Taking a critical look at one's own meat consumption can be enlightening, because it is something that we often take for granted. Do I eat meat because it is necessary for my health? If not, what are the reasons? How is the meat that I'm eating produced? How long do these animals live compared to their natural life span? What is the environmental cost of animal farming? Etc., Etc.
I did not find convincing answers to these questions, so I stopped buying and eating meat.
