What if your pets / other animals started indicating what they want to you, in an explicit manner? Would that help? This thought occurred to me while having a look at a painfully overloaded bull pulling a bullock cart during one of the religious processions in India.
Why do people make animals work like slaves beyond any means? A good question to ask is, will people stop cruelty towards animals such as exposing animals to huge workloads, excessive noise pollution that happens during festivals in India related such things.
Another interesting thought is, will the pet animals become more friendly if one can understand their body language in more explicit way. For example, your dog wags his tail as a sign of some affection. Would it be better to understand what is on his mind? Now, to understand this question another question to understand is, does a dog really has a mind? Now if we are some how able to transform an animals emotions into an understandable form? Will that help us communicate better or build more complexities in our relations? For example. many people in America keep pets as a sole reason because pets provide you unconditional love without expectations to return it back to you. Human relations are complex. If you have a girlfriend, she would want your attention in terms of spending your time with her, be emotionally available to her, pamper her etc etc. A dog does not expect all these things in an explicit manner, now its a different matter altogether if he might be really expecting these things, but not able to communicate it effectively, so the expectation stays dormant. However, some analysis says, since he is always there for you when you are back home, he loves you unconditionally without expectations. If you have a wife / girlfriend with whom you would do such behaviour chances are that she would divorce / break up with you soon, because she is a human and have definite expectations from you.
So if we are able to build such a devise by which these animals are able to express their emotions, would it complicate humans relationship with them? Like your dog would then be able to say, "Why didn't you not return home today, when I wanted you to return to take for a walk :)". This is an interesting question.
Now turning back to the bull story, even if we had such an expressive device I do not feel it would help to stop cruelty towards these animals, who suffer in muteness, because these acts are committed by selfish people who are just interested in making most out of their resources. An animal is just one of the resource for them. When humans are treated so pathetically at many working places (for example barbaric acts committed during slavery period in Africa), did their committers stop because these people protested? No, in fact they committed even more atrocacies like rape, murders to teach these people better psychological lessons to live under a constant threat. So my stake is even if we were able to form such expressive device, it will not be of any help, because these acts are committed for a purpose of greed, which is very difficult to control.
So I feel these atrocacies on animals will continue and poor animals would continue to suffer in silence.
