the use of animals for farming instead of heavy machines like tractors.

As per them, heavy tractors would destroy the soil layers. The density of soil increases and soil air is reduced. This causes harm to the farm. Animals used in the place of those machines would not cause such harm.

Also, animals feed on the vegetation grow on the farm, like the husk of wheat, rice, etc. and survive without the need for extra cost for the farmer.

Hence, the use of animals for agriculture would save the cost of farming and also minimize the chances of pollution.

10. Animal for manure

Animals are also kept for the sake of organic manure. The dung of cattle is very good for farms as it imparts rich fertility to the soil.

The litter droppings of the sheep staying on the farm add a lot to soil fertility.

11. Education

Animals are quite a part of our education. In science-related subjects and courses, we use animal specimens, live or even dead animals, to study their body function and structure to understand better and gain knowledge. Also, one can understand their body physiology when comparing with animal physiology. Routinely we use animals like insects, amphibians, earthworms, rodents, reptiles to study.

12. For medical testing

Importance of Animals | 13 Uses for Human Life (5)

Any new medicine discovered is taken for pre-clinical studies before testing on man. Here the animal testing is done on animal cells, tissues, organs, or whole organisms. This helps them to evaluate the actual effects of drugs. This way, the toxic drug effects, mechanism of action, side effects, maximum tolerable dose, etc., are noted.

Smaller animals, especially rodents like rats, mice, rabbits, guinea pigs, are used for the purpose. For this, there are some stringent rules to be observed by the researchers to minimize animal suffering. Big animals are mostly prohibited for use as they induce much waste and are also ethically debated. By much waste, it means the use of one dog can create an equal waste of using 50 rats. So now you can guess why…?

13. For drug manufacture

Animals like horses, mice are used for the production of essential medicines. Horses are used to produce snake anti-venom, which can rescue the life of humans when there is a snake bite. Similarly, mice are used to create a variety of monoclonal antibody production.

In horses, snake poison is injected into horses. The body of a horse produces anti-venom, which can counter the snake poison. After a few days of injection, the horse blood is collected for isolation of anti-venom.

Because of the advantages mentioned above, we humans need to strive for animal welfare.
