How to become a vegetarian
How I did it: Realistically, I probably made the transition gradually without even realizing it. When I was younger, I stopped eating red meat. I didn't like the tast of it, and I felt it wasn't that good for me anyway. So, this is what I cut out first. Over the next few years, I gradually just stopped eating, chicken, pork, etc. Not out of any moral concern, really. It was more of a health thing and knowing how my body felt. I still ate meat products occasionally, but most of it was limited to fish. I think this gradual elimination of meat products mad it easier for me to make the decision when the time came.
When I did finally make the decision to cut out meat and meat products entirely it was for moral, environmental, and health concerns. I just stopped eating all meat. Seemingly, I made the transition overnight. As I said, however, it was actually a process that I'd started years ago, albeit unconsciously. It's been about a year and a half since I've become vegetarian. I do get tempted by meat products occasionally, but my resolve is strong because I know all the good I'm doing for the world with my decision!
