Over the past few years, it has been ferociously observed that the food habit which are seen as sacred and normal in one religion or society has always offended the other religion or community. And now, there is one more angle to it, which is of sustainability and animal cruelty on a particular food habit. These 2 doctrines are seems to politicize our food habits in today's world (referring to the beef politics in India, dog meat festival and topics raised in the Leonardo DiCaprio's documentary). It is a point of discussion therefore, that what should/shouldn't be followed in the case like this which is also related to our basic survival or it should be just left to the most basic dogma i.e. "survival of the fittest".
