I was slightly concerned about the meat itself such as accurate labeling (especially fish) and additives/hormones/antibiotics/plastics/metals. But my bigger concern was the negative externalities. For example, the overuse of antibiotics contributing to antibiotic-resistant diseases. The greater environmental impact in terms of water/land/carbon. The manner in which animals are raised and slaughtered, especially in large-scale farms. The sustainability of fish stocks. Several years back I started only eating meat from a couple local farms which addressed most of those concerns, but the cost meant that meat became more of a "special occasion" thing. I didn't go vegetarian (for example I tried the pork at our local farm's pig roast last month) but over the last few years it's just sort of happened that I eat meat less frequently, now a few times a year. So far I haven't particularly missed it from a taste or health standpoint.
