Man is superior to the rest of the creation simply because of his superior wisdom. Even birds and animals have wisdom but their wisdom is very much limited as compared to that of man. Man certainly misuses his this blessing of wisdom when he tries to exterminate other species of life just to satisfy his ego of palate of the tongue, and furthermore when tries to cover such sinful acts by vague and frivolous reasoning. It is clear that he has no solid and sustainable justification for his actions and is just trying to beat about the bush
