Animals are creation of ALLAH just like humans. They also have emotions and feel equal pain as humans and are the part of our society. Now a days human treat animals as there slaves though animals play a vital role in our society we use animals for our transportation, in different games like polo, horse racing etc, as our pets, for security purposes and as food.
They also feel like human except they cannot express there feeling with the help to language. We also know that Humans are superior to animals but animals contribute a lot to our economy like industries which uses animals as there source of production which includes diary, meat, and clothing. Animals like goat and cow produces milk which is a need of every human and provide essential nutrient which is easily being digested by any age group. But on the other hand we use animals as our experimentation of different operations and medicines to know the side effects and all that stuff. We know that doctors or scientist do these experimentation for the betterment of humans but there should be other alternative ways to achieve improvements.
According to my opinion animals we should stop all pharmaceutical companies from doing trials on innocent animals and use alter ways to achieve goals it is not fear to put animals into mental suffering or distress.
