Of these choices, we have no idea of the moral consequences. We simply don't know. But then, what would we know about the moral implications? We can't know whether slaughtering animals for meat is morally permissible; perhaps it is wrong for some religious or philosophical reasons. (Imagine a sacrilegious cause to be the one thing on which two religions disagree.)
Suppose that I grew up as a vegetarian and awoke one day to find myself in a food-producing society. Perhaps I'm an ahistorical, 21st-century, secular person, who has never encountered a slaughterhouse or looked at meat or knew what a butcher looked like. Then, I must discover that there are animals in my neighborhood—how many? And what are they doing? How do I relate to them?
The questions of how one can be a pescatarian, vegetarian, vegan, or any other type of ethical practice are very difficult to grasp in terms of names, specifications and rules. Ethics in general is an abstract and vague concept.121 Ethics usually involves a combination of dualistic and non-dualistic frame that conditions the person in a particular situation, culture, and knowledge.122 The question as to where and when it is reasonable to use animals as food or not is an ethical question.123
More importantly, we need to recognize that the ethical issues concerning the use of animals in food production are complex and there are several layers of considerations to take into account.124 This is because ethics involves abstract concepts of the values, for example, moral is an abstraction of fact (which of kinds of things can be used for human purposes). Ethical behaviour is complex. 125 Use of animals or substances which are not plants for human purposes has differed over time and depended upon different cultures of different times and places.6 In order to have a flourishing life requires ethical behaviour.126 In this sense, ethics concerns the good life as a whole. However, in this study, the author mostly focuses on the bad life (in terms of the mental and physical health) caused by the use of animals in food.127 d2c66b5586
