This paper will present several principles of the Food Ethics, possible criticism for this approach as well as refutation of it.
First of all, it would be highly important to provide a general perspective on the issue. Thus, one would not make a mistake pointing out that among the food that people consume there are certain groups of products that are different from others. For example, if pigs have been domesticated from numerous centuries and the production of their meat has been developed in great detail, there are some animals which are also consumed, but their meat or other parts of the body have been introduced to the people relatively recently. In addition to that, some meat might come from the animals the population of which is far less than the one of pigs or cows. Finally, the development of the science has brought up a new category of food which consists of Genetically Modified Organisms. So, the primary question focuses on the idea whether people have a moral duty to support certain food.
Since the above mentioned question lies in the realm of Ethics, it would be logical to use several Ethical Theories than are relevant in this case. The first approach that is able to provide an answer to this problem is the Kantian Ethics. Thus, according to it, people should be considered to be responsible for the preserving of the wildlife as well as fragile ecosystems around the world and, therefore, they should never consume flesh of the animals that are endangered. In addition to that, since food that is made of Genetically Modified Organisms might be harmful to the bodies of the people, it should not be introduced to the market in any form.
However, a completely different approach is presented by the Utilitarian Ethics. Indeed, it argues that there is no problem in eating meat of the endangered animals or the meat that was produced in a cruel way as long as it pleases the people and they are able to cope with the consequences of it.
