Few individuals believed that using animals body for experiments purpose are not good due to some reasons according to them. On the other hand side. other people views that precious studies of many scientific theories and dicoveries becoming possible due to the use of animals bodies. So. i completely acepet this view of using animals for more new discoveries and advancements
Argubaly. human is more precious then animals because human beings have congnitive mind and thinking. So their output in sense of positivity. supreme leading become possible while in animals itsI not. Also humans performed different activities while animals have limited things to do a specific task. for example a horse and donkey is useful only for travelling and loading luggages purposes. Cows. chikens. rabits and so on have limited actions to do their jobs.
Morover. using animals for experiments purpose is tottaly fine because we never sacrifice a human life. In my Personal experience. I remember when i was in college life. i have a practical session in which i have to performed a disection of frog because frog digestive system is very similar to human being. so its easy to perform on frog rather than a man. furthermore. many laborities testing becoming posiible by the usage of animals. like rats. rabbits etc.
Also. Most of the time animals need for medicine testing in pharmacology industry. Many diseses required a live for experiment usage. So its better to sacrifice an animals instead of human.
So. for that reasons I personally believed that in the advamcement of medical and treatment of human being we use animal as a sourse person to tactte the challenges in sense of diseses and testing purposes.
